Its real\u2011time database, authentication suite, and cloud functions have powered countless mobile and web applications. However, as projects grow, many developers hit Firebase\u2019s limitations: vendor lock\u2011in, proprietary query languages, scaling costs, and the inability to run complex relational queries. Enter Supabase \u2013 an open\u2011source BaaS that positions itself as a direct Firebase alternative. Supabase is built on top of PostgreSQL, giving you a mature, ACID\u2011compliant relational database from day one. It offers real\u2011time subscriptions, authentication, file storage, and edge functions, all while being fully self\u2011hostable or managed via the cloud. In this comprehensive tutorial, we will walk through every major feature of Supabase, from setting up your first project to implementing authentication, row\u2011level security, real\u2011time data, and file storage. By the end, you\u2019ll understand not only how to use Supabase but also why it may be a better fit for your next project.<\/p>\n<p>Before we dive into the steps, let\u2019s quickly address the elephant in the room: why replace Firebase with something else? Firebase\u2019s Realtime Database and Firestore are NoSQL document stores. While flexible, they force you to denormalise data and think in terms of document hierarchies. Complex joins, aggregations, and transactions become painful. Supabase, by using PostgreSQL, lets you harness the full power of SQL: foreign keys, indexes, views, and advanced functions like full\u2011text search. Moreover, Supabase\u2019s core is open\u2011source \u2013 you can inspect the code, contribute, and even run your own instance on your own infrastructure if you need to. The skills you learn (SQL, Row\u2011Level Security, relational modeling) are transferable to any modern backend stack. Let\u2019s start by getting your hands dirty with a real project.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/07\/article-1783098077514.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>Step 1: Setting Up a Supabase Project and Connecting to PostgreSQL<\/h2>\n<p>Your journey begins at <a href=\"https:\/\/supabase.com\">supabase.com<\/a>. Sign up for a free account \u2013 you\u2019ll get two projects that include 500 MB of database storage and 2 GB of bandwidth each, more than enough for prototypes and small applications. Once logged in, click \u201cNew project\u201d and give it a name (e.g., \u201cmy\u2011supabase\u2011app\u201d). Choose a secure database password \u2013 you\u2019ll need it if you ever want to connect directly via a SQL client. Select a region close to your users, and wait a minute while Supabase spins up a full PostgreSQL instance, completes with an API layer, real\u2011time engine, and authentication endpoints. After the project is ready, you\u2019ll land on the dashboard. Here, locate the \u201cProject Settings\u201d -> \u201cAPI\u201d section. You\u2019ll see your <code>anon<\/code> public key and the <code>service_role<\/code> secret key (the latter should never be exposed client\u2011side). The URL (e.g., <code>https:\/\/yourproject.supabase.co<\/code>) is your API endpoint. These credentials are all you need to start interacting with your database from your frontend or backend.<\/p>\n<p>Now, let\u2019s create a simple schema. In Supabase, you can use the SQL Editor to write raw SQL \u2013 a huge advantage over Firebase\u2019s constrained console. Navigate to the \u201cSQL Editor\u201d and paste the following script to create a <code>todos<\/code> table and an <code>accounts<\/code> table (wil be useful for authentication later):<\/p>\n<pre><code>-- Create accounts table (linked to Supabase auth users)\nCREATE TABLE public.accounts (\n  id uuid NOT NULL PRIMARY KEY,\n  email text,\n  created_at timestamptz DEFAULT now(),\n  updated_at timestamptz DEFAULT now()\n);\n\n-- Create todos table\nCREATE TABLE public.todos (\n  id bigint GENERATED ALWAYS AS IDENTITY PRIMARY KEY,\n  user_id uuid NOT NULL REFERENCES public.accounts(id) ON DELETE CASCADE,\n  title text NOT NULL,\n  is_complete boolean DEFAULT false,\n  inserted_at timestamptz DEFAULT now()\n);\n\n-- Enable Row Level Security\nALTER TABLE public.todos ENABLE ROW LEVEL SECURITY;\nALTER TABLE public.accounts ENABLE ROW LEVEL SECURITY;<\/code><\/pre>\n<p>After running this, you have two tables. You\u2019ll also see that Supabase automatically created a table called <code>auth.users<\/code> where authentication records live. We\u2019ll tie our <code>accounts<\/code> table to those users via triggers (optional, but useful). For a quick test, go to the \u201cTable Editor\u201d and manually insert a couple of todos. You\u2019ll notice that the UI resembles a traditional database GUI \u2013 you can browse, filter, and edit rows. This is a massive improvement over Firebase\u2019s document view, especially when you have relational data. Now that your database and project are ready, let\u2019s move on to authentication.<\/p>\n<h2>Step 2: Implementing Authentication (Email\/Password and OAuth)<\/h2>\n<p>Supabase Authentication is built on top of GoTrue, the same underlying technology used by Netlify Identity. It supports email\/password, magic links, phone (SMS), and many social providers (Google, GitHub, Facebook, etc.) with a single API. To activate a provider, go to the dashboard -> \u201cAuthentication\u201d -> \u201cSettings\u201d and enable the \u201cEmail\u201d provider. For production, you\u2019ll configure the SMTP server to send real emails. For testing, Supabase provides a fake email service that shows confirmation codes in the dashboard logs. Next, to integrate authentication into your code, install the Supabase JavaScript client library:<\/p>\n<pre><code>npm install @supabase\/supabase-js<\/code><\/pre>\n<p>Then initialise the client with your project URL and anon key:<\/p>\n<pre><code>import { createClient } from '@supabase\/supabase-js'\nconst supabase = createClient('https:\/\/yourproject.supabase.co', 'your-anon-key')<\/code><\/pre>\n<p>Now implement a sign\u2011up form. Use <code>supabase.auth.signUp()<\/code> and store the user\u2019s email and password. After sign\u2011up, a user is created in <code>auth.users<\/code>. However, to mirror our <code>accounts<\/code> table, we need to insert a row when a new user signs up. The recommended pattern is to use a database trigger inside PostgreSQL. In the SQL Editor, run:<\/p>\n<pre><code>-- Function to copy user data to accounts\nCREATE OR REPLACE FUNCTION public.handle_new_user()\nRETURNS trigger AS $$\nBEGIN\n  INSERT INTO public.accounts (id, email, created_at, updated_at)\n  VALUES (NEW.id, NEW.email, now(), now());\n  RETURN NEW;\nEND;\n$$ LANGUAGE plpgsql SECURITY DEFINER;\n\n-- Trigger after insert on auth.users\nCREATE TRIGGER on_auth_user_created\n  AFTER INSERT ON auth.users\n  FOR EACH ROW EXECUTE FUNCTION public.handle_new_user();<\/code><\/pre>\n<p>Now every new user automatically gets a corresponding row in <code>accounts<\/code>. Logging in is equally simple: use <code>supabase.auth.signInWithPassword()<\/code>. The client automatically handles JWT management, refreshes tokens, and stores the session. For social logins, call <code>supabase.auth.signInWithOAuth({ provider: 'github' })<\/code>. Supabase will redirect the user to GitHub, then back to your app. Your app can listen to auth state changes with <code>supabase.auth.onAuthStateChanged()<\/code>. This listener fires when the user logs in, logs out, or when the token refreshes \u2013 perfect for updating your UI. One critical point: never call authentication methods with the <code>service_role<\/code> key client\u2011side. That key bypasses Row\u2011Level Security and should only be used in server\u2011side or backend contexts.<\/p>\n<h2>Step 3: Enforcing Row\u2011Level Security (RLS) with Policies<\/h2>\n<p>Supabase\u2019s security model is fundamentally different from Firebase. Firebase uses security rules written in a proprietary JSON syntax. Supabase leverages PostgreSQL\u2019s built\u2011in Row\u2011Level Security (RLS). With RLS, you write SQL policies that determine which rows a user can see, insert, update, or delete. These policies can reference the authenticated user\u2019s ID (via <code>auth.uid()<\/code>), roles, or even custom claims. Because policies are SQL, they can be extremely powerful \u2013 you can join across tables, use subqueries, and call functions. Let\u2019s create policies for our <code>todos<\/code> table to ensure users only see their own todos.<\/p>\n<p>First, make sure RLS is enabled on the table (we did that earlier). Then navigate to the \u201cAuthentication\u201d -> \u201cPolicies\u201d section in the Supabase dashboard, or write SQL directly. I prefer SQL for clarity. Run these policy statements:<\/p>\n<pre><code>-- Allow users to SELECT only their own todos\nCREATE POLICY \"Users can view their own todos\"\nON public.todos FOR SELECT\nUSING (auth.uid() = user_id);\n\n-- Allow users to INSERT todos with their own user_id\nCREATE POLICY \"Users can insert their own todos\"\nON public.todos FOR INSERT\nWITH CHECK (auth.uid() = user_id);\n\n-- Allow users to UPDATE only their own todos\nCREATE POLICY \"Users can update their own todos\"\nON public.todos FOR UPDATE\nUSING (auth.uid() = user_id);\n\n-- Allow users to DELETE only their own todos\nCREATE POLICY \"Users can delete their own todos\"\nON public.todos FOR DELETE\nUSING (auth.uid() = user_id);<\/code><\/pre>\n<p>After creating these policies, even if a malicious attacker obtains your anon key (which is public), they cannot read or modify todos belonging to other users. The database engine rejects any query that doesn\u2019t satisfy the policy. This is a huge advantage over Firebase\u2019s client\u2011side rules, which can be accidentally misconfigured. In Supabase, you can test your policies by using the \u201cRun SQL\u201d feature in the dashboard with a simulated role (use <code>set role authenticated<\/code> and <code>set request.jwt.claims...<\/code>). For our <code>accounts<\/code> table, you might want a policy that lets users only see their own account row, but other users (like admins) can see all. RLS scales effortlessly with complex roles.<\/p>\n<h2>Step 4: Performing CRUD Operations with the Supabase Client<\/h2>\n<p>Now that authentication and security are in place, let\u2019s interact with the database from your frontend. The Supabase JavaScript client offers a fluent query builder that translates to SQL under the hood. For basic CRUD, you use <code>supabase.from('todos')<\/code> followed by <code>.select()<\/code>, <code>.insert()<\/code>, <code>.update()<\/code>, or <code>.delete()<\/code>. Remember, because RLS is active, the client automatically includes the user\u2019s JWT in every request, and the database enforces the policies. Here\u2019s an example of fetching todos for the currently logged\u2011in user:<\/p>\n<pre><code>const { data: todos, error } = await supabase\n  .from('todos')\n  .select('*')\n  .order('inserted_at', { ascending: false })<\/code><\/pre>\n<p>Notice we didn\u2019t add a <code>.eq('user_id', userId)<\/code> filter \u2013 that\u2019s because the RLS policy already restricts the rows to the current user. For inserting a new todo, you don\u2019t need to specify <code>user_id<\/code> manually if you use the <code>auth.uid()<\/code> function in a default value or policy. However, a safer approach is to let the frontend send the authenticated user\u2019s ID (obtained from <code>supabase.auth.user().id<\/code>):<\/p>\n<pre><code>const user = supabase.auth.user()\nconst { error } = await supabase\n  .from('todos')\n  .insert({ title: 'Learn Supabase', user_id: user.id })<\/code><\/pre>\n<p>The client also supports complex queries: filtering by multiple columns (<code>.eq('is_complete', false)<\/code>), joins with other tables (via <code>.select('*, accounts(email)')<\/code>), and even full\u2011text search (<code>.textSearch('title', 'learn')<\/code>). For bulk operations, you can pass an array of objects to <code>.insert()<\/code> or use <code>.upsert()<\/code>. One key difference from Firebase: Supabase uses HTTP\/REST calls by default, not WebSockets, for standard queries. This means you get the reliability of REST with the flexibility of SQL. However, for real\u2011time, you can switch to subscriptions \u2013 covered next.<\/p>\n<p>It\u2019s also worth noting that Supabase provides client libraries for multiple languages: Python, Dart (Flutter), Swift, Kotlin, and more. The APIs are similar across all of them. If you\u2019re building a mobile app with Flutter, you\u2019ll use <code>supabase-query-builder<\/code> almost identically. The documentation is excellent and the community is growing fast. To give you a quick reference, here\u2019s a table summarising common CRUD methods:<\/p>\n<table>\n<thead>\n<tr>\n<th>Operation<\/th>\n<th>Method<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Select rows<\/td>\n<td><code>supabase.from('table').select('columns')<\/code><\/td>\n<td><code>supabase.from('todos').select('title, is_complete')<\/code><\/td>\n<\/tr>\n<tr>\n<td>Filter<\/td>\n<td><code>.eq(column, value)<\/code>, <code>.lt()<\/code>, etc.<\/td>\n<td><code>.eq('is_complete', false)<\/code><\/td>\n<\/tr>\n<tr>\n<td>Insert<\/td>\n<td><code>.insert(object | array)<\/code><\/td>\n<td><code>.insert({ title: 'Task' })<\/code><\/td>\n<\/tr>\n<tr>\n<td>Update<\/td>\n<td><code>.update(object).eq(column, value)<\/code><\/td>\n<td><code>.update({ title: 'New' }).eq('id', 1)<\/code><\/td>\n<\/tr>\n<tr>\n<td>Delete<\/td>\n<td><code>.delete().eq(column, value)<\/code><\/td>\n<td><code>.delete().eq('id', 1)<\/code><\/td>\n<\/tr>\n<tr>\n<td>Order<\/td>\n<td><code>.order(column, { ascending: boolean })<\/code><\/td>\n<td><code>.order('created_at', { ascending: false })<\/code><\/td>\n<\/tr>\n<tr>\n<td>Pagination<\/td>\n<td><code>.range(start, end)<\/code><\/td>\n<td><code>.range(0, 9)<\/code> \u2013 first 10 rows<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Step 5: Real\u2011Time Subscriptions (Live Queries)<\/h2>\n<p>One of Firebase\u2019s killer features is real\u2011time data synchronisation via listeners. Supabase replicates this using PostgreSQL\u2019s built\u2011in logical replication and a WebSocket layer called Realtime (an open\u2011source engine). You can subscribe to changes on any table: insert, update, delete, or even listen to a specific row. This is perfect for chat apps, collaborative editors, dashboards, or any dynamic UI. To use real\u2011time, you first need to enable replication on your table in the Supabase dashboard. Go to \u201cDatabase\u201d -> \u201cReplication\u201d and ensure your table (e.g., <code>todos<\/code>) is listed. By default, Supabase enables replication for all new tables. Then, in your client code, you can set up a subscription:<\/p>\n<pre><code>const mySubscription = supabase\n  .channel('public:todos')\n  .on('postgres_changes',\n    { event: '*', schema: 'public', table: 'todos' },\n    (payload) => {\n      console.log('Change received!', payload)\n      \/\/ Update your UI state\n    }\n  )\n  .subscribe()<\/code><\/pre>\n<p>The first argument to <code>supabase.channel<\/code> is a unique channel name \u2013 you can use any string. The <code>on('postgres_changes', ...)<\/code> listener will fire whenever a row in <code>todos<\/code> is inserted, updated, or deleted. You can filter by specific events (<code>event: 'INSERT'<\/code>) or by a specific row ID. Under the hood, Supabase uses PostgreSQL\u2019s WAL (Write\u2011Ahead Log) to capture changes and broadcasts them to all connected clients. The latency is typically under 100ms. One important consideration: real\u2011time subscriptions respect RLS policies. So if a user is not allowed to see a particular row (because the policy blocks <code>SELECT<\/code>), they will not receive the change for that row. This is a subtle but powerful security feature. If you need to listen only to changes that affect the current user, combine the subscription with a filter by <code>user_id<\/code> (though RLS already prevents seeing other rows, the payload still includes the full row \u2013 always check RLS for select).<\/p>\n<p>For performance, be careful not to create too many subscriptions. Instead of subscribing to every table, consider using a single channel with multiple filters, or use presence and broadcast features (available in Supabase Realtime client) for collaborative features beyond database changes. The Supabase JavaScript client also supports \u201cpresence\u201d (who is online) and \u201cbroadcast\u201d (send messages to other clients) \u2013 both are out\u2011of\u2011the\u2011box. Real\u2011time subscriptions are a huge reason to choose Supabase over a plain PostgreSQL backend. They give you Firebase\u2011like agility without sacrificing the relational model.<\/p>\n<h2>Step 6: File Storage (Database as a File System)<\/h2>\n<p>Firebase\u2019s Cloud Storage is a separate product integrated with Authentication. Supabase Storage is similarly integrated, built on top of S3\u2011compatible object storage (default is MinIO, but you can configure S3). You can create buckets, set public\/private access, upload files, and generate signed URLs for temporary access. The beauty is that file access permissions are governed by RLS policies \u2013 yes, you can write SQL policies for storage! Go to the Supabase dashboard -> \u201cStorage\u201d -> \u201cNew bucket\u201d. Create a bucket called <code>avatars<\/code> and set it to \u201cPublic\u201d for testing, or \u201cPrivate\u201d for secure files. For private buckets, you need to create policies. For example, to allow users to only access their own avatar files, you\u2019d write a policy that checks the file path prefix against <code>auth.uid()<\/code>.<\/p>\n<p>Uploading a file from the client is straightforward:<\/p>\n<pre><code>const { data, error } = await supabase.storage\n  .from('avatars')\n  .upload('public\/' + user.id + '\/' + fileName, file)<\/code><\/pre>\n<p>You can generate a public URL for public buckets: <code>supabase.storage.from('avatars').getPublicUrl(path)<\/code>. For private buckets, generate a signed URL with an expiration time: <code>supabase.storage.from('private-files').createSignedUrl(path, 60)<\/code> \u2013 the link will only be valid for 60 seconds. This is perfect for secure file delivery without exposing your storage keys. Storage also supports resumable uploads for large files, and you can list files in a folder. The entire storage API is RESTful and can be tested with cURL or Postman. Supabase Storage is a fully functional replacement for Firebase Storage, with the added benefit of SQL\u2011style permissions.<\/p>\n<h2>Step 7: Edge Functions (Serverless Functions)<\/h2>\n<p>The final piece of the Firebase alternative puzzle is cloud functions. Firebase Cloud Functions are Node.js functions that run on Google Cloud. Supabase Edge Functions are serverless functions written in TypeScript\/JavaScript that run on Deno Deploy (powered by Deno). They are incredibly fast to cold\u2011start (under 10ms) and can be deployed directly from the Supabase CLI. Edge Functions are ideal for tasks like webhooks, data validation, sending emails, or interacting with third\u2011party APIs. They integrate with your Supabase project via environment variables and can access your database using the <code>supabase-js<\/code> client with the <code>service_role<\/code> key (for admin operations).<\/p>\n<p>To create an Edge Function, install the Supabase CLI: <code>npm install -g supabase<\/code>. Then run <code>supabase functions new my-function<\/code>. This generates a TypeScript file with a handler that receives a request object. You can use <code>supabase-js<\/code> inside the function to read\/write the database. Deploy with <code>supabase functions deploy my-function<\/code>. Each function gets a public URL like <code>https:\/\/yourproject.supabase.co\/functions\/v1\/my-function<\/code>. You can set authentication requirements (like requiring a valid JWT) in the function handler itself. Because Edge Functions run on Deno, they support TypeScript natively, have access to the standard Web APIs, and can import modules from npm or deno.land. This makes them more modern than Firebase Cloud Functions (which are stuck on Node 18). Supabase also provides a \u201cserve\u201d command for local development, so you can test functions before deploying. With Edge Functions, you can move your backend logic out of the client and into the edge, reducing client complexity and improving security.<\/p>\n<h2>Tips and Best Practices<\/h2>\n<p>Now that you\u2019ve seen the core features, let\u2019s discuss some best practices to keep your Supabase project scalable, secure, and maintainable. First, <strong>always use Row\u2011Level Security<\/strong>. Even if your app is internal and all users are trusted, RLS acts as a safety net to prevent accidental data leaks. Write policies that are as restrictive as possible, and test them thoroughly in the dashboard\u2019s SQL runner. Second, <strong>leverage PostgreSQL indexes<\/strong> \u2013 add indexes on columns you frequently filter or sort by (e.g., <code>user_id<\/code>, <code>created_at<\/code>). Supabase doesn\u2019t create indexes automatically for every foreign key. You can create them from the SQL Editor: <code>CREATE INDEX idx_todos_user_id ON public.todos(user_id);<\/code>. This will make queries much faster as your data grows. Third, <strong>use TypeScript with Supabase<\/strong>. The official package includes type generation tools (run <code>supabase gen types typescript --linked > database.types.ts<\/code>) that generate TypeScript types from your database schema. This gives you autocomplete and compile\u2011time error checking for all your queries. Fourth, <strong>never expose the <code>service_role<\/code> key<\/strong> to the client. That key has full access to your database, bypassing RLS. Keep it in your server or Edge Functions. Fifth, <strong>monitor your database performance<\/strong> with Supabase\u2019s built\u2011in logs and the \u201cHealth\u201d section. You can see query performance, slow queries, and connection counts. If you plan to self\u2011host, set up monitoring tools like pg_stat_statements.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Q1: How does Supabase compare to Firebase in terms of pricing?<\/strong><br \/>\nA1: Supabase\u2019s free tier offers 500 MB database, 2 GB bandwidth, and 50,000 monthly active users (for auth) \u2013 quite generous compared to Firebase\u2019s Spark plan (which has limited database operations and no Cloud Functions). Paid plans start at $25\/month and are based on compute usage and storage. Firebase\u2019s Blaze plan charges per operation, which can be unpredictable. Supabase\u2019s pricing is simpler and often cheaper for moderate usage. However, for extremely high reads, Firebase\u2019s Firestore can be more cost\u2011effective due to its analytics\u2011focused pricing. Overall, Supabase is compelling for projects with relational data needs.<\/p>\n<p><strong>Q2: Can I migrate my existing Firebase project to Supabase?<\/strong><br \/>\nA2: Yes, but it requires effort. You\u2019ll need to redesign your data model from NoSQL to relational SQL. Export Firestore collections to JSON, then import them into PostgreSQL using scripts. For authentication, you cannot directly migrate passwords; users must reset them or you can use Firebase\u2019s custom token flow to generate temporary JWTs. Supabase\u2019s community has several migration guides and tools (like <code>firestore-to-supabase<\/code> on GitHub). It\u2019s not a one\u2011click migration, but the long\u2011term benefits often outweigh the cost.<\/p>\n<p><strong>Q3: Does Supabase support offline persistence like Firebase?<\/strong><br \/>\nA3: Not natively. Supabase\u2019s client doesn\u2019t come with a built\u2011in offline database. However, you can combine Supabase with local\u2011first libraries like <a href=\"https:\/\/rxdb.info\/\">RxDB<\/a> or <a href=\"https:\/\/github.com\/AppPear\/WatermelonDB\">WatermelonDB<\/a> for mobile apps. For web, you can cache data in IndexedDB or React Query\u2019s cache. Offline support is a limitation of Supabase compared to Firebase\u2019s Firestore offline mode, but it\u2019s a trade\u2011off for using a real SQL database.<\/p>\n<p><strong>Q4: How do I handle schema migrations in Supabase?<\/strong><br \/>\nA4: Since Supabase is PostgreSQL, you can use any migration tool: the built\u2011in SQL Editor, <a href=\"https:\/\/flywaydb.org\/\">Flyway<\/a>, <a href=\"https:\/\/www.prisma.io\/\">Prisma<\/a>, or <a href=\"https:\/\/github.com\/golang-migrate\/migrate\">golang\u2011migrate<\/a>. Prisma is popular because it provides a type\u2011safe ORM and can introspect existing tables. Supabase also offers a \u201cDatabase\u201d section where you can view and alter schemas via a GUI, but for team projects, version\u2011controlled migration files are essential.<\/p>\n<p><strong>Q5: Can I use Supabase with server\u2011side rendering (SSR) frameworks like Next.js or Nuxt?<\/strong><br \/>\nA5: Absolutely. Supabase\u2019s client can be used in Node.js environments. For Next.js, you can use the <code>@supabase\/supabase-js<\/code> package on the server (with <code>service_role<\/code> key for protected API routes) and on the client (with anon key). Supabase also provides a dedicated Next.js helper library (<code>@supabase\/ssr<\/code>) that handles cookie\u2011based sessions for RSC (React Server Components). Similarly, for Nuxt 3, there is the <code>@supabase\/nuxt<\/code> module. Supabase is framework\u2011agnostic and plays well with SSR.<\/p>\n<p><strong>Q6: What about Supabase and real\u2011time scalability?<\/strong><br \/>\nA6: The Realtime engine uses PostgreSQL logical replication, which scales vertically (more powerful DB instance). For very high\u2011frequency updates (thousands per second), you might need to tune PostgreSQL settings or use a dedicated Realtime server.
