## Problem These findings came from a technical audit and verification of the claims in the doc. I found two accuracy problems: - **The guide said `getClaims()` is safe to trust** because it "validates the JWT signature against the project's published public keys every time". That only describes projects on asymmetric signing keys. With a symmetric secret it calls the Auth server instead, which the page's own partial already said. The advanced guide then read as a flat contradiction: `getUser()` was "the only way" to know a session is valid. The real distinction is revocation, not verification. - **Running the Express sample verbatim doesn't work.** In the docs sandbox, it printed `SUPABASE_URL = undefined`, so `createServerClient` received undefined for both the URL and the key. The env var tab installed dotenv twice, once inline and once through the package manager tabs, and its "And initialize it" lead-in was followed by the second install rather than any initialization. The route sample then required dotenv without calling `config()`. ## Solution - Say what `getClaims()` verifies against in each signing key mode. - Reframe the advanced guide's `getUser()` answer around session revocation, so the two pages stop contradicting each other. - Switch the advanced guide's two middleware snippets from `getUser()` to `getClaims()`, matching the guide. - Rename its `Next.js middleware` heading and CloudFront bullet, which the proxy rename missed. - Load dotenv on the first line of the Express entry point, and drop the duplicate install. - Tag both Express fences `js`. They are CommonJS, not TypeScript. - Update the stale "middleware refreshing user sessions" comment in the rendered Next.js `server.ts` sample. ## Manual testing 1. Open the [SSR client guide](https://docs-git-docs-ssr-client-accuracy-supabase.vercel.app/docs/guides/auth/server-side/creating-a-client) on the deploy preview, then the Express tab. dotenv is installed once, followed by `require('dotenv').config()`. 2. Open the [advanced guide](https://docs-git-docs-ssr-client-accuracy-supabase.vercel.app/docs/guides/auth/server-side/advanced-guide). The Next.js heading reads `Next.js proxy` and both snippets call `getClaims()`.

How it works
Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.
Architecture
Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.
- Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
- Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
- PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
- GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
- Storage a RESTful API for managing files in S3, with Postgres handling permissions.
- pg_graphql a PostgreSQL extension that exposes a GraphQL API.
- postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
- Envoy is a cloud-native, high-performance edge and service proxy.
Client libraries
Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
