Changelog entry pages advertised a `.md` alternate tag unconditionally while the page is ISR, so an entry published in the changelog repo between www deploys pointed agents at a `.md` sibling that 404s until the next build (the static file and `CHANGELOG_PAGES` are both build-time artifacts). PR #49357 made bare-URL negotiation fail closed for those entries; I gate the advertising side here the same way. **Changed:** - **No more dead `.md` links on freshly published entries**: `getStaticProps` passes a `hasMarkdownVariant` flag computed from `CHANGELOG_PAGES` membership and the page renders the alternate tag only when true. An entry published between deploys carries no tag until the build that ships its `.md` file; the set reference stays inside `getStaticProps`, so the generated module stays out of the client bundle. - **Drift coverage**: `md-alternates.test.ts` gains the changelog direction, source-level like the existing `_app.tsx` drift test; the assertion pins the full `CHANGELOG_PAGES.has(` + backtick-`changelog/${entry.slug}`-backtick + `)` expression so a dropped key prefix fails the suite, and removing the gate fails it too. **Note:** without changelog sync secrets `CHANGELOG_PAGES` is empty, so the tag never renders in local dev. Preview and prod are the verification surface. ## To test Tested on Vercel preview: - [x] Open a published changelog entry page and view source: expect `<link rel="alternate" type="text/markdown" href="/changelog/<slug>.md">` in the head — observed exact href `/changelog/19669-supavisor-1-0.md` - [x] Fetch that href: expect 200 with `content-type: text/markdown` — observed 200, `text/markdown; charset=utf-8` - [x] (added) Client-side nav from `/changelog` into an entry: alternate tag appears with that entry's slug; hopping to a second entry updates the href (no stale tag) - [x] (added) Navigating back to `/changelog`: entry tag gone; the index shows its own pre-existing `/changelog.md` alternate (hardcoded in `pages/changelog.tsx`, outside this diff), and `/changelog.md` returns 200 `text/markdown` - [x] (added) Console: zero new errors across all scenarios vs page-load baseline ## Linear - fixes GROWTH-1120 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Changelog pages now advertise a Markdown alternate link only when a Markdown version is available. * Prevented links to unavailable Markdown content from appearing on changelog entries. * **Tests** * Added coverage to verify correct Markdown alternate detection and rendering. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

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.
