Pamela ChiaandAleksi Immonen 35531ea2f4 feat(www): serve openapi spec at /openapi.json (#49587)
Agent-readiness scanners and agent fetchers look for an OpenAPI spec at
conventional same-origin paths, but the Management API spec is only
served on api.supabase.com and linked from the /.well-known/api-catalog
linkset, which scanners do not read. I added a rewrite so
supabase.com/openapi.json proxies the spec from its source of truth at
api.supabase.com/api/v1-json, using the same fall-through proxy
mechanism as /humans.txt and /evals.

**Note:** no cache or CORS headers on purpose: no consumer needs them
today, and the upstream response's set-cookie header defeats edge
caching regardless. I rejected a checked-in copy of the spec in favor of
proxying live (staleness). The /.well-known/api-catalog linkset already
points at the spec (PR #44880) and is untouched here; this PR only adds
the conventional same-origin path.

**Merge order:** merge only after supabase/platform#37571 deploys. The
spec currently ships `servers: []`, so OpenAPI consumers resolve
relative paths against the fetch origin; without the platform fix this
proxy would point spec-compliant clients at supabase.com/v1/*.

## To test
Tested on Vercel preview:
- [x] `curl -s https://<preview-url>/openapi.json | head -c 40` returns
`{"openapi":"3.0.0"`
- [x] `curl -sI https://<preview-url>/openapi.json` returns 200 with
`content-type: application/json`
- [x] `curl -sI https://<preview-url>/humans.txt` returns 200 (control:
rewrite fall-through chain intact)

## Linear
- fixes GROWTH-1138

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.

Architecture

  • 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.
