### SDK changes analyzed

| SDK | Repository | Commits | Latest Tag |
|-----|-----------|---------|------------|
| JS | supabase/supabase-js | 78 | v2.104.0-canary.0 |
| Dart | supabase/supabase-flutter | 17 | - |
| Python | supabase/supabase-py | 11 | v2.28.3 |
| Swift | supabase/supabase-swift | 13 | v2.43.0 |

| C# | supabase-community/supabase-csharp | 0 (no changes) | v1.1.2 |

### Documentation updates

**Spec files:**
- **JS** (`supabase_js_v2.yml`): Added custom OIDC/OAuth provider admin
CRUD method refs (`createProvider`, `listProviders`, `getProvider`,
`updateProvider`, `deleteProvider`)
- **Dart** (`supabase_dart_v2.yml`): Added custom OAuthProvider class
example, `accessToken` param for `setSession()`, `useNewHostname`
storage option
- **Swift** (`supabase_swift_v2.yml`): Added PostgREST automatic retries
initialization example, realtime callback registration timing note
- **Kotlin** (`supabase_kt_v3.yml`): Added streaming edge functions
(SSE) example via `collectAsFlow`, `currentPassword` param for
`updateUser`, `urlLengthLimit`/`timeout` PostgREST config options

**Guides:**
- `api/automatic-retries-in-supabase-js.mdx`: Added built-in PostgREST
retry documentation (enabled by default since v2.102.0), restructured
guide to show native retries first, `fetch-retry` as advanced option
- `auth/passwords.mdx`: Added `currentPassword` verification section
with JS and Kotlin examples

## Test plan

- [ ] Verify YAML spec files parse correctly (validated locally with
Python yaml parser)
- [ ] Check that `$ref` entries for JS custom provider admin methods
resolve correctly against tsdoc
- [ ] Review rendered documentation for all updated spec sections
- [ ] Verify MDX guide pages render correctly with new Tabs/TabPanel
sections

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.
  • GitHub Issues. Best for: bugs and errors you encounter using Supabase.
  • Email Support. Best for: problems with your database or infrastructure.
  • Discord. Best for: sharing your applications and hanging out with the community.

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.
  • Kong is a cloud-native API gateway.

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.
