## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## What kind of change does this PR introduce? This is a docs update. The shared architecture diagram and several docs pages still described Kong as Supabase's API gateway, even though the hosted platform has run Envoy since 2025. Both diagram variants are rebuilt with real, accessible text — the originals rendered every label as an outlined vector path with zero `<text>` elements — so the gateway name can be kept current going forward, and the platform-facing prose that named Kong directly is updated to Envoy. Closes DOCS-1262. ## What is the current behavior? - The architecture diagram (used on the Architecture overview, Auth architecture, Self-hosting Docker, and Contributing guide pages) shows "KONG / docs.konghq.com" as the gateway box - The Architecture overview page has a "Kong (API gateway)" component section - The Auth architecture page states "Kong API gateway. This is shared between all Supabase products." - `README.md` and `apps/docs/public/humans.txt` credit Kong instead of Envoy ## What is the new behavior? - Rebuilt `supabase-architecture.svg` and `supabase-architecture--light.svg` with real `<text>` elements; the gateway box now reads "ENVOY / envoyproxy.io" with identical layout, colors, and shadows otherwise - Updated the diagram alt text and the "Kong (API gateway)" section (now "Envoy (API gateway)", with the correct docs link, license, and language) on the Architecture overview page - Updated the "Kong API gateway" bullet and diagram alt text on the Auth architecture page - Updated the Kong credit to Envoy in `README.md` and `apps/docs/public/humans.txt` **Intentionally excluded:** - Self-hosted Docker Compose pages (`docker.mdx`, `enable-mcp.mdx`, `self-hosted-auth-keys.mdx`, `self-hosted-envoy.mdx`, `self-hosted-functions.mdx`, `self-hosted-proxy-https.mdx`) — these describe the self-hosted stack, which still defaults to Kong today and is already owned by an open PR (#48153) that flips that default - `i18n/README.*.md` (29 files) — translation risk without native-speaker review; only the English `README.md` was updated ## Open questions - [ ] #48153 merges and the self-hosted default actually flips to Envoy — once it does, revisit the self-hosting Docker Compose pages excluded from this PR and the self-hosting-analytics reference TODO - [ ] Confirm whether all legacy platform instances have fully migrated to Envoy — until then, this PR's wording says "Envoy" without claiming Kong is gone everywhere (some legacy instances may still silently be on Kong) - [ ] Current Envoy response header names confirmed for the logs guide TODO (`x-kong-proxy-latency` / `x-kong-upstream-latency`) - [ ] i18n README translations (29 files) follow up separately with native-speaker review ## Additional context - Verification: rendered both new SVGs with `rsvg-convert` and visually diffed against the originals — layout, spacing, colors, and shadows are pixel-equivalent; only the top-box label text changed | Check | Result | | --- | --- | | `rsvg-convert` render, dark variant | pass — diagram unchanged except gateway label | | `rsvg-convert` render, light variant | pass — diagram unchanged except gateway label | | Preview URL, Architecture overview | pass — 200 | | Preview URL, Auth architecture | pass — 200 | ### Before & After #### [Architecture overview](https://supabase.com/docs/guides/getting-started/architecture) | [Before (production)](https://supabase.com/docs/guides/getting-started/architecture) | [After (PR preview)](https://docs-git-nikrichers-docs-1262-architecture-docs-84e339-supabase.vercel.app/docs/guides/getting-started/architecture) | | --- | --- | |  |  | #### [Auth architecture](https://supabase.com/docs/guides/auth/architecture) | [Before (production)](https://supabase.com/docs/guides/auth/architecture) | [After (PR preview)](https://docs-git-nikrichers-docs-1262-architecture-docs-84e339-supabase.vercel.app/docs/guides/auth/architecture) | | --- | --- | |  |  | ### Test plan - [ ] Diagram renders correctly in both light and dark mode on the preview - [ ] "Envoy (API gateway)" section reads correctly on the Architecture overview page - [ ] Auth architecture bullet reads "Envoy API gateway" - [ ] The two TODO-marked follow-ups (logs guide, self-hosting-analytics) are acceptable to leave for later rather than block this PR --------- Co-authored-by: Nik Richers <nik@validmind.ai> Co-authored-by: Miranda Limonczenko <miranda.limonczenko@supabase.io>

Maintainers
If you are a maintainer of any tools in the Supabase ecosystem, you can use this site to provide documentation for the tools & libraries that you maintain.
DocSpec
We use documentation specifications which can be used to generate human-readable docs.
- OpenAPI: for documenting API endpoints.
- SDKSpec (custom to Supabase): for SDKs and client libraries.
- ConfigSpec (custom to Supabase): for configuration options.
- CLISpec (custom to Supabase): for CLI commands and usage.
The benefit of using custom specifications is that we can generate many other types from a strict schema (eg, HTML and manpages). It also means that we can switch to any documentation system we want. On this site we use Next.js, but on Supabase's official website, we use a custom React site and expose only a subset of the available API for each tool.
