## What kind of change does this PR introduce? Bug fix. ## What is the current behavior? Fixes #48559 (diagnosed by @ayaangazali) The TanStack Start runtime never applies maintenance mode. `matchRedirect` in `apps/studio/redirects.shared.ts` takes a `maintenanceMode` flag, and both other consumers wire it from the environment: - `apps/studio/next.config.ts` — `process.env.MAINTENANCE_MODE === 'true'` - `apps/studio/vercel.ts` — same The TanStack call site in `apps/studio/routes/__root.tsx` passed only `pathname`, `search`, `isPlatform` and `hash`, so `maintenanceMode` fell back to its `= false` default. With `MAINTENANCE_MODE=true` on a TanStack deploy that produced two wrong behaviors: 1. No path redirected to `/maintenance` — the app served normally during maintenance. 2. Because the flag read false, the "not in maintenance" branch still applied and sent `/maintenance` → `/`, making `routes/maintenance.tsx` unreachable. Mainly affects self-hosted / Node-server TanStack deploys; the platform deploy is covered by the Vercel edge layer, which does wire the flag. ## What is the new behavior? The TanStack runtime honors `MAINTENANCE_MODE` the same way the Next runtime and the edge config do. **Design note.** The issue asked whether this needs a new `NEXT_PUBLIC_` variable or server-side plumbing, since both would change deployment configuration for self-hosters. Neither is needed. `MAINTENANCE_MODE` is already a *build-time* variable in both existing consumers — Next bakes `redirects()` into `routes-manifest.json` during `next build`, and `vercel.ts` reads it while emitting `vercel.json`. Toggling maintenance has always required a rebuild, never just a server restart. And `vite.config.ts` isn't bound by Next's "only `NEXT_PUBLIC_`" rule: it controls `define` directly, and already re-exposes unprefixed `VERCEL_*` vars the same way. So the existing unprefixed variable is inlined at build time, giving exact parity with **no new env var and no config change for self-hosters**. Three changes: 1. `vite.config.ts` — inline `process.env.MAINTENANCE_MODE` into the bundle. Falls back to `''` rather than being left undefined, so the browser bundle never ends up with a bare `process.env` reference (the failure mode the file already guards against for the Sentry vars). 2. `routes/__root.tsx` — read it into `IS_MAINTENANCE_MODE` and pass it to `matchRedirect`. 3. `redirects.shared.test.ts` — 4 tests for the maintenance branches of `matchRedirect`, which had no coverage at all. `turbo.jsonc` already lists `MAINTENANCE_MODE` under the build task's `env`, so cache invalidation is correct for the Vite build too — no change needed. No README or docs change either, since the env contract is unchanged. ## Additional context Verified end-to-end, not just by unit test. **Browser repro** — built SPA served via `scripts/serve.js`, driven in headless Chromium: | `MAINTENANCE_MODE=true` | lands on | | | --- | --- | --- | | `/project/default` | `/maintenance` | fixes behavior 1 | | `/` | `/maintenance` | | | `/maintenance` | `/maintenance` | fixes behavior 2 | The maintenance page renders real content ("Under Maintenance — We are currently improving our services…"), so the route is genuinely reachable. | control, var unset | lands on | | | --- | --- | --- | | `/project/default` | `/project/default` | normal routing intact | | `/` | `/project/default` | root redirect intact | | `/maintenance` | `/project/default` | correctly bounces away | **Bundle inspection** — the flag compiles to a literal `true` with the variable set and `false` without it, confirming the define reaches the client. **Shell prerender** — checked explicitly, since the maintenance-on rule is a catch-all. Builds with `MAINTENANCE_MODE=true` prerender the SPA shell and pass the post-build smoke test; the prerenderer crawls `/` and the root `beforeLoad` redirect does not fire during shell generation, so no guard is required. **Checks** — 20 unit tests pass, typecheck 8/8, ESLint ratchet passes, Prettier clean. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added maintenance-mode routing for unavailable pages. - Preserves query parameters and URL fragments during redirects. - Allows access to maintenance and image paths while maintenance mode is active. - Automatically returns visitors to the home page when maintenance mode is disabled. - Maintenance behavior is controlled by the deployment configuration. - **Tests** - Added coverage for maintenance-mode redirects, URL preservation, and exceptions. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Co-authored-by: Alaister Young <10985857+alaister@users.noreply.github.com>

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.
