claude[bot]andClaude 89a5d03817 docs: add eu-central-2 to Edge Functions regional invocation page (#48721)
<!-- ccr-slack-attribution -->
_Requested by **Kalleby Santos** · [Slack
thread](https://supabase.slack.com/archives/C02KMRX22NR/p1785871243937099?thread_ts=1785871243.937099&cid=C02KMRX22NR)_

## 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?

Docs update — one-line content fix.

## What is the current behavior?

The [Regional
Invocations](https://supabase.com/docs/guides/functions/regional-invocation)
page's "Available regions" section lists every Edge Functions region
**except `eu-central-2`** (AWS Europe, Zurich). The region has been live
in production for a while, but it was never added to the docs. A user
reading this page to pick a region for `x-region` / `FunctionRegion` had
no way to know Zurich was an option — the page reads as an exhaustive
list, so the omission actively implies the region doesn't exist.

Reported by Kalleby Santos (Edge Functions team).

Linear: [FUNC-761 — Add eu-central-2 to regional invocation docs
page](https://linear.app/supabase/issue/FUNC-761/add-eu-central-2-to-regional-invocation-docs-page)

## What is the new behavior?

**Before:** the Europe group listed `eu-central-1`, `eu-west-1`,
`eu-west-2`, `eu-west-3`.

**After:** `eu-central-2` (Zurich) is listed alongside the others, so
the page reflects the regions Edge Functions actually serves.

### How

One line added to
`apps/docs/content/guides/functions/regional-invocation.mdx`, in the
**Europe** group directly after `eu-central-1`, following the list's
existing sort-by-region-code order and the surrounding `` `code` (Short
location) `` label style:

```diff
 **Europe:**

 - `eu-central-1` (Frankfurt)
+- `eu-central-2` (Zurich)
 - `eu-west-1` (Ireland)
 - `eu-west-2` (London)
 - `eu-west-3` (Paris)
```

No other files changed. This page's region list is hand-maintained in
the MDX and is deliberately narrower than the project-creation region
list in `packages/shared-data/regions.ts` (which also includes
`us-east-2` and `eu-north-1`), so no shared constant needed updating and
no other product's region list was touched.

## Additional context

**Verification that `eu-central-2` is a real Edge Functions invocation
region** — confirmed in three independent places:

1. `supabase/platform` → `pulumi/edge-runtime/Pulumi.prod.yaml:533` —
`region: eu-central-2`, with `enabled: true` at `:531`. A fully
provisioned prod region (360–540 always-on tasks), not a placeholder.
Branch `develop`, HEAD `1f44167768f951c0c794313006bc2c9f9758c344`.
2. `supabase/platform` →
`pulumi/edge-runtime-next/stack-config/Pulumi.prod.aws.euc2.yaml:6` —
`aws:region: eu-central-2` under the `Edge-Functions/K8s-Prod`
environment, tagged `product: functions`.
3. `supabase/api-gateway` → `customer-router/wrangler.toml` —
`eu-central-2` is present in the `EDGE_FUNCTIONS_REGIONAL_ORIGINS` map
(`eu-central-2 = "https://eu-central-2.edge-runtime.supabase.green"`).
This is the table that resolves the `x-region` header, so regional
invocation into Zurich is genuinely routable — not just deployed.

**For a reviewer to confirm separately (intentionally not in this
diff):** production infra has 16 enabled Edge Functions regions, so
`us-east-2` (Ohio, `pulumi/edge-runtime/Pulumi.prod.yaml:507`, `enabled:
true`) is *also* missing from this page. It's excluded here because we
don't yet know whether that omission is deliberate; it's being confirmed
with the team and can be a follow-up.

  • 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.
  • 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.
