## Documentation

# Formbricks 5

The survey and feedback platform, self-hosted, with the two services it refuses to
start without.

## What this fixes

The existing Formbricks template pulls `formbricks/formbricks:latest` **from
Docker Hub** — where the newest tag is 3.6.0, from March 2025. The project moved
to GHCR and never published to Hub again, so that template has been deploying a
sixteen-month-old build and will never update on its own.

Bringing it current is not a tag change. Formbricks 5 refuses to boot without a
Hub and a Cube service: its environment validation fails on `CUBEJS_API_URL`,
`CUBEJS_API_SECRET`, `HUB_API_URL` and `HUB_API_KEY` before the application
starts. Upstream runs those with one-shot migration containers and
`condition: service_completed_successfully`, which a template cannot express.

## How it is expressed here

- **Hub's migrations moved into its start command.** `goose … up && river
  migrate-up … && exec /app/hub-api` — "migrate, then serve" is an ordering
  inside one service, so no separate migration container is needed.
- **Cube's configuration is baked into an image.** Upstream bind-mounts
  `cube.js` and the data model from its repository; there is no host directory
  to mount from here, so they live in `ak40u/formbricks-cube-railway` instead.
- **Hub gets its own database.** Sharing one meant Hub migrated first and the
  Formbricks Prisma migration then sat on a lock until it timed out at 300
  seconds. Upstream supports `HUB_DATABASE_URL` for exactly this.
- **Both databases are pgvector images.** Hub's first migration runs
  `CREATE EXTENSION vector`, and plain Postgres answers "extension is not
  available".

## Verified

Deployed from this template: `/health` returns 200, the sign-up page is served,
and the management API answers unauthenticated calls with `not_authenticated`
rather than a 404. The environment validation that blocks a misconfigured
Formbricks 5 passes — which is only possible if Hub and Cube are both reachable
and their secrets match.

Creating the first account happens in the browser and was not driven here.

## Services

Formbricks, its Postgres, Valkey, Hub, Hub's Postgres, and Cube. Six, because that
is what Formbricks 5 needs.

## Configuration

Nothing to fill in. Every secret and both database passwords are generated.

Formbricks is by Formbricks GmbH; the parts used here are AGPL-3.0.
