Nothing to fill in. Every secret and both database passwords are generated. ## About Hosting Formbricks 5 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 Docker Hub again, so that template keeps deploying a build from March 2025 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 services with one-shot migration containers and `condition: service_completed_successfully`, which a template cannot express. The implementation details below are how it is expressed here instead. That makes six services: Formbricks, its Postgres, Valkey, the Hub, the Hub's Postgres, and Cube. Six, because that is what Formbricks 5 needs to start. ## Common Use Cases - **Surveys and feedback collection on your own infrastructure**, with responses stored in your own Postgres. - **Running a current Formbricks 5 build from GHCR** instead of the Docker Hub image frozen at 3.6.0. ## Dependencies for Formbricks 5 Hosting ### Deployment Dependencies - Formbricks `ghcr.io/formbricks/formbricks:5.2.1` (public) - Hub `ghcr.io/formbricks/hub:0.8.4` - Cube, built from [ak40u/formbricks-cube-railway](https://github.com/ak40u/formbricks-cube-railway) - Postgres `pgvector/pgvector:pg18`, for Formbricks - HubPostgres `pgvector/pgvector:pg18`, for the Hub - Valkey `valkey/valkey:8.1.4-alpine` Formbricks is by Formbricks GmbH; the parts used here are AGPL-3.0. ### Implementation Details - **The 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. - **The Hub gets its own database.** Sharing one meant the 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.** The Hub's first migration runs `CREATE EXTENSION vector`, and plain Postgres answers "extension is not available". ### Verification 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 the Hub and Cube are both reachable and their secrets match. Creating the first account happens in the browser and was not driven during testing. ## Why Deploy Formbricks 5 on Railway? Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.
