Supabase vs Stackap
Supabase is a hosted backend built around Postgres, with sign-in, storage and realtime; Stackap gives each project its own Postgres and storage on a server you own, but not sign-in or realtime.
The short answer
If you came to Supabase for a Postgres database with a generated API and file storage, Stackap offers the same shape on your own hardware. If you came for sign-in, row-level policies tied to users, or realtime subscriptions, Stackap does not have them yet, and that settles the question for those apps.
This comparison is narrower than the Vercel one, because Supabase and Stackap overlap only on the data side. Stackap also deploys the application, which Supabase does not.
On the data side the overlap is built from the same open-source parts. The generated REST API is served by PostgREST, which is the component the hosted product's own API is also built on, and file storage uses the open-source storage service pointed at an R2 bucket. That is why a real app's data calls kept working when its tables were copied across, and also why the gaps are exactly the hosted product's own extras: the pieces around the database, not the database itself.
Side by side
| Supabase | Stackap | |
|---|---|---|
| Postgres database | Yes, hosted | Yes, one private database and role per project |
| Generated REST API | Yes | Yes, a Supabase-compatible data API per project |
| Sign-in and user management | Yes | Not included |
| Realtime subscriptions | Yes | Not included |
| File storage | Yes | Yes, using the open-source storage service on R2 |
| Serverless functions | Yes | Not included |
| Hosts your application | No | Yes, with git deploys |
| Backups | Provided by the service | Daily, encrypted, restore-verified, to your own bucket |
| Browse and edit tables | Yes, in a dashboard | Yes, a table browser per project |
| Who runs it | Supabase | You |
Choose Supabase if
- Your app uses its sign-in service or realtime features.
- You want a managed database with point-in-time recovery and a team that operates it.
- You prefer not to carry operational responsibility for data.
Choose Stackap if
- Your app uses Postgres and the data API but brings its own authentication.
- You want the database, the files and the application on one server with one backup system.
- You want to own the encryption key and the backup bucket.
What the money looks like
Supabase prices by plan and usage; check its pricing page for the current figures. On Stackap the database costs whatever room it takes on a server you already pay for.
The data-side saving is real but smaller than the hosting saving, because a database is cheap to run and expensive to be responsible for. That responsibility moves to you, with daily backups and no point-in-time recovery yet.
Early-access scope
- No sign-in, no realtime, no serverless functions.
- Not every function, trigger and view in a database moves automatically; the migration tool copies tables and rows, so database functions must be carried over separately.
- Daily backups with no point-in-time recovery. A restore can lose up to a day.
- Compatibility with the data API client library has been tested on a real app's tables, not on every feature of the library.
