Coderblock AI
Design your database by describing your data
An AI database builder turns a plain-language description of your data into a real database: tables, relations, indexes and access rules. On Coderblock you describe entities in product terms, like members, courts and bookings, and the agent writes the Postgres schema as versioned SQL migrations on a Supabase project dedicated to your app, with row-level security protecting every table.
How does a description become a schema?
The agent extracts the entities, their fields and their relationships from what your app must do, then writes migrations that create them in Postgres. It handles the decisions people get wrong on their first schema: foreign keys, sensible types, timestamps and ownership columns that make security rules possible.
Who can read and write the data?
Exactly who you say. Access is enforced with Postgres row-level security policies generated per table: for example, users edit their own bookings, admins see all of them. Because the rules live in the database rather than only in app code, they hold even if a client misbehaves.
How does the schema evolve as the app grows?
By migration, not by rebuild. When you ask for a new feature, the agent adds migrations on top of the existing schema, preserving the data already in your tables. You can inspect the database structure anytime from the editor's backend view and request changes in plain language.
| Engine | Postgres, on a Supabase project dedicated to your app |
|---|---|
| Schema definition | Versioned SQL migrations written by the agent |
| Security | Row-level security policies per table |
| Auth integration | Supabase Auth users wired into ownership rules |
| Files | Supabase Storage for uploads alongside the database |
| Evolution | Additive migrations preserve existing data |
FAQ
- What is an AI database builder?
- It is a tool that designs and creates a database from a natural-language description of your data, producing real tables, relations and access rules instead of a diagram you still have to implement.
- Do I need to know SQL?
- No. You describe your data and rules in plain language and the agent writes the SQL migrations and policies. The generated SQL remains visible if you or a developer want to review it.
- Is my app's database shared with other Coderblock users?
- No. Each consumer app gets its own dedicated Supabase project, so your Postgres database, auth users and files are isolated from every other app on the platform.
- Can I change the schema after the app has data?
- Yes. Changes are applied as new migrations on the existing schema, so tables evolve in place and the data your users have already created is preserved.
