SchemaStackFrom schema to collaboration — on your database

Define, validate, and collaborate on structured data — backed by your own Postgres or MySQL. Your data stays yours.

🏠

Your Data, Your Database

Customer data lives in your own Postgres or MySQL. We only store metadata. Disconnect anytime — there's nothing to export, your data is already home.

📐

Define your data structure with typed columns, constraints, and validation rules. Your schema is the single source of truth.

🤝

See changes from your team as they happen. Server-sent events keep everyone in sync without refreshing.

✅

Column and entity constraints ensure data quality before it enters your system. No more garbage in, garbage out.

🔍

Create filtered, sorted views of your data. Save them as presets and share with your team.

⚙️

Everything you can do in the UI is available through the REST API. Query data, manage schemas, and listen to real-time events.
