Define schemas, validate data, and collaborate in real-time — all backed by your own database. SchemaStack gives you the tools without taking your data.
Free forever • No credit card required • Your data stays yours
Connect your database or use managed hosting — either way, your data stays yours
SchemaStack connects to your existing database and only stores metadata. Your business data never leaves your infrastructure — no vendor lock-in, ever.
Don't want to manage infrastructure? We offer Managed RDS and Enterprise ZFS hosting. Your database stays dedicated to your organization and can be migrated out anytime.
View and edit your data through a familiar interface with real-time collaboration. Create custom views with filters, sorting, and presets for every workflow.
Every workspace automatically gets a full REST API with CRUD operations, filtering, pagination, and Swagger docs. No code generation — the API is live as soon as your schema is defined.
Define entities, columns, types, and constraints. Column validation and cross-field rules catch data problems before they enter your system.
Isolated workspaces with granular permissions. Manage organizations, members, and roles — each workspace gets its own database connection and API.
