Powerful Features

Everything you need for modern, enterprise-grade API development from a single schema

The Challenge

  • Repetitive code dominates database development
  • Delivering consistent APIs is difficult – especially in teams
  • Migrating legacy databases to modern APIs is slow and costly
  • Validation logic is duplicated across frontend and backend
  • Ad-hoc data questions are slow and expensive to answer
  • Permission enforcement is complex and error-prone

Our Solution

  • One schema powers your entire system
  • Server, UI, AI, and docs generated automatically
  • Validation comes from metadata—not hand-written code
  • AI turns your data into an on-demand natural-language interface
  • Metadata-driven permissions eliminate mismatched rules

Database Support

Seamless Greenfield & Brownfield

Start fresh with bespoke schema.mmd or use s2ai.import to extract schemas from existing databases. Truly seamless support for both approaches.

Brownfield: Extract from existing databases using s2ai.import
Greenfield: Write schema.mmd directly
Multiple databases backends: MongoDB, PostgreSQL, Excel, SQLite, Elasticsearch. New adapters added regularly
Brownfield: Generate s2ai server with OpenAPI spec and AI enablement from existing DBs
No vendor lock-in

Consistency

Single Source of Truth

schema.mmd is the single source of truth that drives your entire application. Changes in the schema automatically propagate to server, UI, and documentation.

One schema file controls everything
Automatic consistency across components
No drift between API and documentation
Simplified maintenance

Browser UI

Browser-based, metadata-Driven Admin UI with s2ai.face

Complete admin UI to your data.

Full featured UI with CRUD operations, data paging, filtering and sorting
Highly customizatable driven exculsively with metadata.
No manual configuration required
Instant adaptation to schema changes

Access Control

Built-in Auth Support

All components support comprehensive authentication and authorization access control. This is enforced throughout the s2ai stack using our authn/authz service or external services.
