AI coding tools build apps in hours. Then production breaks — data leaks across users, and access rules are unclear.
UMA is the backend for AI-built apps — handling data isolation, access control, and schema evolution, so your AI can build fast and evolve safely.
The Problem
Traditional backends weren't designed for AI-generated code. When Cursor or Claude modifies your schema, there's no safeguard against breaking existing data or rules — fields get repurposed, permissions get bypassed, data gets corrupted.
UMA gives your AI agent a machine-readable layer of what your data means — so it can evolve your app without destroying it.
How it works
Tell your AI agent what you're building. It creates a semantic data model in UMA — capturing intent, not just structure.
Cursor or Claude builds your UI. UMA handles the backend — auth, permissions, and data isolation are automatic.
As your app evolves, UMA gives AI the context it needs to make schema changes safely — so it understands what your data means before touching it.
Ship immediately. No manual migrations, no backend setup. Auth, data isolation, and permissions work out of the box — and you can configure them to fit your specific needs from the UMA portal.
Features
AI-generated schema changes often break production data silently and irreversibly.
UMA gives AI the context it needs — what your data means and how it's used — so it can update your app's structure without corrupting your existing records.
AI-generated code often exposes data incorrectly — one user can see another user's records.
UMA isolates data per user automatically. Users only ever see the data that belongs to them, regardless of what the AI generates.
Wiring auth and permissions is tedious, slows down development, and is frequently misconfigured by AI agents.
UMA provides built-in user management, JWT auth, and a two-layer Role + Permission system. AI queries it directly via API.
Database migrations are fragile, manual, and a constant source of production incidents.
UMA handles schema evolution dynamically. No migration files, no downtime, no rollback anxiety.
AI agents can't reliably infer what business rules exist or what operations are safe to perform.
UMA exposes a machine-readable API that Cursor, Claude, and other AI agents can query — so they always know what your data means and what's safe to do.
Out of the box
Every app built on UMA gets these from the start — not as add-ons, not as config files.
Control exactly who can join your app. Pick the policy that fits — no custom auth code needed.
Every user only sees their own data. No shared tables, no accidental exposure — isolation is built into the structure, not bolted on.
Two-layer Role + Permission system, AI-queryable at runtime. Your frontend renders the right UI for each user automatically.
"AI coding assistants can build a new app in minutes.
They can also destroy it just as quickly when you make changes.
UMA is the guardrail that helps prevent those mistakes."
