Build agents. Not the platform they run on.
Ship AI features without reinventing auth, multi-tenancy, sandboxing, and observability.
Challenges we hear every week.
Custom infra is a distraction
Every hour on your own agent runtime is an hour not shipping to users.
Security is hard to retrofit
Credential isolation, RBAC, audit logs — easier to inherit than to add later.
Multi-tenant is non-trivial
Getting applications + end-users + impersonation right takes months.
Five concepts. One API.
Everything multi-tenant SaaS needs to ship AI features — already modeled, already typed, already secure.
Applications
One deployment, many isolated customers. API keys scope to apps, never to orgs.
Learn more →End-users
Your users, managed via API. External identities with metadata — not dashboard users.
Learn more →Impersonation
Appstrate-User header (à la Stripe-Account). One key, N users, full audit trail.
Learn more →RBAC
78 typed permissions, security-review ready. Extend in the same PR as your feature.

TypeScript SDK
One import. Typed. Works with your existing stack.
Stripe-grade API
Date versioning, idempotency, RFC 9457 errors. Feels familiar.
