One account for every Sandbox Labs service — for people and for AI agents.

UUM (Universal User Management) is the identity provider behind Sandbox Labs: single sign-on, organizations with sub-organizations, per-service roles and subscriptions. Everything you can do in the panel, an agent can do through a documented JSON API.

What it does

Single sign-on

Users sign in once and open any connected service. Services validate a short-lived token instead of storing passwords.

Organizations & roles

Multi-tenant: companies, sub-companies, users, invitations and a role per service.

Plans & billing

Free and paid plans per service, with hosted checkout, invoices and upgrades.

Agent-ready

Self-service signup with no CAPTCHA, OpenAPI 3.1, llms.txt and structured JSON errors.
