THE FOUNDATION, ALREADY BUILT
SaaS Starter Kit.
Your product starts where
the infrastructure is ready.
A working foundation for multi-tenant B2B software. Teams, permissions, billing and APIs — connected in one carefully designed workspace.
No account. No real payments. Your own isolated sandbox. Demo data resets automatically after six hours.
Separate workspaces
Tenant isolation and team invitations.
Permissions that hold
Four roles. Authorization on the server.
Ready for the business
Plans, billing states and an audit trail.
A real integration surface
Scoped API keys and recorded usage.
BUILT TO EXTEND
The reusable work.
Before your business logic.
Relay is a fictional product demonstrating this starter. Explore the same workspace as an owner, admin, member or viewer, and see how access changes.
