Everything a SaaS needs, already wired
Six production systems, integrated and tested — not a pile of disconnected starters.
Auth & workspaces
Email and Google sign-in with verified onboarding. Every account gets its own workspace, isolated by row-level security.
SupabaseBilling & subscriptions
Checkout, customer portal, and plan derivation handled end to end. Webhooks stay idempotent so subscription state never corrupts.
StripeTeams & invitations
Invite teammates by email with single-use tokens and role management. Transactional emails are typed React components.
ResendAdmin & impersonation
A full admin console with metrics, audited plan overrides, and read-observational impersonation. Every action is logged.
RLSRate limiting
Sliding-window limits guard every auth, billing, and admin surface. Edge-compatible and serverless-friendly out of the box.
UpstashError tracking
Webhook and API failures report to Sentry while returning safe responses. You find out before your customers do.

Built by people who ship
“We deleted three weeks of boilerplate. Auth, billing, and the admin panel were already done and actually tested — we shipped our MVP the same week.”
“The Stripe webhook handling alone saved us from a billing data mess. Idempotency and plan derivation were handled exactly the way I would have built them.”
“Row-level security from day one meant I never had to retrofit tenant isolation. The impersonation tooling made support debugging trivial.”
