The Bridge

Auth, billing, feature flags and teams for your SaaS app.

The Bridge

The Bridge is a hosted backend for SaaS apps: sign-in (passwords, magic links, passkeys, social login and SSO), multi-tenant workspaces with roles, Stripe subscriptions with plan limits, and feature flags, all managed from one dashboard.

Add it to your app with one of the open-source SDKs below, or let your AI coding assistant set it up through the Bridge MCP server.
