Better Auth
Open-source TypeScript authentication framework that runs in your own codebase, with optional managed infrastructure for dashboards and audit logs.
- auth
- Yes
- $20/month for Pro on the managed infrastructure. The framework itself costs nothing — the plan buys a dashboard, audit logs and security detections around it.
- Not documented
Who it suits.
Teams that want the user table in their own database and no per-user bill at all — the framework is free, and the $20 plan buys tooling rather than access.
Consider something else if…
You want a hosted service with an SLA rather than a library you run, since everything below the dashboard is your operational problem.
