SimplerAuth (simplerauth.com) is a collection of minimal, copy-pasteable OAuth authentication libraries for Cloudflare Workers, developed by Jan_Wilmake. The project reflects Jan's philosophy that most auth frameworks are over-engineered and that a simple 200-line file is often all you need.
Jan's rationale:
"Most auth frameworks are just making things more bloated. We need something simpler."
The core insight: auth libraries create huge dependencies and abstract away auth completely. SimplerAuth takes the opposite approach — each provider is a single, highly readable, copy-pasteable file of approximately 200 lines, with no external dependencies. "There's not even a need for it to become a dependency really — it's just one copy-pasteable file."
SimplerAuth is explicitly Cloudflare Workers-only.
The project is organised as a GitHub repository (github.com/janwilmake/simplerauth) containing individual provider implementations:
withSimplerAuth middlewarex.simplerauth.comThe withSimplerAuth pattern composes cleanly with other Cloudflare Workers middleware:
withPathKv(withSimplerAuth(withStripeflare(handler)))| Date | Milestone |
|---|---|
| June 2025 | Domain purchased; initial concept |
| August 2025 | simplerauth-provider published |
| December 2025 | All templates consolidated into a single repo |
| February 2026 | SMS (Twilio) OAuth provider added |
On December 24, 2025, Jan consolidated all SimplerAuth templates into a single repository. Previously the project was distributed across a GitHub Stars list, which slowed adoption. Jan credited Sam Goodwin with suggesting the consolidation.
SimplerAuth became the auth layer for multiple Jan projects including uithub, ContextArea, and other Cloudflare Workers-based tools.
