Bezzie

Bezzie is a BFF (Backend for Frontend) OAuth 2.0 authentication library for Cloudflare Workers, currently at v1.0.1 (April 2026). It implements BCP212 (OAuth for Browser-Based Apps) by keeping tokens server-side in Cloudflare KV and issuing session cookies to the frontend, preventing JWTs from ever reaching the browser. It integrates seamlessly with Hono (v4) and supports providers like Auth0, Google, and generic OIDC. Compared to alternatives (Duende BFF, @auth0/nextjs-auth0), Bezzie is framework-agnostic, runs on Cloudflare Workers' edge, and is TypeScript-first with ESM-only distribution. Active development with recent breaking changes in v1.0.0.
