Bunflare

Bunflare v0.2.25 is a Bun bundler plugin that transforms Bun-native APIs (e.g., Bun.serve, bun:sqlite, Bun.password.hash) into Cloudflare Workers equivalents at build time. It targets developers who want Bun's DX but need to deploy to Cloudflare Workers. Key differentiators: zero runtime overhead (transform happens at build time), no code changes required for the developer, supports auto-discovery from wrangler.jsonc, and covers a wide range of Bun APIs including D1, KV, R2, Hyperdrive, WebCrypto, Workers Assets, and fullstack builds. Released as a dev dependency, it requires Bun >=1.0.0 and optionally integrates with Hono and Drizzle ORM. The package ships with TypeScript types. The project is actively maintained with recent commits.
