Elysia
Ergonomic web framework for Bun
Elysia is a TypeScript-first web framework for Bun with end-to-end type safety, Eden treaty for client generation, and exceptional performance.
Panel Reviews
The Builder
Developer Perspective
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
The Skeptic
Reality Check
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
The Futurist
Big Picture
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
Community Sentiment
“Bun + Elysia benchmarks are absurd — 3x Express performance on real workloads is hard to dismiss”
“Eden treaty for end-to-end type safety without tRPC overhead is the killer feature here”
“Elysia makes Bun feel production-ready — the ergonomics are better than Fastify and the speed is unmatched”
“The TypeScript-first DX with automatic OpenAPI generation makes this my go-to for new APIs”
