Elysia
Bun-native web framework with end-to-end type safety. Built for speed.
In plain English
Like Hono (the restaurant kitchen) but built specifically for one type of oven that's really fast. If you're already using that oven (Bun), Elysia is the kitchen designed to get the most out of it.
Real-world example
You're building a real-time chat app and need the backend to be extremely fast. Elysia handles thousands of messages per second because it's built on Bun, which is faster than the traditional Node.js runtime.
Where this fits in your project
Same role as Hono or Express — your API layer — but optimized for Bun and type safety.
When to use this
When you want the fastest possible developer experience for building APIs. Bun-native, end-to-end type safe, and the syntax is beautiful.
The situation
You're using Bun (not Node) and want a framework that feels like it was designed for it.
Good for
- + Bun projects
- + Type-safe APIs
- + Real-time apps
Not ideal for
- - Node.js projects (use Hono instead)
- - When you need Cloudflare Workers compatibility
Getting started
Run `bun create elysia app` to scaffold a new project.
