What is TriFrost?
Welcome to TriFrost — your soon-to-be favorite server framework.
TriFrost isn’t just another server library; it’s a runtime-agnostic, performance-obsessed, TypeScript-first framework designed to run anywhere — Node.js, Bun, uWS, Cloudflare Workers — you name it.
🚀 Why it exists?
Because most server frameworks either:
- Lock you to a single runtime (Node-only, Bun-only)
- Come overloaded with magic you can’t trace
- Sacrifice performance for developer convenience (or vice versa)
TriFrost flips the table on that.
It gives you:
- Explicit, no-magic design: middleware, routing, context, all fully transparent
- Zero-cost abstractions: performance baked into the core, not sprinkled on later
- First-class TypeScript: powerful generics, fully typed context/state, and type-safe middleware chains
- Built-in observability: structured logs, tracing, and telemetry ready to go, no duct tape required

🌍 Where can I use it?
Pretty much anywhere modern JavaScript can run.
TriFrost is built with an adaptive core that plugs into:
- Node.js (with or without uWebSockets.js)
- Bun
- Cloudflare Workers (Workerd)
- Future runtime
This means you can write your app once, deploy it anywhere, and scale confidently.
🧠 TLDR
- Explicit middleware chaining: No hidden layers. What you write is what runs.
- Runtime adapters: Each runtime has its own optimized adapter, but the app code stays the same.
- Modern DX: JSX support, SSR-ready, native-style engine, and async-safe from top to bottom.
- Advanced typing: Context-safe generics, type-checked middleware chains, and intelligent inference.
- Advanced tooling: Built-in rate limiting, caching, authentication middleware, and more.
🥶 Stay frosty. TriFrost is the high-performance, low-bullshit framework you’ve been waiting for.
