PrinceJS

Minimal Bun framework with Scalar docs, built by a 13yo

What it does

PrinceJS is an ultra-minimal Bun web framework at 4.4kB gzipped with top-3 benchmark performance, as fast as hono, smaller than Elysia. It ships with built-in OpenAPI 3.0 spec generation, a Scalar API docs UI, Zod validation that auto-wires to routes, JWT auth, WebSockets, SSE, sessions, compression, a type-safe client, and deploy adapters for Vercel, Cloudflare Workers, Deno and Node. Built by a 13-year-old Nigerian developer.

Hey HN, I'm 13, from Nigeria, and I just released PrinceJS — the fastest web framework for Bun right now. • 19,200 req/s (beats Hono/Elysia/Express) • 2.8 kB gzipped • Tree-shakable (cache, AI, email, cron, SSE, queue, test, static...) • Zero deps. Zero config. Built in < 1 week. No team. Just me and Bun. Try it: `bun add princejs` GitHub: https://github.com/MatthewTheCoder1218/princejs Docs: https://princejs.vercel.app Brutal feedback welcome.

µJS, a 5KB alternative to Htmx and Turbo with zero dependenciesMar 2026 · mujs.org · ▲161
I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo. It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single tag, one call to `mu.init()`. No build step, no dependencies. Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element. At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.…
