Feather - Build server-rendered apps with modern simplicity.
Feather is an AI-native full-stack Python framework built for Claude Code. Combine Flask, Tailwind CSS, HTMX, and vanilla JavaScript islands for production-ready apps without SPA complexity.
Stop wrestling with hydration mismatches, "use client" confusion, and JavaScript build tooling. Start with server-rendered templates, add HTMX for interactivity, and sprinkle in JS islands only where you truly need them.
