How I built a browser-based video editor with FFmpeg.wasm (no backend, no server costs)

I got tired of opening CapCut every time I needed to quickly join 2-3 clips. Too many menus, too many features I'll never use. So I built my own. 2minclip.com — a free online video editor that runs entirely in the browser. No install, no signup, no watermark. Here's how I built it and what I learned.

This means: Zero server costs (users process video on their own device) Complete privacy (videos never leave the user's device) No backend to maintain ## Tech stack React + Vite — fast dev experience, easy deployment FFmpeg.wasm — video processing in the browser Tailwind CSS — styling dnd-kit — drag and drop for the timeline i18next — ES/EN internationalization Vercel — deployment (free tier covers ev
