About the startup
fx is Vercel's tiny, open-source coding agent built to get out of your way. Written in Zig and shipped as a ~6MB native binary, it starts almost instantly while keeping memory and context overhead low. Use it with local or cloud models, extend it with skills, plugins and MCPs, or embed it into your own agent infrastructure. Small by design, so the model gets more room to work.
