CLI coding agent fx update: 6MB binary, WASM support, instant startup
evilrabbit_ · x · 2026-08-21
Open-source project fx (v0.0.5) has been updated, focusing on a lightweight, high-performance local CLI coding agent. Written in Zig, its binary size is approximately 6MB—small enough to fit on two floppy disks—with a cold start time of just 10µs and minimal memory footprint. The project supports WASM builds for direct browser execution while maintaining a Unix Shell-like interaction experience. fx emphasizes embeddability, making it suitable for resource-constrained environments and agent sandboxes.
