Felan
An open-source coding agent built to cut what you spend on models
Emerged finds new products worth a look, daily — what’s new today
It packs a model-agnostic coding agent into a ~6MB native binary that starts in microseconds, so you can embed one where a heavy IDE-style agent will not fit.
fx is a minimal, open-source coding agent from Vercel Labs, written in Zig and shipped as a native binary of about 6MB. It favours a Unix shell-like command line over a heavy terminal UI, with a ten-microsecond cold start. It is model and provider agnostic, working with Vercel AI Gateway, OpenAI Codex and xAI Grok, and is extensible through MCP, skills and subagents. A permission system governs what it can do, and WebAssembly and native builds let it run as a CLI or embed in a larger system. It is for developers wanting a lightweight, embeddable agent. Apache-2.0, experimental at v0.0.8.
