Best alternatives to fx in 2026
Most AI coding agents today are built like chat apps: a runtime to install, gigabytes of dependencies, and a few seconds of startup lag before you can type your first prompt. fx takes the opposite approach — it's a single native binary under 8 MB, written in the systems language Zig specifically so it can start in microseconds and run with almost no memory overhead, more like a Unix command-line tool than a chat interface. fx started as an internal tool at Vercel before being open-sourced on August 17, 2026 under the Apache-2.0 license. It's model-agnostic (works with multiple AI providers, local or cloud), supports session resumption, and extends through skills, plugins, and MCP tools rather than a fixed feature set — plus WebAssembly support for embedding it inside other software. The tradeoff for that minimalism: the project is explicitly marked experimental, with the maintainers flagging that its autonomous execution needs careful permission management, and it currently favors a narrower set of auth/provider integrations than more mature CLI agents.

theditch.dev
- ✓ Supervise plusieurs sessions Codex/projets en un seul endroit
- ✓ Local-first, pas de compte requis
#8
A Python CLI that runs your old and new code on the same inputs, diffs everything that could differ, and tells you exactly what changed behavior during a refactor or migration.
github.com
- ✓ Génération automatique d'inputs, pas besoin d'écrire des tests à la main
- ✓ Comparaison exhaustive (valeurs, exceptions, stdout, mutations)
#9
An AI coding agent for mobile apps that streams a live iOS Simulator or Android Emulator preview right into the chat, so you can watch changes render as the agent writes code.
github.com
