Short version: it runs the OpenAI Codex CLI natively on Android. No PC, no Termux, no proot. I built the whole thing on a phone and I can't actually write production code myself. I describe problems to Codex in plain English, review its patches, and ship.
v6.0.0 adds an Agent Chat pane that reads Codex output live (one-tap fixes), a home-screen Scouter widget with quota/cost/rate-limit gauges, and full Z Fold support (that last one was the hardest part by far).
It's open source, GPLv3: https://github.com/RYOITABASHI/S...
Shelly runs the OpenAI Codex CLI natively on Android — no PC, no Termux, no proot. It pairs a real native terminal with an Agent Chat pane that reads Codex output live and runs fixes with one tap. A home-screen Scouter widget shows quota, cost and rate limits, and lets you fire prompts straight from the home screen. Local LLMs (Qwen3.5 + llama.cpp) supported. Open source, GPLv3.
Built entirely by directing AI agents — I don't write the code myself.
