CatDoes v4 ships with Compose — an autonomous AI agent that runs on its own cloud computer to build mobile apps, websites, and internal tools from plain text descriptions. You describe what you want, Compose plans the work, writes code, runs tests, fixes its own errors, and deploys — even after you close the browser tab. Every project comes pre-wired with a full backend stack: database, authentication, storage, edge functions, and real-time events. The v4 release focuses on higher reliability and GitHub integration for developers who want to export and own their codebase. Free plans start at 25 credits; paid plans begin at $20/month with more projects and higher cloud limits. What distinguishes CatDoes from the crowded AI app builder space is the "own computer" framing. The agent doesn't just generate code for you to paste — it has an execution environment where it can actually run and debug the app, catching errors before you see them. Whether that closed-loop debugging holds up in practice for complex apps is the open question.

Oh My codeX (OMX)
Hooks, agent teams, and persistent state for the OpenAI Codex CLI

Oh My codeX (OMX) is an orchestration layer that sits on top of OpenAI's Codex CLI and adds the features that Codex itself left out: lifecycle hooks, multi-agent team coordination, persistent project state, and a headless display framework. Think of it as oh-my-zsh, but for your Codex agent runtime. The project's core innovation is its team runtime: running 'omx team 3:executor "refactor auth to OAuth"' spawns three parallel agents, each working in an isolated git worktree to avoid merge conflicts. Since v0.13.1, worktree isolation is on by default. OMX also ships 33 specialist agent prompts and 36 workflow skills out of the box — including deep interview, planning, and code review flows — plus a '.omx/' directory that persists project state between sessions. Built by Yeachan Heo and hitting 26.9k GitHub stars, OMX is MIT licensed and installable in seconds: 'npm install -g @openai/codex oh-my-codex && omx --madmax --high'. It requires tmux on macOS/Linux for team features. The project has become the de-facto community layer for serious Codex power users who want more than a raw CLI.
Reviewer scorecard
“The closed-loop debugging is the real differentiator. Most AI code generators dump code on you and walk away — Compose actually runs the result and iterates. At $20/month with code export and GitHub sync, it's a serious prototyping accelerator even for experienced devs who just want to skip the boilerplate.”
“Parallel agents in isolated git worktrees is the feature every Codex power user has been waiting for — no more merge conflict hell when you run multi-step tasks. The 36 built-in workflow skills mean you're not starting from scratch. Install this the moment you start using Codex CLI seriously.”
“Every AI app builder claims autonomous error-fixing, and in practice they all hit the same wall: anything beyond CRUD starts failing in unpredictable ways. CatDoes is also a relatively unknown indie — if they fold or pivot, you're left with a codebase that was built in their proprietary stack. Export and own is a good safety valve, but validate it before depending on it.”
“Twenty-six thousand stars in three weeks is exciting but also a yellow flag — trending repos get abandoned fast, and this is a one-person project with a single maintainer. Also, tmux as a hard dependency for team features is going to break in CI/CD and containerized environments. Wait for v1.0 stability before putting this in a real workflow.”
“This is the trajectory: agents that don't just write code but execute, test, and observe it running. When the agent can monitor its own output in production and self-correct, we've crossed into genuinely autonomous software development. CatDoes is an early bet on that future at an indie scale.”
“OMX is the community layer that turns Codex from a demo into a development runtime. The pattern of community-owned orchestration shells layered on top of AI CLIs is going to become standard — and the projects that nail the UX now will define what 'agentic coding' means for the next cohort of developers.”
“As a designer who occasionally needs a working prototype but doesn't want to learn Swift or React Native, this is a gift. Being able to describe an app in natural language and get something testable on a real device within an hour is exactly the kind of tool that removes the 'I need a developer' blocker from creative projects.”
“The concept of skills-as-folders with a SKILL.md metadata file is an elegant design pattern that any non-developer can understand and remix. This lowers the bar for customizing your agent runtime without writing framework code — that's a meaningful UX step forward for AI tooling.”
