orca
Orca is a cross-platform desktop app (macOS, Windows, Linux) that runs several CLI coding agents side by side, each in its own isolated git worktree. It bundles terminals with splits, an editor, an embedded Chromium browser, GitHub and Linear task views, and diff annotation. A mobile companion app and an `orca` CLI let you monitor and script agent workflows.
Who it is for: Developers running several CLI coding agents in parallel on one repo
Strengths
- Works with any agent that runs in a terminal, including Claude Code, Codex, OpenCode, Pi
- Each agent gets its own git worktree; fan one prompt across several and compare
- Agents can run on a remote machine over SSH with port forwarding
- MIT license; desktop builds for macOS, Windows, Linux plus Homebrew and AUR packages
Weaknesses
- No Docker or self-hosted server install; it is a desktop app
- Mobile pairing relay lives in a separate pnpm workspace under cloud/
- Collects anonymous usage telemetry; opt-out is documented but not the default
- Ships daily and the README says its feature list lags behind
- no GPU
- Needs git, CLI coding agent of your choice
codex
Codex CLI is a coding agent from OpenAI that runs in the terminal on your machine. It installs through a shell script, npm, Homebrew, or prebuilt release binaries for macOS and Linux, and it signs in with a ChatGPT plan or an API key. The same project also covers IDE extensions and a desktop app.
Who it is for: Developers who want a terminal coding agent tied to OpenAI
Strengths
- Prebuilt binaries for macOS and Linux on x86_64 and arm64
- Multiple install paths: script, npm, Homebrew, or release archive
- Sign-in with an existing ChatGPT Plus, Pro, Business, Edu, or Enterprise plan
- Apache-2.0 license, written in Rust
Weaknesses
- README documents only OpenAI sign-in or API key; other model providers are not mentioned
- API key use requires extra setup beyond the quickstart
- RAM and disk requirements are unknown
- Install scripts fetch from OpenAI-hosted release URLs by default
- no GPU
- Needs ChatGPT account or OpenAI API key
- Models: OpenAI models
