Tools for the
agentic developer.
Side projects by Douwe Bos. I build software for engineers who let AI agents do the typing — and want a great seat to watch the work get done.
Desktop app
Argus
An agentic IDE for mobile and web development.
Orchestrate a flock of Claude Code agents in parallel — each in its own isolated git worktree — with live iOS simulators, Android emulators, an embedded Chromium browser, and a full VS Code editor.
- Parallel sessions, one per idea
- Live simulator + emulator mirroring
- First-class git workflow built in
CLI tool
Conductor
Let your coding agent see and drive the app it's building.
A token-efficient CLI that gives AI agents hands and eyes on a running app. Tap, type, inspect, screenshot and run flows — on iOS, Android, TV, macOS and the web — straight from an agent session.
- One CLI for every screen you ship to
- Bundles its own native drivers — no setup
- Several agents on several devices, at once
Desktop app
Grove
A native Git client for the repos your agents work in.
A fast SwiftUI Git client for macOS. Worktrees nest under the repository they came from, history keeps up with monorepos, and pull requests live in the same window.
- Worktree-aware, switch with a double-click
- Squash and interactive rebase, all undoable
- GitHub, GitLab, Bitbucket and Azure DevOps
Desktop app
Coming soonCharon
See where your disk space goes. Then get it back.
A native macOS disk analyzer that finds what's filling your Mac, cleans what apps rebuild on their own, and moves heavy folders to an external drive without breaking a path.
- Map and Rings views of any disk or folder
- Safe cleanup, everything goes to the Trash
- Move folders off your Mac, apps still find them
Desktop app
Coming soonHermes
A shelf at the edge of your screen.
Start dragging a file, some text, a link or an image and a shelf slides in. Drop it there, switch apps or Spaces, and drag it back out wherever it needs to go.
- Stacks for things dropped together
- Quick Look, share and clipboard history
- Free and open source
Desktop app
Coming soonMosaic
Window management that knows your desk.
Snap windows by dragging or with a shortcut, and save arrangements of where every app goes. Plug into your dock and each app moves to its display and spot.
- Halves, quarters and thirds, across displays
- Arrangements apply when your monitors connect
- Free and open source
