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
Give Claude hands. Let it drive your app.
A token-efficient CLI for mobile and web UI testing, designed for AI agents. Tap, type, scroll, inspect, and assert — across iOS simulators, Android emulators, and browsers — straight from a Claude Code session.
- Drop-in for AI coding agents
- Bundles its own native drivers — no setup
- Multi-device parallel testing
Desktop app
Conductor Studio
Agentic QA, on the same rails.
A Maestro workbench on top of the Conductor CLI. Write flows by hand or hand them to an agent, run them against a live device, and track what they cover as test cases.
- Flow tree, editor, live device
- Agents write and repair the tests
- Same CLI your coding agent drives
