Complex work. Coordinated.

Build the workflow.
Let agents run it.

Turn a complex build into coordinated work: a main agent, parallel implementation workers, and an adversarial test-and-review loop. Assign harnesses and models to each role. You decide what ships.

Your agents. Your subscriptions.

Local backbone

Keep the work moving.

A Rust daemon owns terminal sessions and workspace state. The Electron desktop is a view, not the lifetime of your work.

Bring your harness

Bring the vendors you already pay for.

Keep Claude Code, Codex, Pi, or Agy. Delegate across configured harnesses and use each provider through your own account. Choose approved runtimes and a fallback for each workflow.

Inspectable by default

Build. Verify. Fix. Repeat.

Let adversarial tests challenge the work, return findings for correction, and repeat within your review limit. Inspect runtime attempts and verdicts before you make the final call. MIT-licensed, with tests and reproducible build instructions.

Make room for the work

Drogon for macOS · Apple Silicon, macOS Sonoma (14)+ · v0.1.0-rc.7

Early preview, not a stable release. Release builds are Developer ID signed and notarized; versions older than v0.1.0-rc.3 were ad-hoc signed and may need Open Anyway once in System Settings → Privacy & Security. Sonoma is the supported floor for this Apple Silicon cask; the bundle's technical minimum is macOS 13 (Ventura), inherited from Electron. Use a dedicated development profile and review the installation notes before running.
