Built a free, open-source Mac native swift AI agent Harness with actually usable computer use because we shouldn't need outrageous paid plans.

They were also outrageously expensive, so I built Pennant. It's free and open source. Features Runs jobs on a schedule ending in a report. Can actually Uses your Mac, sees the screen, clicks and types in your apps, and lets go the moment you touch the mouse. Publishing, sending email, With an approval card. This is enforced by the app. Not just the prompt Memory that says where it learned each thing Coding that can run on a separate agent like Claude Code or its own engine, opening pull requests as its own identity. An iPhone app for approvals and a live view of your Mac. Can use Ollama, LM Studio, vLLM, any OpenAI-compatible endpoint. With a local model it costs nothing to run and nothing leaves your Mac. No account, no telemetry. Full disclosure, it's a beta preview, Mac only (macOS 15+). Computer use needs a vision model, and long runs go better with a strong one. The iPhone app isn't on the App Store yet but you can build it from source.
