You send a task in plain language, the agent gets a fresh environment, does the work, and returns structured results plus a full action log. Every click and keystroke is recorded, so you can replay exactly what the agent did. Setup takes 2 to 5 minutes per environment, then the agent runs unattended until the task is done or it decides a human should take over. You can switch out any part of the harness and use/call whatever you need. Completely modular and transparent with the pricing at the end(Doc) for every type of call.
Docs are at Coasty/Docs. The quickstart gets you to a first running task in a few minutes. If you build something with it, tell me. I read everything in this thread.
Coasty is a computer use agent that operates real desktop software end to end. Started with healthcare prior auth, automating payer portals and legacy EHRs, and data removal for data privacy but now we're expanding into insurance and tax & accounting. Coasty does that work autonomously, with human takeover and full audit trails. Independently verified at 82.81% on OSWorld Verified (359 tasks), near the top of the leaderboard. No APIs required. If software has a screen, Coasty can run it.
