Hey Automation subreddit, I’m one of the people building Coasty.
We kept running into workflows where the only way to automate them was through screenshots, mouse, and keyboard because the underlying software had no usable API and ever CUA solution was end to end.
So we built a fully modular computer-use API. You can run the full agent end to end, or use individual parts like grounding, action execution, verification, recovery, and logging inside your own automation stack while having the option to make the rest of the workflow deterministic.
We’ve been testing it on older desktop software, payer portals, and internal tools where normal scripts tend to break and have seen success so far.
I’m mainly looking for technically ugly workflows that expose where it fails.
I kept running into workflows where the software had no usable API, so we built one that works through the screen instead.
You send it a task and a machine. It uses screenshots, mouse and keyboard, recovers when something unexpected appears, and returns the full run with every action and screenshot.
The API is modular, so you can use the full agent end to end or plug in only the pieces you need, like grounding, action execution, verification, recovery, or run logging.
We just opened the developer API and need feedback. I’d genuinely like to see what breaks, especially on weird internal tools and older software.
