I built a desktop app where the AI agent can see your running app, not just your code

A developer has launched Piye, a desktop app for Mac and Linux that combines a visual app builder with a from-scratch code editor whose AI agent receives live runtime signals—terminal errors, breakpoints, simulator crashes and dead dev servers—rather than only reading project files. In one test, the agent traced two causes of a performance bug in Piye's own code in 12 minutes for roughly €2 of AI usage, and commits, pushes and deploys require explicit user approval. The app is free with 750 starting credits, and a Handoff feature generates a private GitHub repo, branch and HANDOFF.md briefing so non-developers can pass projects to engineers without lock-in.

Piye is live on Mac and Linux. One project. Build it visually, or write the code.

After more than a year of building, Piye is live on Mac and Linux.

Piye is one desktop app where you build software visually or write the code, on the same project. This post is about the code side, because that's where most of the hard work went.

AI agents read your files, but they can't see what's actually happening: the error in the terminal, the breakpoint you hit, the crash on the phone simulator, the dev server that died. So they guess, explore the project again and again, and burn tokens doing it.

Piye Code is a full code editor, built from scratch rather than forked from another editor. Its own tools report to the agent:

Because the agent gets these reports directly, it spends less time searching and more time fixing the real problem. In one of our tests, it found the two causes of a performance bug in Piye's own code in 12 minutes, for about €2 of AI.

The agent never acts behind your back: commits, pushes and deploys each need your explicit approval.

On Piye's own credits, code work is charged at the AI's cost, so you're not paying a markup to write code.

A separate window for running many agents on many projects at once, showing which are running, done or waiting on you.

Founders can describe an app in Piye Visual and get a real website or a native iPhone, iPad and Android app, see it on real simulators, and publish to the web, the App Store and Google Play.

When they need a developer, Handoff creates a private GitHub repo and branch and writes a HANDOFF.md briefing: what's built, what's missing, which keys are needed. You open it in Piye, or in any editor you like. The project is a normal folder on your computer, with no lock-in.

Free on Mac and Linux, with 750 credits to start (no card): piye.dev I'd really like honest feedback from developers: what's confusing, what breaks, what you'd need before using it every day.
