I got tired of having 4 AI agents in 4 terminal windows, so I built this

For the last few months I've been using Claude Code, Copilot CLI and Codex pretty much daily. Sometimes Aider too. And the workflow was always the same mess: open a terminal, run one agent,
open another terminal, run another, lose track of which window is which, miss a "[y/N]" prompt for half an hour because it was buried behind something else.

At some point I gave up and built my own thing for it. It's called Flowyble Studio.

https://studio.flowyble.com

It's basically a desktop app that runs all your AI coding agents in one window, in a split layout, per project. You pick a folder, pick which agents you want, and they all start side by

side. When you switch to another project, that's a different tab with its own panels and its own state.

A few things I cared about while building it:

The agent activity sidebar. Every panel reports if its agent is active, idle, waiting for input, or errored. This is the feature I actually use the most, because the real productivity

killer with multi-agent workflows isn't speed, it's missing the moment one of them stalls on a confirmation prompt.

Sessions just persist. Close the app, reopen it tomorrow, your tabs and layouts are still there. Sounds boring but every other terminal setup I tried lost state somewhere.

Drag and drop on panels. I went through three layout systems before landing on a binary split tree where you can grab any panel and drop it left/right/top/bottom of any other one. Feels

obvious in hindsight.

It also does Git status in a sidebar, build/run for .NET, Python, Node, Go, Java and Rust, and voice input through Whisper if you're into that. There's some custom-agent stuff too if you

want to plug in something that isn't on the built-in list.

Stack-wise it's Avalonia on .NET 10, with WebView2 hosting xterm.js for the actual terminals, and Windows ConPTY underneath. One self-contained binary, no installer drama.

Free. No account. No usage limits. I'm not monetizing it right now and I don't have plans to put it behind a paywall. Windows 10+ and Linux x64 (AppImage), Mac is on the maybe pile.

If any of this sounds useful, grab it here: https://studio.flowyble.com

I'd genuinely love feedback. Especially from anyone running 3+ agents at once, because that's where I designed the whole thing for and I'm sure I missed cases. Comments are open.
