ThreadlinesvsMonoCode

A MonoCode alternative with several agents in one thread

MonoCode is a free, MIT-licensed app that runs eleven coding agents in tabs and split panes, with an inbox for pull requests and issues. Threadlines is free and MIT-licensed too. It puts several agents in one thread, and an agent on one of your computers can start a thread on another.

Questions

Is MonoCode open source?

Yes. MonoCode is MIT-licensed, like Threadlines. Both are free and use the agent sign-ins you already have.

Does MonoCode run on Windows?

Yes. MonoCode has a Windows installer, plus builds for Mac and Linux.

Can I use both?

Yes. They're separate apps, and both run the agent CLIs already on your computer with your own sign-ins.

We checked these facts about MonoCode on October 29, 2026, against MonoCode's README, changelog, remote access, agent access and iPhone app. Something out of date? Open an issue and we'll fix it.
