ThreadlinesvsOrca

An Orca alternative with several agents in one thread

Orca is a free, MIT-licensed app that runs dozens of coding agents, each in its own Git worktree, with phone apps and remote servers. 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 Orca open source?

Yes. Orca is MIT-licensed, like Threadlines, and both are free.

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 Orca on October 29, 2026, against Orca's README, supported agents, chat docs, mobile, remote servers, automations, GitHub review and ways to run. Something out of date? Open an issue and we'll fix it.
