Questions
Is Threadlines a fork of T3 Code?
Yes. Threadlines started from T3 Code and keeps its MIT license and Git history. It has its own direction now, and improvements still flow back when they fit.
Can I use both?
Yes. They're separate apps with separate data, and both run the agents with the sign-ins already on your computer.
We checked these facts about T3 Code on October 18, 2026, against T3 Code's README, v0.1.0 release notes and user docs. Something out of date? Open an issue and we'll fix it.
