Stop babysitting CI just to press merge.
Open the PR popup above the message box and turn on Merge when checks pass. If the repo has GitHub auto-merge turned off, Threadlines waits for the checks and does the merge itself while the app is running.

Opus 5.5 is the first Opus I don't ration. I usually cap my models at High reasoning. I've been running this one on Max, and it still barely dents my usage.
It's in the Threadlines model picker now. You'll need Claude Code 2.1.280 or newer.
How's it been for you so far?

First run should tell you what to do next. Threadlines checks your coding agents and Git tools, shows what needs installing or signing in, and gets you to your first thread. You only need one agent ready to begin.

Might be a little too proud of our Git graph.
A lot of PRs have gone into Threadlines, and I love seeing the work add up.
We're building a home for coding agents, with your threads, diffs, and Git history in one place.

I specifically made our reset UI show the countdown buy I also missed it today because I was trying to token max and use it at the very last second and got distracted. 🤦♂️( img from like 3 hours ago)

Took me 5-6 days but we have a Beta version of the inbox style workflow and I'm really enjoying the workflow. Thanks for the inspo, @theo you were right lol
I give it 10 days before everyone starts copying this workflow. Seriously can't believe we've been dealing with single rows of text for over a year.

Kimi-K3 beats Claude Fable 5 in frontend according to arena.ai is this true?? Has anyone tested it?

Steer instead of re-prompting. Select the exact lines you mean from code, agent output, or the terminal, then attach that selection to your next message.

Project files are a workspace, not a side panel. Browse and search the repo, open real tabs, then edit and save without leaving the conversation.

The git graph is where the name comes from. Branch lanes, merges, and tags you can actually follow, next to the agent's work. Click any commit for author, SHA, and changed files.

This is the panel that started the whole fork. Staged and unstaged changes grouped by file, per-file diffs, and per-file undo. It's the source control view I missed, sitting right next to the agent.

Threadlines is open source as of today.
It's a desktop GUI for Claude Code and Codex. A real source control panel, a built-in file editor, switching providers mid-thread, and you can revert anything an agent did. MIT, free, macOS and Windows.
This is my first major open source release and not something I ever pictured myself doing. None of it would exist without @theo and @jullerino. They built T3 Code, made it open source, and have kept making it better constantly ever since. I came to T3 Code from Cursor and loved it. The only thing I missed was a proper source control panel like VS Code and Cursor have, so I forked it to build that for myself. The fork slowly grew into its own app, but the foundation and a thousand good decisions inside it are theirs.
I've watched Theo's videos and streams for a long time and posted maybe twice. Lurker through and through. But somewhere between all those videos I picked up the tools and the motivation to build this. Releasing my own fork of his project feels like a strange full-circle moment. If Threadlines ends up being useful to anyone, a lot of that credit belongs to them. Thank you both.

Its happening! We missed you so much Fable! Can’t wait to work with you once again my old friend.
We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.
