Claude Code Projects threads can now run on your machine

Threads in Claude Code Projects no longer have to run on Anthropic’s infrastructure. Anthropic’s ClaudeDevs account said in a September 23 post on X that Projects now has local support, so a thread can run on your own machine.

Before this, every thread ran in the cloud. Anthropic’s description of the redesigned projects lays out how they work. A coordinator scopes the request, hands the work to parallel threads, reviews what comes back and assembles the result. Each thread was a full Claude Code cloud session with its own branch and its own copy of the repo. When two threads touched the same code, the clash came back as a merge conflict, like any other PR. A cloud session runs by default in an isolated virtual machine managed by Anthropic. It starts from a fresh clone from GitHub, pushes its branch at a stopping point and keeps going after you close the laptop.

Access is still limited. The beta opened for select Pro and Max subscribers who use cloud sessions in Claude Code and had no existing projects on the web or desktop. Team and Enterprise plans come later. Anthropic says it is working through the waitlist and letting in more Pro and Max users. People who used Claude projects before still haven’t been migrated, and the early access form is at claude.com/form/projects.

Once you’re in, you can create up to 200 new threads per day across all your projects. New projects run threads on Opus at high effort by default, and you can set the model and effort separately for the coordinator and for the workers. That default matters, because several full Claude Code sessions running at once use up plan limits faster than a single chat.
