Use Claude Code and Reason together
Open Reason on the web or the Mac app
Sign in at reasonmachines.com, or download the Reason app for macOS from reasonmachines.com/download. Both open the same Sessions. Sending work to Reason needs a Pro or Max plan.
Connect your Claude plan
In Settings › Models, choose Connect Claude and sign in with your Claude Pro or Max plan. Reason can then run Claude models on it; that plan's own five-hour and weekly limits still apply.
Hand Reason the work that should keep going
Push the branch you were on in Claude Code and tell Reason in the composer what's done and what's next. It continues on its cloud computer, with your laptop closed, and opens the pull request.
Keep it working when you're away
Mention Reason in Slack to hand it a task from a thread, and set up a Loop for work that repeats, such as a nightly dependency check. Its Sessions run on Reason's cloud computers, so they keep going with your laptop closed.

From Reason's docs and Anthropic's pages, checked Nov 2, 2026. There is no head-to-head public benchmark of the two. On Artificial Analysis's Coding Agent Index v2.0, Claude Code on Opus 5.5 scores 62; Reason's published result is on the earlier v1.5, where it scored 65.1 against Codex's 62.5 on GPT-6 Astra.
When to use which
Use Claude Code when you're at your desk and want Claude in your terminal or editor. Use Reason for work that should run without you: from Slack, on a Loop, on a cloud computer, or on another model when Claude is out. Reason reads the same CLAUDE.md files in your repository, and Claude Code can connect to Reason over MCP from Settings › Channels.
Hit your limit? Reason keeps going on your other connected accounts or Reason credits.
