Claude Code v2.1.92 introduced Ultraplan, a planning mode that moves plan review out of your terminal and into a browser tab. Plans are drafted and saved to the cloud, your browser opens automatically to display them, and execution only begins once you approve.
The previous workflow coupled planning and execution tightly - Claude generated a plan and began acting on it immediately. You could interrupt, but the review happened in the same terminal window where files were already being changed. Ultraplan splits these into two distinct phases with an explicit human checkpoint between them.
Plan mode in Claude Code already existed as a way to see Claude's intended approach before it started writing. Ultraplan extends this with cloud persistence and a browser-based interface - useful when a plan spans a dozen files or needs more context than comfortably fits in a terminal window.
The practical difference is clearest on complex, multi-step tasks. When Claude is about to touch multiple files across a project, a quick approval in the terminal is risky. The browser view gives you space to read the full sequence, catch wrong assumptions - "Claude thinks I want to refactor authentication, but I only want to add a route" - and reject the plan before a single file changes.
The browser format also creates options that didn't exist before: share the plan with a teammate for sign-off, paste it into a project ticket as documentation, or compare it against a spec doc before approving. That's a small but real workflow addition for anyone using Claude Code in a team context rather than solo.
The "execute anywhere" part of the release means the plan and execution environment are fully decoupled. You draft and review in one place, run the execution in whatever environment makes sense - local machine, remote server, or a CI pipeline.
No pricing changes were announced with v2.1.92. Ultraplan is available now for Claude Code subscribers.
