Claude Code new feature /ultraplan: Create an implementation plan on the web, then run it with one click after editing

Anthropic product lead trq212 announced on April 10 that Claude Code has added the /ultraplan feature, letting developers create a complete implementation plan in the web interface, edit and adjust it, and then choose to run it on the web or return to the terminal. The preview is already available to all users who have enabled Claude Code on the web.

Plan in the cloud, run locally

The core idea behind /ultraplan is to separate “planning” from “execution.” trq212 explains that implementation sometimes requires a local environment and interactivity, but planning can be done in the cloud because it mainly involves reading code and understanding intent.

This addresses a common pain point for Claude Code users: when using /plan in the past, the plan was generated in the terminal, making it difficult to get an overview and edit. /ultraplan moves the plan to the web interface, providing a better visualization and editing experience, so developers can fully review and adjust the plan before executing.

Differences from /plan

The number of tokens used by /ultraplan and its subscription rate limits are roughly the same as /plan, and it won’t consume additional usage. The main difference is the user experience: the web interface offers better capabilities for reading, editing, and sharing.

The community’s response has been enthusiastic, with some developers saying this makes Claude Code “no longer feel like a black box, but more like a senior developer companion.” Others have complained that all usage is used up within the first 30 minutes—showing that demand is very strong.
