Caret

An ultralight coding agent in your browser

Caret review view: the agent’s diff, task steps and files waiting to be applied

Tired of slow, tedious verification?

Go to the extreme and drop Bash, keeping just three tools. An ultralight, minimal coding agent that runs entirely in the browser. Perhaps when AI is strong enough, there is nothing to verify: you just do it.

Caret settings: choose a model service, enter an API key, and pick a default model and reasoning effort

Or it may just be a tiny change

Change some copy, a color or a position, and a glance at the diff is verification enough. There is no heavyweight desktop-agent development environment, and unnecessary tests are left behind.

No hidden memory

It is all in AGENTS.md and CLAUDE.md. What you see is what the AI sees.
