What this page does not answer

Neither Bolt.new nor Cursor has been researched. Every line above is a number read from a repository on the date beside it, so this page compares the two projects and not the two products: it says nothing about who each tool suits, what it is bad at, or what it costs today. We have written those judgments for 12 tools so far and neither of these is one of them.

How we check this page

Machine facts. Stars, contributors, the newest commit on the default branch, the licence GitHub reports and the latest stable release come from the GitHub API, and download counts from npm, PyPI, Homebrew and the VS Code Marketplace. Each value carries the day it was last confirmed, never the day this page was built. The line under each label is arithmetic on those two values.
Judgments. Every claim about what a tool suits, what it is bad at and what it costs is quoted from a page we read, and that page is linked beside the claim. Where there is no link, we wrote no claim.
Index status. Neither tool is researched, and both repositories are tracked, so the two can be set against each other on facts. So this page is offered to search engines.
