Cursor

Anysphere

AI-first code editor, forked from VS Code, with an agent mode that makes multi-file changes autonomously, runs terminal commands and iterates against errors. The agent works alongside manual editing rather than replacing it, and a background agent completes tasks asynchronously.

Scored for the autonomous agent mode; the chat-editor surface would belong in ui_api. Verified 2026-08-13 via the Cursor product site and the SWE-bench coding-agent leaderboard.

closed(cursor/cursor holds only .github, README.md and SECURITY.md

Fully proprietary commercial product with no open source license and no public source. A direct read of the repo and the terms settles it: the GitHub contents API shows cursor/cursor holds exactly three entries (.github, README.md and SECURITY.md), the repo API reports no license and no language, and the Terms of Service state that Anysphere and its licensors retain all right, title and interest in the Service and reserve all rights not granted. None of the editor runtime is published, so there is no public core for a gating question to apply to.

Adoption

4 high confidence
4.0

More than 1 million daily active users, sustained since it was first reported, and roughly $2B ARR, both confirmed through press coverage of company-reported figures. That puts Cursor in the 1-10M band; there is no confirmed mass-market count above 10M yet. What is banded is a daily active count read against a monthly scale, so the monthly figure is higher than the number banded and this level is a floor rather than a ceiling.

Capability

4 medium confidence
4.0

High-tier autonomous coding agent: Cursor's Background Agent scores 65.7% on SWE-bench Verified, just below OpenHands at 68.4%, on top of a mature Composer and agent UX. The figure comes from an aggregator leaderboard (awesomeagents.ai) rather than a primary publication, which is why confidence stays medium.
