Cursor

What Cursor is

Cursor is the AI code editor from Anysphere, Inc., founded in 2022 in San Francisco by MIT classmates Michael Truell, Sualeh Asif, Aman Sanger, and Arvid Lunnemark. Built as a fork of VS Code, it layers Cursor Tab autocomplete, the Composer 2.5 model, codebase chat, and Agent mode on top of a multi-model backend. Cursor has since been acquired by SpaceX: Cursor's own blog announced on August 14, 2026 that it is 'now a part of SpaceX', completing an acquisition that began with an April 2026 partnership with SpaceXAI to accelerate model training. Cursor cites access to the world's largest GPU fleet and co-development of Grok 4.6 as early results of the combination.

Key features

• Cursor Tab — multi-line autocomplete that predicts the next edits across files
• Composer 2.5 — Cursor's own in-house coding model, available from the free Hobby tier upward
• Agent mode — autonomous agents that search the codebase, edit files, and run terminal commands
• Codebase chat — natural-language Q&A across the whole repository
• Cloud Agents and Cursor CLI for headless, scheduled, and Slack-triggered automations
• Bugbot — automated GitHub PR review, now billed on usage
• Access to frontier models — including Claude Opus 5 / Sonnet 5, Claude Fable 5.1, GPT-5.6 Sol / Terra / Luna and Gemini 3.8 Flash — plus Grok 4.6, jointly trained by Cursor and SpaceXAI, with Grok Bot access included on Pro and above
