Cursor vs JetBrains AI: Coding Agents Comparison

Cursor is an AI-native code editor built as a fork of VS Code, designed from the ground up for AI-assisted development. Created by Anysphere, a company founded in 2022 by Michael Truell (CEO), Sualeh Asif, Arvid Lunnemark, and Aman Sanger, Cursor has become the fastest-growing SaaS product in the AI coding space.

The editor features intelligent code completion, multi-file editing, codebase-aware chat, and an agent mode that can autonomously plan and execute coding tasks. Cursor indexes your codebase to create vector representations for accurate, project-specific suggestions rather than generic code. It supports 26 LLMs from OpenAI, Anthropic, Google, xAI, and DeepSeek, with quick integration of new models as they release.

Cursor reached $100 million ARR in January 2025 within 20 months of launch, growing to $500 million ARR by November 2025. The company raised $3.5 billion in total funding at a $29.3 billion valuation. With over 1 million daily active users and 50,000+ business customers, Cursor has a thriving community of 73,000+ subreddit members and 30,000+ GitHub stars.
