AI-powered code editor and IDE built on VSCode with Composer 1.5 for multi-file editing, Background Agents for autonomous coding, and support for frontier models from OpenAI, Anthropic, Gemini, and xAI.
Cursor IDE, developed by Anysphere, a Y Combinator-backed startup founded in 2022, has emerged as the leading AI-powered code editor in 2026, fundamentally changing how developers write, review, and ship code. Cursor is an AI-assisted integrated development environment for Windows, macOS, and Linux that is a fork of Visual Studio Code with additional AI features.
Cursor is now available in IntelliJ IDEA, PyCharm, WebStorm, and other JetBrains IDEs through the Agent Client Protocol (ACP), allowing developers who rely on JetBrains for Java and multilanguage support to use any frontier model from OpenAI, Anthropic, Google, and Cursor for agent-driven development.
This release introduces interactive UIs in agent chats, a way for teams to share private plugins, and improvements to core capabilities like Debug mode, with MCP Apps supporting interactive user interfaces like charts from Amplitude, diagrams from Figma, and whiteboards from tldraw directly inside Cursor.
Composer 1.5 offers multi-file AI editing with 20x scaled reinforcement learning, self-summarization for long contexts, and 60% latency reduction.
Background Agents launch AI coding tasks that run autonomously while you continue working on other files, while BugBot provides automated bug detection that scans your codebase and identifies potential issues before they reach production.
Users can choose freely between frontier models from OpenAI, Anthropic, Gemini, and xAI.
What began as an experimental fork of Visual Studio Code has evolved into a platform trusted by some of the world's most influential technology companies, from Stripe and NVIDIA to Salesforce and Shopify.
