Cursor released Cursor 3 on April 2, 2026 under the codename Glass — repositioning the product from an AI coding assistant into a full agentic coding interface designed to own the complete workflow of writing, reviewing, and shipping code. Unlike earlier Cursor versions that provided tab completion and inline suggestions, Cursor 3 can plan multi-file changes, reason about the broader codebase architecture, execute sequences of edits, and run tests autonomously before presenting a diff for developer review. The launch positions Cursor 3 directly against Anthropic's Claude Code and OpenAI's Codex, which have each reached millions of developers by enabling agentic code generation — and establishes Cursor as the independent interface competitor in a market where both labs also sell first-party coding tools. For teams that want model flexibility without being locked to OpenAI or Anthropic's own interfaces, Cursor 3 is the leading independent option.
