Cursor is an AI-powered code editor built as a fork of VS Code, designed to accelerate software development through deep AI integration. The editor provides AI-assisted code completion, multi-file editing through Composer, codebase-aware chat, and intelligent code generation that understands project context. Cursor has rapidly gained adoption among professional developers who want AI coding assistance integrated directly into their development environment rather than switching between an editor and a separate AI chat interface. The platform supports multiple AI model backends including GPT-4 and Claude.
Cursor outages primarily affect the AI-powered features rather than the editor itself, since the VS Code base continues functioning locally. Common causes include API infrastructure failures for the AI completion and chat services, model serving capacity constraints during peak coding hours, and authentication service disruptions preventing Pro subscribers from accessing premium features. Rate limiting during high-demand periods degrades autocomplete responsiveness. Backend infrastructure updates occasionally introduce regressions in the Composer multi-file editing feature.
When Cursor's AI services go down, the editor reverts to a standard VS Code experience without AI assistance. Developers lose Tab autocomplete suggestions, Composer multi-file editing capabilities, and contextual code chat. While existing code can still be edited manually, the productivity loss is significant for developers who have built their workflow around Cursor's AI features. Premium subscribers paying for faster models experience the most noticeable impact during degradation events.
Use this page to check Cursor AI service availability. The Cursor editor itself runs locally and works without AI features, but AI completions, chat, and Composer require server connectivity. Check status.cursor.com for official incident reports. If the editor works but AI features do not respond, it is an AI backend issue.
Autocomplete failures typically result from AI service outages, rate limit exhaustion on your subscription tier, network connectivity issues, or authentication problems. Check if Cursor's chat feature also fails — if both are down, it is a platform-wide AI service issue. Try logging out and back in to refresh your authentication token.
Yes, Cursor is built on VS Code, so all standard editing features work locally without internet connectivity. You lose AI autocomplete, Composer, and chat capabilities, but code editing, terminal, debugging, Git integration, and extensions continue functioning. The editor degrades gracefully to a standard VS Code experience during AI outages.
Cursor offers deeper AI integration with multi-file editing through Composer and codebase-aware context, while GitHub Copilot provides inline suggestions within existing editors. Cursor uses multiple AI model backends. Copilot benefits from GitHub's massive training data. Both experience occasional AI service outages, so maintaining familiarity with both tools provides a fallback.
