Supermaven
The fastest AI autocomplete around, powered by a huge context window.
What is Supermaven?
Supermaven is an AI code-completion tool built to win on raw speed — suggestions appear with almost no perceptible lag, and it reads a much larger chunk of your codebase than most competitors before suggesting anything. It plugs into VS Code, JetBrains, and other editors as a lightweight "Tab" experience rather than a full chat-based assistant.
Supermaven was built by a small team betting that latency and context length, not flashy chat interfaces, are what actually make autocomplete useful day to day. Its context window is large enough to take in whole files or several related files at once, which noticeably sharpens suggestion relevance compared to tools that only see a few hundred lines around the cursor. It has since been folded into Cursor's team, though it still ships as a standalone extension.
Key features
- Extremely low-latency inline code suggestions
- Large context window covering multiple files
- Lightweight editor extension, not a full IDE fork
- Works alongside existing AI chat tools
- Support for VS Code, JetBrains, and Neovim
- Simple, distraction-free "Tab to accept" workflow
Pros
- Speed is noticeably better than most autocomplete competitors
- Large context genuinely improves suggestion relevance
- Cheap and lightweight next to full agentic IDEs
Cons
- No built-in chat or agent mode — it only autocompletes
- Now under Cursor's ownership, so its independent roadmap is unclear
- Less useful for anyone wanting an assistant to plan multi-file changes
