Supermaven
Ultra-fast 300,000-token context AI code completion engine
About Supermaven
Supermaven is an ultra-low-latency AI code completion extension engineered by the creators of TabNine. Renowned for its industry-leading response speed and massive 300,000-token context window, Supermaven delivers sub-100ms inline suggestions that feel instant compared to traditional LLM copilot extensions. By ingesting your entire repository into its specialized Babble neural architecture, Supermaven understands project-wide type definitions, custom internal libraries, coding conventions, and recent file edits with unprecedented accuracy. Available across Visual Studio Code, JetBrains IDEs, and Neovim, Supermaven offers a generous free tier for individual developers alongside a high-context Pro tier for professional engineers.
Supermaven's competitive edge stems from its proprietary Babble model architecture, which is specifically trained for low-latency next-token code synthesis rather than heavy generalized conversation. This design enables Supermaven to stream full multi-line code completions in under 50 milliseconds. The 300,000-token context window allows the model to maintain the entire working state of medium-to-large codebases in memory simultaneously. When you refactor a data model or add a new API route, Supermaven immediately adapts its completions across all related controllers, frontend components, and test files. Supermaven also enforces enterprise-grade security protocols, ensuring that proprietary source code is never stored or used for foundational model training.
Install the Supermaven extension from the VS Code Marketplace, JetBrains Plugins, or Neovim package manager.

Frequently Asked Questions
How is Supermaven faster than GitHub Copilot?
Supermaven uses a custom-engineered Babble model specifically optimized for streaming next-token code latency, achieving response times under 50ms compared to Copilot's 200-400ms latency.
What is Supermaven's 300,000 token context window used for?
The 300k context window allows Supermaven to hold your entire repository in memory, giving suggestions full awareness of all functions, types, and recent edits across files.
Can I use Supermaven in Neovim and JetBrains?
Yes, Supermaven offers official native plugins for Visual Studio Code, JetBrains IDEs (IntelliJ, WebStorm, PyCharm), and Neovim.
