AI code completion tool with extremely fast suggestions and 1 million token context window for understanding large codebases.
Ultra-fast AI code completion that reads huge amounts of your code for context â suggestions that understand your entire project.
Supermaven is an AI-powered code completion tool built for speed, delivering code suggestions approximately 3x faster than leading competitors with an average latency of just 250 milliseconds. Created by Jacob Jackson, a former OpenAI engineer, Supermaven is purpose-built to handle the demands of professional development environments where responsiveness and accuracy are paramount. Its standout feature is a 1 million token context window â the first code completion tool to offer this capability â which allows it to understand vast portions of your codebase simultaneously, including cross-file definitions, types, and patterns, resulting in highly contextual and accurate suggestions.
Supermaven integrates seamlessly with the most popular development environments including VS Code, JetBrains IDEs, and Neovim, making it accessible to a wide range of developers. Beyond code completion, Supermaven includes a built-in chat interface that supports multiple leading AI models including GPT-4o, Claude Sonnet, and GPT-4. The chat feature is tightly integrated with the editor, allowing developers to view diffs, apply code changes, attach recently edited files, and fix compiler errors with a single click â all through keyboard-driven workflows designed for efficiency.
Supermaven is designed for individual developers and teams alike, with plans ranging from a generous free tier to team plans with centralized management. The tool adapts to your personal coding style over time on Pro and Team plans, learning your conventions and patterns to provide increasingly relevant suggestions. For developers working with large enterprise codebases who need a fast, context-aware coding assistant that doesn't slow them down, Supermaven offers one of the most performant solutions available today.

Supermaven stands out as one of the fastest AI code completion tools available, delivering suggestions at roughly 250ms â about 3x faster than leading competitors. Its 1 million token context window on Pro and Team plans enables deep cross-file understanding of large codebases, producing highly contextual completions that correctly reference types and definitions across your project. The integrated multi-model chat, support for VS Code, JetBrains, and Neovim, and adaptive coding style learning make it a strong choice for professional developers. The free tier is generous for core completions, though the full context window and personalization require a paid plan. Editor support is limited to three platforms, and chat credits are capped, but for speed and context-aware accuracy, Supermaven is a top-tier option.
Supermaven delivers code suggestions at approximately 250ms latency, roughly 3x faster than leading competitors. This near-instant response time eliminates the perceptible delay common in other AI coding tools, allowing developers to maintain their natural typing flow without waiting for suggestions to appear.
As the first code completion tool to offer a 1 million token context window, Supermaven can analyze vast sections of your codebase simultaneously. This allows it to find type definitions, function signatures, and patterns across many files, producing suggestions that correctly reference your project's actual code rather than making generic completions.
Supermaven's built-in chat interface supports GPT-4o, Claude Sonnet, GPT-4, and other leading models directly within your editor. The chat is deeply integrated with your code â you can attach recently edited files, view diffs of suggested changes, apply modifications directly, and fix compiler errors by uploading diagnostics in a single click.
Supermaven analyzes definitions, types, and structures across your entire project to provide contextually accurate suggestions. For example, if a type like PostMetadata is defined in one file and used in another, Supermaven finds that definition and uses it to suggest correctly typed code, reducing errors and the need to manually reference other files.
On Pro and Team plans, Supermaven learns and adapts to your individual coding style and project conventions over time. This means suggestions progressively align with your naming conventions, formatting preferences, and architectural patterns, making the tool more useful the longer you use it within a project.
