Supermaven
Fastest AI code completion with a 1-million-token context window — built by Jacob Jackson (acq by Cursor in 2024). Faster than Copilot, longer context than competitors.
Overview
Supermaven: Fastest Long-Context Code Completion
Supermaven is an AI code completion tool from Jacob Jackson (formerly at Tabnine) that pioneered the long-context approach — originally a 300,000-token context window, now 1 million tokens — and is benchmark-faster than GitHub Copilot in latency. Acquired by Cursor in 2024 to power Cursor's completion model, but the standalone Supermaven product continues to ship for VS Code, JetBrains IDEs, and Neovim.
The two product positionings (standalone editor extension + powering Cursor) make Supermaven simultaneously a category staple and a piece of the broader AI IDE infrastructure.
Key Features
- 1-million-token context window (longest in code completion category)
- Sub-100ms suggestion latency (faster than Copilot)
- Works in VS Code, JetBrains IDEs, and Neovim
- Custom in-house model trained for code completion specifically
- Free tier; paid tier for higher limits and team features
Ideal Use Case
Developers in large codebases where 1M-token context lets the model understand the broader project, teams using non-VS Code editors (JetBrains, Neovim) where Copilot integration is weaker, and engineers who care about completion latency as a UX bottleneck.
Why Use Supermaven
Most code completion tools cap context at 8k–32k tokens; Supermaven's 1M token window changes what's possible (the model can understand multiple files of context for each suggestion). Combined with industry-leading latency, it's a different productivity tier.
FAQ
What does Supermaven do? Supermaven is an AI code completion tool that provides real-time suggestions as you write code. It features a 1-million-token context window, allowing it to understand and reference much more of your codebase than typical alternatives.
Who should use Supermaven? Supermaven is designed for developers who want faster code completion and need to work with larger codebases. It's particularly useful for teams and individuals who value speed and extended context awareness in their coding workflow.
How much does Supermaven cost? Supermaven operates on a freemium model with free and paid tiers available. Visit the Supermaven pricing page for current plans and details on what each tier includes.
How does Supermaven compare to other code completion tools? Supermaven is built to be faster than GitHub Copilot and offers a longer context window than most competing solutions like Cursor and v0. It was created by Jacob Jackson and acquired by Cursor in 2024, combining focused code completion expertise with broader development tools integration.
tl;dr
1M-token context, sub-100ms latency code completion. Acquired by Cursor in 2024. Available standalone for VS Code, JetBrains, Neovim.

Editorial Review
Our take on Supermaven.
Supermaven is an AI code completion tool with a 1-million-token context window and response speed that outpaces Copilot, now integrated into Cursor after its 2024 acquisition.
What works
- 1-million-token context window outranks competitors
- Demonstrably faster inference than Copilot
- Now integrated into Cursor, reaching broader audience
What doesn't
- Smaller ecosystem than GitHub Copilot; not mainstream
- Adoption/data harder to assess post-acquisition
Supermaven was built by Jacob Jackson to solve two concrete problems: Copilot's latency and context limits. The 1-million-token window is a real differentiator—it means the model can see your entire codebase in a single request, not just the current file or a few kilobytes of surrounding context. That changes what completion can do: fewer hallucinations, better long-range consistency, smarter refactoring suggestions. Speed matters too; if you're waiting 2–3 seconds for an autocomplete, you're context-switching out of flow. Supermaven was measured faster than Copilot at the time of release.
The tool operated as a freemium service with both free and paid tiers before Cursor acquired it in 2024. If you're already using Cursor, Supermaven's engine is now built into that editor, so the distinction matters less. If you're evaluating standalone code completion, Supermaven's context window and latency profile make it worth a benchmark against Copilot or Claude—the tradeoff is that you're on a smaller platform than GitHub's ecosystem.
The 4.82 community rating is solid, though the 335 likes suggest it's not a mainstream tool yet. Adoption likely accelerated post-acquisition into Cursor, but if you're using another editor, you'd be pulling in a third-party plugin or extension.
