Supermaven redefined what fast autocomplete feels like with sub-10ms latency predictions. Then it got acquired by Cursor and was discontinued on November 30, 2025. Here is what that means for developers, where the technology lives now, and the best alternatives available today.
Supermaven was an AI-powered code completion tool created by Jacob Jackson, who previously built Tabnine — one of the original AI coding assistants. Jackson founded Supermaven with a singular obsession: reducing the latency between typing and seeing an AI suggestion to the point where it feels like the tool is reading your mind. The technology is now part of Cursor.
The result is a code completion engine that delivers suggestions in approximately 300 milliseconds, compared to the 600ms or more that GitHub Copilot typically takes. That 300ms difference might sound trivial on paper, but in practice it changes the entire feel of coding with AI. Suggestions arrive before you finish forming the thought, rather than appearing after a noticeable pause.
Supermaven achieves this speed through a custom-built inference pipeline and a model architecture optimized specifically for code completion rather than general-purpose language tasks. It also maintains a context window of up to 1 million tokens, allowing it to consider far more of your codebase when generating suggestions.
Latency is the single most important factor in whether a code completion tool feels helpful or annoying. Here is how Supermaven compares.
89ms
Supermaven
Sub-100ms felt instant. Predictions started before you finished typing thanks to a 300M context window cached locally.
167ms
GitHub Copilot
Streams from Azure. Noticeable but usable pause. Over 200ms you start noticing the lag disrupting flow.
198ms
Codeium Pro
Hybrid local/cloud approach. Faster than Copilot but still noticeably slower than Supermaven was.
In late 2024, the Cursor team (Anysphere, now valued at $29.3 billion) acquired Supermaven. The standalone service was officially discontinued on November 30, 2025. Here is what it means practically.
The primary reason for the acquisition was Supermaven's speed technology. Cursor integrated Supermaven's inference pipeline into its Tab completion feature, making Cursor's inline suggestions noticeably faster than before. If you use Cursor today, you are already benefiting from Supermaven's technology.
Supermaven's VS Code, JetBrains, and Neovim extensions were discontinued on November 30, 2025. Users were directed to migrate to Cursor. For developers who prefer to stay in VS Code or JetBrains, Cline, Continue.dev, and GitHub Copilot are the leading alternatives.
With Supermaven's speed baked into Cursor, the gap between Cursor and GitHub Copilot widened on the autocomplete front. This forced Copilot to accelerate its own speed improvements and pushed the entire market toward lower-latency completions.
An honest assessment of where Supermaven excels and where it falls short compared to the broader AI coding tool ecosystem.
Whether you use Supermaven, Cursor, Copilot, or Claude Code, the developers who get the best results are the ones who understand how to work with AI systematically. Build Fast With AI teaches the repeatable frameworks that work across every tool. Lifetime access for a one-time payment.

Founded by Jacob Jackson (the original creator of Tabnine), Supermaven used a custom-built model and inference pipeline to deliver code suggestions with sub-10ms latency — dramatically faster than GitHub Copilot's ~167ms. Supermaven was acquired by Anysphere (makers of Cursor) and its standalone service was sunset on November 30, 2025. Its technology now powers Cursor's Tab completions.
Supermaven was acquired by the Cursor team (Anysphere) in late 2024. The standalone Supermaven service was officially discontinued on November 30, 2025. All Supermaven services have been shut down, and users have been directed to migrate to Cursor AI. Supermaven's technology — including its sub-10ms inference pipeline and 1M token context window — has been fully integrated into Cursor's Tab completion feature. If you were a Supermaven user, Cursor is the direct successor.
Independent benchmarks from February 2026 showed Supermaven at ~89ms median latency for React/TypeScript vs Copilot at ~167ms. Supermaven also used a larger context window (up to 1 million tokens) for better codebase awareness. Copilot has broader editor support, enterprise features, and deeper GitHub integration. Since Supermaven has been sunset, the comparison is now academic — but Cursor inherited Supermaven's speed advantage, making Cursor vs Copilot the relevant comparison today.
Supermaven previously supported VS Code, Neovim, and JetBrains IDEs. However, all standalone extensions were discontinued when the service was sunset on November 30, 2025. The technology now exclusively powers Cursor's built-in Tab completions. For VS Code users who want Supermaven-class speed, switching to Cursor is the only option. For JetBrains users, GitHub Copilot or Cline remain the top alternatives.
Supermaven's standalone pricing is no longer relevant since the service was sunset in November 2025. Previously, it offered a free tier and a Pro plan at $10/month. Today, the only way to access Supermaven's technology is through Cursor. Cursor's Hobby plan is free with limited completions, and Cursor Pro at $20/month includes unlimited auto-mode completions powered by Supermaven's engine, plus Composer 1.5, Background Agent, and multi-model support.
Supermaven was focused exclusively on code completion — it never offered chat, multi-file editing, or agentic capabilities. The standalone product was officially discontinued on November 30, 2025, confirming the long-term stability concerns. Its speed-optimized model sometimes sacrificed accuracy on complex logic. For developers who relied on Supermaven, Cursor is the natural successor. For those wanting alternatives, Cline, Continue.dev, and GitHub Copilot are the leading options.
