Supermaven Review: The Fastest AI Autocomplete?

⏱ 7 Reading Time

Supermaven was an AI code-completion tool built for speed, using a 1-million-token context window to read entire codebases. Anysphere, the company behind Cursor, acquired Supermaven in November 2024 and shut down its standalone product on November 21, 2025.

What Is Supermaven?

Supermaven was a standalone AI autocomplete extension for VS Code, JetBrains, and Neovim, built around a custom low-latency model called Babble and a 1-million-token context window. Jacob Jackson, co-founder of Tabnine, founded Supermaven in 2023. The tool indexed entire repositories instead of the current file, predicted “next locations” for edits across a codebase, and shipped completions with a reported median latency of 89 milliseconds, according to independent benchmarks published by BuildFastWithAI in February 2026. Anysphere, the parent company of the AI code editor Cursor, acquired Supermaven on November 12, 2024, for an undisclosed sum, according to TechCrunch’s report on the deal. Anysphere folded the Supermaven engineering team into Cursor and discontinued the standalone product on November 21, 2025, per Supermaven’s official sunset announcement on its company blog.

Is Supermaven Still Available in 2026?

Supermaven is not available as a new signup in 2026. Anysphere refunded all active subscribers on November 21, 2025, and stopped selling the Pro plan, according to Supermaven’s sunset blog post. The company continues to run free autocomplete inference for existing Neovim and JetBrains users “for the foreseeable future,” but it removed agent-chat conversations from the product entirely. VS Code users received no legacy exception and were instructed to migrate to Cursor’s Tab autocomplete feature, which now runs on Supermaven’s original inference pipeline. Anyone searching for Supermaven today is choosing between a frozen legacy extension (JetBrains or Neovim only) and its direct successor, Cursor.

What Were Supermaven’s Key Features?

Supermaven combined a 1-million-token context window with a custom inference engine tuned for sub-100ms completions. Its core capabilities, while the standalone product was active, included:

• Index the full codebase into a 1-million-token context window on the Pro plan, versus 300,000 tokens on the Free plan, according to ToolChase’s pricing verification.
• Predict next-edit locations across files using a feature called “jumps,” guiding developers to the next relevant line before they type it.
• Adapt completions to a project’s existing naming conventions and formatting patterns on the Pro tier.
• Generate inline suggestions with a median latency of 89 milliseconds for React and TypeScript projects, compared to GitHub Copilot’s 167 milliseconds in the same February 2026 benchmark set.
• Integrate with VS Code, JetBrains IDEs (IntelliJ, PyCharm, WebStorm, Rider, CLion, GoLand, PhpStorm), and Neovim.
• Support chat sessions with GPT-4o and Claude 3.5 Sonnet inside the editor, a feature Anysphere removed entirely during the November 2025 sunset.

How Much Does Supermaven Cost?

Supermaven no longer charges for any tier; new signups are closed, and legacy JetBrains and Neovim users receive free autocomplete inference indefinitely. Before the shutdown, Supermaven billed two tiers, verified on supermaven.com/pricing as of April 2026 archive data:

Anysphere refunded all Pro subscribers for unused time on November 21, 2025, the same day it announced the sunset, according to the official Supermaven blog. Developers who want the 1-million-token context window and continued model updates now pay for Cursor Pro at $20/month, which runs on the upgraded version of Supermaven’s inference engine, per BuildFastWithAI’s March 2026 review.

What Are the Pros and Cons of Supermaven?

Supermaven delivered the fastest inline completions of any standalone autocomplete tool tested in 2025, but its discontinuation eliminated the product’s long-term viability.

Pros:

• Fastest median completion latency in independent 2026 benchmarks: 89ms versus Copilot’s 167ms.
• Largest context window in its class at launch: 1 million tokens versus GitHub Copilot’s file-level context at the time.
• Free legacy access for existing JetBrains and Neovim users continues past the shutdown date.
• Minimal setup: the extension required no repository re-indexing step for small projects.

Cons:

• Standalone product discontinued on November 21, 2025; new users cannot sign up.
• VS Code users lost all legacy access and must migrate to Cursor.
• No agentic capabilities, multi-file editing, or terminal execution — Supermaven never expanded beyond inline completion and basic chat.
• Chat and agent conversations were removed from the legacy free tier during the sunset.
• Refund and cancellation friction was a recurring complaint in SourceForge user reviews prior to the shutdown.

How Does Supermaven Compare to Cursor?

Cursor is Supermaven’s direct successor and now runs Supermaven’s original inference technology inside its Tab autocomplete feature. Anysphere integrated Supermaven’s low-latency model into Cursor Tab immediately after the November 2024 acquisition, then finished the transition by retiring Supermaven outright in November 2025.

Developers weighing this decision should read Knowara’s dedicated Cursor vs GitHub Copilot comparison for a full feature-by-feature breakdown before migrating.

Who Should Still Use Supermaven Today?

Supermaven in 2026 fits only two narrow user groups: existing JetBrains users and existing Neovim users who already have the extension installed. These developers keep free, actively-served autocomplete inference without paying for Cursor’s Pro tier. Every other developer profile — solo indie developers starting fresh, VS Code users, enterprise teams standardizing on one AI coding tool, and anyone who wants chat or agent features — has no path to Supermaven and should evaluate Cursor or a competing autocomplete tool instead.

What Are the Best Alternatives to Supermaven?

Cursor, GitHub Copilot, and Windsurf are the three most relevant alternatives to Supermaven in 2026.

• Cursor runs Supermaven’s own inference technology inside its Tab completion feature and adds full agent mode, multi-file editing, and terminal command execution. Read Knowara’s full Cursor AI Review for pricing tiers and benchmark scores.
• GitHub Copilot offers the broadest IDE support and deepest GitHub integration, priced at $10/month for the Individual plan, but posted a slower 167ms median completion latency in the same February 2026 benchmark that measured Supermaven.
• Windsurf competes on a similar large-context, low-latency positioning and is covered in Knowara’s Best Free AI Coding Tools roundup alongside other budget-friendly options.

Frequently Asked Questions

Is Supermaven still available to download?

No. Anysphere closed new signups on November 21, 2025. Existing JetBrains and Neovim users retain free access; VS Code users have no legacy option and must switch to Cursor.

Did Supermaven get acquired by Cursor?

Yes. Anysphere, Cursor’s parent company, acquired Supermaven on November 12, 2024, for an undisclosed sum, according to TechCrunch.

Is Cursor the same as Supermaven?

No. Cursor is a separate, full AI-native code editor that now runs Supermaven’s original low-latency inference model inside its Tab autocomplete feature.

What replaced Supermaven’s chat feature?

Anysphere removed chat and agent conversations from Supermaven entirely during the November 2025 sunset and directs former users to Cursor’s agent mode for equivalent functionality.

Verdict

Supermaven’s standalone product is discontinued as of November 21, 2025: new signups are closed, VS Code access is gone, and only existing JetBrains and Neovim users retain free autocomplete inference. For every other developer, Cursor — running Supermaven’s own inference engine — is the only active path to the technology this review originally set out to test.
