Fast long-context code-completion copilot, now folded into Cursor
Last reviewed 2026-06-19
Supermaven was a low-latency code-completion copilot built around a proprietary model (Babble) with an unusually large context window, marketed as "the fastest copilot." Launched in February 2024 by Jacob Jackson (who previously created Tabnine), it provided inline autocomplete across VS Code, JetBrains, and Neovim, and later added chat and an Agent mode built on third-party models. Supermaven was acquired by Anysphere, the maker of Cursor, in November 2024, and the team went on to build Cursor's Tab autocomplete model. The standalone product was sunset in late 2025: chat and Agent were discontinued, VS Code users were directed to migrate to Cursor, and existing subscribers received prorated refunds. As of this review it is documented here as historical, with Cursor as the official successor.
What it can do
Complete code inline
CopilotSuggests inline code completions as you type; the developer accepts or rejects each suggestion.
sourceUse long-context awareness
CopilotIts Babble model expanded the context window to a reported 1 million tokens for more codebase-aware completions (vendor claim).
sourceChat about code (discontinued)
AssistantOffered conversational chat built on GPT-4o and Claude 3.5 Sonnet; discontinued during the 2025 sunset.

Strengths
- +Genuinely fast, low-latency completions
- +Very large (reported 1M-token) context window for codebase-aware suggestions
- +Lightweight drop-in across VS Code, JetBrains, and Neovim
Limitations
- −Discontinued as a standalone product; new users should use Cursor
- −Narrow scope: primarily autocomplete, with chat later removed
- −Acquisition into a competitor's editor realized continuity risk for standalone users
Overview
Supermaven was a low-latency code-completion copilot built on a proprietary model (Babble) with a large context window, marketed as the fastest copilot. It is documented here as historical: it was acquired by Anysphere and sunset as a standalone product.
What it does
Supermaven provided inline code completion across VS Code, JetBrains, and Neovim, with a reported 1 million-token context window for more codebase-aware suggestions. It later added chat and an Agent mode built on GPT-4o and Claude 3.5 Sonnet, both of which were discontinued during the sunset.
History
Founded in February 2024 by Jacob Jackson (creator of Tabnine), Supermaven was acquired by Anysphere, the maker of Cursor, in November 2024 on undisclosed terms. The team went on to build Cursor's Tab autocomplete model. The standalone product was sunset in late 2025, with users directed to Cursor and prorated refunds issued to subscribers. Reported adoption figures at launch were in the tens of thousands of developers.
Pricing
Historical: a free tier and a $10/mo Pro tier. New paid signups are effectively gone.
