Pricing

Free plan$0
Pro$10/mo
Team$10/seat/mo

Features

  • 1M-token context window

    Pro adds a 1 million token context window for professional-size codebases, billed as the first code completion tool with a window that large.

  • Codebase-aware suggestions

    Definitions found elsewhere in the codebase, such as a type, are used to produce the right inline suggestions.

  • Low-latency completion

    The site lists 250 ms latency against 783 ms for a leading competitor, across VS Code, JetBrains IDEs and Neovim.

  • Supermaven Chat

    Chat works with GPT-4o, Claude 3.5 Sonnet and GPT-4, with hotkeys to view diffs, apply changes, start conversations and switch models.

  • One-click error fixes

    Code is uploaded together with compiler diagnostic messages in a single click to fix errors.

What users say

Pros

  • Completions arrive very fast and stay consistent, clearly outpacing Codeium.
  • Tab suggestions feel smart enough to replace typing boilerplate by hand.
  • Neovim tab completion works better than Copilot outside VS Code.
  • The free version delivers solid inline completion with no API key needed.

Cons

  • The product was sunset on November 30, 2025, after an acquisition ended its development.
  • The extension can get stuck initializing and fail to work even on a single Python file.
  • JetBrains plugins broke and needed a manual Java file edit after every IDE update.
  • Rust suggestions came out as lightning-fast garbage, enough to drive a switch back to Copilot.
  • Always-on suggestions make learning a new programming language stressful.
