Analysis summary

Supermaven is a community-maintained IDE extension from Supermaven. Anomity scores its risk at 50 out of 100 (medium).

Supermaven is an AI code completion extension that is built around a custom model designed for very low latency and a context window large enough to feed entire repositories. It targets VS Code, JetBrains, Neovim, and a handful of other editors, and is one of the few extensions in the autocomplete category that markets sub-100ms response times as a primary differentiator.

Its declared capabilities are deliberately narrow for a category that often over-asks. The extension reads files in the open workspace to assemble context for completions, makes outbound network requests to Supermaven's hosted completion service, and reads the locally stored Supermaven credential. It does not request filesystem write access — the IDE handles insertion of accepted suggestions — and does not execute shell commands.

Supermaven is community trust because it is published by an independent vendor rather than a marketplace platform. The credential plus outbound network pairing is the only one that lights up Anomity's risk signals, and it does not match any dangerous combination. The residual concern is the standard one for hosted-completion products: source code from your workspace is transmitted to the vendor on every request, so teams under confidentiality controls should validate Supermaven's data-handling terms before adopting it broadly.

Why this entry scored 50 out of 100

This profile starts at the catalog's neutral base of 50. Because the entry is community-maintained, trust adjusts the score by -10. Declared high-risk capabilities add +10 (capped at +30). It matches no dangerous capability combinations. The clamped result is 50, placing it in the medium band.

Capabilities

Every capability the entry declares, with the security implication of each.

  • filesystem:read Filesystem read
    Can read files on the host system. Used for context, indexing, or analysis.
  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.
  • credentials:access Credentials access
    Reads provider API keys, OAuth tokens, or other secrets from the host keychain or environment.
