The short version

  • Each has a real cost: Rust compile times significantly longer than languages like Go or C; Semgrep free tier caps out at 10 contributors and 10 repositories.
  • They diverge on capability: Rust covers Memory safety, Semgrep covers Static code scanning.
  • Prices and features above were last checked on 30 August 2026.

  • Prioritizing findings with AI-assisted triagenot Rust

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Rust

  • Compile times significantly longer than languages like Go or C
  • Smaller ecosystem of libraries and frameworks compared to Python or JavaScript
  • Community still smaller than mainstream languages, reducing available third-party resources

Semgrep

  • Free tier caps out at 10 contributors and 10 repositories.
  • Secrets scanning is priced as a separate module ($15/contributor) from Code and Supply Chain.
  • Self-managed repositories and custom CI/CD require the Enterprise tier.
  • AI credits are limited per tier and additional usage requires upgrading.
