Where each one falls short

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

Pants Build

  • Smaller community compared to Bazel with fewer third-party tool integrations
  • Python plugin API steeper learning curve for custom build rules

  • Fewer integration examples for enterprise CI/CD platforms

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.
