Where each one falls short

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

Bazel

  • Steep learning curve for developers unfamiliar with build systems
  • Initial setup complexity; requires BUILD files and Bazel configuration
  • Verbose error messages can be difficult to debug for new users
  • Smaller community and fewer third-party integrations vs enterprise tools

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.
