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

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits

Valkey

  • Younger project, so its track record is short even though the codebase is not
  • Divergence from Redis grows over time, so compatibility is strongest near the fork point and weakens as both evolve
  • Ecosystem tooling and documentation still frequently assume Redis, leaving translation work
