Where each one falls short

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

Harness

  • Essentials plan caps users at 500, organizations at 1, custom dashboards at 5 and concurrent CI pipeline executions at 60, all unlimited only on Enterprise
  • Pipeline history is limited to 6 months on the Essentials plan; extending to 25 months requires an Enterprise add-on
  • Enterprise plan pricing is quote only, reached by contacting sales rather than a published rate

Yarn

  • Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
  • Smaller ecosystem and community compared to npm, though still substantial
