Statement: CI adoption among open source projects is substantially higher than 40% — the figure is outdated or based on samples that include abandoned/trivial repositories that deflate the rate.
Supporting Evidence Would Show¶
- Recent studies (2024-2025) showing CI adoption rates of 50% or higher across GitHub repositories.
- Evidence that GitHub Actions' zero-friction integration has significantly increased CI adoption since earlier Travis CI-era studies.
- Studies that filter for actively maintained projects showing adoption rates well above 40%.
- GitHub's own Octoverse data showing majority CI usage.
Eliminating Evidence Would Show¶
- Studies of actively maintained projects still showing ~40% or lower CI adoption.
- Evidence that GitHub Actions adoption has plateaued without substantially increasing the overall CI adoption rate.
- Multiple recent (2024+) studies confirming the ~40% figure.
