Coverage analysis inside every pull request
OtterWise automatically adds detailed coverage analysis to your GitHub pull requests, helping your team maintain high code quality standards.
OtterWise's automated pull request comments provide immediate visibility into how code changes affect your test coverage. Each comment includes:
- Overall coverage percentage and change from base branch
- Patch coverage (percentage of changed lines covered by tests)
- Detailed metrics including files with reduced coverage
- Links to the full coverage report in OtterWise
Comments are automatically updated when new commits are pushed, keeping the discussion focused while ensuring your team always has the latest coverage data.
No configuration required. Just enable the feature in your repository settings and OtterWise will start adding valuable insights to your PRs.
No credit card required for public repos.
Privacy by default
We never access your source. We only store coverage metrics and the minimal service data needed to run OtterWise. Read about our code privacy efforts.
Invite your entire team
All plans (including free) offer unlimited collaborators at no extra charge. You can invite your entire engineering department, designers, PMs, and stakeholders.
Track progress anywhere
Watch coverage move over time in the dashboard, or pull the same numbers into your own with the API.
Onboarding assistance
All paid plans include priority chat support, and we can help you get running even if you have no CI pipeline yet.
Tailored to your workflow
Configure which files to ignore, when to fail CI, how coverage is calculated, and more. It bends to your setup, not the other way around.
Surface the riskiest code
Per-line coverage, type coverage, and CRAP scores point you at the code most likely to break, so you test what matters first.
See exactly what your tests miss.
Free for public repos. Set up in 5 minutes. No credit card required.
Coverage trends
Track trends, spot wins, find gaps
See how coverage moves across every branch: who's pushing it up, where code is slipping through untested, and which trends to act on before they become problems.
#123 Add new feature for import & export of user data
Status checks
Block bad code before it ships
Status checks automatically fail PRs when coverage drops or complexity spikes. Set your own quality thresholds and let automation enforce them. No more “looks good to me” merges that introduce untested code.
