See uncovered code right in GitHub
OtterWise highlights uncovered code directly in GitHub's interface, making it easy to identify areas that need additional test coverage.
Line annotations provide immediate visual feedback about coverage gaps in your pull requests. When enabled, OtterWise will:
- Analyze which lines of code are not covered by tests in your changes
- Group consecutive uncovered lines together for better readability
- Add annotations to these line groups in GitHub's pull request and commit views
- Create a "neutral" status check that provides a summary of uncovered areas
The annotations appear as informative notices in the GitHub interface, allowing your team to see coverage gaps without disrupting the review process. Since they use a "neutral" conclusion rather than "failure", they won't block CI workflows or prevent merging pull requests.
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.

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.
