Captain
Columbus, Ohio, United States
What it is
Captain is an open-source command-line tool for tracking flaky tests and managing test execution. It measures test reliability, detects flaky tests, retries failures, and can quarantine flaky tests to help unblock builds. By tracking test runtimes, it balances test files across parallel jobs. Framework integrations can send results to a web interface, where teams can review flakes and manage retries, quarantine, and suite partitioning. Documented framework support includes Jest, Playwright, Cypress, pytest, xUnit, RSpec, and others; listed CI integrations include RWX, GitHub Actions, CircleCI, Buildkite, and GitLab. Feature coverage varies by framework: xUnit does not include partitioning, while Karma does not list retry or partitioning support. The free OSS plan includes file-based configuration, partitioning, flaky-test tracking and quarantine, and retries. Captain Pro costs $10 per million test results uploaded and adds analytics on problematic flaky tests and test performance trends with 90-day retention. Enterprise pricing is custom. RWX says it is SOC 2 Type 2 compliant and that Drata tests its security and IT infrastructure daily.
For and against
For
- Detects flaky tests and measures test reliability
- Retries failures and quarantines flaky tests
- Balances test files across parallel jobs
- Free OSS plan includes tracking, retries, and partitioning
- Web interface supports test-result analysis
Against
- Feature availability varies by framework

The verdict
Captain combines test-flake management with parallel suite partitioning and a web interface for reviewing results. Check framework-specific feature coverage before relying on a particular retry or partitioning workflow.
Who it suits
Captain suits development teams that want to identify flaky tests, retry or quarantine them, and distribute test suites across parallel jobs. Teams should check which features their chosen framework integration supports.
