In their own words
BuildPulse
BuildPulse is a CI and test-health platform for tracking flaky tests, coverage, build activity, and engineering metrics. It detects flaky tests across branches and pull requests, ranks them by engineering time affected, and lets teams quarantine them. Detection can use JUnit XML from an existing test runner with one workflow step, without annotations or an SDK. Coverage tracking accepts LCOV and Cobertura XML and shows trends by branch and file. Repository views include pass rate, test volume, build duration, flaky-test disruption, and recent builds across 7-, 30-, and 90-day periods. BuildPulse also offers CI runners described as replacements for hosted runners from GitHub Actions, Semaphore, and CircleCI, along with AI code review. Connections include GitHub, Bitbucket, Jira, and Slack. BuildPulse says it processes test results, coverage reports, and CI metadata rather than keeping full source-code copies. Pricing starts at $99 a month for Startup; there is no free plan, though a 14-day trial is listed.
Captain
Captain is an open-source command-line tool for finding flaky tests and managing test execution. It measures test reliability, can retry failed tests, and can quarantine flaky ones to unblock builds. By tracking test runtimes, it balances files across parallel jobs. Framework integrations include xUnit, ExUnit, Ginkgo, go test, Bun, Cucumber, Cypress, Jest, Karma, Mocha, Playwright, TestCafe, Vitest, PHPUnit, pytest, unittest, minitest, and RSpec. CI integrations listed include RWX, GitHub Actions, CircleCI, Buildkite, and GitLab. Framework results can be reviewed in a web interface for managing flakes, retries, quarantine, and suite partitioning. Feature availability varies: xUnit does not include partitioning, and Karma does not list retries or partitioning. The free OSS plan includes file-based configuration, partitioning, flaky-test tracking and quarantine, and retries. Pro costs what you agree with the maker, billed per million test results uploaded, and adds analytics on flaky tests and performance trends with 90-day retention.
