In their own words
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.
TeamCity
TeamCity is a continuous integration and delivery server for automating software builds, tests and delivery. Build chains organize pipelines into reusable steps that can run in parallel and share results across configurations. Build caching, artifact dependencies and incremental builds reduce repeated work. TeamCity can test changes before commit and commit them automatically if they pass, while test-history analysis can flag inconsistent results. Pipeline settings can be kept in Kotlin DSL, XML or YAML, or generated from the interface. Supported version control systems include Git, Perforce, Mercurial, Subversion and CVS, with integrations for GitHub, GitLab, Bitbucket and Azure DevOps. Listed infrastructure integrations include AWS, Kubernetes, Google Cloud Platform, Azure Resource Manager and VMware vSphere. TeamCity is available on-premises or in the cloud. The Professional on-premises plan is free forever and includes three build agents, 100 build configurations and 10 pipelines. Cloud costs $15.00 per committer, per month, with a three-committer minimum; its trial is 14 days, while the on-premises Enterprise trial lasts 30 days.
