Trunk

Trunk is a continuous integration reliability platform that helps engineering teams eliminate flaky tests and merge bottlenecks, keeping main branches green and deployment pipelines fast. Trusted by Faire, Brex, Gusto, Zillow, Cockroach Labs, Google, Retool, BetterUp, Metabase, AgencyAnalytics, and Glydways, the platform addresses the core problem of flaky tests that waste CI compute and erode developer trust in test suites. The flaky test detection engine works with any language, any test runner, and any CI provider, automatically identifying tests that pass and fail intermittently by analyzing historical run data and comparing outcomes across multiple executions of the same code commit. When a flaky test is detected, Trunk automatically quarantines it from the main test suite while continuing to collect stack traces and failure metadata, so that developers can investigate at their own pace without blocking the pipeline. PR-level test summaries integrate with Slack and Linear for real-time notification of flakes affecting individual pull requests. The merge queue product upgrades GitHub native merge queues with intelligent batching that runs up to 100 pull requests in parallel, anti-flake protection that skips known flaky tests during merge verification, automatic bisection that identifies which PR introduced a failure when multiple PRs are tested together, and parallel queue support for large teams. Faire reduced merge queue time from 30 minutes to 2 minutes using Trunk intelligent batching. The platform supports Bring Your Own Cloud deployment for data residency requirements.
