Trunk

Trunk is a specialized platform designed to solve two critical problems in software development: flaky tests that disrupt continuous integration pipelines and inefficient GitHub merge queues that slow down team productivity. The tool automatically detects, quarantines, and helps eliminate unreliable tests that sometimes pass and sometimes fail for no apparent reason. It works with any programming language, test runner, or CI provider, making it versatile for diverse development environments.

What makes Trunk stand out is its intelligent approach to both testing and merging workflows. For flaky tests, it uses AI-powered failure analysis to spot duplicate failures and provide smart summaries of what went wrong. The platform integrates directly with tools like Slack and Linear to keep teams informed, and can automatically create and update tickets when issues are detected. For merge queues, Trunk offers advanced features like anti-flake protection that keeps failed PRs in queue while downstream PRs continue testing, intelligent batching that can combine up to 100 PRs in a single run, and parallel queues for non-overlapping changes.

Development teams at fast-growing companies benefit most from Trunk, particularly those experiencing CI bottlenecks or spending significant time debugging test failures. Real-world use cases include reducing merge queue times from 30 minutes to just 2 minutes, automatically quarantining problematic tests without manual intervention, and providing clear dashboards that show which tests are impacting the organization most significantly. The platform helps engineering teams maintain velocity while ensuring code quality.
