Trunk

Trunk is a CI acceleration platform that targets teams who ship software quickly. It detects flaky tests, quarantines them, and enables parallel merge queues to improve throughput. The tool supports any language, any test runner, and any CI provider, and it integrates with existing workflows to reduce wasted CI time.

Trunk’s flaky tests capability analyzes failures, quarantines flaky tests, and provides test summaries in PRs. It surfaces failure modes through stack traces, supports webhook integrations, and connects to ticketing tools like Linear or Jira to auto-create or update tickets. The platform also offers AI-powered failure analysis to identify duplicate failures and provide summaries of what went wrong.

The merge queue feature runs tests for non-overlapping PR targets in parallel, batches PRs into a single CI run when needed, and uses auto-bisection to isolate culprits when a batch fails. Anti-flake protection helps prevent flaky failures from stalling the queue, while a backstop ensures all commits are tested. Per-job verdicts determine whether a job runs or is skipped based on changes and historical behavior.

It notes a security and compliance posture (SOC 2 Type II, TLS, data encryption, and more) and describes deployment options (on-premises or private cloud), plus support details and access controls.

Use cases

• Teams with high PR volume seeking to keep main green while moving fast
• Organizations needing parallelism for large monorepos
