Trunk Launcher

Trunk provides a CI reliability platform that detects, quarantines, and eliminates flaky tests across any language, test runner, or CI provider. It automatically isolates unstable tests, records stack traces, and presents summaries in pull‑request views, helping teams keep their build status green and avoid merge bottlenecks. Integrated ticketing links to tools such as Linear or Jira, while webhook support enables custom notifications in Slack and other services.

The service also enhances GitHub merge queues with anti‑flake protection, preventing failing PRs from blocking subsequent changes and allowing later passes to trigger merges. Intelligent batching groups up to one hundred PRs per run, and when a batch fails the system auto‑bisects to pinpoint the offending change. Parallel queues create separate lanes for non‑overlapping modifications, letting urgent hotfixes bypass the normal flow without triggering cascade rebuilds.

Developers benefit from AI‑powered failure analysis that highlights duplicate failures and generates concise summaries of root causes. Test‑status history tracks when a test becomes flaky or broken, giving visibility into test health over time. The platform is positioned for teams using monorepos or large developer groups, aiming to reduce CI costs and accelerate shipping cycles.
