Intro

What is Trunk?

Trunk (also known as Trunk.io) is an AI-powered DevOps platform and CI reliability engine built to eliminate flaky tests and slow CI pipelines. Backed by prominent investors like Trunk A16Z, the Trunk startup offers an AI DevOps assistant that integrates seamlessly into tools like GitHub, Slack, and code editors. Developers use the Trunk CLI, trunk check, and trunk fmt to automate code quality checks, while features like the advanced merge queue prevent broken builds from ever hitting the mainline branch.
