What it does
Trunk is an all-in-one tool for scalably checking, formatting, and monitoring code. This will allow your engineers to stay focused on your core business and ship code faster. Trunk installs in minutes and runs in your IDE, CLI, or on your CI platform.
The CI acceleration platform that detects flaky tests and speeds up merges. Used by Brex, Ramp, Supabase, and Zillow.
Speed up CI by eliminating test re-runs while continuing to collect stack trace info on failures. Stay on top of flakes with test summaries in PRs and integrations with tools like Slack and Linear. Spot duplicate failures and get AI summaries of what went wrong. Stop main from turning red. Stop CI costs from spiraling. Stop waiting in a serial queue. Failed PRs stay in queue while downstream PRs test. If a later PR passes, both are merged. Batch up to 100 PRs in one run. When a batch fails, auto-bisection isolates the culprit - no manual debugging. Create parallel lanes for non-overlapping changes. Hotfixes jump the line without cascade rebuilds. We would have never known how many flaky…from trunk.io

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
