"Mergify gave us a merge queue that behaves predictably under heavy load. Reliability is everything, and Mergify made stability a solved problem."

Rushin Shah, Sr. Manager DevInfra

"The merge queue is a huge value from Mergify: it keeps our main stable and allows us to merge quickly with confidence."

Minh Tran, Platform Engineer

"You get the benefits of Mergify immediately. There is no competitor doing stuff like this."

Florian Berchtold, Software Engineer

"Since adopting Mergify, our code quality has skyrocketed. We've drastically reduced post-deployment bugs."

Bálint Bartha, Senior Platform Engineer

"We transitioned from manual chaos to over 20 safe deploys per day. Mergify is becoming a critical part of our delivery function."

Chris Irving, Engineering Manager

"We basically turned GitHub into an autonomous system. Mergify runs the entire choreography for us."

Fabien Marty, Senior Staff Software Engineer

"With dozens of engineers and long-running CI jobs, Mergify turned what used to be a daily bottleneck into a background process. Our teams focus on hardware, not merge logistics."

Ben Holtzman, Senior Design Enablement Engineer

"Before Mergify, we spent too much time manually coordinating merges. Now everything flows automatically."

Nicolas Beaussart-Hatchuel, Senior Staff Software Engineer

"Mergify was the best fit. It saved a couple of hours per engineer per month and resolved our bottleneck with the merge queue."

Tomas Nekolny, Engineering Manager

"The support on Slack is really good, reactive and transparent. We have other partners where problems feel less transparent. With Mergify, it's fluid."

Clément Danjou, VP Blockchain

Migration guide

Bulldozer got us started, but as soon as we hit scale, our CI was constantly overloaded. We postponed but should have transitioned to Mergify earlier.

Jona Gistao

Senior Software Engineer at CloudRail

We previously used Bulldozer but with Mergify's Merge Queue we cut our CI runs by 40% and we got really good visibility into flaky tests.
