“Merge Freeze has been very popular with the Immersive Labs engineering team!”
Mike Babb
Engineering Manager, Immersive Labs
“Merge freeze was a pure improvement over our previous process. Mostly ignored "Master lock" slack messages are now enforced and auditable, having become an actual process rather than a convention. The slack integration was the big selling point for us.”
Alec Rosenbaum
Staff Backend Engineer
“Merge Freeze has been an essential tool in an overhaul of the merge processes for our rapid release projects, and its Slack integration made it super easy for our engineers at Wave to adopt.”
Dylan Pomeroy
Senior Software Engineer, Wave
“It's very useful in controlling our deployment pipeline - 5/5!”
Tom Thorne
CTO, PepperHQ
“Mergefreeze has become second nature for us. We don't think about it, it is there and just works. It's at the sweet spot of between being visible and invisible: visible enough that we know we use it. Invisible enough that it doesn't get in the way.”
Xavier Cambar
Engineering Manager, CLARK
“Merge freeze is a great tool. It helps our team of over 80 engineers keep in sync. It makes the system more sane and lets us manage our release better. We are also in the process of integrating with your APIs through our internal app to manage everything better. We are an open source platform and we really appreciate the service you are providing.”
Somangshu Goswami
Engineering Manager, Appsmith
“Having to gate our pipeline is a pain in the ass, but at least MergeFreeze makes it simple and it just works™.”
Juan Lulkin
Lead Architect, Choco
“Merge Freeze is straightforward and simple to use, but such an impact! The initial configuration took just a few minutes. It turned a monotonous, repetitive task for multiple repos into one simple click with the batch option. My team is loving it. The Merge Freeze team was very responsive to requests and questions - they exceed expectations at every turn!”
Margaret Medon
Manager of Product Release, nCino
“Merge Freeze has massively improved communication around the Content Management System's release process, setting clear expectations across dozens of engineers in multiple groups. It's been a great enhancement to our GitHub workflows!”
Jon Peck
Director of Engineering, Insider
“Worth Every Penny. Merge Freeze is such a simple tool but it has streamlined our release cycle and prevented last minute code changes that were delaying our code releases. What we love most is that it is really simple to unfreeze a single repo or single PR that needs to be pushed but still creates visibility and accountability to the team member that did it. 5 out of five stars.”
Ryan Sherman
VP of Product, Allbound
“Merge freeze has been great for us. I really like the product and it provides a lot of value.”
Corbin Phelps
Principal Software Engineer, ObservIQ
