Merge Freeze is a Github and Slack app that allows teams to block merging and deployments at scheduled times or during one-off situations. Freezes can be triggered with a simple `/mergefreeze` command in Slack, or through the web control panel.
Stop team members from merging and deploying. For one-off situations or at set times.
Merge Freeze is a GitHub app that helps your team block PR merging during critical times for safer deployments. Schedule recurring freezes so you can’t merge at certain times of the day, week or month. Access the current Merge Freeze status of your repository or trigger a freeze using our API. “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.

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…
