The code freeze tool to block merging and deployments

Merge Freeze is a Github app that allows dev teams to block merging at certain times of the week or during one-off situations.


One-off freezes

Anyone in your team can temporarily block merging.

Recurring freezes

Create a weekly schedule of merge freezes so your team can only merge during certain hours.

Deployments API

Access the merge freeze status from deployment scripts to block those too!

Slack app

Freeze or unfreeze your protected branch with a simple /mergefreeze command.

Slack app

The Slack app gives you a /mergefreeze command that, when called, will show you the current status of your protected branch(es) and a big shiny button to either freeze or unfreeze it.

It will also send your team a notification when someone implements a merge freeze, very handy as an extra reminder that everyone should stop merging. You can configure which channel these notifications should go to.

How do I install it?
1. Sign in through Github

We use Github to identify users since we need to access the Github API to see which of their repositories have the app installed.

2. Install the Github app

The Github app needs to be installed on at least one repository in order for it to be useful.

3. Add a protected branch

Pick a branch in your repository that you’d like to protect with Merge Freeze (usually master).

4. Link the protected branch to Slack

Click the “Add to Slack” button in the “Slack integration” panel of your protected branch. Once you’ve added the app to your Slack workspace you will be prompted to pick a channel for the notifications to be sent to.
