How We Do It
We explain how we work at Mergify, design, and develop our products.
Freezing your GitHub repository merges
Freezing your GitHub repository could mean a lot of things. In that case, I'm not talking about putting it on ice or sending it to GitHub's Artic Code Vault. No, that's not the point here. As controlling the merge flow becomes increasingly important, many
4 Reflexions on the design of the Merge Queue Freeze
Merge queues are at the center of the value offered by Mergify. The freeze feature we announced [https://blog.mergify.com/announcing-merge-queue-freezes/] a few days ago gives our merge queues a whole new range of possible use cases.

Handling unexpected third party API changes
As you may guess, Mergify relies a lot on third-party APIs like the Stripe API [https://stripe.com/docs/api] or the GitHub API [https://docs.github.com/en/rest] and their behavior. Like any third-party service, we need to deal with many things to ensure our integration never breaks.

Speculative Checks and Batch: Under the Hood

Behind the scene of time-based conditions
Last month, we announced [https://blog.mergify.com/announcing-time-based-conditions/] a new set of conditions for Mergify rules based on time. You can now use a time and date and compare pull request attributes to dates and times. We had the idea for this feature since the beginning of Mergify, but
(Un)signed commits: how we found a (non) security bug in GitHub
When you build an entire software around someone else API, you tend to know everything about it. We made Mergify [https://mergify.io] on top of GitHub API, and it's hard to describe how well we understand its API. From its fabulous and beloved features to its most
Why Deciding Fast Is a Winning Strategy
If you're a video gamer and think you're not up to the task of launching a startup, think twice. At Mergify, we've been heavy video game players for the last couple of decades, and we think differently. Here's one thing we learned
A React Crisp Component
Some time ago, Mergify decided to move his chat widget from Drift [https://drift.com/] to Crisp [https://crisp.chat]. What's this, you say? You know, this is the little button at the bottom right of your screen where you can engage with our fantastic support team! Integration
Why we switched from Notion to Linear
A few months ago, we blogged about how we handle our roadmap [https://blog.mergify.io/how-we-handle-our-roadmap-for-mergify/] at Mergify. The tool we mentioned using was Notion [https://notion.so], an all-in-one tool that can adapt to many usage. Notion is a useful tool, and we were able to adapt it
Handling 300k GitHub events per day
As Mergify is a pull request automation tool, to execute actions on your pull requests, it needs to be aware of any change done on them. To get notified of any mutation, Mergify relies on the GitHub App webhook mechanism. That means that on any modification done to a pull
How we handle our roadmap for Mergify
Whatever you’re building — a company, a product, or a house — a time comes where you need planning. Pushing random buttons to move forward does not work anymore. You need to take a step back to think about what the optimal move to do next. This arrangement of your future
