Stop breaking main
Two PRs pass CI. Both merge. Main breaks. Sound familiar?
Mergify's merge queue tests every PR against the actual state of your main branch before it merges.
Broken builds never reach production.
Every PR tested against reality,
not a stale snapshot
Why PRs that pass CI still break main
When two PRs are developed in parallel, each passes CI against its own base. But when both merge, their combined changes can conflict, not just textually but semantically. Mergify's merge queue catches this by updating each PR to the latest main before running CI.
Up-to-date pull requests & test run
Every PR is rebased on the latest main and retested before it merges. No stale bases, no surprises.
Intelligent retesting
If a PR would break main, it gets caught before it merges. Not after.
Conflict resolution
When PRs conflict, Mergify picks the right one to merge and notifies the author of the other. No manual triage needed.
Want to see how it works for your team?
5-minute setup. No migration needed.
Early on, as the team, tests, and CI complexity grew, it was quite clear that we needed an automated tool to resolve bottlenecks. Our team loves the way Mergify solved our growing pains.

Stop paying for CI runs that don't matter
Running CI on every pull request regardless of merge readiness wastes compute and money.
Batch processing
Group PRs by scope and test them together in a single CI run. If a batch fails, bisect-on-failure finds the culprit automatically.
Two-step CI
Run fast checks on every push. Save the full test suite for PRs that are actually ready to merge. Less CI waste, faster feedback.
Mergify is a no-brainer. If you want to have your main branch always working then you have to introduce some merge queue functionality.

Already using GitHub's merge queue?
See exactly where it falls short and what Mergify adds: batching, priorities, two-step CI, monorepo scoping, and more.
Built for pipelines that take hours, not minutes
Firmware builds, OS validation, hardware-in-the-loop testing. When CI runs are expensive, every wasted minute compounds.
Long test cycles
Multi-hour pipelines make every failure expensive. Two-step CI runs lightweight checks first.
Flaky tests at scale
One intermittent failure can stall dozens of engineers. Auto-retry and quarantine keep the queue moving.
CI costs spiral
Big jobs plus reruns multiply your bill. Batching tests PRs together and bisects on failure to avoid waste.
Rigid queues
No two-step validation, no smart batching, no priority lanes. Mergify gives you all of these out of the box.
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.
