Mergify vs Graphite
Graphite and Mergify often show up in the same evaluation, even though they solve different problems. Here's an honest comparison.
The short answer
Graphite is a code review tool built around stacked diffs and AI review. Mergify is a merge platform with a queue, CI Insights, Test Insights, and Merge Protections. Mergify Stacks adds the stacking workflow on top: free and open source, included in every plan.

Used by platform teams at
From fast-moving startups to well-known enterprises
"Mergify gave us a merge queue that behaves predictably under heavy load. Reliability is everything, and Mergify made stability a solved problem."
Rushin Shah, Sr. Manager DevInfra
"The merge queue is a huge value from Mergify: it keeps our main stable and allows us to merge quickly with confidence."
Minh Tran, Platform Engineer
"You get the benefits of Mergify immediately. There is no competitor doing stuff like this."
Florian Berchtold, Software Engineer
"Since adopting Mergify, our code quality has skyrocketed. We've drastically reduced post-deployment bugs."
Bálint Bartha, Senior Platform Engineer
"We transitioned from manual chaos to over 20 safe deploys per day. Mergify is becoming a critical part of our delivery function."
Chris Irving, Engineering Manager
"We basically turned GitHub into an autonomous system. Mergify runs the entire choreography for us."
Fabien Marty, Senior Staff Software Engineer
"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."
Ben Holtzman, Senior Design Enablement Engineer
"Before Mergify, we spent too much time manually coordinating merges. Now everything flows automatically."
Nicolas Beaussart-Hatchuel, Senior Staff Software Engineer
"Mergify was the best fit. It saved a couple of hours per engineer per month and resolved our bottleneck with the merge queue."
Tomas Nekolny, Engineering Manager
"The support on Slack is really good, reactive and transparent. We have other partners where problems feel less transparent. With Mergify, it's fluid."
Clément Danjou, VP Blockchain
What each tool does best
The two products lean in different directions.
Graphite is great for
- Stacked diffs as the daily review workflow
- AI-assisted review on every PR
- Fast review loops where each commit becomes its own focused review
- Teams already running Graphite's CLI as part of their day-to-day
Mergify is great for
- Keeping main green at scale with a real merge queue
- Monorepos with scope-aware parallel queues
- Cutting CI cost via batching and two-step pipelines
- Flaky test detection and quarantine without a separate product
- Merge freezes and PR dependencies for governance
- Replacing Graphite for stacking too (Mergify Stacks ships in every plan)
Stacks without a second vendor
Mergify Stacks splits feature branches into atomic PRs from the Mergify CLI. It's free and open source, and it ships in every Mergify plan. The workflow shape matches what Graphite users already know.
Stacks merge through the same queue you already use. The CI batching and two-step pipeline logic apply to stacked PRs too. If your team only adopted Graphite for the stacking workflow, Mergify Stacks gives you that workflow inside the same platform.

FAQ
Should I switch from Graphite to Mergify?
Depends on what you adopted Graphite for. If you adopted Graphite for stacking, Mergify Stacks gives you the same workflow free and open source, with the merge queue underneath. If you adopted Graphite for AI code review, that's a different product and Mergify doesn't replace it.
Is Mergify Stacks the same as Graphite Stacks?
Same workflow shape, with stacks that merge through the same queue you already use. Mergify Stacks is free and open source, included in every Mergify plan. See the detailed Stacks vs Graphite comparison.
Does Graphite have a merge queue?
Graphite has shipped a merge queue feature, but it's limited compared to a dedicated queue product. Most teams running Graphite for review still bring a real merge queue underneath for batching, two-step CI, monorepo scope-awareness, and fast-forward merge.
How does pricing compare?
Graphite charges per user (around $20/user/month, around $40 with the merge queue add-on). Mergify charges per active contributor: anyone who acts on a PR in a 30-day sliding window, prorated to the day. A 30-engineer team where 15 people merge in a given month: $600 on Graphite (or $1,200 with queue), $315 on Mergify Max. See pricing.
Will switching to Mergify Stacks break my existing PRs?
No. The Mergify CLI works on plain git branches and standard rebase. Nothing about your repo state needs to change before you start stacking with Mergify.
Do Graphite users typically also adopt Mergify?
Yes, especially as teams grow past simple branch-protection merging. Graphite handles the review side well, and once broken-main incidents start adding up, you want a queue underneath. Mergify is the typical answer for that layer.
