Mergepatrol vs Graphite's merge queue

2026-10-31

Graphite is a code review tool built around stacked pull requests, and its merge queue is one part of it. Mergepatrol is a merge queue on its own: it works with GitHub’s pull requests as they are, including stacks made with gh stack. Checked against Graphite’s docs and pricing on 31 October 2026.

At a glance

	Graphite merge queue	Mergepatrol
Price	On the Team plan ($40 a seat a month, billed annually) as a “Basic” queue, “Advanced” on Enterprise; not listed on Hobby or Starter	Public repos free; private repos $15 a seat a month after a 14-day trial; self-hosted free
What you adopt	Graphite’s review app, and its `gt` CLI for stacks	A GitHub App and a config file; review stays on GitHub
Stacks	Stack-aware; a queued stack is validated in parallel	A `gh stack` stack is one queue item, merged all at once with GitHub’s asynchronous merge
Batching	In private beta; a failed batch is bisected or every PR isolated	On by default; a failed batch is split in half down to the PR that broke it
A PR that conflicts	Rebased automatically, but a real conflict goes back to you to `gt restack` and re-queue	A plain `git rebase` first, then an agent on a real conflict, checked by your `verify` commands
A required check that fails	Back to its author	An agent commits a fix on the PR, up to `fix_ci.attempts` times
Works alongside GitHub’s merge queue	No: GitHub’s queue must be off	No: one queue per branch
Source	Proprietary SaaS	Apache-2.0, self-hostable

Where Graphite is the better fit

Your team already reviews in Graphite and stacks with gt. The queue is part of the same workflow, and restacking is handled by the same tool.
You want a review product, not only a queue. Graphite’s review and stacking UI come with the plan that includes the queue.

Where Mergepatrol is the better fit

You review on GitHub and stack with gh stack, or do not stack at all. Nothing changes about how people open and review pull requests: they add a label.
Conflicts that would send a stack back to its author. The agent resolves them in place and the stack keeps its place. See How to merge stacked pull requests.
Batching you can use today on any plan, with bisection by default.
Price per seat. $15 a month for private repos, free for public ones, against a queue that starts at Graphite’s $40 Team plan.

FAQ

Do I need the Graphite CLI to use its merge queue? You can queue from Graphite’s web app, but its docs note that automatic restacking does not work when merging from GitHub.

Does Mergepatrol need gh stack? Only for stacks. A pull request stacked by hand on another PR’s branch is held; a gh stack stack queues as one item. Plain pull requests need nothing.
