The verdict
Mergify Stacks appears in 2 AI-ranked categories.
One local branch, one commit per reviewable PR, OSS CLI, no second review app, and the same merge queue handles stacked and unstacked PRs. Lower local-branch chaos than Graphite’s branch-per-layer model; good fit if Mergify is already the merge control plane.
Where Mergify Stacks falls short, per the models
- Grok Weaker in-stack editing (split/fold/absorb) than gt and less of a review product — not for teams that live in stack surgery all day or that do not already want Mergify’s queue.

One-local-branch Change-Id model (no branch graph to manage) that stays pure Git + GitHub PRs; free/open-source stacking layer that pairs cleanly with their mature batching merge queue and monorepo scope rules; assumption is teams want minimal workflow change
Where Mergify Stacks falls short, per the models
- Grok Weaker first-class stack visualization and mid-stack rewrite tools than dedicated stacking CLIs
