No review-workflow replacement required
ShipCheck can sit on top of the GitHub workflow your team already uses instead of making a new PR interface, stack model, or merge queue the center of adoption.
BetaShipCheck vs. Graphite
Move pull requests faster.Or remember what they must not break.
Graphite is an end-to-end code-review workflow built around AI review, stacked pull requests, its PR interface, merge queues, inboxes, chat, CLI tooling, and developer velocity. ShipCheck does not try to replace that workflow. It adds a persistent behavioral verification layer to the repository you already use.
Comparison based on publicly documented product capabilities as of September 2026. Features may change.
The difference
Graphite optimizes how changes move through review. ShipCheck focuses on what those changes must preserve and what proof is required before they move. Behavior Contracts, evidence policy, risk-aware verdicts, Behavioral Diff, and Behavior History make ShipCheck a behavioral-governance layer rather than another PR interface or merge workflow.
Why ShipCheck
Review the change.Remember the behavior.
ShipCheck is not trying to win by producing more comments. Its advantage is retaining important behavioral knowledge after the pull request is over and bringing it back when the next change arrives.
Behavior survives individual PRs
Important expectations become durable repository memory rather than existing only inside the review of one change.
Regression history is first-class
Behavior History records how an expectation changes across many pull requests rather than optimizing only the flow of those pull requests.
Historical origin explains old safeguards
ShipCheck can recover where a behavior came from so a later cleanup can distinguish dead code from a safeguard introduced for a real reason.
Graphite
What it is built around.
Stacked pull requests
Graphite lets teams build and review chains of dependent, smaller PRs.
Integrated merge workflow
Its stack-aware merge queue, PR interface, inbox, CLI, and notifications optimize review throughput.
AI review and chat
Graphite automatically reviews PRs and provides suggested fixes and conversational assistance inside its review experience.
The ShipCheck advantage
The repository should remember why behavior matters.
A reviewer can understand the current code. ShipCheck goes further by retaining the important expectations that understanding reveals and checking them again later.
01
ShipCheck does not need to own the workflow to protect the code.
It is designed as a focused verification layer: connect the repository, retain important behavioral expectations, and evaluate future changes without replacing your PR UI or merge mechanics.
02
ShipCheck optimizes for behavioral continuity, not PR throughput.
The central question is not how quickly a PR moved through review. It is whether a safeguard, contract, authorization rule, validation behavior, or other invariant silently changed.
03
Repository memory remains useful through workflow changes.
Behavior Contracts and their immutable history stay attached to the software even if the team later changes editors, coding agents, reviewers, branching conventions, or review tooling.

Side by side
What each product actually stores and verifies.
This comparison avoids treating every kind of “memory,” rule, history, or context as equivalent. ShipCheck's strongest distinction is explicit behavioral state carried across repository history.

The ShipCheck thesis
A repository should not need to rediscover the same critical behavior every time someone opens another pull request.
Your PR workflow moves changes. ShipCheck remembers what those changes must preserve.
Add behavioral verification without turning repository memory into another workflow migration.
