Code explainability for massive diffs.
Understand a thousand-line diff in minutes with the first review surface for agentic code.
The comprehension gap is widening.
More people and agents are creating code. PRs are also getting larger. Reviewers can no longer reconstruct intent, behavior, and blast radius from every diff.
Agent outputHuman comprehension
The diff shows what changed. We show what it means.
Git platforms make large diffs confusing. Change Stack gives you the context you need to understand the change.
Intent
What the PR is trying to accomplish with context from issues and more.
Risk
The nature and level of the risk the PR poses.
Dependencies
Which files and services are implicated in this change.
Behavior
How the change affects the application and user behavior.
Any uncertainties
What our agents can’t deduce from the diff.
Visualize the impact across layers.
Change Stack gives you the walkthrough a senior engineer would give.
Group related work so reviewers can move through the change by intent instead of file order.
Break cohorts into a sequence anchored to specific line ranges.
Create sequence, state-machine, or entity-relationship diagrams where the diff needs them.
Understand how the change reaches across files and services.
See the risks and the parts of the diff driving them.
Illustrative demo: the Change Stack screen becomes the Review Change Stack button in a GitHub comment. A Triage PR card provides another Change Stack entry point with an always-visible button.
Understand the change and ship with confidence.
Approve with context, not guesswork.
Stop rubberstamping large PRs or delaying them until you have time to understand them.
Ship faster.
Understand quickly so you can fast-track low-risk changes or conduct a deeper review.
Deal with the overwhelm.
Reviewers have to understand more changes than ever. Get the context you need to review the diff.
Reduce risk from lack of understanding.
Not understanding the diff increases the chance that something will slip through.
