Stacked PR review
Breaks a change set into multiple stacked pull requests so related work can be reviewed in dependency order.
Alchemize
Alchemize is an AI code review platform that helps teams review changes in stacked pull requests with dependency-aware context and agent-based testing. It syncs review activity with GitHub and keeps GitHub as the source of truth.
What Alchemize does
Alchemize is an AI code review platform for teams that need to review larger, more complex changes with more context. It breaks code changes into stacked pull requests, arranges related work into dependency-aware review units, and presents them in a deterministic order that is easier for people to follow.
The product also adds automated testing through agents and keeps review activity synchronized with GitHub. Its stated workflow is designed to help teams understand agentic code, review intent behind specific lines, and recover safely when GitHub updates are interrupted.
Core capabilities
Dependency-aware review graph
Builds reviewable units from the change graph and stable execution plan before creating pull requests.
Safe GitHub update coordination
Serializes GitHub mutations and uses idempotency keys so interrupted updates can be retried without duplicating work.
Prompt-to-code context
Connects each line of change to the prompt behind it, helping reviewers separate author intent from agent output.
Agent-based test execution
Reads the diff and runs tests through agents to catch bugs automatically.
Two-way GitHub sync
Keeps changes, comments, and review status synced between Alchemize and GitHub.
Common ways teams can use Alchemize
Review large multi-file changes
Use Alchemize when a change spans many files and needs to be split into smaller, reviewable units that preserve dependency order.
Review agentic code with more context
Use it for agent-generated code that needs extra context so reviewers can tell intended behavior from model assumptions.
Recover interrupted review workflows
Use it when a PR update is interrupted and the team needs a safe way to retry GitHub mutations without duplicating work.
Run automated tests against the diff
Use it to automate test coverage on diffs that may hide bugs in unrelated parts of the stack.
