Hold the merge
until the prerequisites
land.
PRereq reads depends on #88 from your pull requests and posts a check that won't go green until every PR it needs has merged. Stacked work ships in the right order — on its own.
One click install · No credit card required
Four steps. Then it's just there.
The order matters, so the layout follows it — a single dependency line threaded through the whole flow.
- 01
Write the dependency
Drop “depends on acme/db#88” in your PR description — cross-repo refs welcome. Say it however your team already talks: blocked by, requires, needs.
- 02
PRereq posts a check
The moment the PR opens, a required status check named prereq/dependencies appears alongside your build and tests.
- 03
The merge holds
While any prerequisite is still open, the check stays red and GitHub won’t let the pull request merge. No accidental out-of-order landings.
- 04
It clears itself
Merge the PRs it depends on and the check turns green on its own. No re-runs, no comments to type, no babysitting.
Small check. Strong guarantees.
Cross-repo dependencies
Depend on a PR in any other repository. Just state the repo name and PR number and PRereq will find it.
Cycle detection
If two PRs end up waiting on each other, PRereq names the loop instead of quietly deadlocking your merges.
Reads your words
No new syntax to learn, just tell PRereq how your team expresses dependencies.
Enforced, not advisory
PRereq is a status check. Add it to your required checks and the merge order becomes a rule, not a reminder.
One install, every repo
Install once on the organization. New repositories are picked up automatically.
Fair metering
You're only counted for checks that actually enforce a dependency. A pull request with no prerequisites is free.
Priced by enforced checks.
Every plan is unlimited repositories and unlimited people. The only meter is how many times a dependency actually holds a merge.
Stop merging things in the wrong order.
Install PRereq on your organization and the next dependent PR you open is protected. It takes about a minute.
