For reviewers and engineering managers
Every pull request on its own URL
The pipeline stands up a full copy of your application for each pull request, built from that commit, beside the real database and the real neighbours. Reviewers click through the change instead of imagining it from the diff. On merge, the copy is gone.
What you get
Merge when it is reviewed
Not when staging is free. Every branch has its own stack, so nothing queues behind anything else.
Bugs found on the branch
Integration problems surface where they are cheap: on the pull request, not after the merge.
The evidence stays with the build
The suite's result, the reviewer's verdict and the product owner's note sit on the instance, next to the build they are about.
How it works
- 01
Compose the stack once
Your services as the Compose files you already have; the environment says which of them make up the application.
Your first environment → - 02
Four CLI commands in the pipeline
Create, deploy with --wait, read the URL, delete when the pull request closes. A service-account key with the deployer role and nothing more.
GitHub Actions and GitLab CI, line by line → - 03
Checks and a verdict on the instance
The pipeline writes what it found; a reviewer approves or rejects with a note. The history keeps every attempt.
