Each pull request automatically gets its own isolated Kubernetes namespace and a dedicated Neon Postgres branch via an Argo CD ApplicationSet and a GitHub Actions workflow. The workflow builds a container image, creates a Neon branch with a compute endpoint, updates Argo CD application parameters, and posts a preview URL comment on the PR. The post also covers Neon's copy-on-write branching model, the GitOps separation of source and config repos, and required secrets configuration. ## Full article daily.dev links to this article rather than hosting it.
