The models' case: Native support for parsing Docker Compose, Helm charts, and Terraform templates into isolated preview environments per pull request, featuring robust database state. The models' main caveat: High initial setup complexity and configuration management overhead for simple single-service applications. The strongest alternative is Qovery — Purpose-built ephemeral environments that run on your own cloud account (AWS/GCP/Azure/Scaleway), so per-PR previews use real managed services and. Not unanimous: ChatGPT picks Northflank; Claude picks Qovery; Grok picks Railway.
