Quickly deploy preview environments to the cloud!
The community resource for ephemeral environment best practices
Open source, self-hosted preview environment manager: a copy of your app for each git branch, on your own server, with its own URLs, database and logs, for teams and their coding agents.
On-demand ephemeral test environment provisioning — PR-based isolation, lifecycle state machine, TTL policies, resource tracking, cleanup scheduling. TypeScript/Node.js + PostgreSQL + Redis + Docker + GitHub Actions CI.
To associate your repository with the pr-environments topic, visit your repo's landing page and select "manage topics."
