CapRover
A self-hosted PaaS that wraps Docker Swarm behind a friendly CLI and dashboard so teams can push-to-deploy apps and one-click databases on their own VPS. Standout trait is how much Heroku-like ergonomics it squeezes out of plain Docker Swarm.

⚙ Full Stack
Node.js/Express control-plane driving Docker Swarm mode, with NGINX as the edge proxy and Let's Encrypt automation baked in. App/database state lives in Swarm volumes and a captain-definition JSON file, not a managed DB.
📈 Scaling Analysis
Scales reasonably for small-to-mid self-hosted fleets via Swarm's built-in service replication and rolling updates, but the single-manager-node default is a scalability and availability ceiling until you manually add manager quorum. Not designed for the elastic, stateless horizontal scaling of a Kubernetes-native platform.
🚀 Running on Nexlayer
Runs as a single privileged pod that itself talks to a Docker socket, which sits awkwardly inside Nexlayer's per-app pod model since CapRover expects to own the whole node's container runtime; better suited as a nested demo than a first-class Nexlayer citizen. If deployed, give it its own pod with a persistent volume for `/captain/data` and route captain UI traffic through `<podName>.pod:3000`.
