Uncloud

Uncloud is a lightweight tool for deploying and managing containerised applications across a network of Docker hosts. It forms a secure peer-to-peer cluster without a central control plane, aiming to provide a simple, PaaS-like workflow for running Docker Compose apps on your own infrastructure.

Key Features

• Deploy and scale services across multiple machines using Docker-like CLI commands
• Docker Compose support for defining multi-service applications and volumes
• Decentralised architecture with peer-to-peer state synchronisation (no central control plane/quorum)
• Automatic WireGuard mesh networking with peer discovery and NAT traversal
• Built-in service discovery via an internal DNS server
• Built-in ingress and load balancing across replicas on different machines
• Automatic HTTPS with certificate provisioning and renewal via Caddy and Let’s Encrypt
• Persistent storage support using Docker volumes managed across machines

Use Cases

• Run a small-to-mid-size production app stack on VPSs and bare metal without Kubernetes
• Build a multi-provider, highly available deployment by spreading replicas across regions
• Homelab or SMB platform for repeatable Docker Compose deployments with HTTPS and discovery

Limitations and Considerations

• Project maturity may vary by release; some features mentioned as planned (for example, automatic rollback) may not be fully available

Uncloud fits teams and individuals who want a pragmatic middle ground between single-host Docker and full Kubernetes. It emphasizes low operational overhead while still providing the core primitives needed for reliable multi-host deployments.
