Quick Verdict
Cosmos Cloud is a full self‑hosting platform that provides container management, a built‑in reverse proxy, an app marketplace, VPN integration, identity provider, and security features. Lazydocker is a terminal UI dashboard for quick Docker monitoring and interaction. Use Cosmos Cloud for comprehensive platform management and Lazydriver as a complementary SSH‑based debugging tool.
Overview
- Cosmos Cloud – a self‑hosted operating system for managing Docker containers, reverse proxy, app marketplace, VPN (Constellation), multi‑user authentication (2FA), and security (Smart Shield). Current version: v0.20.2.
- Lazydocker – a terminal UI (TUI) that shows real‑time dashboards of containers, images, volumes, and logs. It is a single binary with no server component; run it via SSH when needed. Current version: v0.24.4.
Feature Comparison
| Feature | Cosmos Cloud v0.20 | Lazydocker v0.24 |
|---|---|---|
| Interface | Web UI | Terminal UI |
| Container lifecycle | Full management | Start/stop/restart/remove |
| Built‑in reverse proxy | Yes (with SSL) | No |
| App marketplace | Yes (curated store) | No |
| Docker Compose support | Yes | No |
| User management | Yes (multi‑user, 2FA) | No |
| VPN integration | Yes (Constellation) | No |
| DDoS protection | Yes (Smart Shield) | No |
| Identity provider | Built‑in OpenID | No |
| Log viewing | Yes | Yes (real‑time, colored) |
| Resource monitoring | Yes | Yes (CPU, RAM per container) |
| Shell into containers | Yes | Yes (exec) |
| Auto‑updates | Yes | No |
| Always running | Yes (background) | No (on‑demand) |
| RAM usage | ~150‑200 MB | ~10 MB (while active) |
When to Choose Which
Choose Cosmos Cloud when you need:
- A single platform to manage containers, reverse proxy, and security.
- An app store for one‑click deployments.
- Multi‑user access with authentication (2FA).
- Built‑in reverse proxy (replacing separate NPM/Traefik).
- VPN connectivity between devices.
- A polished web UI accessible from any browser.
Choose Lazydocker when you need:
- Quick, zero‑overhead Docker monitoring via SSH.
- Real‑time log tailing across multiple containers.
- A lightweight tool that doesn’t run as a persistent service.
- Terminal‑based workflows.
- A complementary tool alongside an existing management platform (e.g., Cosmos Cloud, Portainer, Dockge).
Both tools are complementary: you can run Cosmos Cloud as your primary platform and use Lazydocker for fast, SSH‑based troubleshooting. Lazydocker can see and manage all Docker containers regardless of how they were deployed, including those managed by Cosmos Cloud.
Compatibility & Resource Usage
- Resource efficiency: Cosmos Cloud uses ~150‑200 MB for its combined functions. Portainer (~100‑200 MB) plus NPM (~80‑120 MB) totals ~200‑320 MB, making Cosmos Cloud slightly more efficient as an all‑in‑one solution.
- Architecture support: Lazydocker provides ARM64 binaries and works on Raspberry Pi 4/5, ARM‑based VPS, and Apple Silicon (via Docker for Mac).
