Cosmos

Cosmos provides a self‑hosted gateway and management layer for server‑side applications. It sits in front of services such as Plex, HomeAssistant, blogs or custom containers, offering reverse‑proxy routing with automatic HTTPS, multi‑factor authentication, and a zero‑trust identity provider. The platform includes a built‑in VPN, encrypted incremental backups via Restic, and real‑time monitoring with alerts, allowing users to access their services securely from anywhere without opening router ports.

The system bundles an app store for installing and updating applications, a storage manager that handles local disks, parity disks, and MergerFS, and network‑storage integration powered by RClone for remote sources like Dropbox or NFS. Container management supports Docker‑Compose files, while the SmartShield technology adds additional security checks and protections.

Targeted at individuals, families, and small‑to‑medium businesses that wish to retain full control over their data, Cosmos is a self‑hostable, open‑source solution released under Apache‑2.0. It emphasizes privacy, cost control, and eco‑friendly local hosting while delivering enterprise‑grade security features without a subscription model.
