Cosmos Server is a self-hosted home server platform that acts as a secure gateway and server manager for personal applications.
The tool addresses the vulnerability of self-hosted applications by providing a unified security layer in front of them. It works as a reverse proxy that sits between users and their services, applying authentication, anti-DDoS protection, and anti-bot measures to all connected applications without requiring individual service configuration. This approach lets users run services like Plex, Home Assistant, or personal blogs while delegating security concerns to a single hardened entry point.
Cosmos suits anyone running self-hosted services on a server, NAS, or Raspberry Pi who wants to avoid the complexity of securing each application individually. It is designed to be straightforward to install and use while providing enterprise-grade protections out of the box. The tool is particularly valuable for users who lack the expertise to configure reverse proxies, SSL certificates, and authentication systems manually across multiple services.
The project shows active development with regular commits addressing bugs and feature requests. The maintainer responds to issues and pull requests, indicating ongoing engagement with the user base. Documentation is maintained alongside code changes, suggesting a commitment to keeping guidance current with the tool's evolution.
