Open-Source at NSL.SH

At NSL.SH, we believe in the power of open-source. Our projects are designed to provide accessible, transparent, and flexible solutions for self-hosting and containerized environments. Below, you’ll find an overview of the key open-source projects we maintain, their purpose, and where to find them.

Docker Images

All our official container images are available on Docker Hub:

NSL.SH Docker Images

These images power our open-source infrastructure, including:

  • CasaIMG: A Docker-based distribution of CasaOS.
  • Mesh Router: A lightweight networking solution for dynamic domain management.

​

CasaIMG

Self-Hosting with CasaOS

📌 Source Code

CasaIMG packages CasaOS into a streamlined Docker container, making self-hosting applications easier. It extends CasaOS with features like:

  • Simplified deployment via Docker
  • Environment-variable-based configuration
  • Automatic domain and port management for hosted apps
  • Seamless integration with Mesh Router for external access

​

Mesh Router

Dynamic Domain Management for Containers  
📌 Source Code
Mesh Router simplifies domain routing for self-hosted applications, allowing users to map containerized services to custom subdomains dynamically. Key capabilities include:

  • Domain provider & requester roles – register subdomains or act as a provider
  • Encrypted communication via WireGuard VPN tunnels
  • Flexible domain formatting to avoid certificate limitations
  • Cloudflare integration for SSL and security enhancements

This tool is particularly useful for NAS setups, home labs, and decentralized hosting where direct public IPs are not always available.

🚀 Why Open Source?

We believe in transparency, community-driven development, and giving users control over their infrastructure. Open-source ensures:

  • Security through visibility
  • Collaboration and contributions from the community
  • Independence from proprietary solutions

By sharing these projects, we aim to empower users with robust, self-hosted alternatives to commercial services.
