Cert Warden
A self-hosted Networking & VPN app you can run on your own server.
Cert Warden is a self-hosted networking application that you run on your own server instead of renting it as a cloud service. Running it yourself keeps the data on your own network and lets you back it up however you like.
The project is developed in the open via GitHub, where it has earned 610 stars from the community. Repository activity was last recorded on Sep 9, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Networking changes can lock you out of your own server, so keep a fallback access path while you configure. Read the project's reverse-proxy and certificate notes carefully, open only the ports required, and test from outside your home network before relying on it.
Like every project listed on SelfHosted, Cert Warden is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
