Open Source Security & Privacy Software
Security & Privacy software manages network access, identity verification, and data encryption to protect digital environments. These tools block trackers at the DNS level, establish private tunnels between remote servers, and handle single sign-on authentication for multiple applications. This type of software serves system administrators and developers who need to manage login credentials and network traffic on their own hardware. Self-hosting these apps ensures that authentication logs and private encryption keys remain on local infrastructure rather than on external servers.
This page lists 102 open source tools in the Security & Privacy category. The most popular are LocalSend, PocketBase and Pi-hole. Most use the AGPL-3.0 or Apache-2.0 license, and 87 offer an official Docker image.
