Open Source Data Security & Privacy Software
Data Security & Privacy software provides methods for encrypting messages, files, and network traffic to prevent unauthorized access. These tools implement end-to-end encryption and decentralized protocols to secure communication and storage. This type of software serves individuals and organizations that need to manage their own encryption keys and metadata. Self-hosting these apps ensures that private chat histories, documents, and network logs remain on hardware you manage. This approach removes reliance on external servers for storing sensitive identity information and private media.
This page lists 44 open source tools in the Data Security & Privacy category. The most popular are LocalSend, AdGuard Home and Tailscale. Most use the AGPL-3.0 or Apache-2.0 license, and 34 offer an official Docker image.
