ContactHub is a secure, federated contact information sharing service designed to protect your privacy. By using the ActivityPub protocol, ContactHub allows you to host your own server and share your contact information with others in a decentralized manner. Websites like Amazon, online shops, or any other site requiring address information can use our OAuth integration to securely access user contact information, automatically updating it when a user modifies their details.
Detailed documentation is available to help you understand the ContactHub architecture, protocol, and implementation. Here are the main sections of the documentation:
ContactHub can be implemented in various programming languages, allowing you to choose the most suitable language for your server. Check out the available implementations and follow the instructions in their respective README files:
Try out ContactHub with our example instance hosted at contacthub.family. This instance allows you to experience the features and functionality of ContactHub without having to set up your own server.
We welcome contributions to the ContactHub project! If you have any suggestions, bug reports, or feature requests, please open an issue on the GitHub repository. If you'd like to contribute code or documentation, feel free to submit a pull request.
