GNUnet Messenger API

API for decentralized instant messaging using CADET

Communication is one of the most valuable goods, but it requires confidentiality, integrity and availability to trust it. The GNUnet Messenger API implements an encrypted translation layer based on Confidential Ad-hoc Decentralized End-to-End Transport (CADET). Through CADET the API will allow any kind of application to set up a fully decentralized form of secure and private communication between groups of users. The service uses e2e-encryption and does not require any personal information from you to be used.

You are able to send text messages, share files, invite contacts to a group or delete prior messages with a custom delay. Messages and files will both be stored decentralized being only available for others in the group. GNUnet provides the possibility to use this service without relying on the typical internet structures, with a turnkey optional DHT for sharing resources.

Unlike many other messengers out there the GNUnet Messenger service focuses on privacy. You decide who can contact you and who does not. You decide which information gets shared with others and which stays a secret. The whole service and its API is free and open by design to be used by many different applications without trusting any third party.

Run by GNUnet e.V.
