*Alternative to WhatsApp* — Snikket is an open-source easy-to-use decentralized messaging app. It supports encrypted chats, voice and video calls and group messaging. It does not require a phone number, and allows you to add multiple devices on the same account. Once you create your private Snikket instance (either hosted or self-hosted), you can invite your family and friends to join you by sharing a simple link. Snikket is part of an open network based on the
standard messaging protocol XMPP, so you can also communicate with people on other Snikket instances and compatible messaging services.
