DeltaChat Developers

DeltaChat Developers is an open-source collective that re-imagines instant messaging by turning any existing e-mail server into a federated chat network. Their sole, mature product, DeltaChat, presents itself as a familiar messenger interface while quietly using the decades-old SMTP/IMAP infrastructure for message transport; this approach removes the need for centralized accounts or proprietary silos and gives users end-to-end encryption via Autocrypt and OpenPGP whenever possible. Typical use cases range from privacy-minded individuals who want WhatsApp-style convenience without vendor lock-in, to NGOs operating in regions with restrictive networks that block traditional chat platforms, to small businesses that prefer to keep conversations on their own mail domains. The client is lightweight, supports groups, voice messages, file sharing, and even webxdc applets for collaborative editing, yet it interoperates with regular e-mail contacts who may never install the app. Because the protocol is plain e-mail, chats can be searched, filtered, and archived with any mail tool, and switching devices is as simple as adding an IMAP account. DeltaChat’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always providing the newest release and allowing several applications to be installed in one batch operation.
