Stolo is an encrypted messenger that built off of Reticulum and LXMF Out of the box it is a private, end-to-end encrypted messenger: no account, no phone number, no sign-up. Your identity and your history live only on your device, and Stolo's gateway relays your messages across the internet. When you need more, the same app becomes your own network. Create a network, share one invitation, and everyone who joins is in each other's contacts, trusted, automatically. Phones link directly over Wi-Fi and cellular, and optional long-range LoRa radios carry messages where there is no signal at all. Messages to someone out of range wait and are delivered when they come back. What you can send, on or off the grid: • Messages, photos, and voice notes, end-to-end encrypted. Only the people in the conversation can read them. Not us. • Live GPS positions on a built-in offline world map. See yourself and your team with zero connectivity. Under the hood, Stolo is built on Reticulum, the open cryptographic mesh stack, and sets up in a minute with no config files. Used for backcountry trips, maritime, job sites, disaster response, and everyday group chats that should stay between the people in them. Built on privacy. Works every day, everywhere, and keeps working when nothing else does.
