Meshtastic is one. It requires nodes you connect your self to with Bluetooth. Your mobile is the UI then. Nodes use 868Mhz and connect to each other in ranges between 10-20km. Building an own node costs about 70-90€. Check out [https://meshmap.net/](https://meshmap.net/) to find one nearby.
Freifunk is another, which uses wifi only. It has entry/exit points to the internet on every node (but not required), using VPN tunnels to obscure the clients identity. Nodes can be linked to another in order to create a mesh network. I don’t know how popular this technology is outside Germany. [https://freifunk.net/](https://freifunk.net/)

Building a node can be done for under 20€ with a Heltec V3. Not the most power efficient, but not an issue if you're running it from usb power anyway. Also a note: the map doesn't show all nodes, my node can see a lot more devices around me than are listed on the map. Maybe some issues with reporting or something (which is optional in the first place)
