Biper in three sentences
Biper is a small radio cube and a free, open system that let two non-technical people message each other with no internet, no coverage and no subscription. The cube transmits on the open MeshCore network — thousands of nodes in Poland already — and talks to every device on it. The project is run by one person and publishes its evidence as it goes, including what has not been measured yet.
Facts
Numbers you can check
Every entry is backed by evidence on the project page; what we have not measured, we say so.
- What it is
- the Biper system (a MeshCore fork, MIT licence) + the M5Stack Unit C6L cube (109 zł in Poland, August 2026)
- Status
- system v0.9.0 publicly in the web installer; first message through the page on 17 August 2026; the cube pair talks both ways on our build from two phones (20 August 2026)
- The network
- MeshCore: more than 4,400 reported nodes in Poland, over 2,200 on air within the last month (measured from the official map, 19 Aug 2026)
- The user path
- installation from a browser, a panel served from the cube’s own flash over its own Wi-Fi — no account, no app, no internet
- The rules
- the six commitments of the Biper Charter, including rescue-stays-free and openness about AI
- Who is behind it
- a community project by Tomasz Fiedoruk (MAGNET MEDIC, Czaplinek, Poland); development is AI-assisted and says so plainly
