A chat app with no internet and no servers gained 1,700 stars in a day

A chat app that needs no internet, no servers, and no phone number just gained 1,700 GitHub stars in a day.

bitchat — open-source, "Bluetooth mesh," with self-described "IRC vibes" — is trending hard (+1,720 stars today). It relays messages phone-to-phone over Bluetooth, so a group can talk with no cell signal and no central server in the middle.

Why it matters: Offline mesh chat keeps resurfacing for the same reasons — protests, disasters, festivals, dead zones, and privacy. No servers means little to censor and little to seize.

Know this: range is short (it's Bluetooth), so it shines in a crowd where phones relay for each other. It's not a WhatsApp replacement — it's a "when the network is down, or watched" tool.

Sometimes the most futuristic idea is a network no one owns.
