What is BitChat? The 2026 Ultimate Guide to Offline Messaging
Welcome to TechFir.com. In an era where internet shutdowns, data breaches, and corporate surveillance are becoming common, a new technological marvel has emerged: BitChat. This isn't just another messaging app; it is a movement toward digital sovereignty. This guide explores how BitChat allows you to communicate without the internet, who built it, and how it is poised to disrupt the social messaging landscape.
What is BitChat?
BitChat is a decentralized, peer-to-peer (P2P) messaging application designed to operate without the internet, cellular service, or central servers. Developed by Jack Dorsey (co-founder of Twitter and Block, Inc.) and released in July 2025, it uses Bluetooth Low Energy (BLE) mesh networking to send messages directly between nearby devices.
Who Made BitChat?
BitChat was developed by Jack Dorsey (the co-founder of Twitter and Block, Inc.). Announced in July 2025 as a "weekend project," Dorsey envisioned BitChat as a tool for resilient, censorship-resistant communication. It was built by Permissionless Tech, LLC and is entirely open-source, allowing developers worldwide to audit its code on GitHub.
Key Features of BitChat
- Infrastructure Independence: Works during internet blackouts or natural disasters.
- Multi-Hop Routing: Messages can "hop" up to 7 devices to reach someone far away.
- No Identity Requirements: No phone numbers, emails, or SIM cards needed.
- Emergency Wipe: A "Panic Mode" that erases all data with a triple-tap on the logo.
- Ephemeral Messaging: Messages disappear by default after 12 hours.
BitChat vs. Traditional Apps (WhatsApp/Telegram)
The primary difference lies in Ownership and Metadata. While WhatsApp is owned by Meta and requires a phone number, BitChat is owned by no one and requires nothing but a Bluetooth signal.
| Feature | WhatsApp / Telegram | BitChat |
|---|---|---|
| Network | Centralized (Internet Required) | Decentralized (Offline Bluetooth Mesh) |
| Identity | Phone Number / SIM | Cryptographic Public Key (Anonymous) |
| Data Privacy | Metadata Collected | Zero Metadata Collection |
| Resistance | Can be blocked by ISPs | Censorship-Resistant |
How to Download and Setup BitChat
Step-by-Step for Android:
- Navigate to the BitChat GitHub Releases.
- Download the APK file and install it on your device.
- Grant Bluetooth and Location permissions (required for BLE scanning).
- Set your nickname (e.g., /m @kamal) and start chatting in nearby #rooms.
Step-by-Step for iOS (iPhone):

Advanced Usage: IRC Commands
BitChat uses a classic IRC-style command interface for navigation:
- /j #channel: To join a topic-based public chat.
- /m @name: To send a private encrypted message.
- /pass [password]: To password-protect a channel you created.
- /who: To see who is currently in your mesh range.
