Your phone, laptop, watch and sensors form a private mesh - no cloud, no logins, no middleman. When technology works for you instead of harvesting your data, it gets out of the way.
Early development - everything here is experimental
A mobile-first mesh protocol for phones, wearables and IoT. Your devices find each other, prove who they are, and communicate securely - without logins, without pairing screens, without a cloud in the middle. The same code runs on a $5 microcontroller, a phone, a laptop, a server, or inside your web browser.
No passwords, no pairing dialogs, no login screens. Devices in a trust group recognise each other through cryptographic certificates. If you're a member, you're in. Authentication is invisible.
One Rust codebase compiles to bare-metal microcontrollers (ESP32, RP2040), Linux SBCs (Raspberry Pi), desktop, mobile, and 70KB of WebAssembly in the browser. A $5 chip and a cloud VM are equal peers.
BLE, WiFi, LoRa, USB, WebSocket - R2 treats them all the same. Networks come and go. The system adapts, routes around failures, and strengthens paths that work.
The protocol runs on your devices. A relay helps with connectivity across the internet, but it's untrusted infrastructure - it forwards encrypted bytes it cannot read. Your data never touches someone else's server.
Capabilities, from private notes to industrial sensing to AI. Not apps - these are active, distributed, and belong to your trust group, not to someone else's platform.
Private encrypted notes that sync across your devices. No accounts, no cloud, no data harvesting.
The universal R2 runtime. Adapts to available transports: WebSocket, UDP, BLE, LoRa. Every hive is a wayfinder. Run anywhere from a $5 VPS to a Raspberry Pi.
AI reasoning engine built on R2. Autonomous agents (ANTS) that think, research, and collaborate within trust groups.
Encrypted messaging within and between trust groups. Private channels inside your group, scoped conversations across entangled groups. Real-time text across any R2 transport.
Environmental monitoring across landscapes. Water level, temperature, rainfall. Multi-transport mesh that works when infrastructure fails. Built on R2.
Wireless sensor mesh for workshop and lab environments. Vibration, temperature, pressure, strain - edge intelligence detects anomalies and alerts before something breaks.
R2 is specification-driven. Formal specs and test vectors are the source of truth - code is generated from them. AI helps build the implementation; the specs ensure correctness.
50+ formal specifications with conformance test vectors. The definitive source for every protocol layer - wire format, trust model, transport bindings, sentant lifecycle.
no_std protocol crates: r2-wire, r2-cbor, r2-fnv, r2-trust, r2-route, r2-transport, r2-engine. One codebase, every target.
r2-wasm wraps the protocol stack for browsers via wasm-bindgen. Trust groups, frame encode/decode, encryption - 70KB gzipped.
Full R2 stack on the BEAM VM. Sentant execution, trust group management, GraphQL API. Rust NIFs for the protocol core. Built for gateways and servers.
