Flutter
Dart plugin
One Dart codebase, both stores. Federated plugin wrapping the native Android + iOS SDKs underneath.
Open source — Apache 2.0
Send data over sound
Open-source SDKs for ultrasonic data exchange between nearby devices. No Bluetooth, no WiFi, no pairing.
How it works
Three simple steps. No hardware, no pairing, no setup.
01
Encode
Turn any data payload into an audio signal — audible or ultrasonic.
02
Sound
The encoded signal travels through the air via the device speaker. No network needed.
03
Decode
A nearby device picks up the audio with its microphone and extracts the original data.
Use cases
Any scenario where two devices need to exchange small data payloads nearby.
📡
Proximity sharing
Share links, contacts, or tickets with people nearby — just play a sound.
🔗
Device pairing
Pair devices instantly by playing a short audio handshake. Works with any speaker.
🔌
IoT provisioning
Configure smart devices by sending Wi-Fi credentials or setup data over sound. No app pairing flow.
🎤
Live events
Push interactive content to every phone in the venue simultaneously via the PA system.
Build with Beeping in your stack
One protocol, every runtime. Same simple API across native SDKs, web packages, server-side bindings and the HTTP layer.

HTTP API
beepbox-server (REST)
Any language, any runtime — call the beepbox REST API directly. OpenAPI 3.1 spec ships generated clients for the common stacks.
Node.js

Async Python client (httpx) for the cloud mode plus a pybind11 native binding for offline encoding. Type-checked with mypy strict.
Terminal
C++ Core

The C++20 library every other binding wraps. For embedded targets or custom integrations where you want zero glue.
CLI
beeping-cli (Rust)
Encode / decode / inspect from your terminal. Cross-compiled binaries via Homebrew, Scoop, cargo install or GitHub Releases.
