The story

Beeping isn't new — it's back. Founded in 2015, paused in 2018, and reborn in 2026 — same idea, better hardware, open-source from day one.

🌟

2015
Founded
Beeping starts — making data travel through sound.

🛑

2018
On hold
The original team scatters. The idea stays parked.

2026
Reborn
Open-source, multi-stack, back for the new era.

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.

Explore

Two lenses on what Beeping enables — pick the one you care about.

🔀Dual mode🎯Use cases

Your choice. Same API.

Every SDK supports both modes. Switch at runtime with one line.

☁️

Cloud mode

API key

  • Zero setup — just add your API key
  • Encode & decode via HTTP API
  • Usage dashboard in developer portal
  • Auto-scaling, zero infrastructure

🔌

Local mode

On-device

  • beeping-core embedded natively
  • Works offline — no network needed
  • Full privacy — data never leaves device
  • Lowest latency possible

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.
