Internet Walkie-Talkies You Control.
TapSignal is a push-to-talk radio app that runs on your own server. Instant voice communication with friends, family, or your team — no accounts, no cloud, no tracking. Just press and talk.
Features
Everything you need for instant voice communication.
Push to Talk
Hold the button. Talk. Release. Your voice reaches everyone in the channel instantly — just like a real radio.
Works Everywhere
Native apps for iOS and Android plus a web client that works in any browser. No installs required.
Lock Screen Ready
iOS Live Activity puts PTT right on your lock screen. Transmit without unlocking your phone.
Private & Secure
Invitation-only channels. No sign-ups, no phone numbers. Your conversations stay between you and your server.
Self-Hosted
Run TapSignal on your own hardware. Your data, your rules. A $5 VPS handles 50 users easily.
Open Source
Fully open-source under a permissive license. Inspect the code, contribute, or fork it for your own needs.
Self-Hosted: Your Radio, Your Rules.
Getting started takes a few minutes, not a few days.
The TapSignal server is lightweight, easy to run, and configurable via environment variables. Run it in Docker, on a cheap VPS, even a Raspberry Pi.
TapSignal is a single binary with zero external dependencies. Run it with Docker or build it from source.
docker compose up -d
That's it. Open the admin dashboard, create a channel, and share the invite link with your people. See the GitHub repo for full setup instructions.
