Teach your devices to sing… for free

Since we released our first SDK in 2015, we’ve loved seeing what people build with Chirp, from virtual reality group-building to underwater communications systems.

That’s why we’re proud to today announce that Chirp is entirely free for non-profit, hobbyist and commercial projects alike, to let people play, discover, learn and build

Just get our SDKs and start building

This new approach makes it easier for you to test out Chirp in a production environment.

Chirp’s new free tier is available at our admin centre and contains the following:

• Free unlimited usage to non-profit, hobbyist and free/open-source projects
• Free commercial use (up to 10k monthly active users)
• All of our off-the-shelf audio protocols — both audible and inaudible ultrasonic.
• Android, iOS, Python, JavaScript, Windows & macOS platforms
• Completely offline operation

However, we do offer more features on our enterprise licence which has more features such as bespoke protocols, more platforms, SLAs and an unlimited commercial use.
