A receiver in a browser tab
BrowserSDR brings a local software-defined radio interface to the web, using WebUSB to connect to receiver hardware. The project combines tuning and signal displays with recording and replay.
Spectrum and waterfall
The live spectrum gives a view of signal activity across frequencies. The waterfall adds a history over time, making changes in the signal easier to see.
Recording and replay
Capture a session and come back to it later. Recording and replay sit alongside the live receiver so that a signal can be explored again after the original listening session.

Open browsersdr.com to explore the receiver and its current setup guidance. Hardware support and browser requirements should be checked in the app before connecting a device.
