I've set off time to blog about getting my broadband RF scanner (connecting to USRP B200 via WebUSB) to work in WASM.
It's basically https://blog.habets.se/2026/08/Broadband-RF-scanner-revisite..., but in the browser.
I also have an AX.25 decoder (https://thomashabets.github.io/ruwasm/) and plain old FM receiver (https://cement.retrofitta.se/tmp/rtlsdr-fm/) already. The latter two work with RTL-SDR, also via WebUSB, so no software installs or setup required.
I've been meaning to make a "GNU Radio in the Browser" (well, gnuradio-companion-like) for my RustRadio project to build flowgraphs without coding, but not gotten to it yet.
With wasm, I see a future where the browser and thus web technologies are a UI toolkit for a Linux desktop environment. It already is, people hardly use GTK and qt anymore except for desktop environments or embedded like on cars due to performance limitations. It would be cursed to see a browser running within a browser. But then replacing a desktop environment might be the limit of replacing GTK qt and other UI toolkits with web technologies, making it unnecessary and opposite to the reason people use Linux which is performance
