I built an HTML5 RTL-SDR application
There are lots of RTL-SDR applications, but you have to install them. I used the HTML5 USB API that exists in Chrome (did you know about it?) to build one that you can run straight from your browser, on your computer or your Android phone.
I built an HTML5 RTL-SDR application launched on December 7, 2024 with 104 votes, #390 of 5,365 launches that month and more than 90% of that year's launches.
In plain words
This is a browser-based RTL-SDR application that runs directly in Chrome without installation, on both computers and Android phones. It leverages the HTML5 USB API to let users operate software-defined radio functionality from their web browser. The application eliminates the need to install traditional RTL-SDR software, making it accessible for developers and radio enthusiasts who want a streamlined, portable alternative to desktop applications.

ADB WrenchJan 2026 · adbwrench.com · ▲93Hey HN, We built ADBWrench – a browser-based ADB tool that connects to Android devices via WebUSB. No SDK install, no drivers, no PATH config. Just plug in and debug. The problem: Every Android dev knows the friction of setting up adb. Install platform-tools, fight with USB drivers (especially on Windows), hope `adb devices` shows something. Then remember the exact syntax for that one command you need. ADBWrench runs entirely in the browser. Open the URL, grant USB permission, done. The interesting part: There's an AI assistant built in. Describe what you want to do in plain English – "show…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
