Show HN: Netscope – Inspect HAR Files on Your Desktop

2 points by Dru89 5 hours ago

Hey folks! I built Netscope because I couldn't find a desktop app for dealing with HAR files. I was annoyed at having to import them into Chrome DevTools every time (opening a new tab, opening DevTools, and importing it there). And using some kind of Web Tool like Google's HAR Analyzer was a no go for me. I didn't want to upload a HAR file that could have cookies, auth tokens, and other session data into some online tool.

Netscope gives you a Chrome DevTools kind of experience as a standalone desktop app. Open HAR files, filter the requests by type or domain, inspect headers, and also look directly at the raw HAR source. I built it to work with double clicking apps in the Finder, dragging and dropping them into the window, or opening through the menu. It also supports opening HARs in multiple windows so you can look at multiple at the same time.

I've been a web developer for a long time, and our teams often use HARs to help debug issues. It's been a great tool for me to pull up in an incident, so I can dig into a bug someone saw or share my screen and step through something together. I hope y'all will find it useful, too!

The app is available free and open source for macOS, Windows, and Linux. Built with Electron, React, and TypeScript. (I'm currently working through figuring out how to get the Windows app signed without paying six million dollars a year, so it still has the scary, red dialog for now.)
