April 16, 2024 -
Hey everyone,
I recently needed an app to browse a very large JSON file (>500MB) and could not find any open source app for Linux that could really do that. So I decided to make one myself and am now happy to share it with everybody, who might be interested.
The app is called Janice. It is written in Go and made with the awesome GUI toolkit called Fyne. It runs on Linux (AppImage), Windows 10/11 and macOS (experimental).
