This is my 3rd (or is it 4th?) year of developing and selling Label LIVE, an electron app for designing and printing labels. Originally it only worked with USB thermal printers, but over the last few years it's grown into a multi-function image-rendering pipeline that integrates data import (via spreadsheet, CSV or API) with barcodes, text, image output. My app revenue eclipsed my iOS/NodeJS consulting in 2021 and I hope to double revenue in 2022. Read more at

The tech stack for this app is really interesting (to me at least, natch). Lots of native node modules that need finesse on both macOS and Windows. I don't yet support Linux because out of thousands of users, only 2 people have emailed about Linux support (probably both from HN!).
I really love building Electron apps. It's a total joy bringing something (albeit "inefficiently" wrt memory and "native" qualities) like this to market for a niche that's otherwise a dumpster fire of old and clunky 1980s-era Windows-only software.
As for licensing, Label LIVE is licensed per computer. I wrote a custom license implementation leveraging JWT. The JWT is signed by my license server and the app verifies the signature and that the contents match the "fingerprint" of the computer being licensed, expiration, etc.
