I wrote an electron app and I just charge per license. It's an Apache Parquet format viewer https://www.parquetviewer.com

I've actually specified that a single license is per a single user but can be installed on multiple machines. I've had several users request this.

How are u managing piracy? With a same username or license - can the software be used by many people? Or you can lock some license remotely?
