As an electron developer I used NodeJS to implement a custom licensing system on top of JWT. My app "registers" a computer (fingerprint) with the server. The server can grant licenses where it signs a JWT with a secret key, and the client can verify using the public key. The client will enable features based on the JWT payload. Again... it's crackable, but it's serviceable and I make my software affordable through either a one-time license ($147) or a monthly subscription ($14.99/month). I try my best to make it "worth it" to purchase the app. Label LIVE is a super- boring business label printer app so it takes a "special" person to 1) need the app and then 2) decide that they'd save more money by cracking it than just paying for it. If I 10x my pricing (as my competition does), then I would fully expect users would find it worthwhile to crack and distribute.
