Software License Key Api
SublimeKeys
Sell your desktop app. We handle the license keys.
SublimeKeys is a license key API for indie desktop app developers — generate, activate, and verify keys with one tiny endpoint. Device-locked activations, trials, and instant revocations, backed by offline verification that works up to 7 days without a network call. Built by a solo dev who needed this for his own apps (ReelNox Studio, BackDrop_, TimePeek), now open to everyone. Free tier included, live in 12 languages.

Built this because I needed real license key infrastructure for my own apps and didn't want to roll my own. Free tier included, live in 12 languages from day one 🙌
