SublimeKeys

SublimeKeys handles the boring-but-critical parts of selling software: license key issuance and verification, Stripe-powered subscriptions and one-time purchases, and a customer dashboard — so indie developers can focus on the product instead of building a licensing backend from scratch. Official Python and Node.js SDKs support offline verification, and the whole platform ships in 12 languages. Built by a solo founder, for solo founders shipping paid desktop and web apps.
