Want help adding license keys to your extension?
Keyturn Kit is the license-key code we use: the free edition is MIT on GitHub, and Pro adds Polar, Dodo Payments, Gumroad and Payhip, a free trial and free uses per day. If you’d rather have help fitting it into your extension, email us and we’ll reply.
Tell us what the extension does, how it’s built (WXT, Plasmo, plain Manifest V3), which seller you use or want, and which features should be paid. Please don’t send access to your repository in the first email.
To do it yourself, Selling a Chrome extension with license keys, no backend walks through it.
