Questions
Is Keydrop really free?
Yes. Keydrop is MIT licensed and has no paid plan. You pay only for your own Cloudflare usage, and the free Workers plan is enough for small projects.
Do I need my own server?
No. Keydrop runs on Cloudflare Workers with a D1 database in your Cloudflare account. Deploying takes one click.
Do I need Stripe?
Only if you want to sell codes. Free claim campaigns, direct assignment and the API work without Stripe.
Can I hand out App Store offer codes?
Yes. Import App Store offer codes, promo codes or any other platform's codes from CSV or Excel, then distribute them like any other code.
Can I change the look and the copy?
Yes. All text lives in one file per language, and the README lists which files to edit for the brand, colors, homepage and icons.
Do I have to credit Keydrop?
No. The MIT license only asks you to keep the license file. The small “Powered by Keydrop” link is on by default, and you can turn it off.
