THE PRODUCT
What it solves.
Selling a digital file should not require a large commerce stack. Papertill packages the path from payment to delivery into a small, inspectable software kit. Its own storefront uses the same implementation.
THE ENGINEERING
How it works.
A dependency-free Worker handles Stripe Checkout and signature-verified webhooks. Licence keys are derived deterministically; HMAC-signed download links expire. Cloudflare KV stores the downloadable product. The repository includes a buy-to-download verification harness.
