SendOwl

YES

Replaceable in one session with an AI coding agent.

Selling and delivering digital files: a buy button, a payment, and a secure download link that expires, with licence keys and drip delivery on top.

Promptfree, for everyone, and the only version there is

Build me digital product delivery.

STACK
- One serverless function, S3-compatible storage, Stripe Checkout, SQLite for orders

BUYING
- The browser sends a product id only; the function looks up the Stripe price
- The order is created by the checkout.session.completed webhook, idempotent by event id

DELIVERY, WHICH IS THE WHOLE JOB
- On order, mint a download token: random, stored, tied to that order
- The download route validates the token, then issues a presigned URL valid for five minutes
- Cap downloads per token and record every one with a hashed IP
- Never expose the object key or a permanent URL

LICENCE KEYS
- Generate a key per order, store a hash of it, and expose a validate endpoint that rate-limits by key

WHEN SOMEONE SHARES A LINK
- Downloads past the cap fail with a page explaining how to get a fresh link by email

Include the schema, the token flow and the presigned URL helper.

What you lose

Expiring, single-use download links with abuse controls, which is the part people underestimate
Licence key generation and validation already built
Payment, VAT and delivery in one purchase, with nothing to host

If you would rather not build

Stripe Checkout plus presigned S3 URLs
Lemon Squeezy, if you want VAT handled too
Gumroad, for the simplest possible version

Why this verdict

our own opinion · changed only by a person

82/100

Verdict yes at 82. Stripe handles payment; the interesting work is a download token that survives being posted on a forum.
