Format & delivery
Delivered as a HTML · browser app. Open it in any modern browser — no install, no account, no server. It works offline, and the file is yours to keep.
Immediately after your Lightning payment settles, the download link appears at checkout. No account, no email, no waiting for a message.
How buying works
Pay from any Lightning-enabled Bitcoin wallet. The checkout creates an invoice for the fixed USD price and unlocks the file when the payment settles. An on-chain fallback is available. If you do not have Bitcoin yet, the no-card guide explains the shortest route.
