Keysat is source-available and free to run. There’s no SaaS dial-home, no auto-deducted percentage of your sales. If the project is useful to you, here are three ways to fund continued development.
Same Keysat binary as the standard license, just priced higher. The admin UI shows a "Patron" badge in your dashboard. The cleanest way to support development — same purchase flow you’re already familiar with from buying any other Keysat license.
Tip any amount over Lightning. Hosted on Primal — works in any Lightning wallet that supports LN addresses.
If you’d rather fund Bitcoin software development broadly rather than this project specifically, OpenSats is a 501(c)(3) that grants to dozens of FOSS Bitcoin projects — including BTCPay, which Keysat depends on.
