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.
Best for $50+ contributions where the Lightning channel-balance limit might be a concern.
Roughly in this order: paying contractors to ship the v0.2 web UI auth hardening, recurring billing primitives, additional language SDKs (Go, Swift, Java, .NET), and the long tail of papercut fixes that operators report. A small slice covers infrastructure — the marketing site, the docs site, the marketplace registry. We publish quarterly transparency reports of what came in and where it went, signed by the keysat.xyz issuer key.
If you’d rather fund Bitcoin software development broadly rather than this project specifically, OpenSats is a 501(c)(3) public charity that grants to dozens of FOSS Bitcoin projects (BTCPay, Fedimint, Cashu, NoStr clients, …). They take Lightning. Keysat itself relies on BTCPay, which OpenSats supports.
