Keysat licenses are Ed25519-signed and Crockford base32-encoded. Verification is pure-function — no network, no daemon, no shared state. Hand the docs to your coding agent and tell it to wire licensing into your software; the integration is small enough to fit in one prompt.

Keysat’s gating happens at the operator’s self-license, not at the buyer’s. Every Keysat instance ships at Creator (free); pay only when you outgrow it.
+Solo creator selling one-time or perpetual licenses for a focused catalog.
+For creators monetizing seriously — multiple products, subscriptions, both Bitcoin and card buyers.
+Honest supporter tier. Same features as Pro; you’re funding Keysat’s development.
++ No fake feature gates: Patron is feature-identical to Pro. Pricing is a flat annual fee — we don’t take a percentage of your sales. +
+Yes. Define a discount code with type free_license and the buyer redeems it at checkout without paying. Useful for press, beta testers, partners, and giveaways.
v0.1 issues fixed-duration licenses (e.g. 1 year) with offline expiry. True recurring billing — auto-renew without buyer interaction — lands in v0.3 alongside license-tier upgrades, volume packs, and Zaprite card payments.
+Creator is free forever, capped at 5 products / 5 policies per product / 10 active discount codes — plenty for a solo creator selling one-time or perpetual licenses. Pro lifts every cap and unlocks recurring subscriptions plus the Zaprite payment gateway (cards, Apple Pay, bank transfers, in addition to Bitcoin). Patron is Pro with a public supporter badge; same features, you’re funding development. See the tier comparison above for the full breakdown.
+BTCPay (Bitcoin / Lightning) is the default and available on every tier. On Pro or Patron you can additionally connect Zaprite, which adds card / Apple Pay / bank transfer / more — with payments still landing in your wallet. Pick whichever your buyers prefer; you can switch the active provider at any time.
