the part nobody tells you about
License keys, machine activation, and a fail-closed offline grace window are fiddly to get right — and easy to ship insecure.
Selling worldwide drags in VAT, sales tax, and reporting. Get it wrong and it’s your problem, not your customer’s.
Developer ID signing, notarization, stapling, and a CDN stand between your build and a download users will actually open.
what you get
licensing
A Rust crate validates keys, node-locks the machine, and keeps working offline within a grace window. One build runs locked (free demo) and unlocks at runtime when a license validates — no separate demo binary, no recompile.
checkout
Sell through a Merchant-of-Record (you bring Paddle): VAT and sales tax handled worldwide. A webhook mints a license key on purchase and revokes it on refund. You never touch billing or tax.
distribution
One command (or a GitHub Action) builds → codesigns → notarizes → staples → publishes your .dmg to a CDN. The Apple gauntlet, scripted.
Scaffold a new monetized app in ~8 config values.
how it works
The licensing core is a runtime gate — add the plugin, check unlocked(),
ship. No second “pro” build to maintain.
// 1. add the crate, gate paid features at runtime
app.add_plugins(LicensingPlugin::keygen(config));
if licensed.unlocked() { /* paid feature */ }Drop in the licensing plugin and guard paid code paths behind a runtime check. One binary ships as a free demo and unlocks when a key validates.
Purchases become license keys automatically via webhook; refunds revoke them. You stay the Merchant-of-Record — tax handled, money never touches us.
Build → codesign → notarize → staple → publish. Out comes a signed, notarized download. Done.
why trust it
Rustify is extracted from LATTICE, a real macOS Rust app already selling through this exact stack. The gotchas — keygen’s license-auth scheme, fail-closed offline grace, Apple notarization — are already hit, debugged, and shipping. macOS today; Windows & Linux next.
who it’s for
The licensing core is framework-agnostic — thin adapters wire it into whatever you render with. If it’s a native Rust GUI, it fits.
questions
Any native Rust GUI. The licensing core is framework-agnostic; thin adapters cover Bevy, egui, winit, Slint and friends.
No. You bring your own Merchant-of-Record (Paddle); Rustify never touches your money. We’re tooling, not a payment processor.
macOS first (Apple Silicon proven, end to end). Windows and Linux are on the roadmap.
Yes — you stay the seller and own those relationships. Rustify wires them together; it doesn’t sit between you and your customers.
