Introducing packages.sweber.dev
Integral overview

IntegralLive demo.

Integral signs licenses with Ed25519 and checks them offline in your app. This page runs the same code as the npm package: it creates a key pair, issues licenses, verifies them and applies your plans.

Everything runs in this page. Keys and licenses never leave your browser.

Keys

One key pair per productThe private key signs, the public key only checks.

In a real project the private key stays on your server or in CI secrets. The public key ships with your app: it cannot create licenses, so it does not need to be secret.

Issue

Issue a licenseWhat a payment webhook or the CLI does.

Pick a plan and optional extras. The license is a signed string you can email, store in a file or paste into a text field.

Verify

Check it offlineChange anything and the signature breaks.

Edit the license, tamper with the plan or sign it with a stranger's key. Move the date to see expiry and update periods at work.

Entitlements

What the app unlocksPlans, features and limits from one definition.

Without a valid license the app falls back to the free plan. With one, it applies the plan plus the extras signed into the license.

})

Pro

Integral Pro: licenses from Polar, automaticallySimulated subscription, real signatures.

The license server of Integral Pro listens to Polar webhooks and keeps one license per subscription. Play through a subscription below. Each step re-signs the license the way the server does: renewals extend the update period, a cancellation keeps the installed version working, a refund revokes the license.
