From an empty project to a paid customer

One path connects implementation, licensing, checkout, and delivery.

    Create the productAdd your Unity asset, plugin, tool, or game.
  2. 2
    Install the SDKImport the PermitCore Unity package and paste the validation call.

Built for Unity workflows

Use async validation from runtime code or editor tooling. Pass product IDs to prevent a key issued for one product from unlocking another.

Online and offline licensing

Start with live validation. Professional and Enterprise plans add signed offline tokens for unreliable or air-gapped environments.

Licensing and checkout together

PermitCore can create the license, validate it inside Unity, sell it through your Store, and deliver it after payment.

Create → implement → sell

The license is only half the product.

Traditional licensing tools stop at webhooks. PermitCore gives your customer a real product page, checkout, receipt, and working key with one Stripe, Paddle or Lemon Squeezy account selected for your Store.
