Description

GRAJ License Manager gives digital product sellers a simple WordPress dashboard for creating product records, issuing activation codes and validating customer licenses.

The free edition is intentionally focused: it handles products, manual licenses, domain limits, admin validation, a public license verification endpoint and basic delivery through WordPress email.

Free features

  • Create unlimited product records with setup URLs.
  • Store product type metadata for non-WordPress products.
  • Create editable setup pages per product.
  • Render setup instructions with [graj_product_setup product_id="my-product"].
  • Set domain limits per product.
  • Create manual activation codes.
  • Validate licenses from wp-admin.
  • Public REST endpoint for license verification.
  • Optional domain registration during validation.
  • Basic license email delivery with wp_mail().
  • Event logs that store buyer email hashes.
  • Activation codes stored as hashes, not plain text.
  • Built-in admin documentation with the Free workflow and a clear Pro upgrade path.

Premium features

GRAJ License Manager Pro adds product versions, protected downloads, deploy provider connections, audit workflows, payment webhooks, n8n fulfillment, advanced email providers and secure product update automation.

Security model

  • Activation codes are never stored in plain text.
  • Lookup keys use HMAC.
  • Admin forms use nonces.
  • Admin screens require manage_options.
  • Public verification responses avoid exposing buyer details.
  • Domain validation rejects local/private hosts.
  • Public verification has basic rate limiting.
  1. Upload the graj-license-manager folder to /wp-content/plugins/.
  2. Activate GRAJ License Manager from the WordPress Plugins screen.

  3. For stronger portability, add a master key to wp-config.php:

    define( ‘GRAJ_LICENSE_MANAGER_MASTER_KEY’, ‘replace-with-a-long-random-secret’ );

  4. Go to GRAJ Licenses -> Products and create your first product.

  5. Under Products configured, create its public activation form page so emailed licenses include the setup link.
  6. Go to GRAJ Licenses -> Licenses and create a manual license.
  7. Copy the activation code when it appears. It is shown only once.
  1. Dashboard summary with product, license and REST endpoint overview.

Is this a checkout plugin?

No. The free edition manages products and licenses after a purchase happens elsewhere.

Are activation codes stored in plain text?

No. Activation codes are hashed. The code is displayed only once when created.

Can I validate a license for a domain?

Yes. Send a site_url during validation or enter it in the admin validation form.

Does it send emails?

Yes, using WordPress native wp_mail(). For more delivery providers, use the Pro edition or an SMTP plugin.

What does Pro add?

Pro adds payment webhooks, n8n fulfillment, advanced email providers and update automation.

Does the setup shortcode work in Elementor?

Yes. The setup shortcode works in Classic Editor, Block Editor, Elementor and builders that render WordPress shortcodes.

Are Vercel-like platforms deployed automatically?

No. Frontend apps and Vercel-like platforms are handled as downloadable bundles in this phase. Automatic API deploys are planned as a separate future phase.
