Pricing
Freemium: the core DDLS WooCommerce plugin is free with unlimited products, licenses, and customers. Optional paid extensions are priced per year (€49-€149/yr each) or as bundles up to €449/yr for all 8 extensions. A separate desktop app, Claudius Corp, is sold as a one-time purchase (€99-€995).
DMSI (Dream Makers - Software Innovations), based in Greece, develops DDLS (Downloads, Licensing & Subscriptions), a WordPress/WooCommerce plugin that turns a WooCommerce store into a digital product platform: it automatically generates license keys on purchase, delivers protected/expiring download links, and manages recurring subscription billing and dunning without extra plugins. The core DDLS plugin is free and includes a REST API (60+ documented endpoints) and a customer self-service portal for managing licenses, downloads, and subscriptions. On top of DDLS, DMSI sells eight optional paid extensions - Update Server, Subscriptions Pro, Analytics Pro, Support Desk, Webhooks, Advanced API, Team Management, and Service Management - individually or in discounted bundles. Separately, DMSI also sells Claudius Corp, a desktop application described as an AI-agent-powered 'virtual company framework,' sold as a one-time license.
Key Features
Automatic License Generation — DDLS automatically generates a license key when a customer completes a WooCommerce order, with configurable activation limits and expiration.
Secure Digital Downloads — Protected file delivery via expiring download links, with version history tracking for updated files.
Built-In Subscription Billing — Handles recurring payments, automatic renewals, and dunning management natively, without requiring additional plugins.
Customer Self-Service Portal — Customers can view licenses, download files, manage device activations, and manage subscriptions independently.
REST API & WP-CLI — A REST API with 60+ documented endpoints, extendable via the Advanced API add-on (full CRUD, WP-CLI commands) for external integrations.
Self-Hosted Update Delivery — The Update Server extension turns a WordPress site into a license-verified, self-hosted update server for plugins and themes.
Pros & Cons
Pros
Core DDLS plugin is free with no stated limits on products, licenses, or customers
Self-hosted licensing and update delivery keep customer and product data under the vendor's own control rather than a third-party marketplace
Modular paid extensions let buyers pay only for the features they need, with bundle discounts of up to 40%
REST API with 60+ documented endpoints plus WP-CLI support for scripting and external integrations
Cons
Deep WordPress/WooCommerce dependency means it isn't usable outside that ecosystem
Buying the full extension set individually can run to roughly €700+/year, though the All Access bundle caps this at €449/year
Public information about the company's team size, history, and support SLAs is limited beyond the DMSI website itself
