Simple, transparent pricing

The free plan includes up to 10 nodes per network, 2 projects, all component types (pumps, valves, tees, reducers, etc.), the incompressible solver with water and air, save functionality, and PNG export. EPANET and JSON import are also included.

Yes, you can upgrade to Pro at any time from your Settings page. Your subscription is managed through Lemon Squeezy, where you can also downgrade or cancel. If you cancel, you retain Pro access until the end of your current billing period.

There is no separate trial — the free plan itself lets you evaluate the core simulation engine, all component types, and the visual editor. The main limitations are network size (10 nodes), solver type (incompressible only), and fluid selection (water and air). Upgrading to Pro removes these limits.

Payments are processed by Lemon Squeezy, our merchant of record. They accept all major credit and debit cards (Visa, Mastercard, American Express) and handle EU VAT automatically. Prices shown are in EUR.
