Perpetual License

Each license covers one Erdikon instance and is bound to a specific domain. There are no storage limits.

The perpetual license gives you the right to use Erdikon indefinitely. You can continue using it without renewing the license or paying for a maintenance contract.

Updates for one year are included. Additional updates can be purchased through a maintenance contract for €195 per year.

If you install an update without a maintenance contract after the included updates have ended, your license does not cover that update. Erdikon then shows a warning to administrators for 30 days. After that, all users see the warning, and Erdikon blocks access through external interfaces such as MCP and the API. The web interface keeps working.

As long as you do not install such updates, you keep using Erdikon without restrictions.

Erdikon verifies your license locally, without contacting the license server. You therefore do not need an internet connection for license verification.

Erdikon connects to the license server in only two cases. When you buy a license from within the app, Erdikon receives the license key from the license server. While a subscription or maintenance contract is active, Erdikon also updates the key automatically through the license server.

You can find the full license terms in the Erdikon License. The article «Source-Available at Erdikon» explains what the license allows and how it differs from open source.

With the perpetual license, end-user support is charged at €195 per hour according to effort.

If you like, I install and operate Erdikon on your infrastructure and support you with technical support. You can find the prices on the «Services» page.
