Licensing

Kitto^x uses an Open Core licensing model with two tiers:

Component	License	Commercial use
Core (all controllers, routing, database, auth)	Apache 2.0	Free for any use
Enterprise Modules (Chart, Calendar, Map, Dashboard)	AGPL-3.0 / Commercial	Free for open-source apps; license required for closed-source
KIDEx (Visual IDE)	Commercial only	License required

Core — Apache 2.0

All source files in Kitto^x Core are licensed under the Apache License, Version 2.0. You may use, modify, and distribute them for any purpose — commercial or non-commercial — without restriction.

Enterprise Modules — AGPL-3.0 / Commercial

Enterprise modules are dual-licensed:

1. AGPL-3.0 — free for applications released under a compatible open-source license with full source disclosure (including SaaS/web apps accessed over a network).
2. Ethea Commercial License — for proprietary/closed-source applications. Removes all copyleft requirements. Contact info@ethea.it for pricing.

Enterprise modules include: Kitto.Html.ChartPanel, Kitto.Html.CalendarPanel, Kitto.Html.GoogleMap, Kitto.Html.Dashboard, and their attribute-routed data handlers (Kitto.Web.Handler.Chart/Calendar/Map). These are bundled in the Kitto.Web.Enterprise umbrella unit.

KIDE^x — Commercial only

KIDE^x (the Kitto^x Visual IDE) is not included in the open-source repository and requires a commercial license from Ethea S.r.l.

License activation

KIDE^x and the bundled MCP-KittoX server are protected with a single machine-bound license. An unregistered copy runs in trial/limited mode and shows its status in the title bar and splash screen; a registered copy shows Software registered to "<your company>" (<your developer email>).

To activate:

1. Open the License Manager dialog (offered automatically when an unregistered copy starts).

2. Fill in the two mandatory fields:

   • Company Name — your organization name.
   • Enter your developer email to obtain the license — the developer email address the license will be issued to (validated for correct format).

   The dialog also displays, read-only, the Machine Id (a fingerprint of this computer) and the Serial Number. Press Show request to copy a ready-to-send activation request to the clipboard, then send it to Ethea at support@ethea.it.

3. Ethea returns your release codes (activation codes) for that machine — one line per key, for example:

   MK=56B1-5A2B-9A41-C504
   IK=B916-00ED-027C-543F
   UN=2D56-06B9-3605-8965

   Paste them into the Activation box and press Activate Product. On success the dialog confirms Registration Complete.

Where the license is stored — and why multiple versions coexist

Since version 4.0.13 the license is stored in the Windows registry, under:

HKEY_CURRENT_USER\Software\Ethea\KIDEX

This replaces the legacy Registration.ini file that used to sit next to KIDEX.exe. The registry storage is per-user: it needs no administrator rights, is Terminal-Server / multi-user friendly, and is not tied to the folder the executable runs from.

Register once, run every version

Because the registration lives in a single per-user registry key (not in a file inside each install folder), you can install and run several versions of Kitto^x / KIDE^x side by side on the same machine — they all read the same key, so a single activation unlocks every installed version (and the same key also unlocks MCP-KittoX). The license is bound to the machine, so it is valid for each user only on the computer it was issued for.
