CLASTIX End User Licence Agreement

Last updated: August 2026

PLEASE READ CAREFULLY BEFORE INSTALLING OR USING ANY CLASTIX SOFTWARE:

This End User Licence Agreement (Agreement) is a legal agreement between you (Licensee or you) and CLASTIX SRL of V. Francesco Caracciolo, 17, 80122 Naples, Italy (VAT: IT11183320966; REA: NA-1152378) (CLASTIX, us, our or we).

This Agreement governs your use of the CLASTIX software products described below. The terms applicable to each product differ, as set out in this Agreement and summarised here:

  • kMetal: a proprietary bare-metal Kubernetes platform, licensed commercially under this Agreement together with a separate Commercial Agreement (as defined below).
  • Kamaji: an open-source Kubernetes control plane manager owned by CLASTIX and licensed under the Apache License, Version 2.0. Use of Kamaji is governed solely by that open-source licence. Commercial support for Kamaji is governed by a separate written support agreement.
  • Capsule: an open-source Kubernetes multi-tenancy framework donated by CLASTIX to the Cloud Native Computing Foundation (CNCF). Use of Capsule is governed by the applicable CNCF project licence. CLASTIX acts as a founding contributor and imposes no additional licence terms on its use.

We license use of kMetal to you on the basis of this Agreement. We do not sell kMetal to you. We remain the owners of kMetal and its associated documentation at all times.

The software specification and system requirements for kMetal are detailed in the user documentation, accessible at docs.clastix.io, which may be updated from time to time.

IMPORTANT NOTICE:

  • BY INSTALLING, DEPLOYING, OR USING kMetal, YOU AGREE TO THE TERMS OF THIS AGREEMENT, WHICH WILL BIND YOU AND YOUR EMPLOYEES AND CONTRACTORS. THE TERMS OF THIS AGREEMENT INCLUDE, IN PARTICULAR, LIMITATIONS ON LIABILITY IN CLAUSE 6.
  • IF YOU DO NOT AGREE TO THESE TERMS, YOU MAY NOT INSTALL OR USE kMetal.

You should retain a copy of this Agreement for future reference.

1. Grant and scope of licence (kMetal)

1.1 kMetal is proprietary, commercially licensed software. It is not open-source, freeware, or shareware. The commercial terms governing your use of kMetal – including pricing, the number of licensed CPU sockets, permitted deployment environments, and subscription duration – are set out in a separate written agreement between you and CLASTIX (the Commercial Agreement). In the event of any conflict between this Agreement and the Commercial Agreement, the Commercial Agreement shall prevail in respect of commercial terms.

1.2 Subject to the terms of this Agreement and upon execution of a Commercial Agreement, we grant you a non-exclusive, non-transferable licence to install and use kMetal and its associated documentation (Documents) for the scope and duration defined in your Commercial Agreement.

1.3 In accordance with your Commercial Agreement, you may:

(a) download, install, and use kMetal on the number of CPU sockets and within the environments specified in your Commercial Agreement;

(b) make up to two copies of kMetal for backup or disaster recovery purposes only, provided you maintain a record of such copies and take reasonable steps to prevent unauthorised access; and

(c) receive and use any updates, patches, or corrections to kMetal provided by us during your active subscription term.

1.4 Proof of Concept use. Where CLASTIX has agreed in writing to conduct a Proof of Concept (PoC) engagement with you prior to the execution of a Commercial Agreement, we grant you a limited, non-exclusive, non-transferable, revocable licence to use kMetal solely for the purposes, in the environments, and for the duration agreed with your CLASTIX representative. PoC use is provided “as is” without warranty, support, or indemnification of any kind, and may be terminated by us at any time on written notice. All other terms of this Agreement apply to PoC use.

1.5 Open-source adopters. CLASTIX acknowledges that some users may independently deploy Kamaji and/or Capsule under their respective open-source licences – including as a precursor to a commercial engagement with CLASTIX. Such use is governed exclusively by the applicable open-source licence and does not create any commercial obligation, warranty, or licence grant from CLASTIX in respect of kMetal. The terms of this Agreement and any associated commercial obligations arise only upon execution of a Commercial Agreement.

2. Open-source products

2.1 Kamaji. Kamaji is an open-source project owned by CLASTIX and made available under the Apache License, Version 2.0. A copy of that licence is available at https://www.apache.org/licenses/LICENSE-2.0. Your use of Kamaji is governed solely by the Apache 2.0 licence and this Agreement does not apply to it. No licence fees are payable for the use of Kamaji as open-source software. Commercial support services for Kamaji are available from CLASTIX and, if engaged, are governed by a separate written support agreement.

2.2 Capsule. Capsule is an open-source Kubernetes multi-tenancy framework originally created by CLASTIX and donated to the Cloud Native Computing Foundation (CNCF). Capsule is a CNCF-hosted project and CLASTIX acts as its founding contributor. Your use of Capsule is governed solely by the applicable CNCF project licence. CLASTIX imposes no additional licence terms on the use of Capsule. For more information, visit https://projectcapsule.dev.

3. Restrictions

In respect of kMetal, except as expressly set out in this Agreement or your Commercial Agreement, or as permitted by applicable law, you undertake:

(a) not to copy kMetal or its Documents except where such copying is incidental to normal use or where necessary for backup or operational security as permitted under Clause 1.3(b);

(b) not to use kMetal beyond the scope of use defined in your Commercial Agreement, including with respect to the number of licensed CPU sockets and permitted deployment environments;

(c) not to rent, lease, sub-licence, loan, translate, merge, adapt, vary, or modify kMetal;

(e) not to disassemble, decompile, reverse-engineer, or create derivative works based on kMetal, or otherwise attempt to derive its source code, except to the extent that such actions cannot be prohibited because they are essential for achieving inter-operability with another software program under applicable Italian and EU intellectual property legislation (including Article 64-quater of Legislative Decree No. 518/1992 implementing the EU Software Directive, as amended), and provided that information obtained during such activities:

(i) is used only for the purpose of achieving inter-operability;

(ii) is not disclosed to any third party without our prior written consent; and

(iii) is not used to create software substantially similar to kMetal;

(f) to supervise and control use of kMetal and ensure that it is used by your employees, contractors, and representatives in accordance with the terms of this Agreement;

(h) not to provide or otherwise make kMetal available, in whole or in part, to any person other than your employees or authorised contractors without our prior written consent;

(i) to comply with all applicable technology control or export laws and regulations; and

(j) not to use kMetal for any purpose which may be deemed immoral, illegal, offensive, threatening, abusive, or otherwise harmful.
