XAD licensing

XAD licensing, in plain words.

XAD is open source under AGPL-3.0, for open-source projects, research and evaluation. The AGPL is not suitable for enterprise settings: for use in your organisation you need a separate commercial licence from us. Here are the short answers.

Can we use XAD under the AGPL inside our company?

To evaluate it and for research, yes. For production use in your organisation, no: the AGPL is not suitable for enterprise settings, and you need a separate commercial licence from us, an XAD subscription.

What does the AGPL require?What the AGPL requires is set out in its licence terms.
Does this cover QuantLib with AAD?

Yes. QuantLib with AAD, in C++ and its Python bindings, is open source under the AGPL, and the same applies: for use in your organisation you need a commercial licence from us. QuantLib on its own keeps its own BSD licence.

What does an XAD subscription add?

A commercial licence in place of the AGPL, for use in your organisation. IP indemnity, updates, support and stable versions for regulated deployments, the XAD validation pack, with a validation report for your model-risk team on request, and clear terms for audit and procurement. Enterprise adds code generation, a named support engineer and service levels. Annual, per seat or per site.

Are XAD's tests open source too?

XAD's unit tests are public and stay public in the open-source repository. The XAD validation pack (edge-case, stress and performance-regression suites, reconciliation against QuantLib and real pricers, and a validation report for model-risk reviews on request) is private and comes with every Commercial and Enterprise subscription.

How do we check where we stand?

Book a licence check: a free, confidential call. Tell us what XAD is in and where it runs, and we tell you which licence you need.

A summary, not legal advice: the licence text decides. The AGPL-3.0 text on GitHub.

Procurement

For procurement and vendor risk

The first questions of a vendor review, answered before the questionnaire arrives.

SupportCommercial and Enterprise include updates, fixes and support from the engineers who build and maintain XAD, with direct access to them. Enterprise adds a named support engineer and service levels. Support terms are written into the subscription agreement and agreed before signature. What a site isA site is one legal entity using XAD in one country: every developer, build machine and server of that entity there is covered. Each further entity or country is a further site, and one agreement can list several. Evaluating the closed partsXAD itself you evaluate from its public source, under the AGPL. Code generation is not open source: you evaluate it on your own code in the free speed-up estimate, under a mutual NDA, inside your bank with our engineer, before anything is bought. ReferencesReference calls with existing clients are arranged at shortlist stage. ContinuityThe source is public, so continuity does not depend on us: XAD's full source, history and unit tests are on GitHub under AGPL-3.0, and your team can build and maintain it from there whatever happens to Xcelerit. Code we write for you is yours. Security and due diligenceSecurity questionnaires, vendor-risk and DDQ requests: security@xcelerit.com. On request: company details, insurance, a security overview and the XAD open-source supply chain.
