Pricing is quoted on request, across 2 plans (Free and Paid Plans), so the figure depends on your seat count and requirements. We record this as a pricing-transparency signal rather than guessing a number. Pricing changes often, so verify at source before relying on it.","source":"https://www.dalux.com/","question":"How much does Dalux cost?","confidence":0.6},{"answer":"We have confirmed browser-based access to Dalux. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.","source":"https://www.dalux.com/","question":"What platforms does Dalux support?","confidence":0.6},{"answer":"We have only confirmed a cloud / SaaS deployment for Dalux, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.","source":"https://www.dalux.com/","question":"Can Dalux be self-hosted?","confidence":0.6},{"answer":"We have independently confirmed GDPR for Dalux.

Always confirm compliance directly before you rely on it.","source":"https://www.dalux.com/","question":"What security certifications does Dalux have?","confidence":0.6},{"answer":"Dalux is available worldwide. Its primary markets are Denmark and Sweden. The vendor is headquartered in Denmark.","source":"https://www.dalux.com/","question":"Where is Dalux available?","confidence":0.75}]` | `[{"answer":"IfcOpenShell is an open source library and geometry engine for developing digital platforms in the built environment.

IfcOpenShell can be deployed cloud / SaaS and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://ifcopenshell.org/","question":"Can IfcOpenShell be self-hosted?","confidence":0.6},{"answer":"We have confirmed 10 integrations for IfcOpenShell, including Blender, Oracle P6, Microsoft Project, Asta PowerProject, IDS, BCF, bSDD and CityJSON, plus 2 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://ifcopenshell.org/","question":"What does IfcOpenShell integrate with?","confidence":0.6},{"answer":"Yes. IfcOpenShell is published under the LGPL-3.0 licence, a copyleft licence, so check its terms before embedding it in a closed-source product.
