It is indexed under Mobile App Frameworks.","source":"https://www.qt.io","question":"What is Qt?","confidence":0.6},{"answer":"Qt does not publish its prices. Pricing is quoted on request, across 2 plans (Extended Security Maintenance and Premium Security Maintenance), 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.qt.io","question":"How much does Qt cost?","confidence":0.6},{"answer":"Qt supports the web and iOS. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://www.qt.io","question":"What platforms does Qt support?","confidence":0.6},{"answer":"Yes. Qt can be deployed cloud / SaaS, hybrid and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://www.qt.io","question":"Can Qt be self-hosted?","confidence":0.6},{"answer":"We have confirmed 4 integrations for Qt, including Figma, Axivion, Chromium and Reynolds & Moore.

Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Qt not holding them. Always confirm compliance directly before you rely on it.","source":"https://www.qt.io/ja-jp/blog/security-advisory-cve-2026-15037-xml-injection","question":"What security certifications does Qt have?","confidence":0.7},{"answer":"Qt is available worldwide.

Applications run using the operating system's native WebView component, resulting in minimal download sizes while maintaining full system-level access through a secure inter-process communication layer. It is indexed under Mobile App Frameworks.","source":"https://tauri.app","question":"What is Tauri?","confidence":0.6},{"answer":"Tauri is open source, so it can be self-hosted and used at no licence cost.
