Qt FAQ
Common questions about Qt, answered from independent, dated evidence.
What is Qt?
Qt provides libraries, APIs, and development tools that enable developers to create user interfaces and applications running across desktop computers, mobile devices, web platforms, and embedded systems from a unified codebase. It is indexed under Mobile App Frameworks.
Source: https://www.qt.io
How much does Qt cost?
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.

What platforms does Qt support?
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
Can Qt be self-hosted?
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
What does Qt integrate with?
We have confirmed 4 integrations for Qt, including Figma, Axivion, Chromium and Reynolds & Moore. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://www.qt.io
What security certifications does Qt have?
We have independently confirmed ISO 27001 for Qt. 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.

Where is Qt available?
Qt is available worldwide. The vendor is headquartered in Finland.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Qt, not the verdict.
