8 of Top 10 Fortune 500 use Qt
Qt is the software development framework of choice by engineers in over 70 industries worldwide for creating, building and deploying millions of connected embedded devices and applications. They chose Qt because it’s intuitive, cross-platform and saves time. When you develop with Qt, you create more, code less and deploy everywhere — and ahead of the rest.
From your smart home, to the car you drive, and the devices you use at work, Qt is there.
