All the essential Qt tools for all stages of Software Development Lifecycle: planning, design, development, testing, and deployment.
Visit qt.ioWe analyzed Qt.io page load time and found that the first response time was 308 ms and then it took 2.8 sec to load all DOM resources and completely render a web page. This is a poor result, as 50% of websites can load faster.

Our browser made a total of 76 requests to load all elements on the main page. We found that 3% of them (2 requests) were addressed to the original Qt.io, 46% (35 requests) were made to D3hp9ud7yvwzy0.cloudfront.net and 8% (6 requests) were made to Google.com. The less responsive or slowest element that took the longest time to load (558 ms) relates to the external source Static.xx.fbcdn.net.
Page size can be reduced by 1.1 MB (48%)
2.2 MB
1.2 MB
In fact, the total size of Qt.io main page is 2.2 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 75% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Javascripts take 946.5 kB which makes up the majority of the site volume.
Potential reduce by 73.1 kB
HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 73.1 kB or 84% of the original size.
Potential reduce by 19.7 kB
Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Qt images are well optimized though.
Potential reduce by 653.1 kB
It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 653.1 kB or 69% of the original size.
Potential reduce by 326.8 kB
CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Qt.io needs all CSS files to be minified and compressed as it can save up to 326.8 kB or 88% of the original size.
Number of requests can be reduced by 42 (65%)

The browser has sent 65 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Qt. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 29 to 1 for JavaScripts and from 8 to 1 for CSS and as a result speed up the page load time.

Open Graph description is not detected on the main page of Qt. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
