At Crisp, we trust that performance are serious matters. It's why Crisp is one of the fastest providers on the market. Crisp is only 130KB to download. Less than most JPG images.

Most webmasters are using SEO tools to analyze website assets. These tools are outdated and are not considering all optimizations that Crisp is using.

Our actions to optimize performances

Crisp is loaded asynchronously to not slow down and impact your SEO. It means that Crisp chatbox is loaded after anything else has been loaded on your website.

2 - Distributed / Low-latency chat servers

We have servers all around the world to not impact end-users if here are on a different continent. We have dedicated endpoints in the following cities/countries

London

3 - Distributed CDN using HTTP2

Crisp is using latest HTTP standard to serve your content. It reduces the amount of TCP handshakes and leads to 50% faster requests compared to HTTP 1.1

Overall, Crisp is using a CDN is accelerate CDN distribution. It means that it downloads the assets (CSS, Images, Javascript) in the nearest location.

4 - Assets are compressed

Crisp is compressing assets using GZIP and Javascript/CSS minification. Every single byte matters

5 - Fonts are optimized using sub-ranges

Instead of downloading a UTF-8 font containing all characters, Crisp is loading only what is required. For instance, if you are using a Latin locale, we load only Latin chars.

6 - We load only the content needed

By default, Crisp is not loading MagicBrowse, Video calls libraries. It's loaded on the fly if you request a MagicBrowse.
