⚡ Programming Languages

Programming languages are computer languages composed of instructions, syntax, and rules used by developers to create software such as applications and websites.

According to our research, programming languages are detected on 86.9% of all websites.
24.4% of these sites use only one programming language, 71.7% use two, and 3.9% use three or more simultaneously.

We only track the programming languages used to build websites. For example, JavaScript widgets are all over the web, so we only list JavaScript where we believe it was used directly to build the backend or frontend.
