Gatling vs Selenium: What are the differences?

What is Gatling? open-source load testing framework based on Scala, Akka and Netty. Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support..

What is Selenium? Web Browser Automation. Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.

Gatling belongs to "Load and Performance Testing" category of the tech stack, while Selenium can be primarily classified under "Browser Testing".

Gatling and Selenium are both open source tools. It seems that Selenium with 14.9K GitHub stars and 4.97K forks on GitHub has more adoption than Gatling with 4.3K GitHub stars and 918 GitHub forks.

According to the StackShare community, Selenium has a broader approval, being mentioned in 777 company stacks & 443 developers stacks; compared to Gatling, which is listed in 21 company stacks and 14 developer stacks.
