I like that Gatling is lightweight and easy to use. There are many options available for script preparation, which allows us to work fast and achieve accurate results. The initial setup was smooth, making it easier for us to transition to using Gatling for performance testing activities. Review collected by and hosted on G2.com.

We have an issue with the report file not being generated in Excel format. Instead, Gatling reports are provided in a different file format. It would be better if Gatling could generate reports in Excel format as well. Review collected by and hosted on G2.com.

It integrates well with my existing Karate framework. Can easily run load tests and produces reports with rich performance insights. Review collected by and hosted on G2.com.

Nothing much to add, really. It’s one of the best tools I’ve used so far for performance testing, and it has worked well for what I needed. Review collected by and hosted on G2.com.

Writing performance tests as a code, gradle support.

Very good documentation and a very useful community.

Great memory management, easy support of tens of thousands of users. Review collected by and hosted on G2.com.

I still haven’t found a perfect way to debug the tests yet. Review collected by and hosted on G2.com.

It has great capabilities and features for measuring load and performance when testing our infrastructure. Review collected by and hosted on G2.com.

Pricing is bit on a higher side and we have less community till date , we can have ways to onboard customer Review collected by and hosted on G2.com.

Its really good tool for load testing tool i actually use it for my old legacy app and it really helped me to improve the app performance. Review collected by and hosted on G2.com.

It’s difficult for an end user to understand the UI, so it could be improved in that area to make it clearer and easier to use. Review collected by and hosted on G2.com.

I like that Gatling made performance testing easy for my Kotlin backend application. It helped us achieve our tier1 project's SLA and identify crucial breaking points under stress testing. The tool's ease of use and the powerful in-built functionalities fit my use case perfectly. I appreciate how exceptionally it works to test systems in bottleneck traffic. Also, the initial setup was very easy and understandable. Review collected by and hosted on G2.com.

Gatling’s biggest strength, in my experience, is the developer experience when building test scripts. A lot of effort has clearly gone into the fluent style of writing tests, and even though the scenarios are written as code, they remain easy for humans to read and understand.

There’s a lack of automatic correlation detection for test scripts, which makes the process more manual than it needs to be. Review collected by and hosted on G2.com.

I use Gatling for testing in both my previous and current company, and I really like their support. The switch from using Scala to TypeScript for writing tests has been a positive experience for me. The DSL (domain-specific language) that Gatling has is very intuitive, making it easy to use. I appreciate that it's easy to use, especially compared to tools like JMeter, and I like that you have something more tangible in the code form. The fact that developers can easily jump in and manage changes since it's code-based is great. I find the syntax clear, and the reporting feature is very user-friendly, providing a history of load tests that is quite helpful. The support for languages and clear syntax makes writing tests easier, even for people who might have never coded before. I also find the reporting crucial for quickly getting the information I need and spotting bottlenecks or slow requests at a glance. The feature that allows comparisons between different runs is something I appreciate very much. Additionally, the community support is great. I also recommended Gatling at my current company because I liked it. Setup is now easier thanks to moving from Scala to Java and TypeScript support, which I think helps in facilitating the setup. There's also a recording tool that can get you started quickly. I really like Gatling, think it's a great tool, and appreciate the great support from the community.

I think maybe their documentation could be a bit more. It is good, but I think it could be improved. Sometimes, you get confusing information that might not be suitable for your case. I think that could be improved. Before, in my previous company, when I used their reporting, I had some bugs in terms of a layout break. If I have a long endpoint written, then the layout would break and basically make the report not useful to me. So I have to make workarounds there. Review collected by and hosted on G2.com.

I like the flexibility I get in implementing data generators (feeders). This allows for representative and sufficiently random data that ultimately gives meaningful performance test results.

I also like the simulation run management and history offered by the enterprise product which lets non-engineers to access and use the results directly.

The technical documentation is an ever-evolving artifact but in its current state it is useful and well structured and helps newcomers create effective simulations, not just "hello world" versions. Review collected by and hosted on G2.com.

Some of our integrations (e.g. with Github workflows) are brittle, although I should add that they are improving both the integrations themselves and the relevant documentation. Review collected by and hosted on G2.com.

Creating test cases was a breeze, and I didn’t have to bother with a UI like JMeter. Review collected by and hosted on G2.com.

Scala documentation and support are sometimes inaccurate or not detailed enough. Review collected by and hosted on G2.com.
