About

Gatling is a high-performance load testing platform designed for developers and teams, providing continuous performance intelligence and automated load testing capabilities throughout the software lifecycle.

Best for

  • Load Testing scenarios across typical web and service stacks
  • Teams that prefer open-source licensing and self-hosting options
  • Groups comfortable scripting in Java, Scala, Kotlin

Not the best fit when

  • Teams unwilling to operate generators, results storage, and scaling

Architecture and concurrency

Gatling is commonly operated as self-hosted software with scenario authoring in Java, Scala, Kotlin. Concurrency and distribution depend on how you size workers or injectors.

Frequently asked

ANSWER-SHAPED
Who is Gatling for?

Gatling is best for engineers designing load, stress, and performance tests for web and service systems. It is open source, so teams can self-host and extend it. Vendor: Gatling Corp.. Deployment model: self-hosted. Free open-source core; commercial platform available. Confirm details against the official site and a short proof-of-concept in your environment.

How does Gatling differ from Apache JMeter?

Compared with Apache JMeter, scripting centers on Java, Scala, Kotlin rather than Java, Groovy. Gatling lists protocols HTTP, HTTPS, WebSocket, SSE, JMS; Apache JMeter lists HTTP, HTTPS, JDBC, JMS, FTP, TCP. Status is active versus active. Use the Test Rig to compare full specs side by side before a proof-of-concept.

What scripting language and concurrency model does Gatling use?

Gatling uses Java, Scala, Kotlin for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Windows, macOS, Linux. Protocols: HTTP, HTTPS, WebSocket, SSE, JMS. Match these to how your team already authors tests and which systems you must drive under load.

What is the cloud or enterprise path for Gatling?

Gatling is primarily self-hosted; teams typically run generators on their own machines, CI runners, or private cloud. Plan for generator capacity, network access to targets, and result storage yourself. As open source, commercial support or hosted siblings may exist separately. Check the official site. Pricing note: Free open-source core; commercial platform available.

What are known limitations of Gatling?

Gatling limitations to weigh: self-hosted tools require you to provision, scale, and observe load generators yourself. Status: active. Always validate against your target protocols and scale with a proof-of-concept. Confirm details against the official site and a short proof-of-concept in your environment.
