Skip Gatling AI Assistant for VS Code if you don't use Gatling for performance testing or you work in an IDE other than VS Code, as the extension's value is tightly bound to that ecosystem.
You must supply your own LLM API key, and usage incurs costs based on the model and token volume, which can add up for large or frequent generations.
The Free tier (with BYO-LLM) is ideal for individual developers and small teams comfortable with API costs. Compared to paid performance testing tools, you save on licensing but may spend more on LLM usage at scale.
In short
Gatling AI Assistant for VS Code — AI-powered Gatling test creation in VS Code with BYO-LLM. Best for Performance test engineers writing Gatling simulations, Developers new to performance testing, Teams requiring BYO-LLM for compliance or security. Free to use.

About Gatling AI Assistant for VS Code
Gatling AI Assistant for VS Code is a plugin that brings AI-powered performance test generation directly into your IDE. It helps developers create, explain, and optimize Gatling simulations without leaving VS Code. The assistant supports multiple languages and allows you to bring your own large language model (BYO-LLM) from providers like OpenAI, Anthropic Claude, and Azure OpenAI, keeping your code and data secure. Designed for developers already using Gatling or looking to adopt performance testing, this tool accelerates test creation by generating code from natural language descriptions. It can also analyze existing simulations to explain their logic or suggest optimizations. The AI understands Gatling's domain-specific language and best practices, making it easier to write effective tests. What sets it apart is the developer-first, transparent approach. You control which model is used, and no code is sent to external servers without your consent. The assistant is deeply integrated into the VS Code editor, providing inline suggestions, explainability, and refactoring capabilities. It's not a chatbot—it's a contextual pair programmer for performance testing. For teams and enterprises, the BYO-LLM model addresses compliance and security concerns, as sensitive test scenarios never leave your infrastructure. The tool is free to use (you pay only for your chosen LLM API usage), making it accessible for both individual developers and large teams.
Behind the Verdict
Gatling AI Assistant for VS Code is a niche but powerful extension for anyone who writes Gatling performance tests. Its BYO-LLM approach is a standout, giving you control over which model processes your code—a big win for teams with strict data governance. The tool shines in generating test code from plain English, explaining legacy scripts, and suggesting optimizations right inside the editor. For a new team member, it can turn a cryptic Scala test into a readable explanation in seconds. The free price point (you cover your own API costs) makes adoption a no-brainer for individual developers. However, its value is tightly coupled to using Gatling and VS Code; teams on other IDEs or test frameworks will get little use. The quality of suggestions depends on the underlying LLM, so results vary. If you're already invested in Gatling, this extension removes a lot of the boilerplate and learning curve, making it a practical addition to your workflow.

Models Under the Hood
as of 2026-08-18
Limitations
- Requires a valid API key from a supported LLM provider (OpenAI, Anthropic, or Azure) which incurs usage costs.
- The AI's suggestions are limited by the quality of the underlying model and may not always produce optimal test scenarios.
- There is no free hosted model; you must bring your own.
- The extension is only available for VS Code.
