Editorial Verdict
Best for
Performance test engineers writing Gatling simulationsDevelopers new to performance testingTeams requiring BYO-LLM for compliance or securityQA engineers automating load test creationDevOps engineers integrating testing into CI/CD
Not ideal for
Teams not using Gatling or VS CodeUsers wanting a standalone AI chatbot (it's IDE-embedded)Those needing non-performance test generation (e.g., unit tests)Users who prefer closed-source, all-in-one AI toolsBeginners without any knowledge of Gatling's DSL
Gatling AI Assistant is a focused, developer-friendly tool that genuinely speeds up performance test creation in VS Code. Its BYO-LLM model respects user privacy and compliance needs, though the free tier requires your own API key. If you're already invested in Gatling, this extension is a no-brainer; otherwise, the value is tied to the Gatling ecosystem.

Recurring strengths
- +AI generates Gatling simulations from natural language prompts directly in VS Code.
- +Supports JS, TS, Scala, Java, and Kotlin for broad team compatibility.
- +BYO-LLM keeps sensitive code and data fully under your control.
- +Explains existing Gatling simulations to help onboard new team members.
- +Recommends optimizations for more realistic load patterns and better performance.
Recurring frustrations
- −Currently very little independent community feedback or real-world reviews.
- −Requires prior Gatling knowledge—not a tool for learning load testing from scratch.
- −BYO-LLM setup adds friction compared to all-in-one assistants like GitHub Copilot.
- −Only useful for developers already using or adopting Gatling for performance tests.
- −No built-in model; you must manage API keys and usage costs separately.

About Gatling AI Assistant for VS Code
FreemiumIntermediateNo APIPlugin
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 (JavaScript, TypeScript, Scala, Java, Kotlin) 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. This tool is designed for developers already using Gatling or looking to adopt performance testing. It accelerates test creation by generating code from natural language descriptions, and 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 exactly 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 individual developers and large teams alike.
Behind the Verdict
Should you use Gatling AI Assistant for VS Code? If you are already using Gatling for performance testing and VS Code as your editor, this extension is a significant productivity booster. It eliminates much of the boilerplate involved in writing simulation code and helps you quickly iterate on test scenarios. The BYO-LLM approach is a strong differentiator for organizations with data governance requirements, as you can keep all prompts and generated code within your own environment. However, if you are not in the Gatling ecosystem or prefer a tool-agnostic AI assistant, this extension may feel too narrow. It does not generate tests for other frameworks (e.g., k6, JMeter) and is limited to VS Code. Also, the requirement to supply your own LLM API key adds friction, and the assistant's suggestions depend heavily on the model's understanding of load testing. For teams already comfortable with Gatling, this tool is a clear win; for others, it's worth evaluating only if you plan to adopt Gatling.

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.
