Gatling AI Assistant for VS Code
A free VS Code extension that turns plain-English prompts into Gatling load-test simulations using your own LLM API key.
If Gatling is already in your stack and you write your simulations in VS Code, install this: it is listed at $0/mo, it respects your LLM provider choice, and the explain-an-inherited-simulation path earns its setup time on its own. The catch is total lock-in — no Gatling, no VS Code, no value. Compare it to Copilot or Cursor, which will draft a Gatling file but know nothing about load-test semantics, and to k6 or JMeter tooling if you are not committed to Gatling. Treat it as a domain specialist beside your general coding assistant, not a replacement for one.

Skip Gatling AI Assistant for VS Code if you do not write Gatling in VS Code — it is a VS Code-only extension, so JetBrains, CLI-only, and k6/JMeter/Locust teams get nothing from it.
The extension is listed at $0/mo, but every prompt is billed by your LLM provider per token, so heavy generation and refactoring cycles show up on your OpenAI, Anthropic, or Azure invoice.
Listed at $0/mo, which puts it below almost every paid performance-testing SaaS and below general coding assistants with a monthly seat fee — Copilot and Cursor both charge per seat. Your real spend is token usage on your own OpenAI, Anthropic, or Azure key, so cost scales with how much you generate rather than with headcount. For a team already paying for Gatling Enterprise, this is a small add-on next to that contract.
In short
Gatling AI Assistant for VS Code — A free VS Code extension that turns plain-English prompts into Gatling load-test simulations using your own LLM API key. Best for Gatling users who want AI help writing simulations inside VS Code, Engineers onboarding onto Gatling who need working examples fast, Teams that require prompts routed through their own LLM provider.

About Gatling AI Assistant for VS Code
Gatling AI Assistant for VS Code is a free editor extension that writes Gatling simulations from plain-English prompts without leaving your IDE. It is built for people already running Gatling — performance test engineers, QA leads, and DevOps engineers wiring load tests into CI — plus developers who know they should be load-testing but keep bouncing off Gatling's Scala/DSL learning curve. Instead of pasting snippets into a web chatbot, you describe the scenario and get Gatling code in the file you're editing. It covers more than first-draft generation. You can ask the assistant to explain a simulation you inherited, refactor legacy test code, or flag unrealistic load patterns before they burn a multi-hour test run. Generation is aware of the Gatling DSL and the language you name — JavaScript, TypeScript, Scala, Java, or Kotlin — so output lands closer to compilable Gatling than to generic HTTP-client pseudocode. The headline design choice is bring-your-own-key. You connect your own provider credentials for OpenAI, Anthropic Claude, or Azure OpenAI, so model choice, rate limits, and data-handling terms are set by you rather than by a third-party SaaS — usually the deciding factor for regulated teams. Common actions sit in the VS Code command palette, and the extension behaves like a contextual pair programmer rather than a chat sidebar. The extension itself is listed at $0/mo in the current pricing details; your only bill is whatever your LLM provider charges for the tokens you use. General-purpose coding assistants such as Copilot or Cursor will draft a Gatling file too, but they carry no grounding in load-test semantics — this is the narrower tool for that specific job.
Behind the Verdict
The interesting thing here is not the code generation — plenty of assistants will attempt a Gatling file. It is the scope of the job the extension claims: generate, explain, refactor, and critique. The explain path is the one with the least competition. Inherited load-test suites are notoriously opaque, and tooling that turns a Scala simulation into a plain-language description is genuinely useful during onboarding or an incident review. Generation is language-aware across JavaScript, TypeScript, Scala, Java, and Kotlin, which matters because Gatling's DSL is not identical in each. You also get project-wide analysis alongside per-file operations, command palette access to the common actions, and tunable generation parameters such as temperature and max tokens. The BYO-LLM model — OpenAI, Anthropic Claude, or Azure OpenAI — means your prompts, and the endpoint details inside them, travel to a provider you already have a contract with rather than to a new vendor. Where it is thin: it is a VS Code extension and nothing else, so JetBrains users and CLI-only workflows are outside the tent. It is also not a test runner, a dashboard, or a scheduler — Gatling Enterprise connections are surfaced through the extension, but the extension does not replace your execution and reporting layer. And generated simulations are drafts: the extension will not know your real traffic mix, so a reviewer still has to sanity-check think times, ramp shapes, and feeder data before anything runs against production-like infrastructure. Where it fits: a team with an existing Gatling investment, a VS Code standard, and either a compliance requirement to route prompts through their own model or simply a preference to pay token costs directly. Where it does not: teams on k6, Locust, or JMeter, anyone who wants one assistant covering all languages, and anyone expecting generated tests to run correctly without review.

Real-world workflow fit
Concrete scenarios for the personas Gatling AI Assistant for VS Code actually fits — and what changes day-one when you adopt it.
Open the simulation file, describe the checkout flow in the command palette, and let the extension draft the Gatling DSL in the language the project uses.
Outcome: A first working simulation in the open file within minutes, then hand-tuned — with token cost on the team's own LLM key rather than a new subscription.
Point the explain action at the legacy Scala simulations nobody on the team wrote and ask for plain-language summaries per file.
Outcome: The new hire understands what each scenario exercises before touching it, shortening ramp-up on a suite that would otherwise be reverse-engineered by hand.
Run the realism check over a simulation to surface unrealistic load patterns, then refactor the flagged sections ahead of the run.
Outcome: Obvious ramp and spike problems get caught before a multi-hour test run is spent on a scenario that would not have produced usable results.
Use Cases
- Draft a realistic Gatling simulation for a login endpoint from a plain-English description
- Explain a complex Gatling script to a new team member during onboarding
- Rework an existing simulation to smooth out server load spike patterns
- Refactor a Scala-based Gatling test to JavaScript for team consistency
- Build a parameterized test from an OpenAPI specification draft
- Flag unrealistic load patterns before committing hours to a test run
- Generate a first working Gatling file while learning the DSL
Models Under the Hood
as of 2026-09-01
Limitations
- Requires a valid API key from a supported LLM provider (OpenAI, Anthropic, or Azure), and that provider bills you for token usage separately from the extension.
- Suggestions are bounded by the quality of the underlying model and may not produce an optimal scenario.
- Generated tests are drafts — nobody should run them against production-like infrastructure without review of think times, ramp shapes, and feeder data.
- The extension is available only for VS Code, so JetBrains and CLI-only workflows are out of scope, and it does not replace your execution and reporting layer.

Setup time & first value
How long it actually takes to get something useful out of Gatling AI Assistant for VS Code — broken out by persona, not the marketing-page minute.
If you already have VS Code and a supported provider key (OpenAI, Anthropic, or Azure OpenAI), you install the extension and connect the key — first value in a single sitting by opening a simulation file and asking for a generation or an explanation. Teams that still need to agree which provider key and data terms apply will take longer on the internal approval step than on the install.
Switching to or from Gatling AI Assistant for VS Code
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hand-written Gatling simulations: keep the files where they are and use the explain and refactor actions to modernize them incrementally.
- →From pasting prompts into a web chatbot: move the same prompts into the editor so the generated Gatling code lands directly in the file you are editing.
- →From a general-purpose coding assistant: keep both, using the general assistant for surrounding application code and this extension for load-test semantics.
- ↗To Gatling Enterprise: keep your existing simulations and move execution, scheduling, and reporting to the hosted platform, using the extension connection for the authoring side.
- ↗To a general-purpose coding assistant: you lose the Gatling DSL grounding and the explain/refactor actions, and gain coverage of other languages.
