VoltTest is a performance and load testing platform for PHP and Laravel developers, powered by a Go engine that runs each virtual user as a lightweight goroutine, using under 50 MB of memory per 1,000 VUs. Run tests locally from your terminal or switch to cloud mode to distribute load across 24 AWS regions scaling to over 10 million concurrent virtual users. The free tier includes 500 VUs, 10-minute tests, and a real-time metrics dashboard with P50, P95, and P99 latency percentiles — no credit card required.

From 0 to 10k users in seconds.

Laravel Package Available

First-Class Laravel Support

Seamlessly integrate performance testing into your Laravel workflow. Our dedicated package brings the power of VoltTest directly to Artisan.

Automatic Route Discovery

Automatically generate tests based on your defined routes.

Artisan Commands

Create, run, and manage tests using familiar CLI commands.

Sessions & CSRF

Cookies and sessions handled per virtual user. CSRF is one call — extractCsrfToken().

Security & data handling

What happens to your data during a test

The short version for whoever signs off on the tool. The dashboard and API are served over HTTPS, passwords are hashed with bcrypt, and Paddle handles payments, so card details never reach us.

Your target’s data

Response bodies are read in memory for assertions and value extraction, then discarded. Results keep timings, status codes, payload sizes, error messages and a sample of request URLs.

Where tests run

Cloud runs start fresh AWS instances in the regions you pick, from 24 available, and terminate them when the run ends. Local runs execute on your machine; the SDK only reaches out to download the engine binary.

Where API keys live

Your VoltTest key stays in your own environment (VOLTTEST_API_KEY in Laravel’s .env) and is shown once at creation. We store only a SHA-256 hash and a short prefix. Keys can be set to expire and deleted at any time.

FAQ

Frequently Asked Questions

Is VoltTest free to use?+

Yes. The free tier includes 500 concurrent virtual users, 10-minute test duration, 5,000 VU-hours per month, and full access to the real-time metrics dashboard. No credit card is required to sign up or start testing.

Does VoltTest work with Laravel?+

VoltTest has a dedicated Laravel package with Artisan commands for generating test stubs (volttest:make) and running tests (volttest:run). It auto-discovers your application routes, handles CSRF tokens and session cookies, and supports both local headless execution and cloud mode.

How fast is the VoltTest engine?+

The Go-powered engine uses under 50 MB of memory per 1,000 VUs. Each virtual user runs as a lightweight goroutine, enabling the engine to scale to 10 million or more concurrent users without JVM overhead.

What is the difference between local and cloud testing?+

Local (headless) mode runs tests from your terminal or CI/CD pipeline with no cloud dependency — ideal for development and pre-merge checks. Cloud mode distributes load across dedicated instances in 24 AWS regions, scaling to millions of concurrent users with a live dashboard, per-region metrics, and run comparison.

How does VoltTest compare to k6, JMeter, or Locust?+

VoltTest lets PHP and Laravel developers write load tests in their own language — no Java, Go, Python, or YAML required. Install via Composer, define scenarios with a fluent PHP API, and run locally or in the cloud. The Go engine matches or exceeds the throughput of alternatives while the Laravel package provides framework-native integration that general-purpose tools lack.
