Two Ways to Test

Local or cloud. Same SDK.

Start with headless mode on your machine, then flip to cloud when you need real scale. Your test code stays the same.

Headless Mode

Local · CI/CD · Open Source

  • Run from your terminal — no cloud needed
  • Works with PHP SDK & Laravel package
  • Instant CLI metrics with P50/P95/P99
  • Perfect for CI/CD pipelines
  • Open-source PHP SDK & Laravel package

Cloud Mode

Managed · Multi-node · Free tier

  • Scale to millions of concurrent VUs
  • Rich web dashboard with live charts
  • Per-scenario & per-step breakdowns
  • Multi-node distributed testing
  • Multi-region global load testing

Try cloud free

Same test code. Switch to cloud with one flag: $volt->cloud($apiKey)->run() or php artisan volttest:run --cloud

Cloud Mode

See everything. Miss nothing.

Test from 5+ global regions, compare runs side by side, and let smart insights surface what matters — all in one dashboard.

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 delivers 275 requests per second per virtual user using 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 5+ global 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.
