VoltTest vs LoadForge

A LoadForge alternative for PHP and Laravel teams

VoltTest is a PHP-first load testing platform with a Go engine and native Laravel integration. LoadForge is a hosted load testing platform built on Locust, where tests are written in Python. VoltTest wins on staying inside the PHP ecosystem, running locally without an account, and geographic reach; LoadForge wins on test-type breadth and platform maturity.

We built VoltTest because PHP and Laravel teams shouldn't need a second language to load test their applications. But LoadForge is a genuinely capable platform with excellent Laravel guides and a wider testing surface than ours. This page shows you where each tool wins.

The key differences

Both run multi-step scenarios at scale. Three decisions define where each one shines.

Language & where your tests live

VoltTest — PHP in your repo

$ composer require volt-test/laravel-performance-testing --dev
$ php artisan volttest:make Checkout --routes
Created tests/VoltTest/CheckoutTest.php
$ php artisan volttest:run Checkout

Tests are PHP classes committed alongside your application. They go through the same code review, the same CI, and the same version history as the code they exercise.

LoadForge — Python, in the platform

from locust import HttpUser, task
class WebsiteUser(HttpUser):
@task
def checkout(self):
self.client.get("/cart")

Tests are Locust scripts authored in the LoadForge web app. An AI wizard and Postman/Swagger import can generate them for you, so you may write little Python by hand — but the tests still live outside your repository.

The trade-off: VoltTest keeps load tests inside your PHP codebase, where Laravel's CSRF tokens, sessions and routes are already understood. LoadForge's generators get you to a first test faster, especially if you have an existing API spec to import.

Local execution & infrastructure

VoltTest — local or managed cloud

The headless engine runs on your own machine with no account, no API key and no network callback — on Windows, Linux or macOS. You get the same percentile report locally that you get in the cloud. When you need real scale, one line switches execution to managed infrastructure, with load generated from 24 AWS regions and split across several of them by weight in a single run.

LoadForge — hosted platform

LoadForge runs tests from 19 global regions with scheduling, GitHub integration, SLA thresholds and anomaly detection built in. There is no documented local or self-hosted mode — though because tests are Locust scripts, you can always run one with open-source Locust on your own machine, just without the LoadForge platform around it.

Scope & ecosystem

VoltTest — narrow and Laravel-native

HTTP and HTTPS load testing only, done thoroughly for PHP: Artisan commands, route-aware test generation, automatic CSRF and cookie handling, PHPUnit assertions for gating CI, and five extractor types for chaining requests. The PHP SDK and Laravel package are MIT-licensed and open source; the engine and platform are not.

LoadForge — broad and Locust-backed

Beyond HTTP load testing, LoadForge covers GraphQL, SQL, DoS resilience, site speed and accessibility auditing. Tests run on Locust, so you inherit an established open-source runtime and the Python libraries around it. The LoadForge platform itself is proprietary.

Make your choice

Two scripting languages, two philosophies about where tests belong. Here's each tool's honest scorecard — limitations included.

VoltTest

PHP-native load testing for Laravel teams

Strengths

  • Tests written in PHP and versioned in your repository
  • Laravel package with Artisan commands and route discovery
  • Automatic CSRF token and cookie/session handling
  • PHPUnit assertions for gating performance in CI
  • Runs locally with no account, or in managed cloud
  • PHP SDK and Laravel package are open source (MIT)

Limitations

  • HTTP/HTTPS only — no GraphQL, SQL, or accessibility testing
  • A single run splits across a limited number of regions, plan-dependent
  • Launched 2026 — newer platform, smaller community
  • No self-hosted platform — dashboard and history are managed only
  • Engine and cloud infrastructure are proprietary

Choose VoltTest if you…

  • Are a PHP or Laravel team testing HTTP endpoints
  • Want load tests reviewed and versioned with your code
  • Need Laravel CSRF, sessions and routes handled for you
  • Want to run tests locally before paying for anything

LoadForge

Hosted load testing built on Locust

Strengths

  • Broad test types — GraphQL, SQL, site speed, accessibility
  • AI-enhanced reporting with anomaly detection
  • AI wizard and Postman/Swagger import for test creation
  • Established platform with solid Laravel guides
  • Scheduling, GitHub integration and SLA thresholds
  • Runs on Locust — a mature open-source runtime

Limitations

  • Tests are Python — a context switch for PHP teams
  • Scripts live in the platform, not in your repository
  • No Artisan commands, route discovery, or PHPUnit integration
  • Laravel CSRF and session handling must be written manually
  • Hosted only — no documented local or self-hosted mode

Choose LoadForge if you…

  • Are comfortable with Python and Locust
  • Need test types beyond HTTP load, like GraphQL or SQL
  • Want scheduled recurring runs with SLA alerting
  • Prefer generating tests from an existing API spec

Common questions

Is VoltTest a good LoadForge alternative for Laravel teams?+
If your application is written in PHP, VoltTest removes a language boundary that LoadForge keeps. LoadForge tests are Locust scripts written in Python and authored in the LoadForge web app; VoltTest tests are PHP files installed with composer require volt-test/php-sdk, committed alongside your application code, and generated from your Laravel routes with the volttest:make --routes Artisan command. LoadForge remains the broader platform — it tests GraphQL, SQL, site speed and accessibility, well beyond what VoltTest covers. VoltTest focuses on HTTP and HTTPS load testing for PHP and Laravel teams, and generates that load from 24 AWS regions.
Do I have to write Python to use LoadForge?+
Not always. LoadForge runs Locust under the hood, so tests execute as Python, but the platform can also generate them for you through an AI wizard or by importing a Postman or Swagger collection. The practical difference is where the tests live: LoadForge tests are Python scripts managed in the LoadForge web app, so they sit outside your application repository and outside your language. VoltTest tests are PHP classes in your codebase, reviewed in the same pull requests and versioned with the code they test.
Can I run VoltTest load tests locally without a cloud account?+
Yes. The VoltTest engine has a headless mode that runs entirely on your own machine — no account, no API key, and no network callback. It runs on Windows, Linux and macOS, and prints a full report with P50 through P99 percentiles and error breakdowns. Concurrency is limited by your machine rather than by a plan. Adding cloud execution is a one-line change. LoadForge is a hosted platform with no documented local mode, although the underlying Locust script can of course be run with open-source Locust on your own — just without the LoadForge platform around it.
Is VoltTest open source like Locust?+
Partly, and it is worth being precise. The VoltTest PHP SDK and Laravel package are open source under the MIT license on Packagist and GitHub, so you can read, fork and extend the layer you write tests against. The Go engine, cloud infrastructure and dashboard are proprietary. LoadForge is the mirror image: the platform is proprietary, but the tests you write run on Locust, which is genuinely open source. If a fully open-source stack is a hard requirement, plain Locust — without either platform — is the honest answer.
What can LoadForge test that VoltTest can't?+
A fair amount. LoadForge covers websites, APIs, GraphQL, SQL, DoS resilience, accessibility and site speed. VoltTest is HTTP and HTTPS only — no WebSocket, gRPC, SQL or accessibility testing — so if you need protocol breadth or non-load site auditing, LoadForge covers more ground. Geographic reach is not one of those gaps: VoltTest generates load from 24 AWS regions against LoadForge's 19.
Should I use LoadForge or VoltTest for a Laravel application?+
Choose VoltTest if your team writes PHP daily and wants load tests in the same language and repository as the application, with Artisan commands, route discovery, automatic CSRF and cookie handling, and PHPUnit assertions for gating CI. Choose LoadForge if your team is comfortable with Python and Locust, needs test types beyond HTTP load such as GraphQL or SQL, or wants scheduled recurring runs with SLA alerting. Both handle multi-step scenarios, CSV-driven data, staged load profiles, P95/P99 reporting and multi-region load generation.
