By simulating from a handful to hundreds of thousands of concurrent users, it reveals exactly how your systems behave under pressure—so you can fix bottlenecks before customers notice. What sets LoadView apart is that it runs tests in real browsers, not just simple HTTP requests. While many tools only measure raw server response times, LoadView reproduces the complete user experience—loading pages, executing JavaScript, rendering dynamic content, and interacting with your application exactly as a genuine visitor would. This produces performance data reflecting what users actually feel—accurate, actionable results. Building realistic test scenarios is fast and code-free thanks to the EveryStep Web Recorder. Simply click through your site or application—log in, search, add to cart, check out—and EveryStep captures every action into a reusable script you can replay across more than 40 desktop and mobile browser and device combinations, without writing a single line of code. For teams with existing assets, LoadView natively supports Postman Collections, JMeter scripts, and Selenium scripts, so you can reuse prior work and scale it into full load tests instantly. LoadView gives you precise control over how load is applied through flexible load curve options. The Load Step Curve ramps users up and down in defined increments to observe behavior at each level. The Goal-Based Curve targets a specific number of concurrent sessions—ideal for validating against a known traffic goal. The Dynamic Adjustable Curve lets you change load on the fly during a live test. With unlimited parallel testing, you can model everything from a gradual build to a sudden spike from a launch, flash sale, or viral moment. Running on a global cloud network, LoadView generates load from numerous geographic locations worldwide via leading providers like AWS and Azure, measuring performance the way real users in each region experience it. The infrastructure is fully managed—no servers to provision, no load generators to configure, and no hardware to maintain. For applications that aren't publicly accessible, the on-premise agent and behind-the-firewall testing options let you safely load test internal sites and pre-production environments without exposing them to the open internet. After each test, LoadView delivers detailed, easy-to-read performance reports with metrics like average response time, sessions per second, error rates, and waterfall charts that break down every element on a page. Performance data is correlated against your user load, so you can pinpoint the exact moment and component where problems begin—key insight for capacity planning, SLA validation, and continuous improvement. LoadView also integrates with CI/CD pipelines, letting you automate performance testing as part of your release process. LoadView serves organizations of every size, from startups to large enterprises across ecommerce, financial services, healthcare, government, education, and media. Common use cases include preparing for high-traffic events, validating launches, stress-testing APIs and chat apps, and ensuring platforms like Salesforce hold up under load. Pricing is flexible and transparent. A zero-commitment, pay-as-you-go on-demand plan is perfect for occasional tests, while monthly and annual subscriptions suit teams with ongoing needs and include rollover of unused resources. Custom enterprise plans add dedicated performance engineering, SSO, and advanced account management. Every new account starts with free tests and no contract.
