Testable.io

Testable is an innovative distributed load testing and synthetic monitoring platform. Define a test with a variety of open-source tools and let Testable handle the scale, reporting, and analytics. Supports JMeter, Gatling, Locust, Node.js (including HTTP, websockets, Socket.io, and Engine.io), Webdriver.io, Selenium Java, Serenity BDD, PhantomJS, SlimerJS, record-and-replay, and HAR files. Load can be generated on our globally distributed AWS infrastructure, on premises using Docker, or by Testable automatically spinning up isolated on demand EC2 instances for each test using our AWS account or yours. Simulate as many virtual users as you can from the test runners without having to pay more. 1 m4.large can often generate 1000+ virtual users depending on the tool. Real-time results include percentiles, success analytics, and trend analysis for every single metric. Want to know how many concurrent users your environment can handle? Define your performance requirements and let Testable automatically figure it out. Track how that number changes across test runs like any other metric. Define your own KPIs and get alerted when a test fails to meet them. Results can be shared and customized to provide different views for different stakeholders. We also integrate with leading monitoring tools like NewRelic and CI solutions to seamlessly integrate load testing and monitoring into your software development lifecycle.

WAPT Pro

WAPT Pro is a load and performance testing tool that works for any web site from a simple web service to a customized ERP or CRM solution. Mobile web applications, corporate portals and intranet sites implemented with any technologies can be easily tested with WAPT Pro. The test is created in a matter of minutes by recording it in a browser. A few clicks are required to make thousands virtual users concurrently execute duplicated sessions against your site. A convenient user interface lets you design data-driven tests with help of variables and session-specific values extracted from the server responses. This is done explicitly in the properties of each HTTP request. No scripting is required for the test implementation. Descriptive graphs and reports will let you analyze the performance parameters of the system components under various load conditions. You can isolate and fix any bottlenecks and optimize your software and hardware configuration. WAPT Pro is quite efficient and scalable. While the default configuration is sufficient to run up to 4k concurrent virtual users, you can easily extend it by adding multiple servers connected to a single workplace component. This way you can emulate up to 1M users. All components can be used in any virtual or cloud environment. A special edition is provided through the Amazon EC2, where you can use it at hourly price that depends on the test load volume.

Evaluat

Evaluat is a real-browser performance testing platform that runs each virtual user in an isolated browser instance, capturing Core Web Vitals and Navigation Timing metrics under load, with full session video, network logs, and console logs for every user. Most load testing tools generate traffic at the protocol level. They fire raw HTTP requests and measure server response times, but they never render the page. That tells you whether your servers stayed up. It does not tell you whether customers could actually use the site. Evaluat renders every page in a real browser, so the results reflect what a person experiences as concurrency rises. Because each virtual user is a real browser, Evaluat captures Core Web Vitals (LCP, INP and CLS) while the site is under load, rather than in a single-user lab check. Navigation Timing, FCP, TTFB and an Apdex score are recorded alongside them. You can watch front-end performance degrade as traffic climbs, which is exactly where protocol-level tools go quiet. Every virtual user is recorded. When a run surfaces a slowdown or an error, you open that session, watch the video, and inspect the network requests and console output behind it. There is no guesswork about which user hit the problem or what the browser was doing at the time. Scenarios are built step by step in a no-script editor, so the people who understand the customer journey can define the test without writing code. Record a journey once and reuse it across releases and environments. Runs can be scheduled, which turns a rehearsal before a campaign into a routine check rather than a one-off project. Every plan produces the same diagnostic report. Executive Summaries, a plain-language verdict for stakeholders who will not read percentiles, are generated on demand on higher plans. Evaluat is built for e-commerce, retail and ticketing teams whose revenue concentrates into a few hours: Black Friday, flash sales, product drops, ticket on-sales and campaign launches. Agencies and hosting partners use it to prove a build or an infrastructure change holds up before handing it to a client. Plans are sized in virtual user-minutes, meaning one simulated visitor in a real browser for one minute. Test data resides in the region the test ran in.
