The HeadSpin platform is an industry first, providing a powerful, easy-to-use solution that enables development, QA, product, and operations teams to accelerate release cycles, build for complex real-world user environments, and know whenever any component of the system degrades or breaksโwhether at the code, device, or network layerโanywhere in the world.
Since inception, the platformโs extensive on-prem and cloud-hosted global device infrastructure has been expanded with machine learning-driven performance and quality of experience analytics to proactively test and monitor mobile, web, audio and video applications in real-time.
Loadster is a cloud-based load testing and synthetic monitoring platform for engineers who want to know how their applications behave under real traffic.
Tests run with three types of bots: Protocol Bots for HTTP testing, headless Browser Bots that render full pages and execute JavaScript in real Chrome browsers, and Playwright bots for when you want to use Playwright JS directly.
Loadster scripts can be recorded from Chrome or Firefox with the Loadster Recorder extension, edited in a built-in editor with variables, datasets, and shared includes, and then replayed from multiple cloud regions.
Each test run returns detailed page timings (TTFB, FCP, LCP, CLS, etc) alongside resource waterfalls, screenshots, and full traces you can step through in a self-hosted trace viewer. Tests scale from a handful of virtual users (bots) to hundreds of thousands across distributed cloud engines without you provisioning anything.
The same scripts can be set up as monitors that run on a schedule from chosen regions. Notification policies route incidents to email, SMS, voice, or integrations like Slack and PagerDuty. Projects, roles, and shared test history keep teams aligned on what passed, what failed, and what changed.
Pricing is usage-based via Loadster Fuel, with 50 free units on sign-up and no credit card to start.

Headspin has been an essential part of our testing process from the beginning. We've used it to test everything from mobile sites to native applications and we've found it to be invaluable for both developers and testers. We can run tests on any device from any location in the world, and the bug reporting feature makes it easy to track down and fix errors.
We use Headspin automation to run our functionality tests across multiple browsers and operating systems. We can identify UI misalignment specific to browsers or failures due to incompatibility with a particular browser. The good part is you can automate screenshots and get insights into where the UI of your website is going off. Then we can use the live feature to identify and debug the compatibility issue. We strongly believe customer experience is the key, and that could impede your product growth. With Headspin, we could see improvements in identifying errors before our customers do!
We have been using HeadSpin for a while now, and we're pleased with their services.
Their customer support is available 24x7 and they have helped us many times with any issues or questions we had. They are always up to date with the latest version of browsers, which is something we highly value.
They have a wide selection of browsers and operating systems, which makes it easy for us to identify the issue on our website and solve it in no time.
