About Loadster
Loadster is a cloud service for load testing and synthetic monitoring of websites and APIs. One set of test scripts serves both jobs, so teams can stress a site before launch and then keep watching it afterwards.
Products and services
- Script recording: records scripts visually through a free browser extension, with added JavaScript editing where needed.
- Multiple bot types: automates tests with Playwright, or with its own Browser Bots (real headless Chrome) and Protocol Bots (lightweight HTTP clients).
- Large-scale load testing: runs bots from dozens of AWS and GCP cloud regions to find a site's breaking point and scalability bottlenecks.
- Continuous monitoring: reuses the same scripts as monitors running from locations across five continents, checking key pages and user journeys around the clock.
Key facts
- Based in: United States
