Dublin – October 14, 2026 -- BrowserStack has made BrowserStack Load Testing generally available, letting teams run up to 1 million API virtual users and 1,000 browser virtual users per test to check web app performance before holiday and festive sales.
The product runs real browsers and API traffic in a single test. BrowserStack argues that server-only load tests no longer show the full picture, because modern web apps build much of each page inside the visitor's browser. A site can pass a server-side test while customers wait on a checkout page that will not load.
