LoadNinja

Load and performance testing tool that records and replays tests in real browsers at scale

LoadNinja is a load and performance testing tool from SmartBear. It uses a recorder (InstaPlay) to capture web and API tests without coding, runs load using real browsers rather than emulators, and reports browser-based navigation timings, response times, and network data. Tests can be parameterized and automated through a public REST API and custom CI/CD plugins, and it integrates with Zephyr Squad (formerly Zephyr for Jira). Internal applications on a local network can be tested using a private proxy, dedicated IP, or IP whitelisting.
