BrowserStack Test Companion

Test Companion is BrowserStack's agentic AI for software testing, living inside the IDE instead of a separate dashboard — it writes and runs test scripts, debugs failures, and keeps tests updated as the app changes, across functional, visual, accessibility, and API testing. It plugs into Playwright, Selenium, Cypress, Appium, and WebdriverIO, and installs into VS Code, JetBrains, Cursor, and Antigravity. BrowserStack says teams using it since launch have been authoring and maintaining tests roughly four times faster than before.
