Cloud browsers let developers run, test, and debug code in isolated browser environments hosted remotely. Instead of configuring multiple local setups, teams can spin up clean browser instances on demand, mirroring real-world conditions across operating systems and device types. Many platforms offer features like network throttling, geolocation spoofing, and automated screenshot capture to streamline QA and cross-browser compatibility checks. Secure sandboxes protect source code and data, while integrations with CI/CD pipelines support automated testing at scale. Session recording, collaborative debugging, and instant environment resets further reduce friction in the development process. By shifting browser testing to the cloud, these tools help teams ship more reliable web applications without the overhead of local maintenance.
