Sauce Connect 5.2.0: Why You Should Migrate

Sauce Connect 5.0 offers significant enhancements in performance, security, and integration for accessing local environments behind a corporate firewall while running tests on Sauce Labs. The new version boasts up to five times faster test speeds and 50 times less memory usage than its predecessor, allowing for lower latency and more efficient test executions. Transitioning from the proprietary KGP protocol to the widely adopted HTTP/2 protocol with SOCKS5 and websocket support simplifies security approvals and strengthens connections. The streamlined onboarding process facilitates easier integration into CI/CD environments, while a new Prometheus metrics dashboard provides in-depth performance insights. In Sauce Connect v5.2.0, several enhancements have been introduced to improve performance, security, and usability. These include reverting to resigning domains by default for better latency and request handling, increased tunnel capacity with support for up to 4,096 concurrent requests, SSLKEYLOGFILE support for inspecting encrypted traffic, automatic client metrics collection, and enhanced log visibility for easier debugging and monitoring. Benchmark results show that Sauce Connect v5.2.0 delivers tangible performance improvements, with up to a 32.5% increase in network throughput and an impressive 850% increase in request handling compared to earlier versions. These enhancements contribute to faster, more secure, and more reliable testing, making it the ideal time to upgrade from v4 to the latest version.
