Sauce Connect Proxy: Secure Tunneling Solution for Application Testing

Primary Purpose:
Sauce Connect Proxy is a secure tunneling solution designed to enable testing of applications behind firewalls or on local environments using Sauce Labs infrastructure. It allows developers and testers to run tests on non-publicly accessible applications, such as locally hosted web apps or staging environments protected by IP allowlists.

Key Features:

• Secure Tunneling via HTTP/2:
  Establishes encrypted tunnels using the HTTP/2 protocol, ensuring seamless integration with enterprise firewalls and proxies for enhanced security.

• Performance Enhancements:
  Delivers faster tunnel startups, quicker test execution, and reduced CPU and memory usage, making it ideal for high-concurrency environments.

• Observability:
  Provides real-time metrics through Prometheus-compatible endpoints and pre-built Grafana dashboards, enabling monitoring of tunnel usage, uptime, and system health.

• Easy Installation:
  Available in multiple formats including winget (Windows), Homebrew tap (macOS), deb/rpm packages (Linux), and binaries for various architectures, ensuring compatibility across systems.

• Advanced Proxy Capabilities:
  Supports Secure WebSocket with TLS resigning, SOCKS5 upstream proxies, and PAC file routing for flexible network configurations.

Audience & Benefit:
Ideal for developers and testers working with Sauce Labs, enabling secure testing of non-public applications without exposing them to the internet.
