dev-sidecar for Windows

Overview of dev-sidecar

dev-sidecar is a free Windows utility that helps developers manage HTTPS traffic during development. It runs as a lightweight sidecar proxy on your machine and routes requests through optimized local acceleration channels, reducing the friction of testing secure endpoints and improving network response times.

How it operates

• Runs locally and intercepts HTTPS requests to forward them through faster domestic acceleration routes.
• Acts as a proxy that simplifies connection setup between your app and external services.
• Requires minimal configuration to begin routing and debugging traffic.

Benefits for development

• Speeds up API testing and reduces latency when calling remote services.
• Simplifies debugging by centralizing network traffic through a single local proxy.
• Lowers the complexity of certificate and HTTPS configuration during development.

Suggested substitute

If you’re looking for an alternative, consider 3uTools — a free option that some developers use for device management and network-related tasks. While it serves a different primary purpose, it can be useful in workflows that require quick device interactions and certain network utilities.

Getting started tips

• Install the Windows build and run it alongside your development environment.
• Point your application’s proxy settings to the local proxy address provided by dev-sidecar.
• Verify HTTPS traffic is being forwarded and use familiar debugging tools to inspect requests.
