Questions and Answers

As answered by people managing Tests.ws and Proxyman.io.

What makes your product unique?

Tests.ws's answer

Websocket Proxy provides browser-native tools specifically tailored for modern WebSocket workflows. Unlike traditional debugging tools, it integrates directly into the browser, offering real-time insights and control over WebSocket traffic with zero setup. It's lightweight, developer-focused, and designed to feel like a natural extension of your dev tools.

Why should a person choose your product over its competitors?

Tests.ws's answer

Because WebSockets Proxy is purpose-built for WebSocket debugging. While most dev tools treat WebSockets as a side feature, we put it front and center. With a clean UI, message editing/resending via JavaScript, and upcoming features like a built-in client, it's the most focused and intuitive tool for real-time app developers.

How would you describe your primary audience?

Tests.ws's answer

Developers, QA engineers, and tech teams who work with real-time web apps using WebSocket connections. Especially useful for those building chat apps, live dashboards, games, or collaborative tools.

What's the story behind your product?

Tests.ws's answer

Websocket Proxy was born out of frustration with clunky, generic network tools that barely support WebSockets. Honestly, I was just too lazy to set up Burp Suite for quick checks. I needed something simple, fast, and browser-native, so I built it. What started as a side project to speed up internal debugging turned into a tool I realized others needed too.

Which are the primary technologies used for building your product?

Tests.ws's answer

JavaScript / TypeScript, WebExtension APIs, Chrome DevTools Protocol, Vite for bundling, TailwindCSS (for UI), WebSocket protocol (obviously 🙂)

Who are some of the biggest customers of your product?

Tests.ws's answer

While we're still early in our journey, Websocket Proxy already has 77 users in just the first couple of months. Many of them are developers from early-stage startups, QA engineers, and real-time app builders. One of them even reached out with a feature request - which is now in development. We're building based on real feedback from real users.

Top 10 HTTP Client and Web Debugging Proxy Tools (2023)
Proxyman just like Paw is a native macOS web debugging proxy application. This tool stands as an intermediary or a man-in-the-middle server. With its built-in macOS setup, you can capture, inspect and get around HTTP(s) traffic, request, and responses easily. What set Proxyman aside from Paw is the fact that it is more advance in functionalities.

Comparing Charles Proxy, Fiddler, Wireshark, and Requestly
On the pricing front, Requestly strikes a balance between affordability and functionality. It is an open-source tool, offering freemium to individual developers and affordable pricing plans for team collaboration. We have also clearly differentiated how Requestly differs from Wireshark and other web debugging tools like Proxyman, Modheader, and HTTP ToolKit separately.
