🚀 Built a Modern, Programmable Proxy to Replace Charles/Fiddler – Meet Lynx Proxy (Open Source)

suxin2017 — Thu, 05 Jun 2025 12:42:23 +0000

Hey folks,

I’m a full-stack dev who frequently switches between backend APIs and frontend UIs. Frustrated with the limitations of traditional proxies like Charles and Fiddler, I built something to fill the gaps — Lynx Proxy.

TL;DR

⚡ Modern HTTP/HTTPS/WebSocket proxy with real-time inspection
🧠 Programmable rule engine (AND/OR/NOT logic, match on headers, URL, body)
🖥️ Clean, web-based UI for live traffic monitoring and request filtering
🔄 Support for rewriting, redirecting, delaying, or blocking requests
🧰 Great for frontend/backend debugging, traffic routing, edge case testing
🔗 GitHub Repo

Why I Built It

Charles and Fiddler are solid tools, but I found them lacking for modern, automation-heavy workflows:

The UI feels dated
Rules are limited or hard to maintain
Hard to build dynamic, conditional behaviors

Lynx Proxy aims to be a developer-first tool that’s programmable, extendable, and intuitive to use.

Key Features

🧠 Flexible Rule Engine

Match requests using headers, methods, URL patterns, or even body content. Compose rules with AND/OR/NOT logic to do things like:

Block or delay specific requests
Add/remove/modify headers
Redirect or rewrite paths based on conditions

🖥️ Real-Time Web Dashboard

View live traffic in a fast, responsive UI. Automatically scrolls and updates as requests come in. Great for debugging or monitoring in high-throughput apps.

🔄 No-Restart Request Rewriting

Update rules on the fly without restarting. Useful for testing different flows or redirecting traffic between staging/prod/dev.

Use Cases

Debugging frontend/backend integration issues
Simulating network delays or API failures
Redirecting or modifying traffic in development environments
Selective blocking of 3rd-party scripts or endpoints
Observing and inspecting encrypted HTTPS / WebSocket traffic

What Makes It Different?

Feature	Lynx Proxy	Charles/Fiddler
Modern UI	✅	❌
Logical Rule Combinations	✅ (AND/OR/NOT)	⚠️ Limited
Live Rule Editing	✅ No restart	⚠️ Sometimes required
Open Source	✅	❌

If you’ve ever wished your proxy could do more — whether to debug, redirect, or simulate weird edge cases — give Lynx Proxy a try.

Would love to hear:

What would you use a programmable proxy for?
What’s missing from the tools you use today?

The project is under active development, so if you have suggestions, feedback, or feature requests — feel free to open an issue!

Thanks for checking it out!

Rust High-Performance Proxy: How lynx-server Reached 100 GitHub Stars

suxin2017 — Fri, 30 May 2025 03:22:03 +0000

Hi everyone! I’m suxin2017. In this post, I’ll share the journey of my open source project lynx-server reaching 100 GitHub stars, as well as the product design, community operation, and promotion strategies that made it possible.

Project Overview

Lynx Proxy is a high-performance and flexible proxy service written in Rust, specializing in efficient handling of HTTP/HTTPS and WebSocket traffic. The project leverages Rust's strengths in performance and safety, and integrates popular Rust networking libraries like hyper, axum, and tower. It also offers a modern web management UI and comprehensive visualization features.

Why Did It Get 100 Stars? My Practical Experience

1. Product Strength: Performance & Usability

🚀 High Performance: Powered by Rust, lynx-server efficiently sustains high-concurrency proxy traffic with low resource usage.
🌐 Multi-Protocol Support: Native support for HTTP, HTTPS, and WebSocket to meet most developers’ proxy needs.
💻 Modern Web UI: Clean, intuitive interface with dark mode, request list and tree views for easy traffic analysis.

2. Documentation & Onboarding Experience

Good documentation is key to earning stars.

Clear README: The homepage describes features, installation, and quick start instructions.
One-click Installer:

  curl --proto '=https' --tlsv1.2 -LsSf https://github.com/suxin2017/lynx-server/releases/latest/download/lynx-cli-installer.sh | sh

Quick Start:

  lynx-cli

Start the service with a single command, lowering the entry barrier for new users.

3. Open Source Community

Contribution Guide: Encourages community contributions and documents the development/build process.
Responsive Issue & PR Handling: Every feedback is taken seriously, increasing engagement.
Active Development: Regular updates and a public roadmap keep users excited about the project.

4. Visualization & Interaction Details

List View: Makes development and debugging easier.
Tree View: Clearly shows traffic data structure.

Community Promotion: Let More People Discover Your Project

If you want more stars, community promotion is essential. Here are some of my strategies for promoting lynx-server:

Technical Content Creation: Write use cases, architecture deep-dives, and tutorials on dev.to, Zhihu, Juejin, and other platforms so developers from various backgrounds can discover and understand your project.
Engage in Technical Forums: Actively answer questions in Rust, networking, and proxy-related discussions, and naturally recommend lynx-server.
Social Media Promotion: Share project updates, releases, and highlights on Twitter, WeChat, and other social platforms to attract followers.
Collaborate with Other Projects: Reach out to related project maintainers to explore integrations and cross-promotion.
Community Events & Live Streams: Join online tech talks and livestreams to explain your project’s concepts and applications, increasing interactivity.

Tip: Promotion is a long-term effort. Focus on valuable content and influence—avoid spamming or intrusive advertising.

How You Can Do the Same

Clear Positioning: Make it obvious what problem you solve and who your project is for.
Lower the Barrier to Entry: One-click install, single-command start.
Polish Docs and UI: Make it not only easy to use, but also visually appealing.
Consistent Maintenance & Responsiveness: An active community attracts more stars.
Proactive Sharing & Promotion: Create content to draw in like-minded developers and broaden your project’s reach.

Conclusion

lynx-server’s journey from 1 to 100 stars was built step by step. I’ll continue to improve it, and I welcome everyone to contribute and make this Rust proxy even better!

I want to develop a one-click installation environment tool, do you really need it?

suxin2017 — Sat, 11 Nov 2023 13:38:00 +0000

Guys, I'm trying to develop a piece of software for installing development environments in the context of front-end development onboarding that requires installing zsh nodejs yarn/pnpm git vscode vscode extends webstrom docker ... Software.
This would too waste me 2-3 hours, I want to make this thing 30 minutes and increase the Swiss Army knife speed of a new computer becoming a developer.
For an enterprise user to be able to better unify the environment for development engineers quickly, improving onboarding satisfaction and efficiency.
But I'm not sure I'm developing it for anyone to want to use it?
Can you all give me some advice?
