Hey DEV community! 👋

I wanted to share a personal experiment I've been working on recently. The catch? I have absolutely zero professional coding background. I just wanted to see how far a complete beginner could push current AI tools to build a real, functional desktop application from scratch.

After weeks of prompting, configuring, and troubleshooting, here is the result: Nexus Browser — a secure, lightweight web browser built in Rust, featuring a Neon Cyberpunk GUI, a built-in ad blocker, and a multi-threaded download engine.

🛠️ My AI Development Crew
Since I couldn't write the code myself, I had to manage and coordinate three different AI assistants like a project manager:

Google Gemini 🤖 – Acted as my software architect and system administrator. It helped me map out the project structure and, most importantly, guided me through complex environment setup errors (like handling tricky NixOS and Google IDX configuration issues when compiling libraries like webkit2gtk).

Qwen Studio 💻 – Served as my primary backend developer. It generated, optimized, and compressed the Rust source code, and also helped craft the Cyberpunk-themed HTML/JS interface.

Replit AI ☁️ – Provided a quick cloud environment to test and run my early prototypes before moving things locally.

⚠️ Current Status: Lots of Bugs & The 4GB RAM Struggle!
To be completely honest, the browser currently has a lot of bugs and internal issues. Since it was built entirely through AI prompts, some parts of the code are not fully optimized, and there are occasional crashes and weird UI rendering glitches. I am actively working with the AIs to debug, refactor the code, and fix these issues one by one.

But here is the funniest part: I can't even properly test my own browser right now because my laptop only has 4GB of DDR3 RAM! 💀

Every time I try to run a heavy compile or open too many preview windows, my poor laptop gasps for air and threatens to explode. So if you clone the repo and find a major bug, just know that my 4GB RAM setup was doing its absolute best to survive the compilation process!

💡 Key Lessons I Learned Along the Way
Modular Prompting is Everything: Asking an AI to "build a whole web browser" right away is a recipe for broken code. I had to break the project down into tiny, isolated pieces: first building a basic window, then adding the Cyberpunk UI styling, then injecting the ad blocker logic, and finally implementing the download manager.

Environment Setup is the Real Boss: Writing code with AI is relatively fast, but setting up the correct compiler flags, managing dependencies, and making sure Rust plays nice with Linux graphics libraries took up a lot of time. Having Gemini double-check my build logs was a lifesaver.

🚀 Check it out!
I'm honestly amazed at what's possible today. A few years ago, building a custom Rust browser as a beginner would have felt impossible. Now, with the right AI collaboration, anyone can bring their ideas to life.

If you are curious about the project, want to help me debug, or have some solid advice on how a beginner can optimize the Rust code further, please check out the repository!
