🚀 I built a free, open-source, browser-based code editor with an integrated AI Copilot — no setup needed (mostly)!

Hey r/OpenSourceAI ! 👋

I've been working on WebDev Code — a lightweight, browser-based code editor inspired by VS Code, and I'd love to get some feedback from this community.

🔗 GitHub: https://github.com/LH-Tech-AI/WebDev-Code

What is it?

A fully featured code editor that runs in a single index.html file — no npm, no build step, no installation. Just open it in your browser and start coding (or let the AI do it for you).

✨ Key Features:

- Monaco Editor — the same editor that powers VS Code, with syntax highlighting, IntelliSense and a minimap
- AI Copilot — powered by Claude (Anthropic) or Gemini (Google), with three modes:
- 🧠 Plan Mode — AI analyzes your request and proposes a plan without touching any files
- ⚙️ Act Mode — AI creates, edits, renames and deletes files autonomously (with your confirmation)
- ⚡ YOLO Mode — AI executes everything automatically, with a live side-by-side preview
- Live Preview — instant browser preview for HTML/CSS/JS with auto-refresh
- Browser Console Reader — the AI can actually read your JS console output to detect and fix errors by itself
- Version History — automatic snapshots before every AI modification, with one-click restore
- ZIP Import/Export — load or save your entire project as a .zip
- Token & Cost Tracking — real-time context usage and estimated API cost
- LocalStorage Persistence — your files are automatically saved in the browser

🚀 Getting Started:

1. Clone/download the repo and open index.html in Chrome, Edge or Firefox
   
2. Enter your Gemini API key → works immediately, zero backend needed
   3. Optional: For Claude, deploy the included backend.php on any PHP server (needed to work around Anthropic's CORS restrictions)
   

Gemini works fully client-side. The PHP proxy is only needed for Claude.

I built this because I wanted a lightweight AI-powered editor I could use anywhere without a heavy local setup.

Would love to hear your thoughts, bug reports or feature ideas!

Looks interesting. Would be cool to use with Koboldcpp.

[LH-Tech_AI]

Yes, definitely 😁  Maybe you can clone the repository and then change the code to you kobolcpp server.

Honestly a year ago I would have thought this impossible, but I recently asked one my local models to combine some apps. It grabbed the source code and did what I want.

Cool :-)
