Claude Code Open – Open-source AI Coding Platform with Web IDE, Multi-Agent System, and 37+ Tools

#ai #opensource #webdev #typescript

What I Built

I reverse-engineered Anthropic's Claude Code CLI (heavily obfuscated) to understand how it works, then built an open-source AI coding platform that goes beyond the original.

GitHub: kill136/claude-code-open
Live Demo: voicegpt.site:3456

Key Features

1. Web IDE — Not Just a Chat Window

A browser-based IDE built with React + Express + WebSocket:

Monaco Editor: Multi-tab, syntax highlighting, VS Code-like editing
File Tree: VS Code-style with context menus and drag-and-drop
AI-Enhanced Editing: Hover tips, inline code review, auto test generation
Terminal Panel: In-browser terminal
Git Panel: Status, commits, branch management
File Snapshots: Checkpoint & Rewind

2. Multi-Agent Collaboration (Blueprint System)

When a task is too complex for a single AI:

Smart Planner analyzes requirements and breaks them into subtasks
Lead Agent orchestrates and dispatches to multiple Workers
Autonomous Workers execute in parallel with full tool access
Swarm Console visualizes all agent states in real-time

3. 37+ Built-in Tools

Category	Tools
File Ops	Read, Write, Edit, MultiEdit
Search	Glob, Grep (ripgrep-based)
Execution	Bash, Background tasks
Browser	Playwright automation
Database	PostgreSQL, MySQL, SQLite, Redis, MongoDB
Debug	DAP Debugger
Code Intel	LSP, Tree-sitter parsing
Task Mgmt	TodoWrite, ScheduleTask
AI Collab	Task (sub-agents), Blueprint, Agent Teams
Memory	MemorySearch, Notebook

4. Scheduled Task Daemon

"Every day at 9am, review yesterday's git commits and notify me on Feishu"

Natural language time configuration
File change watching
Desktop + Feishu notifications
SQLite persistence

5. Self-Evolution

The AI can modify its own source code: edit TypeScript files → tsc compilation check → hot-reload. With dry-run preview and audit logs for safety.
