Code2Context — LLM-Ready Codebase Converter

Overview

Code2Context is a small, focused dev tool that converts a local codebase into a single structured context file optimized for LLMs that lack native folder access. It handles recursive directory scanning, smart filtering (node_modules, build artifacts, lock files, binaries), and generates an output format that maximizes signal-to-noise for the AI.

Built before agentic coding CLIs made folder access trivial — still useful for one-off analyses, code review prompts, and LLMs that only accept a single text input.

🎯 Features

• Local file processing — upload and process directories from your machine
• Intelligent parsing — recursive scan with exclusion patterns for boilerplate
• LLM-optimized output — single file, structured tree, de-duplicated content
• Rate limiting built-in — 20 scans/min, 10 generations/min, 60 general requests/min
• One-click Vercel deployment

🛠️ Tech Stack

• Next.js App Router, TypeScript
• Vitest for unit tests, Playwright for e2e
• Vercel for serverless deployment with built-in rate limits

💡 Why I Built This

The first time I wanted to ask an LLM to review an entire small codebase, I hit the wall that most of us did: the chat interface accepts text, not folders. Code2Context is the wizard (🧙‍♂️) that bridges the gap. Now superseded for me by Claude Code and Cursor, but still handy when you want a single text artifact for sharing or archiving.
