52 developer tools, all running client-side in the browser
Overview
A comprehensive suite of 52 developer tools that run entirely in the browser. Every tool processes data client-side—no data ever leaves the user's machine. Features Monaco Editor for professional code editing, bidirectional code generators, and a custom AST-based type inference engine.
The project leverages Next.js 16 with React 19, Tailwind CSS v4, and a sophisticated type inference system that can merge multiple JSON samples to generate complete TypeScript interfaces. Each tool has custom SEO metadata, OpenGraph images, and contributes to an auto-generated sitemap.
Architecture
Type Inference Engine
Custom AST-based system that analyzes JSON samples and infers complete TypeScript interfaces. Merges multiple samples to handle unions, optional fields, and nested objects.
100% Client-Side
All 52 tools process data entirely in the browser. No server roundtrips, no data transmission. Built with privacy as a core feature.
Bidirectional Generators
JSON ↔ TypeScript, JSON ↔ Zod, JSON ↔ JSON Schema converters with round-trip support. Parse existing code and regenerate different formats.
Monaco Editor
Professional code editing with syntax highlighting, auto-complete, and error detection for all code-based tools.

Key Technical Challenges
Custom Type Inference Engine
Built an AST-based type inference system that analyzes JSON samples and generates complete TypeScript interfaces. The engine handles nested objects, arrays, union types, and optional fields by merging multiple samples to infer the complete type structure.
Bidirectional Code Generators
Implemented round-trip conversion between JSON, TypeScript, Zod schemas, and JSON Schema. Can parse existing code and regenerate different formats while preserving comments and structure.
Visual Code Builders
Created visual builders for CSS gradients, box shadows, and cron expressions. Users can configure values through UI controls and see live previews while generating clean code output.
Privacy-First Architecture
All 52 tools process data entirely in the browser with zero server roundtrips. Implemented client-side processing for complex operations like bcrypt hashing, JWT encoding, and file compression without compromising user data.
