Developer Playground is a collection of 10+ powerful, privacy-first tools for modern web development for developers, designers and students. All tools run entirely in your browser - your code never leaves your device.
👋 Hey Product Hunt!
I'm excited to share Developer Playground - a passion project born from a simple frustration: why should developers pay for basic tools or sacrifice privacy by uploading code to random websites?
🎯 The Problem:
As a developer, I constantly needed to format code, test accessibility, minify JavaScript, or generate favicons. Most tools either required signup, had usage limits, or raised privacy concerns.
💡 The Solution:
Developer Playground bundles 10+ essential tools that run entirely in your browser. Your code never leaves your device, and everything is completely free.
🔥 What Makes It Special:
Accessibility Playground - My favorite feature! Live WCAG compliance checks with Monaco editor. Perfect for learning and testing accessible components.
Database Schema Designer - Visual drag-and-drop interface that exports to PostgreSQL, MySQL, or SQLite
All tools are privacy-first - No server uploads, no tracking, no data collection
No artificial limits - Format 10KB or 10MB files, we don't care!
🚀 Built With:
Next.js 15, Monaco Editor, Prettier, Terser, Tailwind CSS 4, and lots of ☕
