6 Free Developer Tools I Built in One Day (No BS, Just Tools)

#tools #productivity #webdev #opensource

I was tired of slow, ad-filled online tools. So I built my own.

What I Built

6 completely free tools - no signup, no ads, no tracking:

  1. JSON Formatter - Format, validate and minify JSON with syntax highlighting
  2. UUID Generator - v4 and v7 UUIDs in bulk, one-click copy
  3. Base64 Encoder/Decoder - Full UTF-8 support
  4. Color Converter - HEX, RGB, HSL with visual picker
  5. Code Pastebin - Share code snippets instantly
  6. Character Counter - Real-time character and word counting

Why Free?

I also sell premium tools (Python scripts, ChatGPT prompts, Excel guides) but these 6 are completely free forever. No email required. No limits. Just open and use.
