Developer tools format JSON, beautify HTML, minify CSS, encode Base64, and build accessible color palettes. They are ideal when you are debugging an API response, cleaning a snippet for documentation, or exploring UI colors.
Everything runs client-side where possible, which keeps staging credentials and proprietary payloads off upload servers.
What you can do here
- JSON validate, beautify, and minify
- Sandboxed HTML live editor
- Regex tester with safe limits
- URL and Base64 encode/decode
Frequently Asked Questions
Can I trust formatted JSON in production?
Always re-validate before deploy. Formatting fixes whitespace; it does not change business logic but invalid JSON will still fail parsing.
