Hello! I'd like to add DevToolBox to the Transformation section.

DevToolBox (https://usedevtools.com/) provides 75+ browser-based developer utilities with complete local processing and zero data transmitted to servers.

Features include:

  • Encoding/decoding (Base64, URL, HTML, JWT)
  • Data format conversion (JSON, CSV, XML, YAML, TOML)
  • CSS tools and color pickers
  • Hash generation (MD5, SHA, bcrypt, HMAC)
  • Network utilities, regex tester, QR codes, and more

All processing happens entirely in the browser. The project is open source and features a bilingual Japanese/English interface.

Thank you for maintaining this awesome list!

Switch to pull_request_target so the workflow has write permissions for
PRs from forks. Update actions-comment-pull-request to v3, drop the
unnecessary checkout step, and use the reliable PR author reference.
… args

- Switch links-pr.yml to pull_request_target so it can comment on fork PRs
- Update all actions to latest major versions (checkout v4, lychee-action
  v2, github-script v7, create-issue-from-file v6)
- Migrate deprecated lychee --base flag to --root-dir
- Add explicit least-privilege permissions
Align both with clear, consistent requirements: browser-based, direct
link, and 100% free.
… dead links

- Add .lycheeignore for sites that block crawlers or have flaky timeouts
- Remove comment-spam step from links-pr.yml (lychee v2 job summary suffices)
- Skip bot comments/reopen on PRs opened by the repo owner
- Remove dead links: Viewport Resizer, JSON-to-Chart
…alidator

Three browser-based developer tools from PureDevTools:
- CORS Header Generator: visual CORS header configuration, 100% client-side
- CSS Filter Generator: compose CSS filter effects with real-time preview
- YAML Validator: validate YAML syntax with line numbers, format, convert to JSON

All tools are free, require no signup, and process everything in the browser.
Added ApiNotes validator and diff tool

Hey Rih0z! Thanks for your submission! 🚀

To keep awesome-devtools instantly accessible for everyone, all tools must be:

  • Browser-based — no downloads or native app installs
  • Direct link — goes straight to the tool (not a multi-tool landing page)
  • 100% free — no signups, trials, paywalls, or usage limits

Please make sure your PR meets these criteria. It may take some time for your submission to be reviewed — you can occasionally comment with a "bump" to bring more attention to it.

Thanks for contributing! 🙌

Removed duplicate entry for DevToolBox from the README.
