IT-Tools

A collection of handy developer utilities — a static single-page app with no backend, no account, and no data of its own: everything runs client-side in the browser, so there's nothing to configure or back up.

Getting Started​

Enable it, then bring the stack up from the repo root:

EXIST_IS_SERVICES_IT_TOOLS=true    # in .env.shared
./existential.sh && docker compose up -d

Reach it at https://it-tools.<domain> (Caddy + piHole required — see Hostnames that just work); container-to-container, it's http://it-tools:80.

Examples​

  • Random port generator
  • Text diff / JSON diff
  • JSON prettify and format
  • JSON to CSV
  • Base64 encoder/decoder
  • Case converter (lowercase, UPPERCASE, snake_case)
  • JWT parser
  • Regex tester and cheatsheet
  • HTTP status codes reference
  • ASCII art generator
