Frontend developers

Quickly format payloads, inspect URLs, test colors, check contrast, preview Markdown, and generate assets.

  • Use JSON, URL, Base64, color, SVG, and image utilities from one place.
  • Validate API payloads while building UI integrations.
  • Keep small design and data tasks out of heavyweight desktop tools.

Backend and API developers

Test HTTP requests, generate IDs and tokens, inspect encodings, parse timestamps, and manage API-related data.

  • Use the API client, UUID generator, cron builder, JWT decoder, and hash tools.
  • Create mock data and compare payload changes.
  • Keep references like HTTP status codes and MIME types close to the workflow.

DevOps, students, and teams

Use MyDevTools for repeatable operational checks, secure workflow notes, and learning-friendly utilities.

  • Generate Docker Compose starters, secrets, and environment helpers.
  • Self-host for internal team workflows or classrooms.
  • Use one searchable toolkit instead of a long list of single-purpose websites.
