Developer Tools Platform

One all-in-one developer toolkit for everyday engineering work

MyDevTools brings the utilities developers reach for every day into one desktop workspace that runs offline: format data, test APIs, generate tokens, inspect encodings, manage secure notes, and stay in flow — with everything processed locally.

Built for search-worthy developer workflows

The platform is organized around real engineering jobs instead of disconnected one-off utilities.

  • Formatters and validators for JSON, SQL, GraphQL, Markdown, CSV, and more.
  • Network and API utilities including an API client, HTTP status reference, MIME lookup, and IP subnet calculator.
  • Generators for UUIDs, API keys, QR codes, mock data, cron expressions, and Docker Compose files.

Why use a unified toolkit

A single toolkit reduces the switching cost of jumping between browser tabs, npm packages, desktop apps, and random pastebin-style websites.

  • Use related tools from one dashboard and command palette.
  • Keep every utility available offline on your machine — no network required.
  • Sync your work across devices with an account when you want continuity.

Designed for public discovery

Public tool landing pages explain what each utility does before sending users into the app experience.

  • Canonical public pages live under /tools for indexing and sharing.
  • Auth-gated app pages stay out of the sitemap to preserve crawl budget.
  • Structured data and llms.txt help search engines and AI assistants understand the toolkit.
