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, query databases, manage secrets and 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.

  • A JSON formatter and visualizer for everyday payloads.
  • An API client for REST, GraphQL, WebSocket and gRPC, with a mock server and collection runner.
  • Database clients for PostgreSQL, MySQL, MongoDB, Redis, Firestore and Elasticsearch, plus an S3 drive.

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.
  • Organize work into per-project workspaces, all stored locally on your device.

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.
