Features built for fast, private developer workflows

MyDevTools combines small daily utilities with a dashboard, search, and privacy controls in one offline desktop app — so developers stop juggling a dozen scattered websites and single-purpose apps.

Unified dashboard

Launch formatters, API tools, database helpers, generators, and productivity utilities from one place.

  • Search tools quickly with a command palette.
  • Group everyday utilities into one dashboard instead of scattered bookmarks.
  • Use public tool pages for discovery, then open the full app when ready.

Per-project workspaces

Keep each project in its own workspace — separate tools, notes, snippets, and vaults — and switch between them in a click. Everything stays local on your device.

  • Bookmarks, notes, snippets, and connections are scoped per workspace.
  • Switch between personal and project context instantly.
  • Shared team workspaces and collaboration are on the roadmap.

Offline, local-first utilities

Most tools run locally on your machine and work fully offline, which keeps common formatting and generation work instant.

  • Every utility ships in one desktop app — no chasing a dozen websites.
  • Works offline on a plane, behind a locked-down network, or air-gapped.
  • Local-first processing for formatter, parser, and generator workflows.

Private by default

Local-first tools process your data on your machine, and sensitive records live in a local encrypted vault.

  • Formatters, parsers, and generators run on-device with no server round-trip.
  • Secrets and credentials are AES-256 encrypted in a local vault.
  • Tools that reach a network only contact the destinations you choose.
