Version 2.16.0 — released August 2026 NEW · Two AI protocols

Twenty-five
developer tools,
one quiet macOS app.

The small, daily things — formatting, decoding, comparing, generating — gathered into a single native window. No tabs, no spinners, no telemetry. And now in Spotlight: press ⌘Space, type the conversion, read the result inline — it's on your clipboard before the app even opens.

Currently most-used: JSON.

§ 01 — The index

Every tool, listed plainly.
Search the whole shelf, or browse by trade.

§ 02 — Spotlight

Your tools, now in Spotlight.
v2.15 — 11 commands run inline, no app window needed.

DevUtilities Spotlight command — generating an MD5 hash inline with the result shown directly under the Spotlight bar.

⌘Space is the whole workflow

Convert a timestamp, hash a string, generate a UUID — type the command, fill parameters inline, read the result in place. The app never opens.

ii

Result on your clipboard

Every command copies its output automatically. Run it, ⌘V it, done — no selecting, no extra keystroke.

iii

Eleven commands, nine tools

Timestamp, number base, units, Base64, URL, JWT, hashes, UUIDs, random strings — the quick-hit conversions you reach for daily.

iv

Shortcuts & Siri for free

Built on App Intents, so every command is automatable in Shortcuts and callable through Siri — quick keys included on macOS 26.

What developers say
when the App Store stops listening.

The JSON diff has saved me from at least a dozen late-night API pages. It feels like the tool the Mac always wanted.
Sarah J. Senior Full-Stack Engineer
Crypto, JWT, base64 — the things you reach for at 2am, all in one place. Native enough that I forget it isn't built in.
Michael R. Security Engineer
The timestamp converter and UUID generator are part of my muscle memory. I'd pay for the AI translate alone.
Emily W. iOS Developer
HTTP client with streaming, JSON tree, history. It is what every team's scratch app should grow up to be.
David L. Backend Engineer
Parquet viewer is the unsung hero. Schema, rows, export — the entire debugging loop without leaving the dock.
Alex K. Data Engineer
Regex tester with live capture groups; QR codes from clipboard. Tiny tools, but the polish is the point.
Jessica M. Frontend Developer
