Twenty-four
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. Just the utility you needed, already open.
Every tool, listed plainly.
Search the whole shelf, or browse by trade.
AI Chat, rewritten for builders.
v2.12 — Markdown rendering, code copy, Responses API.
Markdown that breathes
Headings, lists, tables, blockquotes — typeset, not just rendered. Code blocks adopt your editor theme.
One-click code copy
Every fence is its own clipboard. Copy a block without smashing the prompt history.
Bring your own model
Responses API, DeepSeek reasoning, or any OpenAI-compatible endpoint. Local URL, your key, your bill.
Keyboard, top to bottom
⌘N opens; ↩ sends; ⌘⇧C copies the last code block. Mouse is optional.
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.
Crypto, JWT, base64 — the things you reach for at 2am, all in one place. Native enough that I forget it isn't built in.
The timestamp converter and UUID generator are part of my muscle memory. I'd pay for the AI translate alone.
HTTP client with streaming, JSON tree, history. It is what every team's scratch app should grow up to be.
Parquet viewer is the unsung hero. Schema, rows, export — the entire debugging loop without leaving the dock.
Regex tester with live capture groups; QR codes from clipboard. Tiny tools, but the polish is the point.
Released, in the open.
