Digs through your clipboard.
Decodes everything.

Rakkun is a native macOS clipboard manager that understands what you copied. Hit V — JSON is already pretty-printed, the JWT is already decoded, the timestamp is already a date. Before you even ask.

Detection

It knows what you copied.

Every item in your history is detected, parsed, and given the actions it deserves — automatically, on-device, in native Swift.

JSON

Pretty-printed and syntax-highlighted the moment you copy it. Paste formatted, copy minified, or pull the value at a path.

{"user":{"id":48213,"plan":"pro"}}

JWT

Header and payload decoded, expiry tracked live. Copy the payload as JSON — or just the sub, since that's what you wanted anyway.

Colors

A hex code becomes a swatch with its RGB, HSL, SwiftUI Color and UIColor equivalents. Copy whichever one the file in front of you needs — hex included, so a clip that arrived as rgb() still hands you #A78BFA.

SVG

Every other tool shows you the wall of markup. Rakkun draws the icon — on a checkerboard, so white artwork isn't invisible — then hands you Copy as PNG at the size the document declares, at 1× and 2×, with the exact pixel dimensions in the menu item. Because Slack won't take an SVG. There's a data URI for CSS too.

Timestamps

Unix seconds or milliseconds, translated to local time, UTC, relative, and ISO 8601 — no more pasting ten digits into a converter tab. The copies run both ways: an ISO date hands you the epoch back, in seconds or milliseconds.

URLs

Tracking parameters stripped automatically. Paste the clean URL; the original stays one keystroke away if you really want the utm_source.

?utm_source=slack&fbclid=… removed

curl commands

Formatted multiline for reading, converted to URLSession or fetch() for shipping. Your API docs just became paste-able code.

curl -X POST → URLSession / fetch()

SQL

A query from a log or an ORM dump comes out formatted and highlighted. Paste it readable, copy it as one line, or as an escaped string for source code.

Stack traces

Your frames highlighted, framework noise collapsed. Paste just your own frames into the bug report — the 200-frame trace becomes the 6 lines that matter.

42 frames → paste your frames only

Certificates

A PEM becomes subject, issuer, SANs and validity at a glance — expiry tracked like a JWT. Copy the SHA-256 fingerprint, or the whole cert as one line for an env var.

*.example.com · expires in 41 days

Base64

Decoded on sight — and if what's inside is JSON, Rakkun keeps decoding. Paste the decoded text directly; the original stays one keystroke away.

eyJ1c2Vy… → decodes to: JSON

Cron expressions

The five fields become a sentence and the next few run times — in your time zone, so 0 4 * * MON stops being a small puzzle.

0 4 * * MON → every Monday at 04:00

API keys & tokens

Tokens from dozens of providers are recognized and masked, so a secret never sits in plain sight. Paste or copy still uses the real value; pin one and it moves to the macOS Keychain — never the history file.

UUIDs & ULIDs

Canonical, uppercase, lowercase, or hyphenless — whichever your database wants, one keystroke away. ULIDs decoded too.

550E8400-E29B-… → lower / no-hyphens

Screenshots & QR codes

Copy an image and Rakkun reads it on-device: a screenshot becomes selectable text, and a QR code becomes the link it encodes — ready to open. The image is never stored and never leaves your Mac.

QR screenshot → https://… ready to open

Everything else

Plain text gets the full treatment: fuzzy search with /kind, /qr and @source filters, transforms (trim, change case, escape or unescape JSON), pinning, paste without formatting, and drag any item out as a file — or ⌘S to save it.

/json @terminal → filtered history

Honest about the edges. Detection only fires when the clip is the whole thing — an <svg> pasted inside a React component stays plain text, so never has to guess which half you meant. And the picture comes from macOS’s own renderer, not a browser engine: <style> rules and filters do apply, <foreignObject> HTML doesn’t draw, and a reference Rakkun can’t load — it has no network access at all — shows as a red box instead of quietly vanishing.

The race

Twenty-four seconds. Or two.

You copied a JWT and you need the sub claim. Here is that moment, with and without Rakkun — and with a decoder website, your token takes a trip to someone else’s server on the way.

Privacy

Your clipboard is nobody’s business.

A clipboard manager sees everything you copy. That’s exactly why Rakkun is built so it can’t betray you.

Passwords are never recorded

Anything copied from a password manager (concealed pasteboard types) is skipped entirely — and you can exclude any app the same way. Not masked, not encrypted — never recorded at all.

Never leaves your Mac

History lives on your device and nowhere else. No sync service, no server, no account. Nothing you copy ever touches a network.

No clipboard analytics

Zero telemetry on clipboard contents. Rakkun is 100% native Swift 6 and SwiftUI, sandboxed, with the hardened runtime — the Mac App Store way.

Strip secrets before they leave

Pasting a config or log somewhere public? Rakkun flags embedded API keys, tokens and passwords — Strip & Paste redacts them in one action.

Keyboard-first

Your hands never leave the keys.

Summon, search, act, paste — the whole loop is keystrokes. The mouse is optional equipment.

  • VOpen the panel from anywhere
  • Move through your history
  • Paste into the app you came from
  • Paste it another way — original, decoded, unformatted
  • CCopy as… — minified, decoded, converted
  • OOpen a URL in the browser of your choice
  • spaceQuick Look — the full item, big
  • PPin an item so it never expires
  • LMark as secret — masked here, kept in your Keychain
  • TTransform: trim, change case, escape JSON
  • RRename an item so you find it later
  • EEdit the content itself, re-detected on save
  • SSave the item to a file
  • Delete it
  • escGone. Back to work

Nothing to memorize first. Hold and the panel labels every shortcut as you look at it, and each one is spelled out in a menu next to the actions.

Private early access

Have a code?

Rakkun is coming to the Mac App Store. It’s in private early access right now — enter your access code and you’re ten seconds from installing.

Early access is the full app. Every type, every action, nothing gated — the App Store release will have a free tier and a one-time unlock, but early access builds come fully unlocked.

Signed & notarized by Apple. Drag Rakkun to your Applications folder and double-click — it opens like any other Mac app, with no Gatekeeper warning.

No code yet? Request access — we onboard a few developers every week.
