Clipboard Manager for Mac with Developer Tools

What DevClip does

Clipboard history on macOS, one keystroke away

The panel opens with ⌘⇧VCommand-Shift-V (Command-Shift-V) over whatever you are doing, without switching apps or stealing focus from your editor. Arrow keys move, ⏎Return copies, and ⌘1Command-1 through ⌘9Command-9 grab one of the first nine directly.

• Code is detected and highlighted automatically — a one-line curl counts, not just a whole file. You can also set the language by hand from Auto plus 21 others.
• ⌥VOption-V (Option-V) copies the previous item without opening anything. Press it again within three seconds to keep walking backwards.
• Drag a card straight out of the panel into another app: as a file, an image, a URL or plain text.

Developer tools, in the clipboard

It is a JSON formatter, a JWT decoder, a hash tool and a diff viewer, in the same window as the thing you copied. Open any text clip with ⌘⏎Command-Return (Command-Return) and the transform menus apply to whatever you have selected — or to the whole clip if you have selected nothing. It all runs on your Mac; none of these tools sends your text anywhere.

• Format: JSON pretty-print (sorted keys) and minify · SQL format and minify · Mongo query format · XML → YAML and YAML → XML.
• Convert: Base64 · URL encode and decode · unix timestamp ↔ local date · camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE.
• Pro tools: JWT decode (header and payload, pretty-printed) · SHA-256 · MD5 · AES-GCM encrypt and decrypt with a passphrase.

Diff two clipboard items

⌘-click two text cards and press ⌘DCommand-D. DevClip reads them out as a unified diff, top to bottom: removed lines carry a − in the gutter and a red wash, added lines a + and a green one, and shared lines stay plain.

• Works on anything textual you copied: two API responses, two config blocks, the version of a query before and after someone edited it. Images and files can't be diffed.
• Compares up to 5,000 lines per side. Anything past that is left out of the comparison.
• Part of Pro, and free during the 30-day trial.

An editor with syntax highlighting

⌘⏎Command-Return on a card opens a real editing window: line numbers, monospaced text, undo, and no autocorrect or smart quotes getting in the way of your code.

• Find and replace is built in: ⌘FCommand-F to find, ⌘GCommand-G and ⇧⌘GShift-Command-G to step, ⌥⌘FOption-Command-F to replace. ⌘RCommand-R is bound to replace as well, for the JetBrains muscle memory.
• Syntax highlighting uses highlight.js, with Auto plus 21 languages you can pick from.
• Edits are saved back to the clip with ⌘SCommand-S. Unsaved drafts survive closing the window and are marked as unsaved when you come back.

Pro adds a sidebar of your recent items inside the editor, so ⌘↑Command-Up and ⌘↓Command-Down move between clips without going back to the panel.

Pin, file and tag what you want to keep

The history prunes itself. Anything you pin, or put in a folder, is exempt — from the item limit, from the age limit, and from Clear History.

• ⌘PCommand-P pins an item. Pinning does not reorder anything; it just means the item stays.
• Folder tabs sit along the top of the panel, six colours, created and renamed from the panel itself. Deleting a folder unfiles its items rather than deleting them.
• Titles and tags are edited inline on the card, and both are searchable. Untitled cards borrow a name from their own contents.

Privacy: what DevClip stores and what leaves your Mac

No permission prompts to get started.

DevClip needs no system permissions to run. The global shortcut uses a Carbon hotkey, which asks for nothing. Accessibility permission is requested only if you turn on "paste on select" in Settings, and it is used only to send a ⌘VCommand-V keystroke — DevClip installs no event tap and never reads what you type.

Sandboxed, with four capabilities.

The App Store build ships exactly these entitlements: outbound network, app-scoped bookmarks, read-only access to files you pick, and the sandbox itself. There is no entitlement to accept incoming connections, so the app cannot listen for them. No camera, microphone, contacts, calendars, location, photos, or temporary exceptions.

Encrypted before it is written to disk.

Clip text, titles, tags and image data are encrypted with AES-256-GCM before being written. Some things are not encrypted: the name of the app you copied from, timestamps, item sizes, the detected language, folder names, and a SHA-256 hash of each clip. The encryption key is a permissions-restricted file in the same folder as the database, which means it protects against a tool that reads the database and misses the key — it is not protection against someone with your unlocked Mac. FileVault is what protects a stolen disk.

No analytics, no telemetry, no crash SDK.

There is no analytics service, no telemetry, no crash reporter and no auto-updater in DevClip. The only third-party code in the app is Highlightr, which does syntax highlighting and makes no network requests. Pro licensing is checked entirely on your Mac — there is no activation server to phone home to.

One network feature, and it is a switch.

Link previews are on by default. When a card for a copied link appears on screen — not when you copy it — DevClip requests up to three things: the page itself, that host's favicon, and the preview image the page declares, which is often on a different host. Requests time out after three seconds, each link is fetched at most once and then cached locally, and addresses DevClip recognises as localhost or private numeric addresses are skipped. Turn it off in Settings → Privacy and DevClip makes no network requests at all, apart from the App Store checking your purchase.

Passwords.

Anything copied with the standard macOS concealed-content marker is never recorded, and 1Password and KeePassXC are on the excluded-apps list out of the box — their copies are discarded before anything is written. Password-shaped text copied from a browser is masked on the card and deleted automatically after three minutes, unless you pinned it or put it in a folder. That masking only covers ten known browsers and only text that looks like a password, so treat it as a safety net, not a guarantee: a password copied from a terminal or a native app is stored like any other clip.

What DevClip doesn't do

Written down so you find out here rather than after installing.

• No iPhone or iPad app, and no sync. Nothing goes to iCloud, and there is no way to see your Mac's clipboard on another device. If that is what you need, other clipboard managers do it and this one doesn't.
• Mac App Store only. No direct download, no Homebrew cask, not on Setapp.
• Not open source. If inspectable code is a requirement, there are good open-source clipboard managers and DevClip isn't one of them.
• No text recognition in images. Screenshots are stored and shown, not read.
• No AI features.
• No keyword-triggered text expansion. DevClip stores and transforms what you copy; it doesn't expand abbreviations as you type.
• No command line tool, no Shortcuts actions, no AppleScript automation.
• macOS only. macOS 14 Sonoma is the floor.

Pricing — one-time purchase, no subscription

Download it free, use everything for 30 days, then decide. The trial starts the first time you launch DevClip. It never asks for a card, because the download itself is free.

The boring details, stated plainly

• It is one non-consumable in-app purchase on your Apple Account. There is no renewal, no second tier and no upgrade pricing. "Restore Purchase" is in Settings.
• $4.99 in the US, ₩7,700 in Korea. Other storefronts are Apple's conversion of the same price tier.
• Apple handles payment. DevClip only reads whether the purchase exists, and never sees card details.
• Refunds go through Apple, at reportaproblem.apple.com.
• When the trial ends, the free limit applies again. The next time you copy something, unpinned history is trimmed back to the newest 50 items. Pinned items and anything in a folder are never trimmed — so pin or file what you want to keep before day 30.

Questions about DevClip

Who makes this

DevClip is made by one person, under the name nuasa. It shipped on the Mac App Store on 27 July 2026 and is on version 1.0.5.

It has almost no users yet, so there are no reviews to point at — which is exactly why this page describes what the app does in specifics you can check after installing it, rather than in adjectives.
