Keep a local clipboard history with collections, search, and sensitive-item rules
Unlimited history plus the source app plus a timestamp is not a buffer. It is a diary you never agreed to keep.

Our verdict, the regret score and everything below it. Editorial and unsponsored — nobody can pay to be moved.
The honest answer
why the verdict is what it is
Two entries here already make the arguments you would expect — that clipboard history is a plaintext log of your passwords, and that cross-device sync is the genuinely hard part — and both still apply. What PastePal adds is the word "unlimited". Its pitch is unlimited history with a fast index and search, plus smart detection that records which application each item came from. Read that as a schema and it stops being a buffer: you are building a timestamped, full-text-searchable table of every fragment that passed through your hands, tagged with the app you were in at the time. Even the rows with no secret in them reconstruct your working day minute by minute, and the search box is what turns a pile into a record. None of it can hurt anybody but you, all of it runs on one machine, and it is a satisfying build — so ship it. Just decide the retention policy on day one, because nobody ever goes back and adds forgetting to something that already works.
What actually breaks
not "if". the specific failures.
- The index, which is the feature: full-text search means the API key you pasted in March is two keystrokes away in August, and you will have forgotten it is in there
- Item metadata, quietly — source application, timestamp, character count — which reconstructs a working day even for the items whose contents are dull
- Retention, because "unlimited" is a decision dressed as a capability, and adding expiry to a store that already holds three years is a migration nobody wants to run
- Disk, once images and files are captured: every screenshot you copied is a full-resolution PNG in your database, and the database is now measured in gigabytes
- Spotlight and Time Machine, which will cheerfully index and back up an unexcluded store, so one deleted secret now exists in three places you never thought about
- The polling loop racing a password manager that clears the pasteboard after thirty seconds — sometimes you win, and winning is the bad outcome
- Restore, the sharpest edge in the app: recovering from a backup resurrects the items you deliberately deleted, and nothing warns you
- Rich-text representations kept "just in case", which carry the source URL, its tracking parameters and occasionally the author's name into wherever you paste next
Is that you?
the verdict is a default, not a law
- It runs on one Mac, stores history inside the app container, and speaks to no network
- The store is encrypted with a Keychain key and excluded from Time Machine, Spotlight and every sync client on the machine
- You picked a retention limit before you wrote the search box — a count, an age, or both
- You are fine re-fixing pasteboard behaviour roughly once per macOS release
- The database lives in Documents, Desktop, iCloud Drive or a Dropbox folder
- "Unlimited history" is on the feature list and "delete" is not
- You are storing image and file items at full fidelity with no size cap, on a laptop with a small SSD
- You plan to hand it to other people, at which point notarisation, entitlements and explaining the Accessibility prompt become a support job you did not price in
If you build it anyway
the checklist, then the prompt that enforces it
- Write the retention rules before the search UI. Cap by count and by age, expire on a timer, and make deletion remove the row, its index entry and its thumbnails.
- Encrypt the store with a key from the Keychain, keep it in the app container, and set the Time Machine and Spotlight exclusions explicitly rather than assuming the container is private.
- Honour org.nspasteboard.ConcealedType and keep an ignore list of applications with the common password managers pre-populated. A capture that never happened cannot leak.
- Store the minimum metadata that makes search work. Source bundle ID and timestamp are useful and they are also a surveillance log — if you keep them, expire them on the same clock as the content.
- Cap image and file items by byte size, keep a thumbnail rather than the original above the cap, and show in the UI which items were truncated.
- Give backups their own decision: either exclude the store entirely, or warn on restore that deleted items are about to come back.
- Never write a clipboard item to a log line, a crash report or an analytics event. There is no analytics in this app.
I am building a macOS clipboard manager for myself — unlimited-feeling history,
fast search, collections, and the source app recorded per item. It will hold
passwords, one-time codes and API keys whether I plan for that or not. Work in
this order, and argue with me when I ask for a shortcut.
1. Design the store and its retention policy before any UI. Every item gets a
created-at and an expires-at. Nothing is written without both.
2. The store lives in the app container, in SQLite, encrypted with a key from
the Keychain. Never Documents, Desktop, iCloud Drive or a Dropbox folder.
3. Set the Time Machine exclusion and the Spotlight no-index flag on the store
explicitly, and tell me in the README which one protects what.
4. Implement delete before search. Deleting an item must remove the row, its
full-text index entry, any cached thumbnail and any preview file. Show me a
test proving a deleted item is unfindable.
5. Give me one action that destroys everything by removing the file rather than
emptying a table, plus a per-app "forget everything from this app".
6. Capture rules next: honour org.nspasteboard.ConcealedType, and skip capture
when the frontmost app is on an ignore list that ships populated with the
common password managers.
7. Only then build search. Index the content, not the metadata, and do not log
the queries anywhere.
8. Record source application and timestamp only if they expire with the item.
Treat that pair as sensitive on its own — it is an activity log.
9. Cap image and file items by byte size. Above the cap keep a thumbnail and a
note, not the original, and show me the store's size in the UI.
10. On restore from a backup, warn loudly that deleted items may be returning
and offer to re-apply the expiry rules immediately.
11. Never write clipboard contents to a log, a crash report or telemetry.
12. Out of scope: iCloud sync, an iOS companion, distribution, licensing. If I
ask for sync, make me design key handling and deletion propagation first —
the app I am copying sells all of it for $14.99 once.That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.
their build prompt ↗Or don’t build it
the boring option, and the way back out
$14.99 once, with no subscription and nothing to forget to cancel, is close to the cheapest exit on this site — and it buys the two things a weekend does not: the iOS half, and somebody else re-fixing pasteboard behaviour every time macOS changes it. Build your own because you want the retention rules to be exactly yours, or because you enjoy AppKit. Not to save fifteen dollars.
Deleting the app is most of it, with one deliberate step: remove the store yourself instead of leaving three years of copied secrets in Application Support long after the thing that wrote them is gone. Collections are the part with real value, so give them a plain export — one JSON or Markdown file of your saved snippets — because those move into any other clipboard manager, and the history behind them should not move anywhere at all.
The canonical open-source macOS clipboard manager, actively maintained, with the ignore list, concealed-type handling and history limits already solved.
Active cross-platform text expander — the better reference if what you actually want is the saved-snippets half rather than the history.
Questions
Two other clipboard entries already exist here. What is different about this one?
The credentials argument is settled and shared, and the sync argument belongs to Paste. PastePal's distinguishing claim is unlimited history with fast search plus per-item source detection, and that combination is a different object from a clipboard buffer — it is an append-only, searchable record of your day. The engineering follows: retention, deletion that actually deletes, and keeping the file out of backups matter more here than anything about capture.
Is recording which app an item came from really worth worrying about?
On its own, no. Combined with a timestamp and three years of retention it is a minute-resolution log of which applications you used and when, sitting in the same file as the secrets. If you keep that metadata, expire it on the same clock as the content and you have neutralised it for the cost of one column in a delete query.
Why is buildEase 7.0 when the upstream estimate is one sitting?
Because it is AppKit and a pasteboard rather than React and a REST API, and that is consistently where agent output gets weaker: global hotkeys, menu-bar lifecycle, pasteboard type handling, permission prompts. The capture loop really is an evening. Encrypted storage, expiry that survives a restart, and a delete path that also clears the search index are the rest of the weekend.
Every week, someone ships something they shouldn’t have.

The clipboard manager is a day's work. Making the same secrets appear on three devices is the actual product.
A clipboard manager is a plaintext log of every password you copied. Build it — keep it off iCloud.
A launcher is a fuzzy search over things you already have. Nothing here can hurt you.
