Specula · Latin for watchtower

Never again
“Your disk is almost full.”

Specula keeps a calm, quiet watch over your Mac — and gives back the space your tools silently take. You just get to work.

It always happens at the worst moment.

Mid-build.

Mid-deadline.

Mid-thought.

Suddenly you're not building anything. You're hunting for gigabytes in folders you've never heard of, deleting things you hope you won't need.

Your disk is almost full.

Save space by optimizing storage.

room to breathe

Now imagine the opposite.

That quiet feeling of room.

  • Docker build cache21.4 GB
  • node_modules in projects you haven't opened in months6.3 GB
  • Xcode symbols for old iPhones5.9 GB
  • The same installer, downloaded twice4.2 GB
  • Claude Code versions you'll never run again0.6 GB

Not another cleaner.
A calmer Mac.

Three feelings Specula gives back.

Foresight

You'll know weeks ahead.

Specula notices the slow creep and tells you when your disk will fill — long before macOS starts to panic.

Relief

The hidden weight, found.

Docker layers, Xcode leftovers, forgotten Claude and Codex versions. Gigabytes you didn't know you were carrying, surfaced in seconds.

Trust

Nothing vanishes without you.

You decide, always. Specula protects what matters, explains what's safe, and offers the Trash first.

Quiet by design.

It lives in your menu bar and speaks up only when it matters. The rest of the time, you forget it's there — which is exactly the point.

Specula's overview: free space, a forecast of when the disk fills up, and the biggest things to reclaim.

It never leaves your Mac.

No account. No tracking. Specula goes online only to check its license, look for updates and — if you allow it — send crash reports. What it learns about your disk stays on your disk.

It never guesses for you.

Every number is measured, every suggestion explained. Your files, your call.

It knows developers.

Docker, Xcode, Gradle, node_modules, Claude, Codex, Cursor — the places space really goes.

Pay once.
Keep it for good.

No subscription, no account. One license for your Mac, with a year of updates included.
