Omeka and similar tools publish collections online as exhibits; they are not accession registers. A few free tools for personal collections exist but lack accession numbers and registers.

Questions that decide it

  • How many objects, and how many people enter records at once? One registrar on one computer needs far less than a staff of five.
  • Which computer? A Mac, a shared office PC and a volunteer's laptop narrow the list quickly.
  • Who backs it up? Hosted plans back up for you; anything on your own computer needs a habit.
  • Must the collection be online for the public? If so, a hosted plan or a publishing tool is part of the answer.
  • What does it cost over five years, including hosting, not just the first year?

Worked example: where Curatorbook fits, and its limits

Curatorbook runs in the browser on a Mac or PC with nothing to install and no account. The catalogue lives in that browser's storage. Safari deletes a site's stored data after 7 days of browsing without a visit to the site, and any browser can lose it when site data is cleared, so Curatorbook reminds you to save the catalogue file (a zip of the records and photos) whenever it holds changes the last file does not, and asks the browser to keep its storage where the browser allows.

It is one registrar's catalogue: it does not share records between people or publish them online. Everything in it is free today. When a collection outgrows it, the CSV export is the way to a larger system.

Common mistakes

  • Comparing first year prices and not the yearly hosting that follows.
  • Choosing a server product with nobody to maintain the server.
  • Keeping the only copy of the catalogue on one aging computer.
  • Buying before cleaning the numbers, then importing the same problems.
  • Picking a publishing tool when what is needed is an accession register.

Do it in the catalogue

Open the catalogue to number an accession and its objects, add photos and locations, and print the register, labels and receipts. Everything stays in this browser; nothing is uploaded and there is no account. Save the catalogue file after every session.

Frequently asked questions

Is there free museum collection software for a Mac?

Yes. Browser based tools run on a Mac, including hosted free plans with small limits and Curatorbook, which keeps records in the browser on your own computer. PastPerfect 5.0 runs on Windows.

Are these prices current?

They were checked on 28 September 2026 on each vendor's own pricing page. Prices change; check the vendor's page before you buy.

Does Curatorbook follow the Spectrum standard?

It paraphrases common procedures such as object entry, accessioning, location, inventory, cataloguing and loans, but it does not claim compliance with Spectrum or any other standard.
