Our suggestion based on what it does, not a feature-by-feature comparison.

Make money with it

A freelancer could offer a secure document-handling setup for clients, such as setting up and training them on encrypted cloud vaults.

An idea, not financial advice. Check the licence before charging for anything built on it.

Ways a business could use it

  • Protect client contracts, invoices and financial records stored in shared cloud folders, helping with data protection duties
  • Avoid paying for a separate encrypted cloud storage service by encrypting files in the cloud storage you already use

Can you use it commercially?

Free to use. Anything you distribute that includes it must be open-sourced under the same licence.

Not legal advice. Read the project's licence file before building a product on it.

Getting it running

Download the native installer for Windows, macOS or Linux from cryptomator.org; building from source needs JDK 26 and Maven.

Follow the official instructions in the project README.

Things to check

  • If you forget a vault password and lose the recovery key, the files cannot be recovered
  • Dual-licensed: GPL-3.0 for open-source use, with a commercial licence needed for some commercial redistribution
  • Relies on donations and sponsors for funding
