Where freedom meets persistent identifiers

Create free, persistent, DOI-like identifiers for your digital objects of any kind.

How FreeDOI Works

Simple, free, and persistent identifiers for your digital objects

Create a FreeDOI

FreeDOIs combine a prefix (20-29), your unique suffix, and an identifier that you choose.

Link to Your Content

Connect your FreeDOI to the URL of your digital object - papers, datasets, software, or any digital resource.

Share & Cite

Use your FreeDOI in citations, references, and sharing. It will always resolve to your content.

Update When Needed

If your content moves, simply update the target URL. Your FreeDOI remains the same.
