License Compatibility Checker

Put the licenses of the works you want to combine into one bundle. The DALICC reasoner checks them against each other. When they fit together, pick the license you would like to publish the result under, and the checker composes a licensing statement you can download and keep with your work.

DALICC checks licenses against their models and does not replace legal advice. For a decision that matters, ask a lawyer.

Every step of the check works without JavaScript: each button reloads this page with the result of that step.

Dependency graph

The reasoner decides what conflicts with what from this graph. The default is the curated DALICC graph; see what it says, or read how the check uses this graph. While you are signed in, your own graphs and the ones shared with you are offered here too, drafts included, so you can try a graph out before you publish it. Whichever graph you pick is written into the statement you download.

What the check cannot see

The check compares what the licenses permit, prohibit and require as DALICC models them, and the compatibility a license record grants by name, in the direction it is granted (for example CC BY-SA 4.0 into GPL-3.0). It does not see compatibility that no license states, clauses the vocabulary cannot express (for example a ban on selling or on production use), or the license texts themselves. Read the license texts before you combine them. How the check works.

Define target license

Pick the license you would like the combined work to carry. It is written into the license statement you download.

Select target license

Or enter the id of an unlisted target license

Licenses created with the License Composer are unlisted. They do not appear in lists, search results or this dropdown. To use one, enter its 32-character id.
