UniDoc is licensed as AGPL software (with extra terms as specified in our license).

AGPL is a free / open source software license.

This doesn't mean the software is gratis!

Buying such a license is mandatory as soon as you develop activities involving UniDoc without disclosing the source code of your own applications under the AGPL license. These activities include offering services as an application service provider or providing an over-network based application programming interface (API), creating or manipulating documents for users in a web/server/cloud application, incorporating UniDoc into a closed source product.
