Freeware

Freeware is computer software that is available for use at no cost or for an optional fee.^[1] Freeware is different from shareware; the latter obliges the user to pay (e.g. after some trial period or for additional functionality).

The only criterion for being classified as freeware is that the software must be fully functional for an unlimited time with no cost, monetary or otherwise. The software license may impose restrictions on the type of use including personal use, individual use, non-profit use, non-commercial use, academic use, commercial use or any combination of these. For instance, the license may be "free for personal, non-commercial use".
