ObjectDB License

Free License

ObjectDB can be downloaded and used at no cost (including commercially) with the restriction of a maximum of 10 entity classes and one million entity objects per database file. This could be useful for small projects, academic assignments, evaluation and learning. ObjectDB is a commercial software and using it without these restrictions requires purchasing a license.

You are encouraged to test ObjectDB before purchasing a license.

Server License

ObjectDB 2.x Server License costs £500 and includes all version 2.x updates.

A server license covers one installation of ObjectDB on a single computer. A license is required for every machine on which ObjectDB databases are managed, but using ObjectDB on client machines merely to access remote ObjectDB databases (for which licenses have been purchased) does not require additional separate licenses.
