ObjectDB License

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

Server License

Object DB 2.x Server License costs £300 and includes all version 2.x updates.

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

Site License

Object DB 2.x Site License costs £1,800 and includes all version 2.x updates.

The site license covers installation of Object DB on all the computers of one company or organization in one building, and in addition covers also installation of Object DB on:

  • Home computers and laptops of employees in that workplace.
  • Servers that are leased or rented from third party web hosting and / or cloud hosting companies (including shared web hosting and VPS), if the hosted applications that use Object DB are developed and managed only by employees in that workplace.

OEM License

Object DB 2.x OEM license enables distribution of Object DB runtime bundled in a product to unlimited number of end users.
