Datomic Pro Pricing
A Datomic Pro license is priced by the number of simultaneous processes using Datomic software (peers + transactors) in production at your company. Testing and development use against non-production databases does not count towards your limit.
Buying a license gives you perpetual use of the current version, and includes 12 months of software maintenance (updates and access to online support) commencing from the date of purchase. Renewing maintenance is entirely optional. Beyond this initial 12 month period, you may renew your software maintenance for another 12 months* at our discounted renewal prices.
With your license you will get a key that will authorize your storages for the number of processes you have paid for. This key must be installed in any storage you intend to use. Datomic Pro software is not redistributable. Please contact us for OEM pricing.
*Maintenance renewals commence from the expiration of your active maintenance period, regardless of when the maintenance renewal is purchased. If you intend to renew, we recommend renewing at least 30 days before expiration.
You can upgrade Datomic at any time. Upgrades include 12 months of software maintenance commencing from the date payment is processed. This will override any existing maintenance period.
