Every new sign-in to the application needs a connection; the Pro allowance covers existing sessions only. The licence heartbeat carries allowlisted feature counters, each user's monthly usage totals (the counts your plan limits), product version and platform, never model content, project names or file paths. AI assistance uses your configured provider and may incur separate provider costs.

System requirements

A desktop install,
not another server to run.

D3rive runs as a local application on your workstation. The installer sets up everything it needs, including its own database.

Operating system
Windows 10 or Windows 11, 64-bit
Installation
Permission to install software on the machine
Database
Included with the installer; nothing to install separately
Connectivity
Internet access to sign in and validate the licence (Trial, Pro, Team). Enterprise can run fully offline.
AI copilot
Optional. Uses an API key from your own AI provider; the provider bills you directly.
Account
A D3 account from this site: the same sign-in for the site and the application

architecture question.

Free for 14 days on Windows 10 and 11. No payment details, and your models stay on your machine.
