Why consider the swap

If you currently rely on Amazon Neptune and want more control over data, lower long-term costs, or a open-source licensing model, TerminusDB covers most of the same ground.

What you trade off

Most open-source alternatives require more setup than their commercial counterparts and may lag on polish, mobile apps, or ecosystem integrations. Check the project’s documentation for current feature parity with Amazon Neptune before committing.
