Pricing questions
Is SpanForge really free?
Yes. The full SDK — all 11 services — is MIT licensed and available on PyPI at no cost. You can instrument your first AI action, generate a signed evidence bundle, and hand it to your compliance team before you ever speak to us.
What does the Enterprise plan include?
The Enterprise plan layers human expertise on top of the SDK: architecture reviews, evidence walkthroughs, framework mapping to your specific obligations, and a committed support SLA. Contact us for a scoped proposal.
Do I need a contract to start?
No contract is required to use the open-source SDK. Enterprise plans involve a statement of work, but you can evaluate everything before committing.
How does support work on the free tier?
