Questions
Is the core really open source?
Yes. The embedded library, MCP server, and governance features ship as the open-source core. The trust suite is yours to run — every governance claim is a gate you can re-execute.
Where does my data live?
In your environment. Heartwood is embedded and runs beside your systems of record. Self-hosted by default; nothing is shipped to us.
How is this billed?
Professional is billed annually through Edukas Solutions’ existing Stripe infrastructure. Enterprise remains sales-led and is billed by custom quote.
What do paid tiers actually add?
Support SLAs, signed releases and rapid patching, policy/subject-partition design review, KMS/HSM-compatible key custody, custom adapters, and audit consulting.
