KDCube — AI for your customers

The self-hosted runtime that handles tenant isolation, per-customer spend caps, and audit trails — so you can ship AI features enterprise buyers will approve.

Built on ReAct v2, our open-source timeline-first agent runtime. The ReAct loop — Reason, Act, Observe — is what makes an agent an agent; it is the soul of the runtime. Works with LangGraph, CrewAI, or plain Python as the authoring layer.

• Give every customer their own wallet — spend caps enforced before the model runs, not after.
• Keep customer data on your side of the firewall — self-host on your VPC, your hardware, your rules.
• Prove what happened, per turn — every turn stored as typed blocks (turn_id, tenant, agent, tool calls, cost, outcome) append-only in Postgres on your infrastructure.

Pass enterprise security review on day one — skip the 6-month platform build, close the deal this quarter. See Product.
