OpenBox

OpenBox provides runtime governance for AI agents — cryptographic verification of agent actions, decentralized identity for agents, and protocol-aware policy enforcement across development, execution, and monitoring phases, working with frameworks including Temporal, LangGraph, LangChain, and n8n. Its five-phase trust lifecycle (assess, authorize, monitor, verify, adapt) is a considered approach to agent governance rather than a single static permission check, and it's designed as "one SDK, no architectural changes" — meant to integrate into an existing agent framework rather than requiring a rebuild. A published press release, working registration, and documentation point to real, current activity, though the site alone doesn't confirm production-scale customer deployments beyond what's stated. It offers no usage limits and no credit card required to start; specific paid pricing isn't disclosed and requires checking the pricing page. Good fit for a team running AI agents across multiple frameworks that wants cryptographically verifiable governance and accountability, particularly in a context where agent actions need to be audited after the fact.
