Open Multi-Agent
Open Multi-Agent is a TypeScript multi-agent framework that allows self-hosting for verifiable agent runtime, durable approvals, and tamper-evident run records.
Open Multi-Agent is a TypeScript-native framework for building and running multi-agent systems on self-hosted infrastructure. The runtime allows organizations to define consequential actions that wait for durable, tamper-evident approvals. Every execution generates a run journal that can be verified offline, byte for byte, to ensure integrity. It supports integration with various models, including those running in cloud environments, locally, or in air-gapped setups using your own credentials. The system supports three execution workflows: individual agent runs, task DAG execution, and coordinator-led team goals.
