Rebuno is an open-source execution runtime for production agents. It records every tool call and LLM call as a durable step. Interrupted runs resume from the last recorded step instead of starting over. Any step can be allowed, denied, or held for human approval.

Quickstart

Start the dev kernel, run an agent, and create your first execution.

​
Concepts

Architecture

The domain model, state machines, and how durability works.

Agents

Clients

Tools and effects

LLM calls

Intercepting provider requests so they replay durably.

Policy

The rule language for allow, deny, and require-approval.

Events

The event taxonomy and payloads behind every projection.

Live streaming
