Screenshot of OpenFlow – Ultimate Agent Orchestration

OpenFlow is a visual builder for orchestrating multi-agent AI workflows: drag role cards onto a canvas, wire a pipeline (planner → architect → coder), save it and run parallel agents. It ships as a fork that sits on top of the opencode headless engine (opencode serve), keeping all OpenFlow-specific code in packages/flow so the upstream engine remains untouched. The repository includes extensive documentation and artifacts (AGENTS.md, FLOW.md, READMEs in many languages), SDKs, scripts and dev tooling to build, run and extend agent-based pipelines.

Installation and operation are practical and scripted: Bun and Git are required, bun install pulls the workspace, and OpenFlow uses ports 4096 (engine) and 5174 (canvas). A single command (FLOW_MANAGE_SERVER=1 bun openflow.ts) starts both processes with an option for the canvas to manage and restart the engine; platform shims and explicit server/client commands are provided. The README details troubleshooting (port conflicts, database-locked by another engine, Windows PowerShell script restrictions), runtime flags (project, server-port, built, manage, dry-run) and model access: a free opencode “zen” tier works without keys, while an in-app API Keys panel imports provider credentials (including opencode CLI auth.json) for paid models.
