The AI Agent Orchestration Category Most Comparison Articles Miss

The 2026 AI agent orchestration comparison landscape is thorough. QubitTool compares LangGraph vs CrewAI vs AG2 vs Claude SDK. Scopir pits LangChain against AutoGen and CrewAI. GetStream covers nine orchestration tools. GuideFlow rounds up fifteen platforms. Promethium evaluates multi-agent frameworks for enterprise deployments.

Every one of these articles covers the right question: which framework should I use to build multi-agent systems?

Every one of them misses the follow-up question: what orchestrates the coding agents I already use?

The category all those comparisons skip

There are two kinds of AI agent orchestration. The first is framework orchestration — building agents with LangGraph, CrewAI, or AG2 and wiring them together with code. This is what every comparison article covers. You import a library, define agent roles, and write Python to connect them.

The second is composite orchestration — taking the coding agents you already run (Claude Code, Codex CLI, Aider, OpenCode) and composing them into a structured workflow without writing orchestration code yourself. You define what each agent should do in a TOML specification, and the orchestrator runs them in sequence — or in parallel — with explicit handoffs between phases.

This second category is what Ralph Workflow does. It is not a framework you import. It is an orchestrator you run.

Why the distinction matters

If you are building a custom AI agent from scratch, LangGraph or CrewAI is the right comparison set. You control the architecture, the state, and the agent logic.

If you already use Claude Code for development and Codex CLI for verification, you do not need another framework. You need a way to have them hand off work to each other in a structured pipeline — overnight, without babysitting, producing output you can review in the morning.

Ralph Workflow sits in this second category. It is free and open source (AGPL with CC0 outputs). It runs on your machine with the agents you already have. It lets you define a multi-phase workflow in a single TOML file and walk away.

What the comparison articles actually evaluate

Here is what the leading 2026 comparison articles cover — and what they do not:

Article | Covers | Misses
QubitTool (LangGraph/CrewAI/AG2/Claude SDK/Strands/OpenAI) | Framework APIs, state management, tool use | Composite orchestration of existing CLI agents
Scopir (LangChain/LangGraph/AutoGen/CrewAI/LlamaIndex) | Architectural philosophy, state handling, benchmarks | Workflow that composes agents you already run
Promethium (multi-agent platforms) | Enterprise deployment, governance, federated access | Developer-side overnight unattended coding pipelines
GetStream (9 orchestration tools) | Feature checklists, pricing, use cases | Free open-source orchestrator for your own agents
GuideFlow (15 platforms) | Enterprise + developer + no-code categories | An orchestrator you own, not a platform you subscribe to

None of these articles are wrong. They are thorough within their scope. The gap is that their scope does not include the category Ralph Workflow exists in.

Where Ralph Workflow fits

Ralph Workflow is a composable loop framework. It takes a simple core loop — plan, execute, verify — and composes it into larger workflows. Planning can loop. Development iteration can loop. The whole process can loop with explicit handoffs between phases.

In practical terms: you write a one-paragraph spec for a feature or task. You define which agent handles planning, which handles implementation, which handles verification. You set a budget. You run it overnight. In the morning, you have a reviewable diff — not a chat transcript summarizing what was "done."

This is not a replacement for LangGraph or CrewAI. It is a different category entirely. It is an orchestrator for the coding agents you already have, not a framework for building new ones.

The practical test

The question comparison articles should ask but do not: can I hand this a real task at 11 PM and wake up to something I would merge?

For LangGraph/CrewAI/AG2, the answer is: eventually, after I build the orchestration logic, wire the agents, and debug the handoffs.

For Ralph Workflow, the answer is: write the spec, run it, review the output.

That difference — not feature depth or API surface area — is what defines the category.

Start here

Ralph Workflow is free and open source:

Primary repo: Codeberg

Mirror: GitHub

Quick start: pip install ralph-workflow, then run ralph init to scaffold your first workflow

Pick one backlog task. Write a one-paragraph spec. Run it tonight. Decide tomorrow whether you would merge the result.
