FACTUAL COMPARISON
Orchestration Engines Compared
Every Quox cell was re-checked in source for this build. The Ruflo, CrewAI and LangGraph columns stand as last checked in March 2026 against public documentation and source, not a fresh audit. The band under the table names what was verified and what was not.
In plain words
What it is, where it lives, when to reach for it
- What is it
- A factual comparison of multi-agent orchestration engines: Quox against Ruflo, CrewAI and LangGraph.
- Where do I use it
- Right here, in one feature-by-feature table covering the four engines.
- When would I use it
- When you are choosing an orchestration engine and want the differences stated without marketing.
- How do I use it
- Read the table, then the verification band beneath it, which says how each claim was checked.
Last updated March 2026. Ruflo data from public repo + docs. CrewAI from v0.x docs. LangGraph from LangChain docs.
Where these numbers come from
- The agent-count row now resolves from the site's facts module rather than a typed cell: 49 is the audited persona population, its definition and its known defects are recorded in src/content/facts/facts.json, and the row cannot drift from the rest of the site again. It has previously read 25 and 37 while other pages read 32, 22 and 19
- Topology (4 modes), the epsilon-greedy learning router, the default 3-failure circuit breaker, domain-aware fallback routing, cron overlap prevention + timezone support, and the JSON Schema output validator were all confirmed present in source this session
- Not every Quox cell above is equally mature: budgets and HITL are Beta with named gaps in the dashboard’s own status docs (see the Agentic Teams honest band below the fold on that page), a single checkmark here does not mean production-hardened
- Ruflo, CrewAI and LangGraph cells were not re-verified this session: this environment has no live web access, so those columns stand as last checked (March 2026) against public docs and source, not a fresh audit
