# SynthBoard vs CrewAI

> CrewAI is a developer framework for building multi-agent systems in Python. SynthBoard is the productized AI Boardroom for decisions that matter. They share the multi-agent architecture but live in different layers of the stack — and play well together.

## TL;DR

| | CrewAI | SynthBoard |
|---|---|---|
| Layer | Developer framework | End-user product |
| Audience | AI engineers |  Anyone making strategic decisions |
| Setup | Hours to weeks of code | Minutes |
| Personas | You write each agent | 24 pre-built expert Synths |
| Routing | You pick per agent | Multi-LLM, automatic |
| Synthesis | You build it | Built-in |
| Memory | You design persistence | Cross-session, automatic |
| Outcomes | You instrument | Inferred from connected tools |
| UI | Whatever you build | Web app + MCP + REST API |

## What CrewAI is for

CrewAI is excellent if you are a developer building multi-agent infrastructure. You want fine control over agent definitions, task graphs, tool integrations, and execution flow. You are willing to invest engineering time to get a custom system.

If you are building a product that has multi-agent reasoning *inside* it — research assistants, content generation pipelines, custom analyst agents — CrewAI (or LangGraph, AutoGen) is a sensible foundation.

## What SynthBoard is for

SynthBoard is excellent if you are a founder, operator, executive, consultant, or anyone who wants to *use* a multi-agent system to make decisions, without building one. You want to convene a board, run a session, and get a synthesized recommendation in minutes.

The tradeoff: you give up the ability to write your own agents. You get an opinionated, productized board with 24 expert Synths and 10 session modes.

## They are complementary

If you are building agent infrastructure with CrewAI and you want a high-quality decision-board surface inside it, SynthBoard's REST API and MCP server let you call a board from a CrewAI agent. The CrewAI agent does the orchestration; the SynthBoard board provides the structured deliberation when you need a real recommendation.

This is the pattern many of our enterprise customers use: their internal agents call SynthBoard for any decision step that requires multi-perspective reasoning, then continue their flow with the synthesis as input.

## When to pick which

- **Pick CrewAI** if: you are an engineer, you want full control, you are building a multi-agent product yourself.
- **Pick SynthBoard** if: you are an operator, you want decisions made with multi-agent reasoning, you do not want to write code.
- **Pick both** if: you are building agent infrastructure that needs a decision-quality reasoning layer at certain steps.

## Pricing

- CrewAI: open-source framework + paid hosted offering.
- SynthBoard: $0 (Free) to $99/month (Ultra) for the full product, with API access on Ultra.
