CrewAI

What it does

CrewAI is an open-source Python framework for building systems of AI agents that collaborate on a task, each with its own role, goal, and set of tools. Rather than a single agent handling everything, a developer defines a “crew” — for example a researcher, a writer, and a reviewer — and CrewAI orchestrates how they work together, either through autonomous “Crew” collaboration or more tightly controlled, event-driven “Flows.” Because it’s code-first and self-hostable, it’s aimed squarely at developers and engineering teams rather than business users looking for a no-code builder.

A managed cloud platform (CrewAI Enterprise/Cloud) sits on top of the free open-source core for teams that want hosted deployment, monitoring, and governance without running their own infrastructure. As with most agent frameworks, LLM API costs from whichever provider you connect are separate from and typically larger than CrewAI’s own platform fees, so the “free” open-source label understates the real cost of running agents at scale.

Ideal users

• Developers and engineering teams who want to build custom multi-agent systems in code rather than a no-code interface
• Companies that need agents to collaborate on a task — for example a research agent, a writer agent, and a reviewer agent — with defined roles
• Teams that want the option to self-host an open-source framework and only pay for a managed cloud layer if they need it
• Technical teams evaluating agent frameworks for production deployment, not just prototyping

Who should avoid it

• You want a no-code way to build agents — better served by Relevance AI or Microsoft Copilot Studio
• You want a ready-to-use consumer agent you can prompt without writing any code — better served by Manus
• You need a fully managed, vendor-hosted enterprise platform with built-in CRM or Microsoft 365 integration — better served by Agentforce or Copilot Studio
• Your team has no engineering resources to build, deploy, and maintain agent code

Key features

• Open-source Python framework (MIT license) for orchestrating multiple autonomous agents
• 'Crews' for autonomous agent collaboration and 'Flows' for precise, event-driven control
• A large library of built-in tools for web search, website interaction, vector database queries, and code execution
• Role-based agent design — assign each agent a role, goal, and set of tools
• A managed cloud platform (CrewAI Enterprise/Cloud) for deployment, monitoring, and management on top of the open-source core
• A large learning ecosystem, including community courses and certifications, for teams ramping up

Pricing

Free — Free (Basic tier); custom pricing for Enterprise

Confirmed via crewai.com/pricing (mid-2026): the platform currently lists only two tiers. The Free/Basic tier includes the visual editor, AI copilot, GitHub integration, and 50 workflow executions/month. Enterprise adds CrewAI-hosted or private infrastructure, SSO, a dedicated VPC, a FedRAMP High compliance option, and 50 hours/month of development support, priced individually per customer rather than published.

Typical workflows

• A development team defines a 'crew' of agents — one to research a topic, one to draft a report, one to review it — and runs the crew end-to-end from a script or scheduled job.
• An engineering team uses CrewAI Flows to combine deterministic, event-driven steps with autonomous agent reasoning for the parts of a pipeline that need judgment.

Integrations

• Custom tool integrations via Python, including web search, vector databases, and code execution
• Connects to major LLM providers such as OpenAI and Anthropic via API keys

Privacy & security notes

Because the open-source framework runs on your own infrastructure and API keys, data handling depends largely on which LLM provider and hosting you choose. For the managed Cloud/Enterprise platform, CrewAI's privacy policy states customer and Google-account data is never used to train AI models; account data is deleted or anonymized within 30 days of account deactivation, with disaster-recovery backups retained for up to 180 days.
