CrewAI is an MIT-licensed Python framework, started in October 2023, for building multi-agent systems from role-based Crews and event-driven Flows. It supports MCP servers and agent-to-agent (A2A) collaboration, and its CrewAI AMP platform adds a visual editor, tracing, guardrails and governance for production use.
About CrewAI
CrewAI is an open-source Python framework for building teams of AI agents, plus a commercial platform called CrewAI AMP for building, running and governing them. Founder and CEO João Moura, who previously directed AI engineering at Clearbit, created the GitHub repository in October 2023, and the company launched in January 2024. In October 2024 it announced $18M in total funding, with boldstart ventures leading an inception round and Insight Partners leading the Series A. The framework is released under the MIT licence, and TechCrunch described the company as based in San Francisco and Brazil.
The framework has two building blocks. A Crew is a group of agents, each described by a role, goal and backstory, that work through tasks together. A Flow is an event-driven workflow that holds state and can run crews as steps, which gives a team explicit control around otherwise autonomous agents. Agents attach tools, knowledge sources, memory and planning, and can use MCP servers as tools or collaborate over the A2A protocol. On the model side, the docs describe native integrations for OpenAI, Anthropic, Google, Microsoft Azure and Amazon Web Services Bedrock, with LiteLLM as a fallback for everything else, and they name GPT-4o mini as the default model until you set another.
CrewAI AMP is the managed side. It adds Studio, a visual editor with an AI copilot, plus tracing, guardrails, human-in-the-loop input and a usage dashboard, and the Enterprise plan adds single sign-on, role-based access control and deployment in a customer's own VPC. In the AI orchestration category, the closest alternatives are LangChain for a mature, widely adopted framework with the LangSmith observability product, Mastra for TypeScript teams, and n8n for workflow automation where AI is one step among many. Business users who want an assistant without code are better served by Lindy. For a wider buying frame, read Best AI Orchestration Tools in 2026 and Best AI Agent Builders in 2026. Because CrewAI ships its own tracing, the guide on the three jobs inside agent observability helps decide whether that is enough, and the agents and automation group lists the neighbouring categories.
Security and privacy need a deliberate look before a production rollout. Reviewers should request the SOC 2 attestation the vendor publishes, and should know the framework sends anonymous usage telemetry unless it is switched off. Peers with a published SOC 2 claim sit in the SOC 2 facet, and other open-source tools are grouped in the open-source facet.
Pricing
The open-source framework is MIT-licensed and free to self-host, and LLM usage is a separate bill from whichever provider you choose. On the hosted AMP platform, the entry plan costs nothing and the top plan is quoted per customer, so ask for written terms on included executions and overage. By contrast, LangChain publishes per-seat plans for its LangSmith product, while n8n lists cloud tiers on its site.

| Tier | Monthly price | What it includes |
|---|---|---|
| Open source framework | Free | MIT licence, Crews and Flows, MCP and A2A support, Memory and checkpointing, Self-hosted, LLM costs paid to your provider |
| AMP Basic | Free | Studio visual editor and AI copilot, GitHub integration, 50 workflow executions per month, Tracing and guardrails, Community support |
| AMP Enterprise | Custom | SSO and role-based access control, CrewAI cloud, customer VPC or customer infrastructure, Enterprise connectors, Dedicated support, 45-day onboarding |
Key Features
- Crews: Teams of agents defined by role, goal and backstory in YAML, code or both, with optional memory, reasoning, tools and sandbox environments.
- Flows: Event-driven workflows that hold state and run crews as steps, so execution order stays under the developer's control.
- Tools and MCP: Hundreds of open-source tools out of the box, MCP servers as tools over stdio, SSE or streamable HTTP, and sandbox tools for E2B and Daytona.
- Model connections: Native SDK integrations for OpenAI, Anthropic, Google Gemini, Azure and AWS Bedrock, with LiteLLM as the fallback for other providers.
- Memory and knowledge: A memory system the vendor describes as remembering, resolving contradictions and forgetting on purpose, plus knowledge sources agents can query.
- Checkpointing: Captures runtime state at every step so a run can be replayed from a chosen step, forked, or rerun with different inputs.
- Agent-to-agent protocol: Connects crews over the A2A protocol, with native async support and streaming results from flows and crews.
- Studio and tracing: A visual editor with an AI copilot, tracing, OpenTelemetry, guardrails, human-in-the-loop input and a usage dashboard on the cloud platform.
Pros
- The framework is MIT-licensed, and its GitHub repository shows about 59.6K stars and 8.7K forks (read 2026-10-13), which lowers lock-in risk for a self-hosted build.
- The trust center lists a SOC 2 Type 2 report dated June 2026 and a HIPAA audit report from February 2026, which gives security reviewers documents to request.
- Switching telemetry off takes one environment variable, and the docs list every field collected by default.
- G2 lists a 4.3 out of 5 average from 26 reviews (read 2026-10-13), although the profile is unclaimed and the sample is small.
Cons
- Anonymous telemetry is on by default and collects tool names and agent roles, and when share_crew is enabled it also collects task descriptions and backstories that may contain personal data.
- The docs name gpt-4o-mini as the default model, and the OpenAI SDK is a core dependency, so an OpenAI key is the path of least resistance unless you configure another provider.
- The current release needs Python 3.10 to 3.13, and the docs carry a migration section and a guide to running without LiteLLM, so pin versions and read the changelog before upgrading.
- Enterprise pricing is not published, and the pricing page describes a 45-day onboarding with forward deployed engineering and training sold a la carte.
Data Handling
- Training-data policy
- TechCrunch reported in October 2024 that the company does not train its own models and uses models from providers such as OpenAI and Anthropic.
- Compliance
- SOC 2 Type 2 (vendor trust center lists a June 2026 report); HIPAA audit report listed (February 2026)
Frequently Asked Questions
What are CrewAI's pricing plans in 2026?
CrewAI has three routes. The open-source framework carries no licence fee, and your model provider bills the LLM calls and your host bills the compute. The cloud platform has a free Basic plan, while Enterprise is custom-priced with no public figure, sized to the workflow and billed with flexible overage. Ask an Enterprise quote to state included executions, overage rates and whether onboarding is part of the price.
Can you use CrewAI without paying?
Yes, in two ways. The framework itself is free under the MIT licence, and the Basic cloud plan includes the visual editor, AI copilot and GitHub integration, capped at 50 workflow executions a month with community support only. SSO, role-based access control and VPC deployment are Enterprise features, so a team that needs them will leave the free plan. Free use still costs money in model calls.
Which tools compete with CrewAI in 2026?
Start with [LangChain](/hub/tools/langchain) if you want a mature, widely adopted framework with LangSmith for tracing and evaluation. [Mastra](/hub/tools/mastra) is the TypeScript route, for teams that do not write Python. Choose [n8n](/hub/tools/n8n) if the workflow is mostly connecting apps with a few AI steps, and [Lindy](/hub/tools/lindy) if business users rather than engineers will build the agents.
Is CrewAI better than LangChain?
Neither wins outright. CrewAI is organised around role-based crews and event-driven flows, and sells a governed platform on top of the framework. LangChain is a general agent framework paired with LangSmith, which has public per-seat plans. Choose CrewAI when your design is cooperating role-based agents, and LangChain when you want LangSmith's evaluation workflow around your agents.
How do you set up CrewAI?
Install the Python package, set an API key for your model provider, and build a first Flow from the quickstart, which combines orchestration, state and an agent crew. For the cloud route, sign up for the Basic plan and use Studio with the AI copilot. Disable telemetry with CREWAI_DISABLE_TELEMETRY before running anything that touches sensitive text.
Top Alternatives
