CrewAI vs AutoGen (2025): Which AI Agent Tool Is Right for You?

In 2025, AI is no longer just about chatting with a smart assistant. Today, you can build a whole team of AI agents that work together to do complex tasks—just like a real team of humans. Tools like CrewAI and AutoGen make this possible.

These platforms help developers, startups, and even non-tech users set up smart “virtual teams” where different AI agents take on specific roles—like researcher, planner, or coder—and collaborate to complete a job.

In this blog, we’ll keep things simple. You’ll learn:

• What CrewAI and AutoGen are

• How they work in 2025

• The key differences between them

• Which one might be the better fit for you

What Is CrewAI?

CrewAI is an open-source tool that lets you create a group (or "crew") of AI agents. Each agent in the crew has a job—like answering questions, searching the web, or writing a report.

CrewAI is known for:

• Being beginner-friendly

• Having lots of built-in tools

• Handling many things automatically so users don’t have to write complex code

For example, if you want to build an AI system that researches a topic and then writes a summary, CrewAI can help set up agents that work together to do that.

💡 Best for: People who want an easy start with AI agents and ready-to-use features.

What Is AutoGen?

AutoGen, created by Microsoft, is another open-source framework for building AI agent systems. Instead of setting up agents with job titles, AutoGen builds AI agents that talk to each other—like a group chat between smart bots.

AutoGen is powerful, but it takes more work to set up. You need to build the rules for how agents talk and what they do. It’s more flexible, but not as easy to use.

In 2025, Microsoft moved AutoGen into maintenance mode—this means it will still work, but no big new features will be added. Microsoft is now focusing on a new project called Agent Framework.

💡 Best for: Advanced users or teams that need custom AI workflows and are comfortable with more setup.

Here’s a side-by-side look at how the two tools compare:

Feature	CrewAI	AutoGen
Who made it	Independent developer (João Moura)	Microsoft
Style	Role-based AI teams	Chat-based AI conversations
Ease of use	Beginner-friendly	For experienced users
Built-in tools	Lots—search, file reading, summaries, etc.	Some built-in features, more manual setup
Customization	Limited (but fast to start)	High (but requires more effort)
2025 status	Actively updated	Maintenance only (no big updates coming)
Best for	Quick setup and small to mid-size projects	Advanced, custom, enterprise-level projects

What’s New in 2025?

As of late 2025:

• CrewAI is growing fast with regular updates. New tools and smarter planning features have been added.

• AutoGen is still supported, but Microsoft is focusing on something new. If you're starting fresh, Microsoft suggests checking out their new Agent Framework.

Final Thoughts: Which One Should You Choose?

If you’re just starting out, or if you want something that works quickly with less setup, CrewAI is a great choice in 2025. It’s simple, powerful, and still growing fast.

If you need total control, or if you’re building large, complex systems and have technical experience, AutoGen might still be worth using—just keep in mind it’s no longer getting major updates.

For many users, CrewAI is now the go-to option for setting up smart, multi-agent AI systems without too much hassle.
