What do you like best about crewAI?The best part about crewAI is that while building an agent we can provide the role, goal and backstory for the agent which increases the performance of that agent very much. Its supports all the LLM providers like OpenAI, Groq, Nvidia Nemo etc. The documentation is very clean and easy to understand. It supports many tools and MCP servers which we can use to build the Multi-Agent systems. Review collected by and hosted on G2.com.What do you dislike about crewAI?Budling very complex Agentic Flows requires very much of trail and error. Review collected by and hosted on G2.com.
What do you like best about crewAI?crewAI stands out for its innovative approach to agent orchestration. I love how easy it is to define specialized agents with unique roles and responsibilities, then have them collaborate in a structured workflow. The flexibility to plug in different LLMs, customize tools per agent, and define dynamic tasks through crew structure gives it a lot of power and adaptability. It's great for building multi-agent systems without needing to start from scratch. Review collected by and hosted on G2.com.What do you dislike about crewAI?While powerful, crewAI can feel a bit overwhelming for newcomers. The documentation could be more beginner-friendly, especially for users not deeply familiar with multi-agent systems or LLM architectures. Setting up complex flows requires some trial and error, and real-time debugging support could be improved. Review collected by and hosted on G2.com.
What do you like best about crewAI?What I like best about crewAI is how quickly it helps me move from idea to execution. In tech, there’s always too much to do and not enough time, and crewAI feels like having an extra teammate who’s always available and doesn’t mind doing the repetitive or tedious stuff. I especially like how it can coordinate tasks across different tools and workflows...it’s not just another AI chatbot, it’s more like an operations partner. The UI is straightforward, and it doesn’t take forever to figure out how to get things done. Overall, it’s freed me up to focus on higher-level problem solving instead of chasing down little details all day. Review collected by and hosted on G2.com.What do you dislike about crewAI?What I dislike is that sometimes crewAI feels a bit too eager to help...like it’ll jump in with suggestions before I’ve fully clarified what I want. It’s not a dealbreaker, but it can mean extra back-and-forth to get the exact output I’m looking for. Also, integrations are good, but I wish there were more native ones with some of the niche tools I use at work. Feels like that would make it even more seamless.

What do you like best about LlamaIndex?As a data scientist dealing with large language models LLMs I found LlamaIndex quite helpful to manage. It has granted me the ability to input data in formats such as PDFs or API, databases and excel, which makes it easier for me to train and execute LLMs with numerous datasets. Review collected by and hosted on G2.com.What do you dislike about LlamaIndex?This is where the perceived level of control over natural language processing (NLP) in the platform is somewhat constrained. Specific to pipeline needs or how the language model is resolved, there is less fine-grained control than directly coding within the LLM context provided by LlamaIndex.
