2. LangGraph

LangGraph focuses on building more controllable and stateful agent workflows. Instead of treating an agent as a simple sequence of prompts, developers can represent an application as a graph of interacting steps. This can be helpful when an AI workflow requires persistence, branching logic, multiple agents, or human intervention. For complex enterprise applications, explicit workflow control can make testing and debugging easier.

Key features:

• Stateful agent workflows
• Multi-step orchestration
• Human-in-the-loop patterns
• Persistence
• Agent coordination
• Workflow control

3. CrewAI

CrewAI takes a role-based approach to multi-agent development. Developers can create different agents with defined responsibilities and allow them to work together on a broader task. For example, one agent could conduct research while another analyzes the information and another prepares an output. This approach can be useful for business workflows where tasks naturally divide into specialized roles.

Key features:

• Multi-agent systems
• Role-based agents
• Task delegation
• Agent collaboration
• Workflow automation

4. Microsoft AutoGen

Microsoft AutoGen is designed for building applications involving AI agents that communicate and collaborate.

Its enterprise-oriented ecosystem can also make it relevant to organizations already working extensively with Microsoft technologies.

Key features:

• Multi-agent conversations
• Agent orchestration
• Tool integration
• Human interaction
• AI workflow development

5. LlamaIndex

LlamaIndex focuses strongly on connecting AI applications and agents with external and private data. This makes it particularly relevant when an organization wants an AI assistant that can work with internal documents, databases, knowledge bases, or other information sources. For example, an organization could build an internal knowledge assistant that retrieves relevant company information before generating an answer.

Key features:

• Retrieval-Augmented Generation (RAG)
• Data connectors
• Knowledge retrieval
• Document processing
• Data-connected agents

6. Semantic Kernel

Semantic Kernel is Microsoft's open-source SDK for integrating AI capabilities into applications. It provides developers with ways to combine AI models, plugins, functions, and application logic. For organizations that already have established enterprise software systems, this type of integration can be important because an AI agent often needs to interact with existing business applications rather than operate independently.

Key features:

• AI orchestration
• Plugins and functions
• Enterprise application integration
• AI service integration
• Agent development capabilities

7. Haystack

Haystack is an open-source framework focused on building AI applications around search, retrieval, question answering, and generative AI. Its pipeline-based approach can be useful when developers need to combine retrieval, document processing, LLMs, and agent functionality. It is particularly relevant for applications where accurate access to business information is a major requirement.

Key features:

• RAG pipelines
• Document processing
• Search
• Knowledge retrieval
• AI agents
• Pipeline orchestration

8. OpenAI Agents SDK

The OpenAI Agents SDK provides developers with building blocks for creating applications in which agents can use tools, hand off tasks, and coordinate application behavior. This can be useful for applications where an AI agent needs to move beyond conversation and interact with external functionality. Developers can design workflows in which different agents or tools handle specific parts of a broader user request.

Key features:

• Agent workflows
• Tool use
• Agent handoffs
• Orchestration
• Application development
