agentUniverse and ii-agent
Both are open-source frameworks for building and deploying intelligent multi-agent applications, making them direct competitors in the lightweight agent framework category.
About agentUniverse
agentuniverse-ai/agentUniverse
agentUniverse is a LLM multi-agent framework that allows developers to easily build multi-agent applications.
Provides pre-built multi-agent collaboration patterns (PEER for iterative reasoning, DOE for data-intensive tasks) tested in real financial scenarios, enabling domain-expert-level agents without building orchestration from scratch. Supports 10+ LLM vendors via simple configuration—Qwen, DeepSeek, OpenAI, Claude, Gemini, and others—making it agnostic to model choice. Includes extensible components for tools, knowledge bases, and RAG integration alongside a visual workflow platform for agent application design.
About ii-agent
Intelligent-Internet/ii-agent
II-Agent: a new open-source framework to build and deploy intelligent agents
Supports autonomous full-stack development, presentation generation, and deep research tasks through multi-model orchestration and tool integration. The framework enables switching between LLMs (Gemini, Claude, GPT) within a single conversation thread while leveraging specialized capabilities like code interpretation and file search. Designed for complex, multi-step workflows that combine reasoning, code generation, and information synthesis across integrated research and development modules.
