- AG-UI (Open standard): Agent-User Interaction protocol for streaming agent state and events into frontend apps. Consider it because it does the same job with a different approach (open standard).
- A2A (Open standard): Agent2Agent, an open protocol for agents built on different frameworks to communicate and work together. Consider it because it also covers agent frameworks and SDKs.
- AutoGPT (Source-available + cloud): One of the first autonomous agent projects, now a platform for building, deploying and running continuous AI agents that automate workflows. Consider it because it also covers workflow automation; it has more GitHub stars (187,612 vs 38,064).
- Ruflo (Open source): Open-source multi-agent meta-harness for Claude Code, Codex, and MCP clients; Oct 13 release adds Mods (mission workflows) and a single control plane with human approval. Consider it because it also covers running many agents in parallel and workflow automation; it has more GitHub stars (74,609 vs 38,064).
- LangGraph (Open source): Framework for stateful, graph-based agent workflows. Consider it because it also covers workflow automation and agent frameworks and SDKs; it has more GitHub stars (43,237 vs 38,064).
- AstrBot (Open source): Open-source agent chatbot platform and framework that connects LLMs, plugins and tools to mainstream messaging apps for assistants, support bots and knowledge bases. Consider it because it also covers RAG and documents and agent frameworks and SDKs; it has more GitHub stars (42,095 vs 38,064).
- Orkes (Open source + cloud): Orchestration platform built on Conductor for durable workflows and AI agents. Consider it because it also covers workflow automation and multi-agent orchestration.
- OpenAI Agents SDK (Python) (Open source): OpenAI's Python SDK for building multi-agent workflows; v0.23.0/0.23.1 released Oct 1-2. Consider it because it also covers workflow automation and multi-agent orchestration.
- Haystack (Open source + cloud): Open-source orchestration framework for building production LLM apps, RAG and agents. Consider it because it also covers RAG and documents and multi-agent orchestration.
- Go Micro (Open source): Go framework for distributed systems where services double as tools for AI agents, with RPC, discovery, messaging and agent workflows. Consider it because it also covers workflow automation and agent frameworks and SDKs.
