- LlamaIndex (Open source + cloud): Framework for agents over your data (RAG, document agents). Consider it because it also covers agent frameworks and SDKs.
- 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 agent frameworks and SDKs.
- Haystack (Open source + cloud): Open-source orchestration framework for building production LLM apps, RAG and agents. Consider it because it also covers multi-agent orchestration and agent frameworks and SDKs.
- DocETL (Open source): System for agentic, LLM-powered document processing and ETL pipelines from UC Berkeley. Consider it because it does the same job with a different approach (open source).
- Langchain.rb (Open source): Ruby library for building LLM-powered applications, RAG and assistants. Consider it because it also covers agent frameworks and SDKs.
- BaseAI (See site): Web AI framework from Langbase for building AI agents with memory (RAG) and deploying them serverless. Consider it because it also covers memory and agent frameworks and SDKs.
- Sage (Open source): Sage is an MIT-licensed framework for building configurable, self-improving AI agents from reusable agent packages, tools, Skills and MCP services. It supports multi-agent workflows and multi-round self-improvement, keeping a version history of agent packages so you choose which version to adopt. Consider it because it also covers workflow automation and multi-agent orchestration.
- Dynamiq (Open source): Python orchestration framework for building agentic and RAG applications from reusable nodes and workflows. Consider it because it also covers workflow automation and multi-agent orchestration.
- Mastra (Open source): TypeScript framework for agents, workflows and RAG. Consider it because it also covers workflow automation and agent frameworks and SDKs.
- DeepSeek Harness (Open source): DeepSeek's open-source agent harness with a local web UI, built so that every tool, model and scheduled task is a swappable plugin; still a developer preview. Consider it because it also covers agent frameworks and SDKs; it has more GitHub stars (251,853 vs 57,594).
