Open-source Java framework for building AI agents and LLM apps
Configure any supported provider with an API key and model name, then call chat() for a consistent interface across models.
AgentRunner combines policy and middleware to coordinate models, tools and sandboxes inside a single execution flow.
Reusable, versionable capability definitions that bundle a SKILL.md, scripts and assets, discovered from local directories or remote storage.
Add knowledge retrieval, image generation and OCR pipelines on demand, mixing synchronous and asynchronous execution styles.

Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

#1Free / Open-sourceAn open-source automation powerhouse with deep app connectors, though less specialized for native LLM prompt chaining.

Give your AI agents secure, authenticated access to 1,700+ apps
Offers a streamlined no-code builder for deploying custom AI agents, but lacks Dify's open-source flexibility.

Web search API and crawler built for AI agents

Free / Open-sourceA self-hosted chat interface for running local LLMs, though lighter on complex visual workflow orchestration.

SpecialistProvides advanced programmatic frameworks for document parsing and RAG pipelines, but requires coding instead of visual canvases.

Baidu's one-stop platform for building, distributing and monetizing AI agents

Free / Open-sourceThe TypeScript framework for building, deploying, and observing AI agents
The managed vector database and knowledge engine for production AI
Free / Open-sourceAn open-source automation platform combining visual flows with AI steps, though geared more towards general app integration.

Built for scaling multi-agent workforces and B2B task automation, though less focused on open-source RAG pipelines.
