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.

Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.

#1SpecialistOpen-source workflow automation built for AI agents and technical teams
SpecialistA free, open-source personal AI agent that learns your projects and works across every messaging app.
#3
SpecialistOpen-source personal AI assistant that runs on your own machine and works from chat apps
Offers a streamlined no-code builder for deploying custom AI agents, but lacks Dify's open-source flexibility.

Free / Open-sourceFocuses on collaborative team AI workspaces and plugins, but shares similar open-source architectural goals.
SpecialistFocuses heavily on privacy-first document chat and local RAG pipelines, but offers fewer general-purpose chat UI features.

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


Free / Open-sourceOffers robust multi-provider support and advanced user permission management, but has a slightly different configuration setup.
Free / Open-sourceDelivers a desktop-native application for running local models offline easily, but lacks Open WebUI's server-centric multi-user features.
SpecialistOpen-source AI automation that unifies agents, flows and 770+ app integrations

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