Turn any code snippet into an interactive flowchart you can actually read
Paste a snippet in Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, and others to get an interactive diagram of its logic.
Generate flowcharts, sequence diagrams, class diagrams, and user-journey views depending on what you need to explain.
A written explanation accompanies each diagram so you can verify the AI's reading of the logic against your own.
Download results as PNG, SVG, or PDF, or share a link to the diagram with teammates and reviewers.

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.

#1Offers a streamlined no-code builder for deploying custom AI agents, but lacks Dify's open-source flexibility.

Free / Open-sourceA self-hosted chat interface for running local LLMs, though lighter on complex visual workflow orchestration.
#3AI diagrams and technical design docs built from your code and systems

AI diagramming, mind mapping and project tools with 50,000+ templates


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

Free / Open-sourceAn open-source automation platform combining visual flows with AI steps, though geared more towards general app integration.

AI-powered visual collaboration for diagrams, mind maps, and charts

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

Focuses on visual drag-and-drop orchestration for building chatbots and autonomous agents without writing code.

Provides an all-in-one visual workspace for building custom AI agents and publishing them to messaging platforms.
