A node-based visual AI workflow and LLM Agent builder with local model support and multimodal orchestration across desktop, web, CLI, and mobile.
NodeTool is a local-first, node-based visual platform for building AI workflows and LLM Agents. It features a drag-and-drop node editor with 100+ built-in node types and tools, supporting unified processing of text, image, video, and audio.
Core Capabilities
- Visual Workflow Engine: Drag-and-drop node editor with type-safe connections, async execution engine with per-node real-time preview, exportable as interactive Mini-Apps
- AI Agent System: Built-in Agent framework with task planning and tool calling, 100+ built-in tools, interactive Agent chat mode in CLI
- Model Integration: Local models (Ollama, MLX, GGUF/GGML) for fully offline operation; cloud providers (OpenAI, Anthropic, Gemini, Replicate, FAL, ElevenLabs, HuggingFace) via BYOK
- RAG & Knowledge Management: Built-in document indexing and semantic search using SQLite-vec vector database with zero external dependencies
- Multimodal Processing: Text generation, image generation/transformation (FLUX, NanoBanana), video processing, speech transcription and synthesis
- Extensions & Sandboxing: TypeScript custom nodes (node-sdk BaseNode), Python custom nodes (PythonStdioBridge lazy-loading worker), Docker-isolated code execution sandbox
Product Forms
- NodeTool Studio: Local desktop app with local model support, data never leaves the machine
- NodeTool Cloud: Hosted version, browser-accessible, no installation or GPU required
- Both share the same open-source codebase with seamless workflow portability
Architecture
TypeScript monorepo managed by Turborepo (28 backend packages). Key packages: kernel (DAG orchestration), node-sdk (BaseNode class & node registry), agents (task planning & tools), runtime (processing context & LLM providers), websocket (HTTP + WebSocket dual-protocol server), vectorstore (SQLite-vec), code-runners (Docker sandbox). Frontend: React + Vite + MUI + React Flow. Desktop: Electron 39 (embedded Node 24). Mobile: React Native + Expo. Runtime: Node.js 24+ (native async), Python 3.11 optional. Testing: Vitest + Playwright.
