Open Agent Builder

Open Agent Builder delivers a visual canvas for orchestrating AI agent workflows without writing Python scripts or managing complex codebases. The React Flow-powered drag-and-drop interface supports seven node types — Agent, Scraper, Transform, If/Else, Loop, User Approval, and MCP Tool — each configurable with provider-specific settings for Anthropic Claude (Haiku 4.5 and Sonnet 4.5), OpenAI GPT-5, Groq, or any OpenAI-compatible endpoint. The LangGraph orchestration engine handles state management, conditional routing, and human-in-the-loop approval gates while Firecrawl integration converts any website into structured, LLM-ready data through scrape, crawl, and map operations. E2B sandboxed code execution powers Transform nodes for secure data manipulation without risking host system integrity. Real-time streaming updates show execution progress node-by-node as workflows run, with Convex providing reactive database synchronization for workflow state and execution history. The TypeScript-first architecture (96.8% TypeScript) built on Next.js 16 App Router with Tailwind CSS delivers a responsive interface across devices. Clerk handles multi-user authentication with JWT integration for secure workspace isolation. Deploy via npm install and environment configuration with Firecrawl, Convex, and Clerk API keys. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Benefits

  • Multi-Provider AI Without Lock-In
  • Connect Anthropic Claude, OpenAI GPT-5, Groq, or any OpenAI-compatible endpoint in the same workflow. Switch providers per-node without rewriting prompts or pipelines.
  • Visual Canvas Replaces Code
  • Drag-and-drop React Flow interface eliminates Python scripting for agent orchestration. Seven configurable node types cover scraping, reasoning, branching, looping, and approval gates.
  • Native Web Scraping Integration
  • Built-in Firecrawl MCP tools convert any website into structured LLM-ready data through scrape, crawl, and map operations without separate extraction infrastructure.
  • Real-Time Streaming Execution
  • Watch workflows execute node-by-node with live streaming updates. Convex reactive database synchronizes execution state, enabling debugging and iteration without blind batch runs.

Features

  • React Flow Canvas
  • Drag-and-drop visual workflow builder with seven node types, connection handles, and real-time execution visualization powered by React Flow library.
  • LangGraph Orchestration
  • State management, conditional routing, parallel execution, and human-in-the-loop approval gates via LangGraph workflow engine with persistent state.
  • MCP Tool Integration
  • Native Model Context Protocol support for Firecrawl scraping tools, with extensibility for custom MCP servers and third-party tool providers.
  • Sandboxed Code Execution
  • E2B-powered Transform nodes execute arbitrary code in isolated cloud sandboxes, preventing data manipulation from affecting host system integrity.
  • Multi-LLM Support
  • Per-node provider selection across Anthropic Claude Haiku and Sonnet, OpenAI GPT-5, Groq fast inference, and OpenAI-compatible custom endpoints.
