About The Project

OpenAgent is a full-stack platform for teams building AI applications rather than a single chat demo. The repository combines a Flask backend, Celery workers, a Vue 3 frontend, visual workflow authoring, dataset and document management, public app and workflow publishing, and OpenAPI-based delivery.

What the current codebase already supports:

• Use the home assistant to route user requests to published public agents through A2A, or turn natural-language requirements into new AI app creation flows.
• Build and manage AI apps from a dedicated workspace with draft, publish, analysis, version comparison, and prompt comparison flows.
• Design workflows visually with nodes for LLMs, tool calls, dataset retrieval, code execution, HTTP requests, branching, text processing, template transforms, and structured parameter extraction.
• Manage datasets, upload documents, inspect segments, and connect retrieval to agents and workflows.
• Browse public apps, tools, and workflows through store-style views.
• Expose published apps over REST and SSE through POST /api/openapi/chat.

Getting Started

Prerequisites

• Docker 20.10+
• Docker Compose 2.x
• 8 GB+ RAM recommended for the full stack
• Access to at least one supported model provider API key

Installation

1. Clone the repository.

   git clone https://github.com/Haohao-end/openagent.git
   cd openagent

2. Create the runtime environment file.

   cp api/.env.example api/.env

3. Review the minimum required settings in api/.env.

   • JWT_SECRET_KEY
   • POSTGRES_PASSWORD
   • REDIS_PASSWORD
   • WEAVIATE_API_KEY
   • VITE_API_PREFIX
   • At least one provider key such as OPENAI_API_KEY, ATLASCLOUD_API_KEY, DEEPSEEK_API_KEY, or DASHSCOPE_API_KEY

4. Start the Docker stack.

   cd docker
   docker compose up -d --build

5. Open the local services.

   Service	URL	Notes
   Frontend	http://localhost:3000	Vue 3 web UI
   API	http://localhost:5001	Flask REST API
   Nginx	http://localhost	Reverse proxy

Local Development

Backend:

cd api
pip install -r requirements.txt
flask run --port 5001

Frontend:

cd ui
npm install
npm run serve

Vite serves the frontend on port 5173 by default. The frontend configuration resolves the API base from VITE_API_PREFIX, and local development commonly proxies /api to the Flask backend.

Useful commands:

cd api
pytest

cd ui
npm run type-check
npm run lint
npm run build
npm run test:unit -- --run

Usage

1. Home Assistant Experience

Use the home page as the default assistant entry point to route user questions to the most relevant published public agents through A2A, or describe a new idea in natural language and trigger AI app creation. The same surface also supports multi-turn chat, suggested prompts, image upload, and audio input.

2. App Workspace and Deep Research

The app workspace is the main work area for an AI app, not a standalone settings page. The left side handles model, prompt, and capability bindings. The right side is used for live debugging, execution traces, and result checks. In the current codebase, the README term Deep Research maps to the deep thinking mode behind enable_deep_thinking.

Key capabilities:

• Configuration and version management: manage model changes, prompt logic, drafts, publishing, version comparison, prompt comparison, and app duplication in one place.
• Capability integration: bind plugins, MCP, Skills, child Agent apps, workflows, and datasets through a single workspace.
• Complex task execution: with Deep Research enabled, the app can break work into steps and coordinate bound capabilities across a longer execution chain.
• Sandbox and artifact output: support script execution, code handling, file generation, and attachment export for tasks that need concrete outputs.
• Debugging and result verification: use the right-side panel to run real conversations and inspect deep execution timelines, task state, produced artifacts, and final results.

3. Visual Workflow Editor

Author workflows with nodes such as LLM, tool, dataset retrieval, code, HTTP request, template transform, text processor, variable assigner, parameter extractor, if/else, start, and end.

4. Dataset and Retrieval

Create datasets, upload documents, inspect segments, and wire retrieval nodes into workflows or AI apps for knowledge-enabled behavior.

5. OpenAPI Delivery

Publish an app and call it over POST /api/openapi/chat with standard or streaming responses, including support for multi-turn conversation identifiers.
