What is it?

WebRover is an AI web agent that takes a natural-language request, decides whether it is a browsing task or a research question, and carries it out by interacting with web pages. It is built with Python and FastAPI on the backend, LangGraph for agent state management, and Playwright for browser automation, with a Next.js and TypeScript chat interface on the frontend.

The project offers three agent types: a Task Agent that plans and executes multi-step actions on websites, a Research Agent that gathers and summarizes information from sources, and a Deep Research Agent that breaks a topic into subtopics and produces a structured paper with citations. A vector store and RAG pipeline support retaining and retrieving collected information. Supported LLMs include GPT-4o, o3-mini and Claude 3.5 Sonnet.

The browser runs locally under the user's control, and results can be returned in chat, downloaded as PDF, or exported to Google Docs.

Key features

  • 01Three agent types for task automation, research, and deep research
  • 02Local browser control via Playwright with multi-tab management
  • 03Streaming of agent actions and reasoning in a chat interface
  • 04RAG pipeline with a vector store for retaining collected information
  • 05Export of results to PDF, Google Docs, or clipboard

Use cases

  • Automating repetitive multi-step tasks on websites
  • Gathering and summarizing information from multiple web sources
  • Drafting research papers with citations on a given topic

Quick start

  1. 1

    Clone the repository and enter the backend folder

    git clone https://github.com/hrithikkoduri18/WebRover.git
  2. 2

    Install dependencies with Poetry (after setting Python 3.12 and running poetry install)

    poetry install
  3. 3

    Start the backend API server on port 8000

    uvicorn app.main:app --reload --port 8000
  4. 4

    Install frontend dependencies and run the frontend dev server (in the frontend folder)

    npm install

Things to know

  • Requires an OpenAI or Anthropic API key to run the LLM-based agents.
  • Setup is multi-step, needing Poetry, Python 3.12, and a separate Next.js frontend.
  • Some Mac users may hit browser connection issues that need manual workarounds.
