Index is an open-source browser agent that autonomously performs complex tasks on the web by turning any website into an accessible API. It is powered by vision-capable reasoning LLMs like Gemini 2.5 Pro, Claude 3.7 Sonnet, and OpenAI o4-mini, and can be used as a Python library, CLI, or serverless API.
Use cases
- automate multi-step tasks on websites from a natural language prompt
- extract structured data from web pages into pydantic schemas
- scrape and summarize content from sites without a public API
- fill out forms and interact with web apps programmatically
- run an interactive CLI agent to browse the web for me
- turn any website into an API for my application
When to choose
- you need an autonomous agent to complete complex multi-step web tasks
- you want structured data extraction from websites with vision-capable LLMs
- you prefer an open-source alternative to closed browser agents
- you want observability and tracing of agent browser sessions
When to avoid
- you need simple static HTML scraping without LLM reasoning overhead
- you cannot share page content with third-party LLM APIs due to privacy constraints
- you need guaranteed deterministic automation for stable workflows
