index vs pinchtab
Browser automation for AI agents compared
index and pinchtab let AI agents work with websites through a browser. index is a Python agent that reasons through multi-step tasks and can return structured results, while pinchtab provides a Go server and CLI for controlling Chrome through an HTTP API.
index: Automate Complex Tasks in a Web Browser
Index is a Python browser agent that uses reasoning-capable language models to carry out multi-step web tasks and return structured results. It offers a CLI, a Python interface, and a serverless API, but the repository is archived.
pinchtab: Control Chrome for AI Agents
PinchTab is a local-first Go server and CLI that lets AI agents control Chrome through an HTTP API. It supports token-efficient page interaction, persistent profiles, and multiple browser instances.

Key differences
- index uses Python and provides an agent interface, an interactive CLI, and a serverless API; pinchtab uses Go and provides a local HTTP server, CLI, and MCP server.
- index focuses on model-driven browser tasks, including research and structured data extraction; pinchtab focuses on Chrome control, page inspection, and interaction through browser tools.
- index supports structured results with Pydantic schemas and can use a personal Chrome session; pinchtab supports persistent, isolated profiles and multiple browser instances.
- index offers a managed serverless API; pinchtab is local-first, with remote setups requiring operators to secure its privileged control interfaces.
- index is archived and uses an Apache-2.0 license; pinchtab is not archived and uses an MIT license.
- index is written in Python; pinchtab is written in Go and can be packaged as a standalone binary, with Chrome or Chromium installed separately.
