Details

Manifest is a developer tool that converts webpages into structured JSON maps that AI agents can execute immediately.

To solve the fragile selector problem that existing browser automation tools have suffered from, it provides resolved CSS/Role locators that are not affected by changing DOMs. In particular, it supports dependencies between elements through a requires field that encodes actions that must precede pressing a specific button (e.g., activating a button after selecting a plan).

Key features include the following:

  • Support for REST API, Python SDK, LangChain integration
  • Includes an MCP (Model Context Protocol) server
  • Provides a webpage's clickable, input, and submittable elements as structured data
