What is BabelWrap?

BabelWrap is a lightweight HTTP API and MCP server that lets AI agents interact with any website — navigate, read, click, fill forms, submit, and extract data — without spinning up a full browser stack.

Your agents think in actions, not DOM selectors. Instead of writing fragile CSS selectors or XPath expressions, agents describe what they want in plain English: "click the Login button", "fill the email field", "extract all product prices."

BabelWrap translates these natural-language instructions into real browser interactions and returns a structured, LLM-readable snapshot of the page after every action.

How is BabelWrap different?

The Snapshot Format

Every action returns a structured snapshot that an LLM can immediately understand and reason about. This is BabelWrap's core innovation.

Text representation (what an agent sees):

URL: https://example.com/login
TITLE: Sign In -- Example

CONTENT:
  Welcome back. Sign in to continue.

INPUTS:
  [email-field] Email address (text, empty)
  [password-field] Password (password, empty)
  [remember-me] Remember me (checkbox, unchecked)

ACTIONS:
  [sign-in-btn] Sign In (button, primary)
  [forgot-password] Forgot password? (link -> /reset)
  [create-account] Create account (link -> /signup)

NAVIGATION:
  Home | Products | Pricing | Blog | Docs

ALERTS:
  (none)

The snapshot includes:

• url / title — current page location and document title
• content — main readable text on the page (up to 15,000 characters)
• inputs — all form fields with their current values
• actions — all clickable elements (buttons, links)
• navigation — site navigation links
• alerts — any visible error messages, success banners, or warnings
• forms — logical groupings of fields and their submit buttons
• tables — structured table data with headers and rows
• lists — ordered and unordered list items
• frames — inputs and actions detected inside same-origin iframes

For the full JSON format and field reference, see The Snapshot Format.

Pricing

That's $10 per 1,000 actions. No monthly subscription, no commitment — you pay only for what you use. Free tier resets on the first of each month.

Site Mapping: $10 per site to generate typed tools your agent can call directly (e.g., linkedin_search_jobs). Charged only if mapping succeeds. Pre-mapped sites from the public catalog are free to use. Full pricing details →
