About
fab is a CLI that lets AI agents browse, sign in, fill forms and scrape the web from plain English instructions, returning JSON output. The project claims it is faster, cheaper and more accurate than pairing an LLM with chrome-devtools-mcp. The repository is dual licensed under Apache-2.0 and MIT.
At a glance
fab takes a plain-language browser task and can return structured records. It is worth evaluating for extraction where an agent would otherwise have to inspect each page and assemble the result itself.
Good fit
Agent builders automating repetitive reads from a test site or public pages with a stable structure.
Consider something else when
Use explicit scripted steps when every action must be deterministic or a mistaken click would have consequences.
Start here
On a public page, ask for two or three known records with a schema for the fields you need. Compare the returned values and omissions with the page.
Cost and requirements
The project documents a CLI and browser workflow. Account for model usage when comparing the cost of repeated tasks.
Limits to know
Test record completeness yourself. A response can match the requested shape and still omit an item or extract the wrong value.
