Manifest (omfang): Pricing, Features & Best Use Cases

API that turns any URL into a structured JSON map of the actions an AI browser agent can take on the page.

Manifest (omfang) homepage screenshot, coding AI tool

Our take: Manifest by omfang suits developers building browser agents who want each page returned as a JSON map of actions, required fields and prerequisites instead of screenshots or hand-written selectors.

Main limitation: The free plan allows only 50 Manifest calls per month with no overage, and the service is an API with no consumer interface.

What is Manifest (omfang), and how does it work?

Manifest, by omfang, visits a URL, reads its accessibility tree and cross-checks the DOM to produce a JSON manifest of buttons, forms and inputs, including required fields and input types. It is aimed at developers building browser agents who want to avoid screenshots and hand-written selectors. It is used through a REST API with an API key.
