Web, search & AI

Scrape

One page, its images, its favicon, its Google reviews, a CEIDG record, a content moderation verdict, a site's stack.

Crawl

Whole sites: basic, deep, or every image — with limits you set and a structure you can index.

SERP

Search results, keyword research, rivals, cannibalisation, mobile tests and element counts.

Proxy

Safe fetch, stealth fetch, CORS, image transforms, RSS and XML to JSON, CSV streams, cache acceleration, an LLM relay, webhook relay.

AI

A UX audit of any URL: multi-viewport screenshots read by a vision model, with concrete suggestions.

Email
