Any site, any stack. There's nothing to install first.
The crawl runs on our servers, so your laptop stays quiet.
Prioritised issues in plain English, shareable with one link.
Why it wins
Health, GEO and Accessibility stay separate. A tidy sitemap can't hide pages that nobody can use or cite.
See why an issue matters, how to fix it, and every page it touches. Then hand it to the person who owns the work.
Large crawls run in the cloud and open like any other report. Your browser gets the useful bits, not the burden.
GEO
ChatGPT, Perplexity and AI Overviews read your site differently. Spronta checks the signals that decide whether you get cited: answerable content, structured data, authorship, llms.txt, semantic markup.
Share & export
Send a public link no login can gate, export issues as CSV or the whole report as JSON, and let your agents pull everything over the API and MCP.

Before and after
Compare any two crawls for score changes, pages added or removed, and issues that appeared or disappeared. Older reports tell you when a newer one exists, too.
Agent-native
Everything on this page is a tool call away. The hosted MCP server exposes 18 tools — crawls, reports, fixes, monitoring — and the REST API speaks the same JSON. One key, no scraping, no glue code.

Every crawl runs 148 checks across 17 categories: technical SEO, indexability, links, redirects, titles and meta, canonicals, structured data, performance, security, accessibility (WCAG) and GEO — the signals AI search engines read. Each issue comes with a plain-English explanation of why it matters and how to fix it.
Yes. Turn on JavaScript rendering and Spronta drives a real headless Chrome, lets each page hydrate, and audits the post-JavaScript DOM — so content, links and meta tags injected by React, Next.js or Vue are seen instead of missed.
GEO (Generative Engine Optimization) measures how ready your pages are to be cited by AI search — ChatGPT, Perplexity and Google AI Overviews. Spronta checks answerable content, structured data, authorship, llms.txt and semantic markup, and scores each page and the whole site.
Crawls run in the cloud, so six-figure page counts open like any other report. The free Hobby plan covers 1,000 pages per crawl; Pro raises that to 50,000 pages per crawl, with monthly credits to match and prepaid top-ups beyond.
Every report has a public share link that needs no login and can be revoked any time. You can also export issues as CSV, the whole report as JSON, or let agents pull everything over the REST API and MCP.
