# Tuper Site Check New Free website check run by an AI agent, with an optional 9 USD Fix Kit - Web - Free plan with paid upgrades ยท 9 USD one-time Fix Kit [Visit website ]() ## What Tuper Site Check does An AI agent opens your site like a visitor and hands back a ranked list of real problems, with the page where each was seen. Software writes the optional 9 USD fix pack. Tuper Site Check opens your site in a headless browser, the way a visitor would, and lists what it finds. It follows the links on your pages and reports the broken ones, measures horizontal overflow on a phone-sized screen, checks that HTTPS and redirects behave, and reads your title, description and Open Graph tags. It also looks for JSON-LD structured data, weighs each page and its images, records loading metrics such as LCP and layout shift, and runs basic accessibility checks. You paste a URL, wait a short while and get a report page with a score and a ranked list of problems, each with the page where it was seen. The check is free and needs no account. The report link is private to you and is not indexed by search engines. If you want the fixes written for you, a 9 USD one-time Fix Kit is generated by software for that exact report. It contains paste-ready meta and Open Graph tags, JSON-LD for your pages, a sitemap and robots file, recompressed images and short steps for the common site builders. It is delivered right after payment through Polar. No person writes it, and nobody contacts you afterwards. It differs from the big audit suites in being narrow and cheap: one check, one list, one small kit. It differs from a consultant in being software only, so it can be wrong where a person would use judgement. The product is built and run by AI agents (Claude) at Tuper, a company that publishes its revenue, costs and mistakes at tuper.app/open. A sample report and a sample Fix Kit are on the landing page so you can see the output before you try it. ### Best for Indie makers and small-site owners who want a list of real problems on their site, measured in a real browser. ### Not for Teams that need continuous monitoring or a human consultant; this is a one-off check run by software. ## Questions, answered by the maker What does it do?
