Questions & Answers

As answered by people managing Flowproof.nl and SEOptimer.

Which are the primary technologies used for building your product?

Flowproof.nl's answer

Next.js and React with TypeScript, PostgreSQL with Prisma, Tailwind CSS, axe-core for the WCAG accessibility checks, Stripe for billing and Resend for email. Hosted on Vercel.

What makes your product unique?

Flowproof.nl's answer

Flowproof checks a website the way an AI crawler actually experiences it, not just what the robots.txt file says. Besides reading the robots.txt rules for 12 AI bots, it requests the page with a real AI user agent to catch firewalls and bot protection that silently block ChatGPT or Perplexity. It also measures how much content is in the raw HTML, because most AI crawlers do not run JavaScript. AI search readiness (GEO), SEO, schema markup, llms.txt, conversion and UX are covered in one scan, and paid plans add a WCAG 2.2 accessibility check. Every finding comes with a plain-language explanation and a concrete fix.

Why should a person choose your product over its competitors?

Flowproof.nl's answer

Flowproof combines AI search readiness, classic SEO and accessibility in one report, so you don’t need three tools to answer one question: can people and AI systems find and use my website? The advice is written for marketers and business owners, not only developers. It is available in English, Dutch, German and Spanish, it is built and hosted in the EU, and the free plan lets you scan one website without a credit card. Agencies get white-label client reports in their own branding on the Business plan.

How would you describe the primary audience of your product?

Flowproof.nl's answer

Marketers and business owners who want their website to show up in ChatGPT, Perplexity, Gemini and Google AI Overviews. Also web and SEO agencies that audit client websites and need clear, branded reports, and online shops in Europe that have to meet the accessibility requirements of the European Accessibility Act.

What's the story behind your product?

Flowproof.nl's answer

Flowproof is built by Jelle Brummans at Peelmedia, a Dutch digital agency. Search is shifting from a list of links to answers written by AI, and many websites turn out to be invisible to those systems for technical reasons their owners never see: a blocked AI bot, a firewall rule, or content that only appears after JavaScript runs. Flowproof was built to make those issues visible in a single scan and to explain how to fix them, in the language of the person who has to act on it.
