be1st.ai: the tool that tells you in 30 seconds whether your website is ready for the AI era

Most companies can't answer basic questions about their own website: Is it fast? Is it secure? Does Google see it? And with the rise of AI search, an even more important question appeared: will ChatGPT, Perplexity or Gemini find me when their user asks about the services I offer?

A classic agency audit takes days and costs hundreds of euros. Working with clients, we needed an answer in seconds. A tool covering both the technical state of a website and its AI visibility in one place didn't exist on the market. So we built it ourselves.

be1st.ai runs four audit tools against a given URL at once and returns a clear report within 30 seconds, with specific recommendations on what to fix and why.

The frontend runs on Next.js, the audit backend on Python FastAPI, and the data lives in Supabase PostgreSQL with pgvector. The AI Visibility module queries multiple AI models at once via OpenRouter (GPT, Gemini, Perplexity Sonar). Payments are handled by Stripe, invoicing by the Kros API, and measurement by a combination of GA4, PostHog and server-side conversions.

We use the exact same stack and approach on client websites. be1st.ai doubles as our technology business card: when we claim we can build a fast, secure and measurable website, this is the proof running in production.

The platform's entire foundation is open source: Next.js, React, Python, FastAPI and PostgreSQL. It's our Open by Design principle in practice: no licenses for the core of the system, no lock-in and full control over how the product evolves.
