About the Project
Webmatik is an AI-powered website growth audit platform built to replace five separate tools — PageSpeed, Lighthouse, Ahrefs, accessibility checkers, and AI search visibility trackers — with a single report. Built from the ground up as a modern Next.js 16 SaaS, it scans any website across 70+ technical and strategic signals in eight categories: Conversion, Retention, Performance, UI/UX, SEO, GEO (AI Search Visibility), Accessibility, and Security. Each audit produces a Growth Score, a prioritized action plan, and concrete fix instructions — written so a non-technical business owner can hand them to a developer and ship.
The platform sits at the intersection of traditional SEO tooling and the emerging AI search era. While most auditors only look at code and Lighthouse metrics, Webmatik also runs eight LLM queries across ChatGPT, Gemini, and Perplexity to measure how visible a brand is in AI-generated answers — the new battleground for organic discovery. Combined with GPT vision analysis of full-page screenshots, the platform sees both the underlying code and the actual user experience, catching conversion and UX issues that pure HTML parsing misses.
Webmatik is built with TypeScript and Next.js 16 App Router, backed by Supabase for auth, storage, and PostgreSQL persistence. It uses Puppeteer for full-page screenshots, DataForSEO for keyword and on-page metrics, and Stripe for subscription billing across multiple tiers and audit volumes. Background processing handles long-running AI tasks asynchronously — initial results return in 30-40 seconds while vision analysis and GEO scanning complete in parallel — so users get a usable report immediately and a fully enriched one within ~90 seconds.
Beyond the web app, Webmatik exposes a full REST API with HMAC-signed webhooks, an OpenAPI 3.1 specification, a WordPress plugin published on the official directory, a Chrome extension on the Web Store, and PDF report generation for agencies that want to white-label deliverables. The platform serves audits to individual founders, marketing teams, and agencies — including its own integration with Belov Digital’s WP Cloud Lab maintenance service, where Webmatik powers monthly health reports for managed clients.

Our Goals
Most website auditors leave business owners with raw technical numbers they can’t act on — and the few that go deeper cost enterprise prices and take weeks to deliver.
We set out to build a platform that delivers the depth of a senior growth team’s audit in 90 seconds. Webmatik combines real SEO data, on-page analysis, AI vision review, and the new dimension of AI search visibility into a single report that a founder can read on their phone and immediately know what to fix next — written in plain language, prioritized by real business impact, and exportable as a branded PDF for clients or developers.
Solution
Webmatik isn’t just another SEO checker — it’s the first audit platform that sees both your code and how AI search engines see your brand, in one report.
Built on Next.js 16 with TypeScript, Supabase, and Stripe, Webmatik runs a three-phase audit engine. Phase 1 returns a working result in 30-40 seconds across SEO, performance, security, and accessibility. Phases 2 and 3 enrich it in the background with OpenAI vision analysis of full-page screenshots and 16 parallel LLM queries across ChatGPT, Gemini, and Perplexity to measure AI search visibility. Combined with DataForSEO keyword data, Google PageSpeed metrics, and a custom broken-link checker, every audit covers 70+ growth signals across eight categories — with HMAC-signed webhooks, a public REST API, a WordPress plugin, and PDF exports for white-label use.
AI Vision + GEO Scanner
The platform combines GPT-5.4 vision analysis of full-page screenshots with 16 parallel queries to ChatGPT, Gemini, and Perplexity to measure AI search visibility — a dimension no traditional SEO tool covers. Most auditors only see HTML; Webmatik also sees the actual rendered design and how the brand appears in AI-generated answers.
Action Plan with Real Business Impact
Every audit produces a prioritized action plan with critical / important / nice-to-have tiers, written in plain business language with concrete fix instructions, estimated effort, and projected score impact. A non-technical founder can read the report on their phone and hand it directly to a developer — no translation layer needed.
Full Public API with Webhooks & PDF Export
Beyond the web app, Webmatik exposes a REST API with HMAC-signed webhooks, an OpenAPI 3.1 spec, a WordPress plugin (WordPress.org directory), a Chrome extension (Web Store), and server-side PDF generation. Agencies and SaaS products integrate Webmatik audits directly into their workflows — Belov Digital’s own WP Cloud Lab uses the API to power monthly health reports for managed clients.
Results
We launched a production-grade AI audit platform that runs in 90 seconds, scans 70+ growth signals across 8 categories, and is already powering monthly health reports for paying clients of a maintenance agency.
Webmatik shipped as a complete SaaS product — Next.js 16 frontend, Supabase backend, Stripe subscription billing across two paid tiers, a full public REST API with webhooks, a WordPress plugin published on the official directory, a Chrome extension on the Web Store, and server-side PDF report generation. The platform combines nine data sources — OpenAI vision, ChatGPT, Gemini, Perplexity, Google PageSpeed, CrUX, Google Search Console, DataForSEO, and a custom broken-link checker — into a single coherent audit. Deployed on Hetzner Cloud with Caddy auto-SSL and zero-downtime GitHub Actions deploys, the platform consistently delivers full audits in under 100 seconds, including AI vision and GEO scanning. Webmatik isn’t just a tool that audits websites — it’s a complete growth platform that replaces five separate SaaS subscriptions, making senior-level growth analysis accessible to founders, marketers, and agencies who previously couldn’t afford it.
