Questions & Answers

As answered by people managing Codacy and HTML4SEO.

What's the story behind your product?

HTML4SEO's answer:

HTML4SEO started with a problem we encountered on our own websites. We had long-established WordPress sites that ranked on Google's first page, but their design needed updating. We rebuilt them with Lovable. After publishing the new versions, we saw rankings fall and some sites disappear from the search results we had previously appeared in, despite trying the rendering and SEO options available to us.

We suspected that how the pages were rendered and delivered was contributing to the problem. We evaluated competing prerendering services, but their pricing was difficult to justify across a portfolio of around 20 sites when all we wanted was HTML rendering. We already had tools for SEO audits and reporting.

As developers, we decided to build the focused service we needed: deliver complete rendered HTML while preserving the JavaScript needed for interactions, with simple setup and an affordable per-site price. We used it on our own sites and observed rankings recover within about a week. This is our experience on those sites, not proof that every ranking change has the same cause or a guarantee of SEO results.

We still use the service ourselves. We opened it to others at EUR 5 per month per website so developers, agencies and site owners can get HTML prerendering without paying for a wider SEO suite.

Which are the primary technologies used for building your product?

HTML4SEO's answer:

HTML4SEO uses TypeScript and Node.js, with Fastify for the server application. Its rendering workers use Playwright and Chromium to execute public JavaScript pages and capture their rendered HTML. Redis and BullMQ support the rendering queue and cache workflow, while PostgreSQL and Prisma handle application data. The customer interface uses React and Vite, and deployment uses Docker. The service delivers rendered pages through the customer's verified domain while preserving the scripts and styles needed for browser interactions.

Who are some of the biggest customers of your product?

HTML4SEO's answer:

  • Our own team at Cloud VGP International was the first user: we built and tested HTML4SEO on the websites we manage.
  • We are not publishing a named customer roster or claiming major enterprise customers here. HTML4SEO is aimed at developers, small businesses and agencies managing public JavaScript websites.

What makes your product unique?

HTML4SEO's answer:

HTML4SEO focuses on one practical need: serving rendered HTML for public JavaScript websites while keeping scripts and styles available for browser interactions. It costs EUR 5 per month per website, including the root domain and www together. It is a focused rendering service with guided setup and cache refresh, so customers can keep using their preferred tools for SEO audits, keyword research and reporting.

Why should a person choose your product over its competitors?

HTML4SEO's answer:

HTML4SEO is designed for site owners who want a focused, affordable prerendering service. The price is EUR 5 per month per website, with the root domain and www included. A guided wizard validates the origin, domain ownership, DNS and HTTPS before activation. Rendered pages are cached, with automatic background refresh and a manual refresh option after content updates. Scripts and styles are preserved for browser interactions. Original hosting remains necessary, and compatibility should be checked for each site. The service does not guarantee search rankings or indexing.

How would you describe the primary audience of your product?

HTML4SEO's answer:

Developers, small businesses, site owners and agencies managing public JavaScript websites who need rendered HTML without a wider SEO suite. This includes teams using React and AI website builders such as Lovable, especially when managing several sites with a limited budget. Lovable/React public sites are a tested use case; other platforms and origins require compatibility checks rather than a blanket compatibility promise.
