About JJ Labs

JJ Labs builds custom websites, landing pages and web apps for businesses that want to be found on Google and close deals on WhatsApp. Every project starts with one simple question: what needs to happen after a visitor lands on the site?That is why there are no ready-made templates and no drag-and-drop builders. The code is our own, fast and indexable, the price is fixed before work begins, and you talk directly to the developer — from the first brief to support after launch.

Frequently asked questions

FAQ

  • It depends on the scope. A lean landing page starts well below a complete business website, and web apps are quoted case by case. Every proposal comes with a fixed price before work begins — you know exactly what you will pay.

  • Landing pages are usually ready in about a week. Business websites take two to four weeks, and web apps depend on their features. The timeline is part of the proposal, together with the price.

  • Yes. Every project is built mobile first, because that is where most traffic comes from. The layout is tested on small screens before it moves to desktop.

  • Yes. We take care of domain registration, hosting, the SSL certificate and professional email. If you already have all that, we migrate the site without taking it offline.

  • It can, and that is our standard. Buttons lead straight to a WhatsApp conversation, and we set up the Google tag and conversion tracking so you know which campaigns actually bring in clients.

  • You keep talking to the person who built it. Content changes, new pages and improvements can be made at any time, without starting over from scratch.
