eStranky.cz (and the Slovak eStranky.sk) is a free website builder with a built-in Smartsupp integration — no code editing required. This guide shows how to grab your Smartsupp chat key, activate the integration in your eStranky admin, and verify that the chat widget appears on your site.
The guide is divided into the following sections:
Get your Smartsupp chat key
In your Smartsupp dashboard, open Settings → Chatbox → Installation and copy your chat key — a short identifier you'll paste into eStranky in the next step.
Activate Smartsupp on eStranky
Sign in to your eStranky admin and open the section where third-party services are configured (typically Profil → Doplňky or Nastavení). Find the Smartsupp option, paste your chat key, and save the changes — eStranky will inject the Smartsupp script into your site automatically.
Verify the installation
Open your eStranky website in a new browser tab and refresh. The Smartsupp chat widget should appear in the corner of your page. Then sign in to the Smartsupp dashboard to start chatting with visitors.
Tip: If the chat widget doesn't appear after activation, clear your browser cache or open your site in an incognito window. Still no widget? See Why can't I see the chat on my website?
