About this plugin

Add a product from one store and CompareDock finds the same product in the others, then shows a clean comparison with direct links. Visitors can open a price history chart and ask for an email when the price drops. Product data comes from SerpApi, using your own key.

Questions

Do I need an API key?

Yes. All product data comes from the SerpApi search API, so you need your own SerpApi key (they have a free plan). The plugin does not scrape store websites.

Which stores and countries work?

Amazon (21 countries), eBay (17 sites) and Walmart (US). More stores are planned.

Can I change how it looks?

Yes. Switch between 10 designs in CompareDock > Designs, change the colour, add your own CSS per design, or copy a template file into your theme.

Does it slow down my site?

No. Prices are refreshed in the background with WP-Cron, and visitors only load a small CSS file and a small script when they open price history or alerts.
