About the Castor: Growth & Design Studio
Castor combines store design tools with catalog management in one app. Build custom popups, banners, announcement bars, and widgets from scratch or use ready-made templates to capture leads and drive conversions. Create signup forms that automatically issue discount codes to grow your email list.
Show smart product recommendations to customers with targeted popups and widgets. Track exact sales revenue generated by each campaign and compare A/B test performance to see what works best for your store.
On the backend, bulk edit your entire product catalog in seconds. Update prices, tags, SEO metadata, and product details across multiple items at once. No need to edit products one by one—make changes to your whole catalog quickly and keep everything optimized for search engines.
