Description

Make your second page load feel faster and help improve your chances of higher conversion rates.

Boostly improves the shopping experience by making store pages feel faster when navigating. By preloading, pages are already loaded before the click, which reduces delays and makes loading times in the store smoother. Boostly works with all themes and requires only minimal setup, so that performance remains stable when updating or switching themes. Faster loading times can increase your Add-to-Cart chances.

Fully guided setup from install to seeing your optimized results.
Compare clear before-and-after scan results for your store.
Preloads internal pages so navigation feels faster for customers.
Scan and optimize multiple themes without custom coding.
Fits seamless into any Shopify theme, helping your store convert more visitors.

Pros

1-Click setup for quick implementation
Significantly improves page load times by loading apps on user interaction
Offloads heavy code snippets to enhance response time
Pre-loads pages in the background, increasing subsequent page load speeds
Simple setup with only one line of code added to the theme
Innovative technology designed to make pages feel almost instantaneously loaded
Potential to increase conversion rates by improving page speed

Cons

May not be effective for all types of websites
The actual performance boost may vary depending on existing site speed and complexity
Limited control over the specifics of which code snippets are offloaded
Dependency on the app’s algorithm for app loading, which might not suit customized needs
Potential conflicts with other plugins or custom scripts

Can't even use this app as I'm getting this weird error. Chrome has built-in safety features to protect you while you browse — like Google Safe Browsing, which recently found phishing on the site you're trying to visit. Phishing sites pretend to be other sites to trick you. Even sites that are normally safe are sometimes compromised by attackers. Let us know if you think there's been a mistake and that this site doesn't pose a danger. Only visit this unsafe site if you're sure you understand the risks.

We have been using Boostly for a couple of weeks now and the results are astonishing. Previously our site has been rather slow and immediately after installation it increased above average. We didn't have to do anything apart from the installation: nearly feels like magic! Having said this: it's not just the speed score. Our site also "feels" subjectively faster on front-end. Especially load time of imagery seems now instant without any delay. Highly recommended to everyone wanting to improve site performance!
