Transcy slowing my website?

Topic summary

Shopify store reports slower performance and two page refreshes after adding Transcy for multilingual and multicurrency support, with a warning about poor visual stability.

  • A speed test on mobile shows a performance score of 68, described as very good by the responder. Screenshots were shared to illustrate the results.
  • LCP (Largest Contentful Paint) indicates the first image on mobile is heavy; compressing it is recommended to improve initial load performance. This targets the main content element that takes the longest to render.
  • The presence of transcy.js is visible in the waterfall, suggesting the app’s script may slightly impact speed. More installed apps generally degrade performance to some extent.
  • If Transcy is necessary for the business, the responder suggests accepting the trade‑off; otherwise, consider optimization or reducing other app load.

No concrete fix for the double refresh or visual stability issue was provided. The thread remains open with actionable next steps focused on image optimization and app impact awareness.

Hi!

I have a poster store on shopify imaginedprints.com, but I installed transcy to show multiple languages and currencies depending on the users location and desktop language.

Now, when you go to my website, it refreshes 2 times to load everything and slows it down. It also says my visual stability is poor. I think because of that.

Can someone help me with this?

Hi,
I tested your website with a speed test tool.
The mobile version has 68 points, which is actually very good.

According to the results shown by LCP,
you can compress the pixels of the first image on your mobile version a little smaller.

Here you can see the js from transcy (transcy.js), which may indeed affect the speed of your website a little.

If it must be an app you use, you can also ignore it.
Because the more apps installed on the website, the speed will be affected, except for apps that not affect the website speed.
