We've been using bunnycdn for many years now with our website design agency as well! It works great in combination of other tools like cloudflare free proxy or even just pure caching servers (e.g dnsimple).
You can use it together whit your content delivery network provider too which makes everything easier when you need multiple solutions combined into one service plan that saves all expenses! Not really but i guess they could improve their UI/UX by adding more clear icons / graphics so its easyer than right click > inspect element -.- maybe this has something doen wiht my browser though? Sometimes we have issues if someones computer runs slow due high load time etc., sometimes there are latency problems because DNS might not be cached correctly from previous requests made before switching over eithin an hour ago.
