Frequently asked questions
Are your extensions really free to try?
Yes. JS Like Box Slider includes 100 page views per month on the free plan — enough to install, configure and test on your live site before upgrading.

Where do I manage my API key and usage?
Log in at jsns.eu and open API Keys & Usage in your account dashboard. You can generate keys, check monthly views and upgrade your plan there.
