Thanks in advance!
You can always use Elfsight widgets for free, using free Lite subscription plan. It’s fully-featured plan with no limitations in functionality or customization settings. Moreover, there’s no any time restrictions, so you can use as longer as you need.
There’s views limit, but if there won’t be enough you can always upgrade it for the subscription plans with rather low costs.
Anyway, if you are interested in using our widgets, you can always contact us and we’ll find the solution exactly for your use case.
Onsano could be the solution
