Welcome to community forums! @Razvan
It is indeed true that we lack documentation for now but we are working on them. We have finished few of the documentation for developers recently and will move forward to work on client documentation.
We have been operating since 2018 and for stability, we suggest you to get a trial and try it out yourself :) https://my.wisecp.com/en/trial-license/92

We have also rolled out so many web hosting control panel integrations recently in one of our updates. https://docs.wisecp.com/en/kb/v2-0-3
So VestaCP is also included in it.

You can also find all the hosting control panel modules for WISECP here: https://www.wisecp.com/en/integration
 

Welcome to WISECP Community Forums @rolan
After 30 days trial,  WISECP software will show License Warning on the domain it is registered on. No functions will work until it is renewed.
However if you are an active member of our community, we can extend your trial for 30 days on request.
