Great tool, needs more support staff and more documentation. Could be a bit unreliable for production sites. But it is not meant to be. It's great for it's core purpose (education, demos and so on) definitely a game changer. Recommended!
Sorry about the docs part, we are working hard on it. New docs are available at docs.instawp.com.
Please let me know what we have missed regarding the support, I am here to help or you can contact me via support@instawp.io.
Reliability shouldn't be an issue, although we are not meant for production as you mentioned, the uptime should still be good. What is the problem you face?
InstaWP is a vital part of our customer sales funnel: we use it to power our demo site. We have been using InstaWP for this purpose for months and have never experienced downtime.
The feature set is excellent and getting more powerful every week. As a business owner, I'm seriously impressed by the pace and quality of the InstaWP service.
