When BotEngine was released, I was an instant customer. I built and deployed bots on at least four other platforms while waiting for BotEngine and every one of those platforms was problematic. Either they weren't reliable and would malfunction without warning, or they were free and then not free and then kind of free and then not, etc, so i would gladly recommend.
It also has a number of templates, covering bots built for shopify, woocommerce, livechat, restaurants and other templates which helped me understand how the different blocks come together to build a complex chabot. Voice conversation integration with alexa echo/google home is also coming up, along with web widgets if the existing twilio, telegram, facebook integrations are not enough already.

Pros: First, ive to give credits to the development team for working hard. Bugs fixing, features enhancement, UI improvements and so much more. We've used manychat, funneldash, segmate, motion ai and others and personally we felt Activechat beat them all in terms of pro-activeness, features (standalone bot, NLP integration, custom smtp, woocommerce integration, etc).
