Botstar is a marketer's chatbot paradise that the developer will love. Quite literally there are very few comparable products on this market, and I've explored quite a few of them.

Here are the perks that I see:
1) White label resellers for a 3 stack? Snag that 5 stacks because you could sell on of these chatbots for that much. (You'll have to do the work, but hey its an opportunity enabler)

2) Dialogflow is integrated and ready to go. Quite literally this makes implementing NLP you've been working on before super easy.

3) Support has been awesome and very helpful/proactive. On top of that, they've got stellar documentation.

4) They have a live chat built-in, meaning you don't have to javascript sync another provider.

5) Awesome templates to get you started, with valuable onboarding and marketing popups/tools.

6) An incredible amount of ways to customize your bot if you know a little about API/webhooks, even without it you've got Zapier/Integromats.

Asides from that, they're platform itself is buttery smooth and their CMS has a LOT of potentials.

Heck if you're just getting started on how data flows you can literally use this tool to practice, its that good.

I think its a steal, 5 tacos, lemme stack more.
