Before you build the stack
Which agent builder is best for customer support?+
If you use Intercom or Zendesk, their native agents are simplest. Otherwise Voiceflow for designed flows with actions, or Chatbase for a fast grounded bot.
Should I self-host my agent platform?+
Self-host with Dify or n8n when data control or cost at volume matters and you have operations capacity; otherwise hosted builders get you live faster.
