Add customer support to a Rails app in one step: live chat widget, AI chatbot that answers from your knowledge base, a public help center, and support tickets with human-approved replies. The gem injects the DeskCrew widget through a view helper or an opt-in Rack middleware (works with Hotwire, Turbo, Stimulus, Devise, importmap and Propshaft, no asset pipeline entry), registers your domain, and ships a small client that turns contact forms, feedback forms and background jobs into tickets. Free plan, no credit card. An alternative to Intercom, Crisp, Tawk.to, Zendesk or Freshdesk widgets for Rails, Sinatra and Rack apps.
