Show HN: ChatSpark – Live chat widget for solo operators
chatspark.dev
ChatSpark is a lightweight, embeddable live chat widget for solopreneurs and small business owners who handle support themselves.
Single script tag embed. One dashboard. Real-time messaging via WebSocket. Email/push notifications. Offline mode with leave-a-message form. Optional AI auto-replies from your FAQ content.
Built with Next.js, Node.js, WebSocket, PostgreSQL. Deployed on Kubernetes.
Free tier: 1 widget, 50 conversations/month. Pro: $12/mo. Business: $29/mo with AI replies.
The main design constraint was simplicity. No multi-agent routing, no ticket systems, no onboarding wizard. Paste one script tag, start chatting.
Honest limitations: it's single-operator only, no team features. If you have more than one support person, this isn't the right tool. It's specifically for the "I do everything myself" crowd.
