I built a 100% free live chat widget — now with AI customer support (open-source agent included)

Hey IH 👋

I'm a PM at the team behind Knocket — a completely free website chat widget.

The problem we saw: Most indie hackers and small SaaS builders need a way for visitors to reach them, but existing live chat tools either cost $20-50/month or require complex setup. When you're pre-revenue or bootstrapping, that's hard to justify.

What Knocket does:

1 line of code → chat bubble appears on your site's bottom-right corner
Real-time chat with visitors, plus offline contact forms
Social links hub — aggregate WhatsApp, Telegram, Instagram, Calendly in one widget
Zero-code customization — colors, greetings, avatars, work hours, all from a dashboard
100% free. No trial. No hidden tiers. Backed by Tencent Cloud infrastructure (global low-latency, SSL, GDPR-compliant)
What's new — AI customer support: We just open-sourced an AI agent that monitors your Knocket inbox and auto-replies to customers using any LLM (Claude, GPT, DeepSeek, Qwen — your choice).

Human-first mode ⭐: You get a Telegram notification, have 5 minutes to reply yourself — if you don't, AI handles it
The whole thing runs on your local machine with a Python script. No server costs. No SaaS subscription.

Fun fact: I'm a non-technical PM who built this agent entirely through "vibe coding" with AI assistance. The GitHub repo has all the gory details and lessons learned.

Who it's for:

• SaaS builders who want visitor chat without the price tag
• Indie hackers with portfolio/landing pages who want a contact channel
• Anyone tired of paying for Intercom/Crisp/Tawk alternatives

Question for the community: How are you handling customer chat on your sites right now? Paying for a tool, using email, or just... hoping people find your Twitter? Would love to hear what's working (or not) for you.
