GhostChat is a lightweight live chat widget built for indie hackers and solo founders. The widget is ~10KB gzipped — 20-30x smaller than Intercom, Tidio, or Crisp — and adds zero blocking time to your site.
Replies happen in Gmail. When a visitor messages your site, you get an email notification. Hit Reply in Gmail and your response lands in the visitor's chat widget in real time. No new dashboard to live in.
Zero cookies, zero third-party tracking. No GDPR consent banner required for the widget itself. Works with WordPress (official plugin), Shopify, Next.js, React, Squarespace, and Wix.
Free forever for 1 site. Pro at $5/mo unlocks 3 sites, 1-year history, WooCommerce context, webhooks, and branding removal. Business at $25/mo supports teams up to 5 agents.

Hey Fazier, I built GhostChat because every chat widget I tried to install on my WordPress sites tanked the page speed. Intercom, Tidio, Crisp — all 200-500KB of JavaScript loading on every page just so I could occasionally reply to a visitor. So I built one that's ~10KB. No tracking, no cookies, no consent banner. And because I'm a solo founder running multiple side projects, I made it so you reply from Gmail instead of logging into a separate dashboard. Visitor messages → your inbox → hit Reply → lands back in their chat widget in real time. Free for 1 site forever. Pro at $5/mo for 3 sites + Gmail threading + more. Built in the open on Cloudflare Workers. Would love feedback — what's confusing, what's missing, what would make you actually try it. Jacob
ok now this is something we need to get onboard asap

The UI looks clean and focused. I particularly like how quickly the value proposition is communicated. Have you considered adding a short demo video or interactive walkthrough? It could help first-time visitors understand the product faster and potentially improve conversions.
Interesting approach. Most live chat tools become bloated pretty quickly. How are you handling chat history and notifications while keeping the bundle size around 10KB?

Great question. The 10KB is just the visitor-facing widget — chat history and message storage live on Cloudflare Workers + Durable Objects (server side). The widget is vanilla JS, no framework — so no React/Vue baggage. History loads on-demand via WebSocket when the visitor opens the chat, not preloaded into the bundle. Notifications use the browser's native Push API + service worker — zero extra JS payload. The trick was treating the widget as a thin client and pushing all logic to the edge.
Really Nice Product .

The 'reply from Gmail' design is the real standout — with most chat tools the friction isn't the widget, it's being forced to live in yet another dashboard. And at ~10KB it's one of the few widgets that won't wreck a WordPress Lighthouse score. One thing I'd love clarified: when a visitor sends several separate messages, does each become its own Gmail thread or are they grouped per session? Threading is usually where the email-as-inbox approach gets messy.

I like the focus on keeping the widget lightweight. Using Gmail as the primary communication channel is an interesting approach that removes the need for another dashboard. Curious to see how users respond to the simplicity compared to larger live chat platforms.
