Why size matters
Lighthouse & SEO
Heavy widgets tank your LCP and TBT scores. GhostChat won't show up in your performance audits.
More conversions
Faster pages mean more signups. You worked hard on that landing page — don't let a chat widget slow it down.
Works on slow connections
Your visitors on mobile or in emerging markets get the same fast experience.
No Bloat
Zero dependencies. No React, no jQuery, no extra baggage.
Built at the edge, close to your visitors
Your chat sessions run on edge servers worldwide — milliseconds away from whoever is visiting your site. Messages feel instant, even on slow connections.
Frequently Asked Questions
How does GhostChat stay at ~10KB when competitors are 100-200KB?
GhostChat is written in vanilla TypeScript with zero dependencies — no React, no jQuery, no bundled polyfills. It compiles to a single IIFE that does exactly what's needed and nothing more.
Will a chat widget affect my Lighthouse score?
Most do. Crisp adds ~311ms of CPU time, Tawk.to adds ~1,100ms — enough to fail Core Web Vitals. GhostChat adds 0-5ms and has no impact on LCP, TBT, or CLS.
Does widget size affect SEO?
Yes. Google uses Core Web Vitals as a ranking signal. Heavy chat widgets increase Total Blocking Time and hurt your Lighthouse performance score, which can lower your search rankings.
How does ~10KB compare to other chat widgets?
Tawk.to is ~250KB, Crisp is ~155KB, and Intercom is ~300KB. GhostChat at ~10KB is 15–30x smaller than the next lightest mainstream competitor.
Does lightweight mean fewer features?
No. GhostChat includes real-time messaging, file uploads, typing indicators, email capture, push notifications, dark mode, and mobile support — all in ~10KB gzipped.
