Why Most Chat Widgets Are Too Heavy
The average chat widget weighs 100-180 KB and takes seconds to load. That's a massive problem for real-world users.
Slow Load Times
Heavy widgets (100-180 KB) take 3-8 seconds to load on 3G connections, frustrating users before they can even ask a question.
Battery Drain
Bloated JavaScript drains mobile batteries with unnecessary CPU processing. Your customers notice and leave.
Poor SEO Impact
Heavy widgets hurt Core Web Vitals, increasing Total Blocking Time and lowering your Google rankings.
| Chat Widget | Size (gzipped) | 3G Load Time | Impact |
|---|---|---|---|
| Zendesk | ~180 KB | ~7-8 seconds | Very High |
| Drift | ~150 KB | ~6-7 seconds | High |
| Intercom | ~100 KB | ~4-5 seconds | High |
| Crisp | ~50-60 KB | ~2-3 seconds | Medium |
| The Chat Widget | 3 KB | ~0.2 seconds | None |
* Load times estimated on 3G connection (~750 Kbps). The Chat Widget is 20-35x smaller than competitors.
Why The Chat Widget Is Different
Built from the ground up for performance, not features. Every byte matters.
Only 3KB
Our entire widget — including UI, WebSocket connection, and real-time messaging — weighs just 3 KB gzipped.
That's smaller than most company logos.
Works on 3G & Slow Connections
Loads in under 0.2 seconds on 3G. Degrades gracefully on even slower connections. Your customers can always reach you.
Tested on real-world mobile networks globally.
Zero Dependencies
No jQuery. No React. No frameworks. Just pure, optimized vanilla JavaScript that loads instantly.
Every kilobyte of bloat has been eliminated.
Edge-Powered Delivery
Served from 300+ global edge locations via Cloudflare. Built for low-latency worldwide delivery (often tens of milliseconds), not centralized 80-200ms paths like many competitors.
Faster than centralized chat widgets from anywhere.
Real-World Benefits
A lightweight chat widget doesn't just load faster — it improves your entire business.
Better SEO Rankings
Keeping Core Web Vitals healthy can help with SEO. Heavy widgets often hurt performance scores; ours is designed to minimize impact.
Higher Conversions
When the widget loads instantly, users actually use it. Slow widgets get ignored. Fast ones get engagement.
Global Accessibility
Works everywhere — from San Francisco to rural India. Heavy widgets exclude customers on slow networks. We include them.
