5 Best WhatsApp Chat Widgets for Websites in 2026 (Compared)

Not every "WhatsApp widget" is solving the same problem. Some are static buttons, some are full CRMs with a WhatsApp button attached. Here's how the main options actually compare, based on what they publish about their own products.

Elfsight

A general-purpose widget builder (chat, reviews, galleries, forms) that includes a click-to-chat WhatsApp widget among dozens of other widget types. Starts around $9/month. It's the closest in spirit to a dedicated WhatsApp tool, but WhatsApp is one feature among many rather than the focus — no exit intent, no scenarios, no workspace for managing multiple widgets as a team.

WATI

A full WhatsApp CRM built on the Business API, starting around $49/month. It's aimed at teams that need multi-agent inboxes, automation, and broadcast campaigns — genuinely powerful if you're past the point of one person replying from a phone, but a lot of platform for a business that just wants a chat button on its homepage.

Crisp

A multi-channel support inbox (live chat, email, WhatsApp, and more) starting around $25/month. WhatsApp is one channel it can plug into rather than its core focus, and it comes with the complexity of a full helpdesk platform — useful if you already want that, overkill if you don't.

Respond.io

Another WhatsApp-focused CRM, starting around $79/month, built for businesses running WhatsApp as a serious sales and support channel at volume, with automation and multi-channel routing. It's the most expensive option here and priced for teams that need that depth.

WhatsChat

Built specifically around the click-to-chat use case rather than treating WhatsApp as one channel among many: multiple trigger scenarios (default, exit intent, time on page, and more), a brand kit so the widget matches your site, a shared workspace with no per-seat pricing, and a flat €8/month Pro plan with a free tier to start on. No WhatsApp Business API required, since it works on standard wa.me deep links — the same mechanism every option on this list eventually opens.

How to actually choose

If you need multi-agent routing, automation, or broadcast campaigns, WATI or Respond.io are built for that — expect to pay for the depth. If you want a widget alongside a dozen other website tools you're already using, Elfsight or Crisp fit that role. If what you actually want is a WhatsApp-native widget with real trigger scenarios and your own branding, without paying for CRM features you won't use, that's the gap WhatsChat is built to fill.
