Knocket is a 100% free-forever website contact widget that combines live chat, offline forms, social links, and meeting scheduling in one embed. It installs with one line of code in under 5 minutes — no backend, no dashboard learning curve, no credit card.
If your website visitors want to reach you but can’t figure out how, this is the fix.
What Is Knocket?
Knocket is a free website contact widget for SMBs and developers that replaces scattered contact buttons with one unified communication surface.
One widget. Four capabilities:
● Live chat — real-time visitor-to-owner messaging powered by Tencent Cloud with ultra-low latency
● Offline forms — visitors leave their name, email, and message even when you’re away
● Social links — WhatsApp, Instagram, Telegram, and Messenger aggregated in one tap
● Meeting scheduling — embedded Calendly integration, no redirect needed
Knocket also includes:
● Proactive engagement — customizable welcome greetings that start conversations before visitors bounce
● Working hours — automatic online/offline switching based on your availability schedule
● Brand customization — color picker, preset themes, logo upload, custom welcome messages, and two launcher styles (circular and extended)
Knocket is 100% free forever. Core chat features and full widget customization are included with no hidden fees.
What Problem Does a Website Contact Widget Solve?
Most websites scatter their contact options across multiple pages and formats. A mailto link lives in the footer. A contact form sits on a separate page. Social icons float in the sidebar. A booking link hides three clicks deep in the navigation.
The result: visitors who want to reach you can’t figure out the fastest way to do it. On mobile, half the links break or redirect to apps that aren’t installed.
You’re not lacking interest from visitors. You’re leaking intent.
Before Knocket | After Knocket |
4+ contact entry points scattered across pages | One widget, one click, all channels |
Visitors guess which channel gets a reply | Visitors choose how they want to connect |
Offline visitors leave with nothing captured | Offline form captures every message and contact |
No social aggregation — each platform linked separately | WhatsApp, Telegram, Instagram, Messenger in one tap |
Booking requires redirect to external scheduling tool | Calendly embedded directly inside the widget |
Knocket solves this by giving every visitor one clear entry point. They click the widget, pick their preferred channel, and connect — whether you’re online or not.
How Does Knocket Compare to Intercom, Zendesk, and LiveChat?
Knocket is a lightweight alternative to Intercom, Zendesk, and LiveChat for teams that need fast customer contact without full support infrastructure.

Unlike Intercom and Zendesk, Knocket does not include ticketing, knowledge bases, or AI chatbot features. That is intentional. Knocket is built for teams that need a simple, fast way to let visitors make contact — not a full customer support platform.
If you already run a support team with ticket queues and SLA tracking, Knocket is not the right tool. If you need a contact widget that works out of the box in 5 minutes and costs nothing, Knocket is purpose-built for that.
How Do I Add Knocket to My Website?
Knocket installs with one line of code. No npm packages, no API keys, no build step. The full setup takes under 5 minutes.
Step 1: Customize your widget.
After signing up at Knocket - Free Website Contact Widget & Live Chat for SMBs & Developers, Knocket walks you through a visual setup wizard:
● Theme color — pick from 12 preset colors or add a custom brand color
● Brand logo — drag and drop or click to upload your logo
● Components — toggle on or off:
○ Chat — enable real-time conversation with your visitors
○ Meeting Scheduler — allow users to book a meeting via your scheduling link (e.g., Calendly). Just paste your Meeting URL
● Greeting — set your welcome message (default: “Hello. How can I help you today?”)
A live preview on the right shows exactly how the widget will look on your site. More configuration items can be set up later — just click Next when you’re ready.
Step 2: Copy and paste one line of code.
Knocket generates a single script tag with your unique identifier:
<script src="https://trtc.io/knocket-sdk/sdk.js?identifier=xxxx" async></script>Click “Copy to clipboard” and paste it just before the closing </body> tag on your website.
Step 3: Verify activation.
Go to your website and check if the contact widget appears. Knocket automatically checks activation — you’ll see “Checking activation…” until the widget is detected on your site.
Step 4: Start using.
The widget is live. Visitors see your branded welcome greeting and can start chatting, leave an offline message, or book a meeting — all from one surface. Knocket loads asynchronously and does not slow down your page.Four steps. One line of code. Your visitors can now reach you from one place.
Who Is Knocket For?
Knocket is designed for teams and individuals who need a simple, fast contact surface on their website without adopting heavyweight support software.
● SaaS founders — collect early user feedback through direct chat at zero cost. Get real bug reports, feature requests, and user intent without setting up a support system.
● Small businesses and storefronts — turn website visitors into conversations. Proactive welcome greetings build trust and reduce bounce before visitors leave.
● Freelancers and agencies — deploy one reusable, brandable widget across all client sites. Social link aggregation and Calendly integration replace three separate tools.
● Developers — ship production-ready contact UX with one line of code. No dependencies, no maintenance, no backend.
Knocket is not designed for large support teams that need full ticketing systems, knowledge bases, AI chatbots, or SLA management. For those use cases, Intercom or Zendesk is a better fit.

Knocket is built on Tencent Cloud infrastructure with enterprise-grade security and compliance:
● SSL encryption on all connections
● GDPR compliant — meets European data protection requirements
● ISO 27001 — information security management
● ISO 27017 — cloud security controls
