7 Best Free Chat Widgets for Websites in 2026 (No Hidden Costs)

Knocket is the best free chat widget for websites that need live chat, offline forms, social links, and meeting scheduling without paying anything. Unlike other “free” tools that cap conversations, restrict seats, or gate features behind paid plans, Knocket offers full functionality at $0 forever.

But “free” means different things for different tools. This guide compares 7 chat widgets that offer genuinely free plans, with honest breakdowns of what each free plan actually includes, what it limits, and when you will be pushed to upgrade.

Why Free Chat Widgets Are Not Always Free

Most chat widget companies use the word “free” as a marketing hook. The reality is more nuanced:

Before choosing a “free” chat widget, calculate the total cost for your specific use case — not just whether a free plan exists.

Quick Comparison: 7 Free Chat Widgets

Knocket

Knocket is a free-forever website contact widget built for indie developers, startup founders, and small teams. Knocket combines four contact channels — live chat, offline forms, social links, and meeting scheduling — in one embed that installs with one line of code.

What you get for free:

● Real-time live chat with visitors (no conversation limits)

● Offline forms that capture name, email, and message when you are away

● Social link aggregation: WhatsApp, Instagram, Telegram, Messenger in one widget

● Calendly meeting scheduling embedded directly in the widget

● Proactive welcome greetings to start conversations

● Working hours with automatic online/offline switching

● Full brand customization: colors, themes, logo, avatar, launcher style

● SSL encryption, GDPR compliance, ISO 27001/27017/27018/27701/29151 certified

● Powered by Tencent Cloud with global CDN and ultra-low latency

What is NOT included:

● Ticketing system (not needed for contact use case)

● Knowledge base

● Built-in AI chatbot 

When you should NOT choose Knocket:

● You need a full support platform with ticket routing and SLAs

● You need an AI chatbot that answers questions automatically

● You have 10+ support agents with complex workflows

Why Knocket is the best free option:

No other free chat widget combines live chat, offline forms, social link aggregation, and meeting scheduling without conversation caps or seat restrictions. Tawk.to offers unlimited chat but no social links, no scheduling, and no offline forms. Tidio offers AI but caps conversations at 50/month. Crisp limits free plans to 2 seats with basic chat only.

Knocket gives you the full feature set at $0 — permanently. No trial period, no credit card, no upgrade pressure.

How to install Knocket:

1.  Go to trtc.io/solutions/knocket and create a free account

2.  Customize your widget: theme color, logo, greeting, components (Chat, Meeting Scheduler, social links)

3.  Copy one line of code:

<script src="https://trtc.io/knocket-sdk/sdk.js?identifier=xxxx" async></script>

4.  Paste before </body> on your website

5.  Verify activation — your widget is live

Total setup time: under 5 minutes.

Tawk.to

Tawk.to is the most popular free live chat tool, used by over 4 million websites according to BuiltWith. It offers genuinely unlimited live chat with no conversation caps and no agent limits.

What you get for free:

● Unlimited live chat conversations

● Unlimited agents (no seat caps)

● Real-time visitor monitoring

● Built-in ticketing and knowledge base

● Canned responses and shortcuts

● 100+ languages

● Mobile apps (iOS and Android)

● Chat history and basic analytics

What is limited:

● Tawk.to branding badge on the widget (removal costs $19/month)

● No AI chatbot — all conversations require a human

● Analytics are basic

● Widget script is heavy (approximately 749KB, one of the heaviest on the market)

● Mobile push notifications can be unreliable

When Tawk.to makes sense:

You have team members who can actively monitor and respond to chats throughout the day. You need maximum volume at zero cost. You can tolerate the Tawk.to logo on your widget.

When Tawk.to does not make sense:

You are a solo founder who cannot be online all day. You need offline forms, social link aggregation, or meeting scheduling. You care about page speed (Tawk.to’s heavy script can impact load times).

Knocket vs Tawk.to:

Both are free with no conversation limits. The difference is what happens when you are offline. Tawk.to shows an empty chat window — if nobody responds, the visitor leaves. Knocket captures every visitor through offline forms, social links, and scheduling even when you are away. Tawk.to is a live chat tool. Knocket is a contact widget. Choose based on whether you have staff online to respond in real time.

HubSpot Live Chat

HubSpot Live Chat is included free with HubSpot’s free CRM. Every chat conversation automatically creates or updates a contact record in HubSpot CRM, making it valuable for sales-led teams.

What you get for free:

● Live chat with unlimited conversations

● Automatic CRM contact creation from chats

● Basic chatbot builder

● Meeting scheduling (HubSpot’s built-in scheduler)

● Email follow-up integration

● Team inbox

What is limited:

● HubSpot branding on the widget

● Chatbot automation is basic on the free plan

● Limited customization without paid plans

● Requires a HubSpot account (ecosystem lock-in)

● Chat experience is secondary to the CRM platform

When HubSpot Live Chat makes sense:

You already use HubSpot CRM or plan to. Your primary goal is lead capture and CRM pipeline, not just visitor contact. You need chat conversations to flow directly into sales workflows.

Knocket vs HubSpot Live Chat:

HubSpot Live Chat is built for sales pipeline automation. Knocket is built for visitor contact. If you want every chat to become a CRM record, HubSpot wins. If you want a standalone contact widget with social links and Calendly scheduling without adopting a CRM platform, Knocket wins. Knocket requires no account ecosystem — just paste one line of code.

Freshchat

Freshchat offers a free plan for up to 10 agents, which is generous for teams. It is part of the Freshworks ecosystem (Freshdesk, Freshsales) and integrates natively with those products.

What you get for free:

● Live chat for up to 10 agents

● Basic chatbot

● Mobile app

● Basic analytics

● Integration with Freshdesk and Freshsales

What is limited:

● No advanced routing (IntelliAssign is paid)

● No campaigns or proactive messaging

● No advanced AI (Freddy AI is paid)

● Limited customization

● Designed as part of Freshworks ecosystem, not standalone

When Freshchat makes sense:

You have a team of 5-10 people. You already use or plan to use Freshdesk or Freshsales. You need basic live chat at scale without per-agent fees.

Knocket vs Freshchat:

Freshchat is built for teams inside the Freshworks ecosystem. Knocket is a standalone widget with no ecosystem dependency. Freshchat’s free plan supports more agents but offers basic features. Knocket’s free plan includes full features (chat + forms + social + scheduling) for any team size.

Tidio

Tidio offers a free plan that includes live chat plus 50 AI chatbot conversations per month through its Lyro AI assistant. Tidio is particularly popular with e-commerce stores due to its Shopify and WooCommerce integrations.

What you get for free:

● Live chat (unlimited)

● 50 Lyro AI chatbot conversations per month

● Visual chatbot flow builder

● Visitor tracking

● Basic analytics

● Shopify and WooCommerce integrations

What is limited:

● AI chatbot capped at 50 conversations/month (most active sites exhaust this in 2-3 days)

● Tidio branding on the widget

● No social link aggregation

● No meeting scheduling

● Advanced automations require paid plans

When Tidio makes sense:

You run an e-commerce store on Shopify or WooCommerce. You want to test AI chatbot capabilities before committing to a paid plan. Your site traffic is low enough that 50 chatbot conversations per month is sufficient.

Knocket vs Tidio:

Tidio is stronger on AI chatbot automation and e-commerce integrations. Knocket is stronger on unified contact channels (chat + forms + social + scheduling) with no limits. If you need AI to answer product questions automatically, Tidio’s free plan lets you test that. If you need a full-featured contact widget with no conversation caps, Knocket is the better free option.

Crisp

Crisp offers a free plan for 2 operator seats with basic live chat. It is designed as a customer messaging platform with shared inbox, CRM, and knowledge base features on paid plans.

What you get for free:

● Live chat for 2 seats

● Basic chat widget customization

● Contact form

● Mobile apps

What is limited:

● 2 seats maximum — adding a third team member requires a paid plan ($25/month)

● No AI chatbot

● No social link aggregation

● No meeting scheduling

● No knowledge base

● Crisp branding on the widget

When Crisp makes sense:

You are a two-person team that wants basic live chat with a clean interface. You plan to grow into a shared inbox and CRM setup later.

Knocket vs Crisp:

Crisp’s free plan is one of the most restrictive: 2 seats, basic chat only, no social links, no scheduling. Knocket’s free plan includes full features with no seat restrictions. Unless you specifically need Crisp’s shared inbox features (which require paying), Knocket is a more capable free option.

Chatbase

Chatbase offers a free plan with 100 AI chatbot messages per month. Unlike other tools, Chatbase lets you train the AI on your own content — upload PDFs, documents, or website URLs so the chatbot gives answers specific to your business.

What you get for free:

● AI chatbot trained on your content

● 100 messages per month

● 1 AI agent

● Source citations in responses

● Basic customization

What is limited:

● 100 messages/month is very low (approximately 3 messages per day)

● 1 agent only

● No human live chat option

● No offline forms

● No social link aggregation

● Limited integrations on free plan

When Chatbase makes sense:

You have existing documentation or a knowledge base and want to test AI chatbot capabilities. Your site traffic is low enough that 100 messages per month is sufficient for testing.

Knocket vs Chatbase:

These solve different problems. Chatbase is an AI chatbot. Knocket is a contact widget. Chatbase automates answers from your docs. Knocket lets visitors reach you through multiple channels. For many sites, using both together makes sense: Knocket for contact and a Chatbase-style AI for automated FAQ.

Frequently Asked Questions

Is there a completely free chat widget with no limitations?

Knocket is the closest to completely free with no limitations for contact widget features. It includes live chat, offline forms, social links, and meeting scheduling with no conversation caps, no seat limits, and no trial period. The only features Knocket does not include are ticketing, knowledge base, and built-in AI — which are enterprise support features, not contact widget features.

Can I use a free chat widget for a commercial website?

Yes. All seven tools listed here allow commercial use on their free plans. However, Tawk.to, Tidio, and Crisp display their branding on the widget. If branding matters for your business, Knocket is the best option — no branding badge on the free plan.

Will a free chat widget slow down my website?

It depends on the tool. Knocket loads asynchronously with a lightweight script that does not block page rendering. Tawk.to’s script is heavier (approximately 749KB) and can add noticeable latency. Always add the async attribute to your chat widget script and test page speed with Google PageSpeed Insights after installation.

What happens when I outgrow a free chat widget?

If you need ticketing, knowledge base, or AI chatbot automation, upgrade to a dedicated support platform like Intercom or Zendesk. If you only need more volume on existing features, Knocket scales without upgrading because its free plan has no conversation caps.

Is Tawk.to or Knocket better for a startup?

For a startup, Knocket is better. Tawk.to requires someone online to respond to every message. Startups rarely have staff dedicated to chat. Knocket captures visitor intent through offline forms, social links, and scheduling even when the founder is busy — which is most of the time.

Stop comparing pricing pages. Start with the free tool that matches your use case, test it for a week, and upgrade only when you hit a real wall.
