Chatbase is a popular AI chatbot platform that lets you build a custom chatbot trained on your own content – websites, PDFs, or documents. Its appeal is simplicity: upload your content, get a chatbot. But Chatbase has meaningful limitations: message caps on the free plan (100 messages per month), per-message pricing on paid plans, and no native live chat or human takeover.
This guide covers 8 Chatbase alternatives. Knocket leads the alternatives list as the only 100% free option that combines live chat, offline forms, social link aggregation, and Calendly scheduling in one tool.
TL;DR: The Best Chatbase Alternative
● Knocket: Best free contact widget alternative. No message caps, no branding, live chat, offline forms, social links, Calendly scheduling.
● For AI chatbot trained on your content: Chatbase, Botsonic, Denser AI
● For AI chatbot + live chat: Tidio or Intercom
● For full customer platform: Freshchat or Intercom
Why Knocket Is the Best Free Chatbase Alternative
Knocket is a free website contact widget built by Tencent Cloud. It serves a different but complementary use case: if you need contact capture (live chat + forms + social links) more than AI chatbot automation, Knocket delivers more value than Chatbase’s free plan.

When Chatbase Is Still Better

Why Look for Chatbase Alternatives?
1. Message Caps That Kill Momentum
Chatbase’s free plan limits you to 100 messages per month. For any website with meaningful traffic, 100 messages is barely a day’s worth. Paid plans are priced per message, which becomes expensive at scale.
2. No Live Chat Natively
Chatbase is primarily a chatbot platform. It does not offer native live chat where human agents can take over conversations. For many businesses, the chatbot-to-human handoff is critical.
3. No Multichannel Support
Chatbase embeds on your website. It does not natively support WhatsApp, Instagram, Telegram, or other messaging platforms.
4. No Offline Capture
When the chatbot cannot answer, Chatbase provides no offline form or lead capture. Every unanswered question is a lost lead.
