10 Best Chatbase Alternatives of 2026

Chatling is the value pick for Chatbase users who want more room per dollar. The Starter plan is $25 a month, or $21 billed annually, and includes 1,750 AI credits, 2 agents, 2 seats, a 10 million character knowledge base with weekly auto-sync, API access, voice input and full chatbot styling. Agents can run actions and workflows during a conversation, and the model list covers OpenAI, Anthropic, Google, Mistral, xAI, DeepSeek and Z.ai. Chatling's plan table lists web, WhatsApp, Instagram, Messenger, Telegram and API as channels, and integrations with Google Sheets, Cal.com, Zapier, Zendesk, Zoho, HubSpot, Slack and Airtable, though not every one is on every plan. Add-ons are cheap: $3 per extra agent and $10 per 1,000 extra credits. The catches are a $35 a month fee to remove the Chatling mark, and a credit system where flagship models use more of the allowance.

Dante AI is the most direct replacement for teams that use Chatbase as a website support bot. You point it at your site, Google Drive or Notion, and it answers visitors in website chat by text and voice. The free plan gives one agent, 100 messages a month and 150,000 characters of knowledge with no card, which is enough to test answer quality on real content before paying. Starter costs $40 a month, or $33.33 billed yearly, and raises the limits to 2,000 messages, 2 seats and 25M characters, with every AI model and 9,000+ apps through Zapier. The features that make it a lead tool sit one tier higher: Advanced adds 3 agents, 8,000 messages, a person taking over in the inbox, exported lead lists, removal of the Dante mark and a phone number you can rent. The limits to note are that credits reset monthly without rollover and the API only arrives on Pro.

Botsonic is the cheapest way into a paid docs bot on this list. Starter is $16 a month billed annually, or $19 monthly, with 1 chatbot, 1 team member and 1,000 messages a month, and it trains on uploaded files and sitemaps of up to 5,000 URLs. Unlike many entry plans, it already lists WhatsApp, Facebook Messenger, Telegram, Zapier, WordPress, Google Tag Manager and Google Drive. Professional at $41 a month billed annually adds agentic actions, 3,000 messages, Slack, Google Chat, Calendly and Notion. Advanced at $249 brings agentic workflows, 12,000 messages and API access. The add-on list is where costs climb: $49 a month to remove branding, $49 for API access below Advanced, $25 per extra team member and $199 for ticket and live agent handoff to Zendesk. For a single site that needs a branded bot on a small budget, the entry plan is hard to beat.

DocsBot is built for teams whose bot needs to read a lot of documentation. The Personal plan at $49 a month covers one bot with 5k source pages and a 5k monthly AI credit limit, plus 3 actions per bot, remote MCP connections, lead forms, scheduling tools, Zapier, Slack and Messenger, WhatsApp and Telegram. Standard at $149 a month moves to 3 bots, 15k pages, 5 team users and native CRM lead delivery, with conversation and question analytics that show what your docs fail to answer. DocsBot says it uses an agentic RAG pipeline and answers in over 100 languages, even from English-only docs. Support teams can import chat logs or tickets from Zendesk, Intercom, Freshdesk and Help Scout to train it. Annual billing gives two months free. The tradeoffs: the free plan is for personal use with only 100 credits, and paid plans have a money-back guarantee rather than a free trial.

Botpress suits Chatbase users who have hit the limits of a simple trained bot and want to build real logic. It combines a visual studio, a natural language builder, knowledge bases, tables and its own help desk, Botpress Desk, with escalation and handoff. The free plan includes 100 conversations, 3 seats and 3 AI agents, which is enough to prototype. Plus is $150 a month billed annually for 250 conversations, $25 of AI usage, unlimited agents, white-label webchat and a Help Center on your own domain, and each conversation includes $0.10 of LLM cost covered by Botpress. Team at $750 a month billed annually raises that to 1,500 conversations with unlimited seats, routing and team analytics. Integrations listed include Intercom, Zendesk, HubSpot and Salesforce, and channels include webchat and WhatsApp. The costs are a big step from free to Plus, $65 per 100 extra conversations, and voice only on Enterprise.

SiteGPT is a focused website chatbot for teams that mostly want answers drawn from their own pages. Starter is $39 a month billed yearly, or $59 monthly, for 1 chatbot, up to 4k messages a month and up to 1,000 pages of training content, where a page is 2,500 cleaned characters. Growth at $79 billed yearly adds a second chatbot, 10,000 pages, 4 members, API access, an iOS app and monthly auto-refresh. SiteGPT integrates with Google Chat, Messenger, Slack, Crisp, Freshdesk Messaging and Zoho SalesIQ, and it can install as the AI agent inside Zendesk Messaging so it answers first and hands over with history. WhatsApp and AI email support are add-ons priced per number or inbox. Two points to check: message counts depend on the model, since GPT-4.1 messages cost 10 times GPT-4.1-mini, and the 7-day trial needs a card.

Intercom Fin is the choice when the chatbot is really part of a support operation. Fin learns your support content, answers across channels and hands conversations to agents in the inbox. Pricing has two parts: help desk seats, from $29 per seat a month billed annually on Essential (new customers pay $19), and $0.99 per outcome for Fin. An outcome is charged once per conversation when Fin resolves it or completes a procedure, including handoffs, and Intercom says you never pay if Fin cannot answer. Teams already on Salesforce, HubSpot or Freshdesk can run Fin on top of that helpdesk through sales, with a minimum monthly commitment and no seat fees. WhatsApp and SMS are billed per message, and Fin Voice costs $1.99 per voice outcome. For a busy queue that billing can be cheaper than more staff, but for a small site with many simple questions a flat Chatbase-style plan usually costs less.

Stammer.ai is aimed at agencies rather than single businesses, and that is its main difference from Chatbase. Standard is $49 a month with 500 AI replies and 120 voice minutes, at least one chat agent and one voice agent, web chat, Facebook, Instagram, WhatsApp and API, live chat handoff, lead collection and calendar booking. Pro at $99 a month is the agency plan: 5 chat and 5 voice agents, full white labeling with your own domain, logo and colors, resale of replies, minutes and agents at prices you set, MCP support, bring-your-own LLM keys and white-label API endpoints. Clients get sub-account wallets so they can pay you directly for usage. Extra agents are $10 a month and 1M more knowledge characters $5. The model is usage-heavy: replies and minutes beyond the plan are billed per message or minute, so margins depend on how you price for clients.

Tidio Lyro fits teams that want an AI agent and a live chat tool from the same vendor. Lyro answers from your knowledge base in a style you set and hands the chat to a person when needed. Tidio's Starter plan is $24.17 a month billed annually with 100 billable conversations, live chat and ticketing, but it includes only 50 Lyro conversations as a one-off. For ongoing AI answers, Lyro is sold as an add-on or as a stand-alone product from $32.50 a month for 50 Lyro conversations, and the stand-alone version can run inside Zendesk, Salesforce or another help desk. Tidio says its customers average a 75% Lyro resolution rate, and Premium adds a guaranteed 50% resolution rate with pay-per-resolution billing. The weak point compared with Chatbase is the pricing model: three separate meters for human conversations, Lyro conversations and Flows visitors make bills harder to predict as volume grows.

CustomGPT.ai takes the Chatbase approach to a larger scale of content. Standard costs $99 a month, or $89 billed annually, and includes 10 agents, 5,000 documents per agent, 60M words of storage, 3 team members and RAG API access. That makes it a fit for organizations running several assistants, for example one per department or product, over large document sets. Content can auto-sync from sources such as Wix, YouTube, Notion, Google Drive, Zapier and the HubSpot and Zendesk knowledge bases, and agents can be deployed to Slack. Multi-language support covers 90+ languages on every plan, and education and nonprofit pricing is offered. The tradeoff is cost per answer: Standard includes 1,000 queries a month and 2,500 extra queries cost $375 a month, so a busy public website will outgrow it fast. Premium at $449 billed annually raises limits to 25 agents and 5,000 queries.
