FastBots Alternatives (2026): 9 AI Chatbots Compared on Credits, Models, Handoff and White-Label

Short answer: FastBots is one of the cheaper ways to run a website chatbot on standard AI models: $39 a month buys 2,000 message credits, and its default model uses 1 credit per reply. An alternative fits better in four cases. For a free plan that keeps running, look at Chatling or Tidio. For premium models at a low multiplier, Chatbase charges 2 credits for Claude 5.5 Sonnet where FastBots charges 10 for Claude 5 Sonnet. If a helpdesk must take over, look at SiteGPT inside Zendesk, DocsBot with ticket escalation, or Weav with its own inbox. If you resell to clients, Stammer white-labels from $99 a month, against $399 for FastBots Reseller. Updated November 9, 2026.

How we checked: plans, limits and unit prices come from each vendor's own pricing page or help docs, read November 9, 2026. Where a page does not state something, we say "Not stated". We did not test these chatbots hands-on, so this guide compares price, limits and features, not answer quality.

FastBots builds a chatbot trained on your website, documents, Google Sheets and YouTube videos, and puts it on your site, WhatsApp, Messenger, Instagram, Telegram and Slack. Its pricing page lists four plans, with about 17% off on annual billing. Credits are shared across all bots on the account.

• Trial, not a free plan. New accounts get a 14-day trial with 1 chatbot and a one-time 200 message credits, no card required. When it ends the chatbot is taken offline until you upgrade. Only accounts that were already on the old Free plan go back to it.
• Models. FastBots offers models from OpenAI, Anthropic and Google. The default, GPT-6 Luna, and the other standard models (GPT-4o mini, GPT-4.1 mini, GPT-5.6 Luna, Claude 4.5 Haiku, Gemini 3.6 Flash, Gemini 3.8 Flash) use 1 credit per reply. GPT-4o, GPT-4.1, GPT-5.2 and Gemini 3.1 Pro use 5. GPT-5.6 Terra, GPT-6 Sol, Claude 4.5 Sonnet and Claude 5 Sonnet use 10.
• Voice bots. Visitors can talk to the bot in your website widget, voice only or voice and text, from the voice chatbot page. Voice is on Business and up, plus the trial, and costs 50 credits a minute, billed by the second. It is not a phone answering service; other channels stay text.
• Add-ons. 1,000 extra credits are $10 a month, an extra chatbot $10, branding removal $29 on eligible plans, and a custom domain $49.

Where FastBots is strong is the price per reply on standard models. Essential works out to about 2 cents per 1-credit reply ($39 for 2,000), and extra credits are $10 per 1,000. Chatbase Hobby is $40 for 700 credits, about 5.7 cents per 1-credit reply, and its top-ups are $40 per 1,000. Its tool page on Stork is FastBots.

• Credit limits. Essential has 2,000 credits a month and there is no ongoing free plan. When the trial ends, the bot goes offline.
• Model cost multipliers. A 10-credit model turns Essential's 2,000 credits into 200 replies, about 19.5 cents each. Voice uses the same pool: Business's 5,000 credits cover 100 minutes of talk if nothing else uses them.
• Helpdesk handoff. Human takeover is FastBots' own live chat, on Business ($89) and up. Its integrations page lists HubSpot, Zapier and Make but no native Zendesk, Freshdesk or Intercom connection.
• White-label. Removing the FastBots badge needs Premium ($199) or a $29 add-on on eligible plans, and full white-label with client logins needs Reseller ($399).

Chatling: a free plan that stays on

Chatling has a free plan with 200 AI credits a month, 1 agent and 500,000 knowledge base characters, renewed monthly rather than once. Its pricing page lists Starter at $25 a month ($21 annual) for 1,750 credits and 2 agents, Growth at $75 ($63) for 6,000, and Scale at $295 ($246) for 35,000. Extra credits are $10 per 1,000, the same as FastBots.

Not for: cutting model costs. Chatling also multiplies: GPT-6 Luna and Claude Haiku 5.5 are 1 credit, Claude Sonnet 5.5 is 5, Claude Opus 5.5 is 14 and GPT-6 Astra 25. The free plan only has its base models, and Starter's 1,750 credits are fewer than FastBots Essential's 2,000.

Tidio: pay per conversation, not per reply

Tidio counts conversations, so a long chat does not drain a credit pool. Its pricing page shows a free plan with 50 billable conversations a month and 50 Lyro AI conversations once. Paid plans start at $24.17 a month for 100 conversations, and Lyro AI starts at $32.50 a month for 50 AI conversations. Human live chat is part of the product.

Not for: choosing your model, or high AI volume on a small budget. Tidio does not state which model Lyro uses, and 50 AI conversations for $32.50 is a small allowance next to FastBots' 2,000 replies.

Botpress: conversations plus AI usage at cost

Botpress counts any exchange with at least two user messages in a month as one conversation, according to its pricing page. Free gives 100 conversations. Plus is $150 a month for 250 conversations and $25 of AI usage, with packs of 100 more for $65. For voice calls, 3 minutes counts as one conversation. See its Stork listing.

Not for: a quick website bot on a small budget. Botpress is a builder for bots with logic and integrations, and $150 is nearly four times FastBots Essential.

CustomGPT.ai: for large document collections

CustomGPT.ai is built around big knowledge bases. Its pricing page lists Standard at $99 a month ($89 annual) with 1,000 queries, 10 agents and 5,000 documents per agent, and Premium at $499 ($449) with 5,000 queries. Both start with a 7-day trial that needs a card. See its Stork listing.

Not for: price per answer or model choice. 1,000 queries for $99 costs far more per reply than FastBots, and the AI model selector is not on the Standard plan.

Chatbase: low multipliers on top models

Chatbase's FAQ charges 2 credits per reply for most named models, including Claude 5.5 Sonnet, GPT-6.1 Sol, GPT-5.6 Terra and Gemini 3.1 Pro, 4 for GPT-5.5 and 5 for Claude 5.5 Opus. Other models are 1 credit. Its pricing page lists Hobby at $40 a month ($32 annual) for 700 credits, Basic at $150 ($120) for 4,000 and Business at $500 ($400) for 15,000, with a trial but no free plan.

At 2 credits, Hobby gives 350 Claude 5.5 Sonnet replies; FastBots Essential gives 200 Claude 5 Sonnet replies at 10 credits. Not for: high volume on cheap models, where FastBots gives about three times the replies per dollar, or anyone who wants handoff on the entry plan. Our Chatbase alternatives guide covers its limits in detail.

DocsBot: bring your own OpenAI key

DocsBot charges AI credits with model multipliers from 1x (GPT-6 Luna) through 5x (GPT-6.1 Terra) and 10x (GPT-6.1 Sol) to 50x (GPT-6 Astra). The way out is your own OpenAI key: its pricing page says that makes every model bill at 1x. Free has 100 credits a month, Personal is $49 for 5,000 credits, Standard $149 for 15,000, and Business $499 for 60,000. Annual billing gives two months free.

Not for: a cheap website bot with handoff. Personal at $49 has 1 bot, and escalation tickets and helpdesk integrations start on Standard at $149. See its Stork listing.

SiteGPT: an AI agent inside Zendesk

SiteGPT counts messages by model: its pricing page gives Starter 4,000 GPT-4.1-mini messages or 400 GPT-4.1 messages a month, for $59 ($39 annual). Growth at $129 ($79) adds an iOS live inbox with one-tap takeover and integrations such as Crisp, Freshdesk Messaging and Zoho SalesIQ. Scale at $429 ($259) installs SiteGPT as the AI agent inside Zendesk Messaging, handing chats to your human agents with history. Every plan starts with a 7-day trial that needs a card.

Not for: model choice or a small budget. The pricing page names only GPT-4.1 and GPT-4.1 mini, and the Zendesk agent costs more than FastBots Premium.

DocsBot: ticket escalation and helpdesk training

On Standard ($149 a month), DocsBot adds escalation ticket creation, a Help Scout integration and realtime voice agents. Its helpdesk page has setup guides for Help Scout, Freshdesk, Zoho Desk, Zendesk, Salesforce Service Cloud, FreeScout and Teamwork Desk, and its FAQ says it can import past tickets from Zendesk, Intercom, Freshdesk and Help Scout to train on.

Not for: a team without a helpdesk. If you just need someone to take over a chat, FastBots Business has that for $89.

Weav: chatbot plus a shared inbox

Weav is AI customer support software with a website chatbot and a unified inbox for chat, email and third-party messages, with handoff to a human from its Plus plan. Its pricing page lists Lite free with 20 AI messages a month, Plus at $29 for 500, Pro at $119 for 5,000 and Max at $359 for 20,000.

Not for: volume on a budget. FastBots Essential has four times Plus's messages for $10 more, though without live chat; Weav's Pro has the same 5,000 messages as FastBots Business for $30 more.

Stammer: white-label chat and phone agents

Stammer is built for agencies. Its pricing page lists Standard at $49 a month with 500 AI replies and 120 voice minutes, extra replies at $0.01 and extra minutes at $0.10. Pro at $99 is fully white-labeled with your own domain, 5 chat and 5 voice agents, resale of usage at your own prices, and your own OpenAI, Anthropic or other LLM keys. Its voice agents answer and make phone calls, which FastBots' website voice bot does not. Yearly billing saves 20%; trials need a card.

Not for: a single business that wants included volume. Stammer's model is a prepaid usage wallet, while FastBots Reseller bundles 30,000 credits and 30 chatbots in its $399.

Other white-label routes: Botpress sells webchat white-labelling as a $40-a-month add-on, DocsBot's Business plan ($499) has unbranded widgets and per-bot roles for reselling, and Chatbase charges $99 a month to remove its branding.

• You run a website bot on standard models and want the most replies per dollar: $39 for 2,000 replies, with extra credits at $10 per 1,000.
• You want one tool for website, WhatsApp, Messenger, Instagram and Telegram on the entry plan.
• You want voice in your website widget without a separate voice product, and Business's 5,000 credits cover your mix of chat and talk minutes.
• You need human takeover but not a full helpdesk: Business at $89 includes live chat.

• Your bot must stay on for free: Chatling (200 credits a month) or Tidio (conversations).
• You use Claude Sonnet or other premium models a lot: Chatbase at 2 credits, or DocsBot with your own OpenAI key at 1x.
• Your team lives in Zendesk or Help Scout: SiteGPT Scale for Zendesk, DocsBot Standard for Help Scout and ticket escalation.
• You want a chatbot and an inbox in one product: Weav or Tidio.
• You are an agency: Stammer Pro at $99 if you want phone agents and your own keys; FastBots Reseller at $399 if you want 30,000 included credits.
• Very large document sets: CustomGPT.ai.

Before you switch, count your volume the way each tool counts it: replies times the model multiplier for FastBots, Chatbase, Chatling and DocsBot, conversations for Tidio and Botpress, and queries for CustomGPT.ai.

Stammer, if you want a lower entry price: its $99 Pro plan is fully white-labeled, lets you use your own LLM keys and includes phone voice agents. FastBots Reseller at $399 is the better fit if you want 30,000 included credits, 30 chatbots and up to 5 brands in one plan.
