FastBots.ai vs SiteSpeakAI: which support chatbot should you build on?

Both of these tools do the same core job: point them at your website, docs, and PDFs and they build a chatbot that answers customer questions around the clock. The interesting part is where they diverge. FastBots.ai leans toward businesses that want their bot living inside WhatsApp, Instagram, and Telegram from day one. SiteSpeakAI leans toward a cheaper, more agent-like start, with a real free plan and a bot that does more than talk. If you just want the short version: SiteSpeakAI is the easier place to begin, FastBots is the easier place to scale customer messaging.

What they agree on

The overlap is large, which is why they show up as alternatives to each other so often. Both train on your website URLs, uploaded documents, and video content, and both let visitors chat in roughly 95 languages. Both give you a widget you drop onto any site, capture leads, hand a conversation off to a human when the bot is out of its depth, and report on what people are asking. Both also let you pick which underlying model answers — each supports OpenAI, Anthropic, and Google models rather than locking you to one.

So the decision isn't about which one can build a support bot. Both can. It's about the starting price, where the bot can be deployed, and how far it goes beyond answering.

FastBots.ai: built around channels and message volume

FastBots frames itself as a three-step build: import your data (websites, PDF, DOCX, TXT, CSV, XLS, Google Sheets, or YouTube videos), customise the look, then embed. Setup is genuinely quick and needs no code.

Its clearest advantage is deployment. Even the entry Essential plan lists integrations for WhatsApp, Messenger, Instagram, Telegram, Slack, and WordPress alongside Zapier and Make, so you can put the same bot in front of customers wherever they already message you without paying for a higher tier. The other lever FastBots pulls is agentic actions through Zapier: the bot can call thousands of apps mid-chat to check an order, book an appointment, or send an email.

Pricing runs on shared message credits, where a reply from a standard model costs one credit and an advanced model costs five to ten. Essential is $39 a month ($33 on annual billing) for two chatbots, 2,000 message credits, and 2,500 crawl pages of training content. Business at $89 ($75 annual) raises that to five bots and 5,000 credits and adds live chat takeover, automatic retraining, chat translation, and email auto-replies. Premium ($199) lets you remove FastBots branding, and a $399 Reseller tier white-labels the whole thing for agencies. There's a no-credit-card free trial, but no permanent free plan on the current pricing page.

SiteSpeakAI: a free tier and an agent that acts

SiteSpeakAI describes itself as "an AI agent for your site that answers and acts," and the second half of that sentence is the point. Beyond answering, it captures leads, books meetings, looks up orders, and escalates the conversations it shouldn't handle. It advertises being live in one line of code and trusted by more than 1,000 businesses.

Two things stand out for smaller teams. First, there's a genuine free plan: $0 for 30 message credits a month, one agent, and 10 training sources — enough to build a bot and see it work before paying. Second, the paid entry point is lower. Starter is $29 a month ($24 annual) for 1,000 credits, one agent, 200 training sources, lead capture, and the option to remove the "Powered by" badge.

The developer-facing features arrive on the $79 Pro plan: all AI models plus bring-your-own-key, WhatsApp, Google Chat and HubSpot, and API and MCP server access. That MCP support is worth flagging if you want the agent to plug into other AI tooling — FastBots doesn't advertise it. Higher up, Growth ($249) adds 15 actions per agent, a custom domain, and daily source syncing, and Business ($499) unlocks unlimited agents with dedicated onboarding. Extra credits are $25 per 1,000 if you outgrow a plan mid-month.

The pricing picture side by side

The tiers don't line up one-to-one, so compare what the first paid plan actually includes rather than the headline number.

	FastBots.ai	SiteSpeakAI
Free plan	Trial only, no card	Yes — 30 credits/mo, 1 agent
First paid tier	Essential $39/mo ($33 annual)	Starter $29/mo ($24 annual)
Entry-tier credits	2,000 message credits	1,000 message credits
Bots on entry tier	2	1
Major messaging channels	From Essential (entry)	From Pro ($79)
Bring-your-own API key	Not advertised	Yes, on Pro
MCP server access	No	Yes, on Pro
White-label / reseller	Reseller tier ($399)	Agency plans from $399

The honest read: FastBots gives you more messages and channels lower down, SiteSpeakAI gives you a free on-ramp and a cheaper first paid step. Which is "cheaper" for you depends entirely on your reply volume and whether you need WhatsApp on day one.

Which one fits you

Pick FastBots.ai if your customers reach you across several channels and you want the bot in WhatsApp, Instagram, and Telegram without upgrading, if you expect high message volume and want more credits per dollar at the entry tier, or if you're an agency that wants to resell a white-labeled bot with message credits pooled across client bots (SiteSpeakAI also runs agency white-label plans from the same $399 starting point, so compare both).

Pick SiteSpeakAI if you want to try a working bot for free before committing, if the lowest possible paid entry matters, or if you care about the agent actually doing things — booking, order lookups, MCP and API access, and bring-your-own-key — more than about maximum channel coverage.

For a lot of small businesses it comes down to a simple test. If most of your support already happens over messaging apps, FastBots removes a paywall you'd hit early. If your support lives on your own site and you'd rather validate the idea at no cost first, SiteSpeakAI is the gentler start.

FAQ

Can both bots hand off to a human agent? Yes. FastBots includes live chat takeover from its Business plan, and SiteSpeakAI's escalate-to-human handoff starts on its Pro plan, though the live chat widget and inbox are available even on its free plan.

Do I need to know how to code? No. Both are no-code: you train on your content and embed a snippet. SiteSpeakAI advertises going live in one line of code, and FastBots pitches a setup in under five minutes.

Can I choose the AI model? Both let you pick among OpenAI, Anthropic, and Google models. SiteSpeakAI additionally supports bringing your own API key on its Pro plan.
