What our research says

Chatbase

The fastest route from a folder of help docs to a working support widget, and priced accordingly once real traffic arrives. Credits are the whole story: 700 messages a month on Hobby ($40, or $32 billed yearly) is a small site's volume, and the plans that carry real traffic cost $150 and $500 a month. There is no free plan to fall back on, so budget from expected conversations, not from the feature grid.

Pros

  • Crawl-and-embed setup produces a usable widget in an afternoon with no retrieval plumbing to write
  • Actions and human handoff mean it degrades into a ticket rather than a dead end
  • Every paid plan carries a 7-day trial, and the yearly toggle takes 20% off

Cons

  • The free plan is gone, so evaluation is limited to a 7-day trial
  • API access is gated to Standard at $150/month ($120 billed yearly), several times the entry price
  • Overage at $40 per 1,000 credits is steep next to the in-plan rate on Pro
  • Each plan includes a single agent; more cost $300 per agent a year, and removing branding $1,188 a year

FastBots

FastBots is the pragmatic end of the bot-builder market: crawl a site, get a working bot, drop it on six messaging channels. Letting you pick the underlying model across three vendors is genuinely useful and not common at this price. The message-credit ceilings are the thing to size carefully, because 2,000 credits disappears fast on a busy site and the overflow add-ons are priced per block.

Pros

  • Choose the underlying model across OpenAI, Anthropic and Google rather than being locked to one
  • One bot serves web, WhatsApp, Telegram, Messenger, Instagram, Slack and email
  • Automatic re-crawling and retraining keeps the bot current as the source site changes
  • Zapier AI Actions let a bot book appointments or check orders mid-chat, and the trial needs no card

Cons

  • Advertised prices assume annual billing - month-to-month Essential is $39, not $33
  • Message credits are the real constraint, and premium models burn 5 or 10 credits per reply
  • Removing FastBots branding is a $29/month add-on, nearly doubling the entry plan
  • The free plan is gone for new accounts; after the 14-day trial the bot goes offline until you pay

Which one fits

Choose Chatbase if you need

  • SaaS and ecommerce teams deflecting repeat questions from existing documentation
  • Solo founders who need a support presence before they can hire one
  • Agencies standing up a branded bot per client, provided each client funds its own agent slot

Choose FastBots if you need

  • Small businesses turning an existing website into a support bot quickly
  • Teams that need the same bot on WhatsApp, Telegram and their site
  • Agencies reselling bots under the reseller tier
