The main differences are pricing, channel support, and model selection. Chatbase's entry paid tier is $32/month annual ($40/month billed monthly) for the Hobby plan — 500 message credits/month. Standard is $120/month. saavos's first paid tier is $9/month (Solo) for 1,000 messages/month. Chatbase offers model selection including GPT-5 variants and WhatsApp/Instagram integrations live as of 2026; saavos is website-only and runs Claude natively. For indie SaaS needing basic FAQ deflection from a website under $25/month, saavos covers the job. For multi-channel or model flexibility, Chatbase has more. Pricing confirmed from chatbase.co/pricing, 2026-05-19.
No longer. FastBots Essential doubled from $16-19/month to $39/month in early 2026, making saavos Solo ($9/month) the cheaper entry-paid option. FastBots includes live agent takeover from its entry tier, which saavos doesn't offer. Both are cheaper than Chatbase's $32/month annual Hobby tier ($40/month billed monthly). Check current FastBots pricing before committing — they've adjusted pricing once already this year.
Depends on what you need. For FAQ deflection from a website with a budget under $25/month, saavos at $9/month is the only entry-paid option in this group after FastBots raised its price. For multi-channel (WhatsApp, Instagram), Chatbase at $32/month annual Hobby (or $120/month Standard for full channel access) is the more capable product. For live agent takeover at the entry tier, FastBots. All three have no-card previews — train on your docs with the no-card preview before committing to a paid plan.
Yes. Chatbase added WhatsApp, Instagram, and Messenger integrations in early 2026. This is a real differentiator versus saavos and FastBots, which are website-widget-only products. If you need WhatsApp or social-channel chatbots, Chatbase is the only one of these three that has those live.
For a simple site — documentation page, landing page, basic FAQ — all three products in this comparison can be live in 5-20 minutes. Complexity increases with site size, non-standard robots.txt, or multi-source training. The embed itself (one script tag) takes 60 seconds once the bot is configured. The first 48 hours post-launch are for tuning: check conversation logs, find the misses, update sources.
saavos runs Claude (Anthropic): a faster Claude model on the no-card preview, frontier Claude on Solo and above. Chatbase offers model selection — GPT-4o, GPT-4o mini, Claude Sonnet, and GPT-5 variants — at the account level. FastBots runs OpenAI GPT-4 class models. If you have a strong preference for GPT-5 or want to switch models per use case, Chatbase is the only one of these three with that flexibility built in.
Yes. saavos, Chatbase, and FastBots all offer evaluation paths before paid rollout. The saavos no-card preview is enough to test training quality before committing to a paid plan. saavos preview uses a faster Claude model. Chatbase free uses GPT-4o mini. All three require no credit card to start.
