How we compiled this
Re-verified 2026-06-15 via WebFetch on official pricing pages plus cross-checks. Chatbase (chatbase.co/pricing), Tidio (tidio.com/pricing/), Landbot (landbot.io/pricing), Wonderchat (wonderchat.io/pricing), CustomGPT (customgpt.ai/pricing/) fetched directly and confirmed. Voiceflow's official pricing page (voiceflow.com/pricing) no longer displays dollar amounts (demo/quote CTAs only); Pro $60 and Business $150 per-editor pricing confirmed via checkthat.ai and costbench.com and Voiceflow's own credits docs, so priced-plan source URLs point to checkthat.ai which actually shows the figures. Botpress (botpress.com/pricing) returned 403; verified via costbench.com and lindy.ai: Plus $150/mo, Team $750/mo (the draft's $189/$939 were wrong), and AI usage is billed separately as +AI Spend (NOT bundled). ManyChat (manychat.com/pricing) returned 403; March 2026 restructure produced Free/Essential/Pro/Business (verified via flowgent.ai and costbench.com); the draft's Pro $15 and a custom 'Elite' tier were corrected (Pro starts $29; Business is a published $69 plan; Essential $14 added). Chatfuel's official live page (chatfuel.com/pricing) shows a SINGLE $69/month 'AI Business Assistant' plan; the draft's 'Fuely Super/Max' contact-tier ladder appears only on third-party aggregators and is not on the official page, so it was removed. Compliance claimed only where the vendor states it. accessedAt 2026-06-15.
