9 Best Facebook Messenger Chatbot Builders of 2026

ManyChat is the most complete Messenger automation tool we compared for social-first businesses. It handles the entry points that drive most Messenger traffic, replying automatically to post comments, DMs and Story mentions, and it runs the same flows on Instagram, WhatsApp, TikTok and Telegram. Quick Automations cover common jobs such as welcome messages, FAQs, giveaways and capturing an email or phone number from a comment, and a custom flow builder handles the rest. Pricing is by active contacts: the free plan covers 25 people a month with 2 channels and ManyChat branding, Essential costs $14 per month billed annually for 250 contacts and removes branding, and Pro at $29 adds broadcasting, a third channel and AI features. The tradeoff is that the features many Messenger marketers want, campaigns and AI replies, start on Pro, and bills grow with contact volume once ads start bringing in new people.

Chatfuel has moved from a classic flow builder to an AI-first platform, and its Messenger page describes the full lead path: connect a Facebook Page, choose a trigger such as a Page message, comment or ad response, then let a no-code flow or AI agent answer questions, capture contact details, segment leads and hand sales-ready chats to a person. It also replies to Reels and post comments and can send lead events back to Meta through the Conversions API. Pricing is a plan plus usage. Business S costs $18 per month billed yearly and includes $20 of AI credits a month; larger Business and Agency tiers include more credits, and Chatfuel publishes a calculator with per-reply costs. The catch is that there is no permanent free plan, AI replies stop when credits run out, and heavy WhatsApp use adds a 10% markup on Meta's template fees.

SendPulse is a wider marketing suite whose Messenger chatbot builder holds up well on its own. You connect a Facebook Page from the Messenger section, build flows from ready-made elements and templates, and set keyword auto-replies. Bots can start from comments on your posts, send bulk or segmented Messenger campaigns, take payments in chat and sync data to the built-in CRM or Google Sheets. Its statistics follow ads that click to Messenger through to conversations, leads and purchases, which helps teams that run Messenger ads. The free plan is the most generous we found for Messenger, with 3 chatbots, up to 500 subscribers and 10,000 messages a month. The page we fetched did not show paid prices in US dollars, so the Pro price is pending, and chat support on the free plan only runs for 30 days after signup.

respond.io is the heavyweight here, aimed at businesses that earn revenue from high-volume conversations across Messenger and other channels. Several Facebook Pages or brands can sit in one workspace, each as its own channel with separate routing, and leads from click-to-Messenger ads, QR codes and chat plugins are tracked from first message to sale. AI Agents answer FAQs, qualify leads and recommend products, while managers can supervise or step into any chat. It also sends Messenger campaigns and transactional notifications and syncs with HubSpot, Salesforce, Zoho or Shopify. respond.io itself says a single Page with occasional messages is fine in Meta's native inbox, and its price reflects the target market: Starter costs $79 per month billed yearly, Growth $159 and Advanced $279, with a 7-day trial and no free plan.

Spur is built for online stores that take orders and questions over chat, and Messenger is one of its four core channels next to WhatsApp, Instagram and website live chat. All chats land in a shared inbox, automation flows run on Facebook and Instagram, and an AI agent answers questions using monthly AI credits. Click-to-DM ad automation suits brands that buy social ads. The entry plan, AI Acquire, costs $12 per month billed annually and connects one Facebook, Instagram, WhatsApp and live chat channel with 1 seat, 3 automation flows and 100 AI credits. AI Start at $31 adds Shopify integration, WhatsApp automation, 25 flows and 700 credits. Spur is an official Meta Business Partner. The limits on the entry plan are tight, so most stores with steady Messenger volume will end up on AI Start.

UChat is a builder's tool: one bot, designed once in a drag-and-drop editor, can run on Messenger, WhatsApp, Instagram, web chat, Telegram, Viber, SMS, voice and more than a dozen channels in total. AI agents handle sales, support and lead qualification, and complex questions transfer to live agents. Advanced users get JavaScript nodes, external requests and mini apps, which gives it more depth than most social-first tools. The free plan covers 1 bot and 200 bot users, Business is listed at $15 per month with 1 bot, 1,000 bot users and 5 members, and a $199 Partner plan adds full white label for agencies that resell bots. The pricing page shows $29 on its other billing option, so check which term you choose. The tradeoffs are that each extra bot is an add-on and that the power features take time to learn.

Tidio is a support tool first, and Messenger is one of the channels it pulls into a single panel with website live chat, Instagram, WhatsApp and email. Its Messenger integration runs automated Flows that answer shipping and order status questions, suggest products when an item is out of stock, collect emails or phone numbers and run carousel surveys. The Lyro AI Agent adds knowledge-based answers with human handoff, and teammates can transfer chats across desktop and mobile apps. Pricing is modular: there is a free plan, the Starter customer service plan costs $24.17 per month billed annually for 100 billable conversations, Lyro starts at $32.50 and Flows at $24.17 as separate products. That suits a store that mainly needs support, but Messenger marketers will find fewer broadcast and comment tools than in ManyChat or SendPulse, and stacking modules raises the total.

Flow XO is a straightforward chatbot builder that has supported Messenger for years alongside WhatsApp, Telegram, Slack, web and SMS. Bots greet visitors, answer simple questions, gather and validate information, pre-filter leads and take payments, and hand over to live chat with the conversation context in place. The Standard plan costs $25 per month and includes all features: 5,000 interactions, 15 bots or active flows, 5 team members, AI assistants, a knowledge base and 250 AI credits, with low-cost add-ons and a 10% discount for annual payment. A Free Forever plan gives 100 interactions and 5 bots each month. It lacks the comment triggers, ad tracking and broadcast depth that social-first tools offer, so it suits lead capture and support bots more than Messenger marketing.

Landbot is best known for conversational web forms and WhatsApp bots, and Messenger is available as a channel from its Starter plan. Its visual builder and templates make it one of the easiest tools here for marketers, and paid plans add AI agents, A/B tests, human takeover in a shared inbox, and lead qualification and routing. Plans count chats rather than contacts, with a published allowance of AI chats on each tier, and Professional adds 3 seats, HubSpot, Airtable and webhook integrations and removes Landbot branding. The free plan gives 100 chats a month but only on the web. The pricing page we fetched showed euros, so the USD price is pending. Landbot has few Messenger-specific tools such as comment triggers or Messenger broadcasts, so it fits teams whose main bot lives on the website.
