Constructor de Chatbots de Facebook Gratis: 8 Plataformas que Te Permiten Construir Sin Pagar en 2026

Busca un constructor de chatbots gratuito de Facebook en 2026 y te encuentras con el mismo problema una y otra vez: la mitad de los listados comparan planes realmente gratuitos, la otra mitad están incluyendo pruebas, y algunos todavía recomiendan productos que apenas se parecen a sus antiguas herramientas de Messenger.

Revisé las páginas de precios públicos actuales, documentos de ayuda y notas de planes para los ocho nombres que la gente sigue comparando con más frecuencia para la automatización de Facebook Messenger: MessengerBot, ManyChat, Chatfuel, MobileMonkey, Botsify, Landbot, Tidio y SendPulse. Luego los clasifiqué según un estándar que importa más que el titular de marketing: cuánto puedes hacer realmente en la configuración útil del bot de Facebook antes de que el muro de pago cambie tus decisiones.

Esa distinción es importante. Una plataforma puede ser un software excelente y aún así ser una respuesta débil a “constructor de chatbots gratuito de Facebook.” Otra puede ofrecer un nivel gratuito para siempre que parece generoso hasta que te das cuenta de que Messenger en sí está bloqueado detrás de un plan de pago. Una tercera puede ser técnicamente gratuita, pero tan limitada que solo funciona como un sandbox.

Los detalles de precios y planes gratuitos a continuación reflejan las páginas de proveedores públicos revisadas el 10 de abril de 2026. Estoy usando USD en todo momento porque esa es la referencia de precios comunes más clara en el mercado de EE. UU. y Reino Unido.

Lo que “Gratis” realmente significa en los constructores de chatbots en 2026

La palabra gratuitas esconde al menos cuatro ofertas diferentes en este mercado.

Gratis para siempre con uso real de Messenger es el mejor escenario posible. Eso significa que puedes conectar una Página de Facebook, construir un bot y mantenerlo funcionando indefinidamente siempre que te mantengas dentro de los límites de contacto, mensaje o automatización. En esta comparación, ManyChat y SendPulse se acercan más a esa definición.

Gratis para siempre, pero no realmente para Messenger es la segunda categoría. Landbot y Tidio te dan un verdadero punto de entrada sin costo, pero la experiencia gratuita es más útil para experimentar, chat en el sitio web o aprender a usar el constructor que para ejecutar un bot serio de Página de Facebook.

Prueba gratuita o asignación inicial es la tercera categoría. Chatfuel, MessengerBot y Botsify te permiten probar la plataforma sin pagar por adelantado, pero eso no es lo mismo que un nivel operativo gratuito para siempre. La página actual de Facebook de Chatfuel promociona una prueba gratuita y una pequeña asignación de conversaciones gratuitas. MessengerBot publicita públicamente un registro para la prueba gratuita, pero la página de precios en sí comienza con planes de pago. Botsify también se basa en el acceso de prueba antes de que sus planes de constructor de pago entren en acción.

Plan gratuito heredado, desajuste de producto actual es la cuarta categoría. MobileMonkey es el mejor ejemplo. Los antiguos documentos de ayuda aún hacen referencia a un plan gratuito y límites de envío de mensajes, pero la marca actual en vivo es Customers.ai, y su precio público ahora se centra en la resolución de identidad en lugar del clásico constructor de Messenger de bajo costo que la gente recuerda.

Hay una cosa más que la mayoría de los resúmenes omiten: ninguna de las opciones serias aquí es verdaderamente sin necesidad de registro. Esa frase funciona para aplicaciones de chat de IA para consumidores. No funciona para constructores de chatbots de Facebook porque la plataforma necesita permisos a nivel de cuenta, la conexión de tu Página, flujos guardados, almacenamiento de suscriptores y un lugar para gestionar las reglas de transferencia.

La conclusión práctica es simple. No preguntes solo, “¿Tiene un plan $0?” Pregunta, “¿Puedo conectar mi Página de Facebook, construir una conversación útil y mantenerla activa por más de un fin de semana sin actualizar?” Esa pregunta produce una lista mucho más corta.

Los 8 constructores de chatbots de Facebook gratuitos clasificados

Clasifiqué estas plataformas por valor combinado en $0: utilidad real de Messenger primero, presión de actualización segundo y cordura a largo plazo tercero. Si una herramienta es técnicamente gratuita pero te obliga a un plan de pago antes de que puedas hacer un trabajo significativo en Facebook, se descarta. Si una herramienta no es gratuita para siempre pero tiene un fuerte camino de prueba sin costo y una actualización de Messenger sensata, se mantiene en la conversación.

Nota importante: ManyChat es la lista más confusa para comparar porque sus páginas de precios públicos y documentos de ayuda no están perfectamente alineados en este momento. Los documentos de ayuda actualizados de marzo de 2026 describen un nuevo modelo de precios para cuentas creadas el 2 de marzo de 2026 o después, mientras que algunas páginas de precios públicos aún muestran mensajería gratuita para 1,000 contactos heredados. Si ManyChat es tu primera opción, verifica los precios reales mostrados dentro de tu cuenta y región antes de comprometerte.

ManyChat Is Still the Best Real Free Starting Point for Messenger

ManyChat takes the top spot because it remains the easiest serious answer to the exact question people are asking: “I want a Facebook Messenger bot builder I can actually start using for free.” The current March 2026 help docs for new-model accounts describe a $0 plan with up to 25 Active Contacts per month, 1 user, 1 inbox seat, up to 2 channels, and up to 4 live automations. That is a much smaller free tier than the older 1,000-contact language still floating around on some public pricing pages, but it is still a real forever-free entry point.

The important part is not the raw number. It is the fit. ManyChat still feels like a platform designed by people who understand what Messenger and social DMs are used for in the real world: comment triggers, simple lead magnets, welcome flows, FAQ replies, and lightweight sales qualification. If your business page gets modest traffic, 25 active contacts is enough to prove whether people will engage with your flow at all.

The catch is obvious. You will outgrow the free plan quickly if a post performs well, an ad starts converting, or you want more than a handful of automations live at once. Still, if you want the cleanest no-cost path into actual Messenger automation, ManyChat is where most people should start. And if the new caps feel too tight, this guide to ManyChat alternatives is the next smart comparison.

SendPulse Gives You the Most Real Room Before the Paywall

SendPulse is the best value pick if you care more about raw free capacity than the smoothest Messenger-first interface. Its current chatbot pricing shows a real free plan with up to 500 subscribers, 10,000 messages per month, and up to 3 chatbots. That is a lot more breathing room than ManyChat’s new 25 Active Contacts model for a small business that wants to test FAQs, lead capture, order updates, or simple promo flows without hitting a wall immediately.

The tradeoff is that SendPulse feels broader and slightly more utilitarian. It is trying to be an automation platform with email, CRM, and multichannel messaging layers, not just the slickest Facebook DM growth tool. That can be a strength if you want everything in one stack, but it also means the product feels less Messenger-native than ManyChat when you are building fast social automations.

If you want the most useful forever-free tier for a budget-conscious business page, SendPulse deserves a serious look. It is especially strong when your goal is “let me run a bot on Facebook without paying this month,” not “let me optimize every comment-to-DM funnel.” For pure no-cost runway, it is hard to beat in this list.

Chatfuel Is Good for Fast Facebook Tests, Not for Staying Free

Chatfuel still belongs in this roundup because its current Facebook automation page advertises that you can automate the first 50 conversations for free and then move into a free trial. Its public pricing also starts relatively clearly, with business plans from $23.99 per month and 1,000 conversations included before overage pricing. That makes Chatfuel more transparent than a lot of builders that bury usage math.

For a short proof-of-concept, Chatfuel is solid. You can set up a Facebook Page FAQ bot, test lead capture, connect an offer flow, and see whether your audience even wants to interact with the bot before you spend real money. That is useful. What it is not is a forever-free business setup you can just leave running indefinitely.

In other words, Chatfuel is free enough to validate. It is not free enough to ignore budgeting. If your main goal is to test one campaign or one support use case, it stays near the top. If your main goal is to avoid paying for months, it drops behind ManyChat and SendPulse.

Landbot Has the Best Sandbox, but Messenger Starts on Paid

Landbot is one of the easiest products to like when you are actually inside the builder. Its free forever Sandbox plan includes 100 chats per month, 1 seat, basic flow operations, limited integrations, and enough tooling to learn how your bot should behave. For prototyping, it is excellent.

The problem is simple and important: the real Facebook Messenger tier starts on paid Starter. Landbot’s USD pricing page shows Starter at $45 per month, or $36 per month billed annually, for web and Messenger chats. So while Landbot absolutely lets you build without paying, it does not really let you run a Messenger bot live on a forever-free plan the way a searcher probably expects.

That makes Landbot a smart choice for two types of readers. First, people who want to map and test a conversation flow before choosing a production platform. Second, teams that care a lot about builder experience and are open to paying once the structure feels right. For strict free-Messenger use, it sits below the top three.

MessengerBot Is a Better Upgrade Path Than a Better Free Plan

MessengerBot belongs in this ranking because it is directly relevant to Facebook Messenger automation, not because it offers the most generous forever-free tier. The public site currently shows a free-trial sign-up flow, while the pricing page itself starts on paid plans, with promotional pricing from $19.99 per 30 days for Premium. That Premium tier includes 1 Facebook account, 5 pages, unlimited subscribers, unlimited bulk messages, unlimited sequence messaging, and 1 chat widget and ecommerce store.

That combination tells you what MessengerBot is really optimized for. It is not trying to win the forever-free headline. It is trying to convert you from a test into an actual Messenger operating setup with broadcast tools, flow building, and Facebook-specific growth features that matter once the bot stops being a hobby.

If you only care about not paying for as long as possible, MessengerBot is not your first stop. If you care about what happens after the first successful campaign, it becomes more interesting. That is why I would not rank it above ManyChat or SendPulse for free use, but I would rank it above several “free” tools that stop making sense the moment you want Messenger to drive real business outcomes.

Tidio Works Better as a Support Stack Than a Free Facebook Builder

Tidio does have a real free forever baseline. Its help docs describe a free basic version, and its pricing page states that your first 50 Lyro AI Agent conversations are free for life and your first 100 visitors reached via Flows are free. That is useful if you are experimenting with support automation or AI-assisted responses.

Where people get confused is channel fit. Tidio is a strong support and live-chat platform. It is not the first product I would recommend to someone who specifically wants the best free Facebook Messenger bot builder for a business page. It makes more sense when your website inbox, help desk, and multichannel support view matter as much as Messenger itself.

So yes, Tidio deserves a place here because it can be part of a Messenger-adjacent setup and it does offer meaningful free access. But if Facebook is the main channel, its free plan is usually a detour rather than the cleanest route.

Botsify Gives You a Trial and a Broad Channel List, Not a Cheap Forever Plan

Botsify’s current pricing positions it more as an AI-agent builder than a classic Messenger-first no-code bot tool. The self-serve builder plan starts at $49 per month and includes 2 AI agents, 6,000 credits, documents and web-search integrations, scheduling, and deployment to channels such as Messenger, SMS, website, WhatsApp, Instagram, Telegram, and Slack. The free piece is the trial, not an ongoing forever-free usage tier.

That makes Botsify easy to categorize. It is useful if you are agency-minded, want omnichannel experimentation, or like the newer “agent” framing more than traditional flow builders. It is not the strongest answer for a small business owner who typed “facebook chatbot builder free” because they want to run a practical page bot without a monthly bill.

In other words, Botsify is not bad software. It is just a mismatch for the strictest version of this keyword. There is a difference between “lets me try it without paying” and “lets me operate it without paying,” and Botsify sits in the first bucket.

MobileMonkey Is a Legacy Search Term More Than a Fresh Recommendation

MobileMonkey is still searched heavily enough that ignoring it would make this roundup less useful. But readers deserve the blunt version: if you are expecting the old MobileMonkey free Messenger builder from years ago, that is not really the current story anymore.

Legacy help docs under the old MobileMonkey setup still mention a free plan with a 1,000-message send limit. But the current public Customers.ai pricing is centered on identity resolution, with a 7-day free trial and paid plans starting around $600 per month. That is a radically different buying decision from “free Facebook chatbot builder.”

If you already run an old MobileMonkey setup, those legacy docs may still matter. If you are starting fresh in 2026, I would not treat MobileMonkey as a serious free-plan recommendation. It belongs in the list because people still compare it. It ranks last because the current product-market reality no longer matches the old free-plan expectation.

Feature Comparison: What Each Free Tier Gives You

This is the table I wish more free-plan roundups would publish. It answers the three questions that usually matter first: do you get real Messenger access, how much can you do before paying, and what wall you hit first.

The biggest pattern in that table is not pricing. It is fit. Only a few platforms are truly trying to serve the “free Facebook Page bot” use case directly. Many others either let you test the builder without paying or give you a website-first free plan that becomes Messenger-capable only after you upgrade.

How to Build Your First Free Facebook Chatbot in 15 Minutes

If you want the fastest real-world path, use ManyChat or SendPulse for the first build. They give you actual no-pay Messenger runway instead of a pure sandbox. Keep the first version boring on purpose. Boring bots usually outperform clever ones because they get to the answer faster.

1. Choose one job for the bot. Pick FAQs, lead capture, booking requests, or after-hours replies. If you try to make the bot do support, sales, qualification, and promotions on day one, you will waste your free limit on a messy draft.
2. Connect your Facebook Page and grant full permissions. Most setup failures come from incomplete permissions, not bad copy. If the platform cannot see the page properly, nothing downstream will behave consistently.
3. Start from a template, not a blank canvas. Templates are not just for beginners. They prevent you from forgetting basics like fallback responses, welcome flows, or reply buttons.
4. Build one menu with three choices. A strong free-plan starter menu is usually “Get a quote,” “Ask a question,” and “Business hours.” That covers most business-page traffic without building ten branches you do not need yet.
5. Write a fallback that sounds human. Something like, “I can help with pricing, opening hours, and booking. If you need a person, leave your question and we will reply shortly.” That one message saves a lot of bad bot experiences.
6. Add one conversion step. Ask for an email, phone number, booking preference, or product interest. If the bot never captures intent, it is just decorative automation.
7. Test on mobile from a real Facebook user account. Messenger flows often look fine in a builder preview and awkward on an actual phone. Tap everything yourself.
8. Watch your limits for a week before rebuilding anything. The first version should teach you where users click and where the free tier pinches. That data matters more than adding extra branches immediately.

If you want the wider walkthrough on construir un chatbot sin codificación, read that next. It is the better companion piece once you have chosen a platform and need the practical setup flow, not just the pricing comparison.

Free Tier Limits You’ll Hit First

Most people assume message volume is the first thing that breaks a free chatbot plan. Sometimes it is, but more often the first limit is something less obvious.

Contact caps usually hurt before message caps. ManyChat’s newer free-plan model is the clearest example. You might not send many messages, but if a small burst of people interact with the bot during the billing cycle, the active-contact ceiling can show up fast.

Automation count is the next invisible wall. A free plan that allows only a few live automations can feel fine while you are building, then suddenly cramped once you add welcome flows, FAQ replies, comment triggers, and a lead magnet.

AI allowances are usually tiny. Tidio’s first 50 AI conversations free for life sounds nice until you realize a few real customer sessions can burn through that quickly. Trial-driven AI builders have the same problem. They are generous enough to impress you, not generous enough to replace budgeting.

Team access becomes a problem sooner than most businesses expect. One user and one inbox seat sounds fine when you are setting up alone. It becomes annoying the moment a colleague wants to monitor or jump into live conversations.

Branding and channel restrictions matter more than they look on the pricing page. A “Powered by” label or missing SMS, WhatsApp, or email support might not matter for testing. It matters once the bot becomes customer-facing and part of a real campaign.

Legacy pricing pages can waste your time. ManyChat and MobileMonkey both show why. If you read an old comparison or a cached pricing page without checking the newest help docs, you can design your whole build around a limit that no longer exists.

When to Upgrade From Free to Paid

The right time to upgrade is not “when the vendor annoys you.” It is when the free plan starts changing how you run the business.

Upgrade when your bot starts generating leads every week and you are actively avoiding extra contacts because you do not want to trip the cap. Upgrade when more than one person needs inbox access. Upgrade when you want sequences, better analytics, AI replies at meaningful volume, or cleaner integrations into your CRM or sheets.

For most small businesses, the free plan is best used as a validation layer. Prove that customers will message you. Prove that your FAQ flow reduces repetitive replies. Prove that at least one conversion path works. Once that happens, the smartest move is often to stop optimizing around a $0 constraint and choose the platform you can live with for the next year.

Completely Free Forever vs Free Trial Only

This is the cleanest way to think about the eight platforms after all the pricing-page noise.

If your non-negotiable requirement is free forever on actual Facebook Messenger, the list gets much shorter very quickly. ManyChat and SendPulse are the two strongest answers. Everything else requires more compromise, more nuance, or a faster jump to paid.

Common Free Chatbot Builder Mistakes

The easiest way to waste a free plan is to build like you already have a paid one. These are the mistakes I see most often.

• Choosing by headline instead of channel access: “Free forever” sounds great until you notice the free tier is website-only and Messenger starts on paid.
• Building too many branches in week one: On a capped plan, every extra automation should earn its place. Start with one menu, one fallback, and one conversion path.
• Ignoring how contacts are counted: Contact-based billing and contact-based limits are not the same as follower counts, and that mistake creates surprise paywalls.
• Skipping human handoff: A free bot that cannot gracefully hand off or collect a follow-up question creates a worse customer experience than no bot at all.
• Trusting old tutorials without checking current pricing: MobileMonkey is the classic trap here, and ManyChat’s 2026 pricing shift makes this even more important.
• Using the wrong tool for the real job: Tidio is great when the job is support inbox management. ManyChat is better when the job is Messenger growth automation. Free comparisons fail when those jobs get mixed together.

If you are still deciding between a Messenger-first builder and a broader support or website chatbot tool, go back to the use case, not the feature count. That sounds obvious, but it is the one habit that keeps free plans useful instead of frustrating.

If your main problem is setup rather than pricing, go back to construir un chatbot sin codificación before you switch platforms. A surprising number of “free plan” complaints are really first-build mistakes.
