Best Free Chatbot Platforms 2026 — Ranked for Budget-Constrained SMBs

The 2026 ranking — 6 free-tier paths

1. Best Free Chatbot 2026·#1
   

   SendPulse

   Best for multi-channel SMB free entry

   From:

   $12/month Pro

   Editorial score: 86 (paid tier reference — our highest across 15 Tier 1 platforms) • Free tier: 3 bots / 500 subscribers / 10,000 messages per month aggregated across all bots / 4 channels (Telegram, Facebook Messenger, WhatsApp, Live Chat) • Upgrade trigger: 500 subscribers cap or need for AI

   SendPulse Free is the most generous perpetual free tier in the chatbot-builder category — 3 bots, 500 subscribers, and 10,000 messages per month aggregated across all bots, across Telegram, Facebook Messenger, WhatsApp, and Live Chat (no credit card, no expiry). A global platform (3M+ users worldwide, broadest multi-language coverage in our review set) that scales SMB through enterprise. The honest catch: AI integrations (ChatGPT, Claude, Gemini, DeepSeek) require a paid plan; on Pro ($12/month) they run on your own provider keys. See the side-by-side breakdown in our free-plan spec-sheet comparison.

   Best fit: Early-stage business in any region testing a combined channel stack on a global platform.

   Strong fit if

   Early-stage SMB testing a real multi-channel deployment (WhatsApp + Telegram + Messenger) on the most generous perpetual free plan in the category. Headroom to grow on the same platform — Pro at $12/month is the cheapest functional paid tier in our Tier 1 catalog.

   Weak fit if

   You need AI on the free tier (AI integrations require a paid plan, Pro from $12/month) or your strategy requires more than 500 subscribers or 10,000 messages/month before paid upgrade.

   Tidio

   Best for website widget free entry

   From:

   $29/month Starter

   Editorial score: 75 (paid tier reference) • Free tier: 50 conversations/month + basic AI + live-chat • Upgrade trigger: 50 convo cap

   Tidio Free tier covers website widget + basic live-chat + limited Lyro AI. Best for very small SMB websites testing chatbot deployment. Native Shopify App Store presence even on Free tier.

   Best fit: Solo-operator website or early-stage Shopify store. Upgrade to Starter ($29/month) once volume crosses 50 convos/month.

   Strong fit if

   Solo-operator website or early-stage Shopify store. Upgrade to Starter ($29/month) once volume crosses 50 convos/month.

   Weak fit if

   Your conversation volume exceeds 50/month or you need full Lyro AI capabilities beyond the limited free allocation.

   Botpress

   Best for cloud free tier with AI included

   From:

   $189/month Plus (monthly-billed)

   Editorial score: 81 (paid tier reference) • Free tier: 100 conversations/month, 1 seat, 3 AI agents, AI usage included, Botpress-branded web chat only • Upgrade trigger: 100-conversation cap (no top-ups on Free) or needing WhatsApp

   Botpress is a commercial cloud platform with open-source roots: it launched in 2016 as open source and has since been rearchitected into the current cloud product. Free gives you 100 conversations a month with LLM usage bundled into the plan (no separate token bill), 3 AI agents, Studio + Desk + ADK access, and a Botpress-branded web chat widget; at 100 conversations the agent stops handling new ones until the next month. BYOLLM is partial: OpenAI, Anthropic and other providers are first-class integrations, but inference billing flows through Botpress's AI Spend model by default. WhatsApp and white-label web chat start at Plus ($189/month monthly-billed, $150/month annual).

   Best fit: Developer-led SMB or technical operator evaluating an AI agent before committing to Plus.

   Strong fit if

   Technical or developer-led SMB evaluating an AI agent on website chat. 100 conversations a month with AI usage included is the most AI headroom of any free tier in this list.

   Weak fit if

   You need WhatsApp or other messaging channels on free (Free is web chat only; WhatsApp starts at Plus), you are non-technical, or the step up to Plus at $189/month monthly-billed is outside your budget.

   81/100

   Chatbase

   Best for AI knowledge base testing

   From:

   $40/month Hobby

   Editorial score: 73 (paid tier reference) • Free tier: AI knowledge base testing, limited messages • Upgrade trigger: Message volume cap

   Chatbase Free tier allows AI knowledge base upload and testing without credit card. Best for evaluating RAG deployment quality before committing to Hobby ($40/month) for production.

   Best fit: Operator evaluating AI support deflection feasibility. 8-minute time-to-first-bot makes testing cheap.

   Strong fit if

   Operator evaluating AI support deflection feasibility. 8-minute time-to-first-bot makes testing cheap.

   Weak fit if

   You need multi-channel coverage beyond website widget or production message volume beyond the free cap.

   Typebot

   Best for open-source visual builder

   From:

   $0 software + ~$10/month VPS

   Editorial score: 70 (paid tier reference) • Free option: Open-source self-hosted • Cost: $0 software + ~$10/month VPS

   Typebot is the open-source visual flow builder. Brazil-strong community. Self-hosted deployment is permanent-free. Cloud tier exists ($39/month) for operators not wanting self-hosting overhead.

   Best fit: Brazil-based SMBs (strongest community); technical operators who want visual builder without code requirement.

   Strong fit if

   Brazil-based SMBs (strongest community); technical operators who want visual builder without code requirement.

   Weak fit if

   You want full feature parity with cloud tier without self-hosting overhead, or you operate outside the Brazilian community ecosystem.

   Manychat

   Best for Meta-channel free entry

   From:

   $17/month Essential (WhatsApp and AI from $39/month Pro)

   Editorial score: 84 (paid tier reference) • Free tier: 25 contacts, 2 channels chosen from Instagram / TikTok / Messenger / Telegram, 1 user, no WhatsApp / SMS / Email • Upgrade trigger: 25 contacts cap

   Manychat Free tier tightened sharply in March 2026 — down from 1,000 contacts to 25, with no WhatsApp/SMS/Email and AI Pro-only. The free tier is now a sampler, not a production path; usable to test Instagram + Messenger comment-to-DM workflows before committing to Pro ($39/month). Strong overall editorial score (Manychat ranks #2 of 15 platforms) but the constrained free plan lands it last in this specific list.

   Best fit: Solo creator evaluating Manychat's Meta-channel builder UX before paid upgrade.

   Strong fit if

   Solo creator or early SMB testing Instagram + Messenger comment-to-DM workflows before committing to Pro. Manychat ranks #2 overall by editorial score (84) — placed last in this free-tier ranking only because the 25-contact cap is the tightest in our review set.

   Weak fit if

   You need AI features on free tier (AI bundles into Pro only), production volume beyond the 25-contact cap, or any WhatsApp / SMS / Email channel coverage on free.

Editorial scoring breakdown — free tier coverage

What "free" actually means — three kinds of free

The word "free" hides three structurally different deals, and confusing them is the most common buyer mistake in this category. Before comparing limits, classify what kind of free each platform is actually offering.

1. The perpetual free tier (freemium with no clock). A genuine no-expiry plan you can run indefinitely, capped on volume rather than time. SendPulse (3 bots / 500 subscribers / 10,000 messages a month, no credit card) and BotPenguin's Baby plan (1,000 messages a month, all five channels, unlimited subscribers) are the clearest examples. Both are explicitly "free forever," not 14-day trials wearing a free-tier costume. Tidio's plan also sits here, but with a catch noted below. Botpress's cloud Free plan (100 conversations a month, AI usage included) belongs here too, sized for evaluation more than production.

2. Open-source self-hosted (the only truly unlimited-volume free). Typebot publishes its source. Self-host it and the software licence cost is genuinely $0 at any volume, but you pay in infrastructure (~$10/month for a VPS) and operator time. Typebot is released under the Functional Source License (open-source with a non-compete clause), with a solo maintainer (Baptiste Arnaud) and a 10,000-star GitHub repo. This is the only path to zero-marginal-cost scaling, and the only one that requires you to own uptime, security patching, and backups yourself. Botpress started as open source in 2016 but is now a commercial cloud product; its free route is the cloud Free plan above, not self-hosting.

3. The freemium gate (free as a sampler, not a home). A free plan that exists mainly to demonstrate the product before forcing an upgrade. Manychat's post-March-2026 Free tier (25 contacts, no WhatsApp) is the textbook case: usable to see the builder, not to run a business. Chatbase's 50-credit Free plan is the same shape for AI support bots. These are real, but treat them as evaluation sandboxes with a short fuse.

A fourth cost cuts across all three: AI is almost always gated. SendPulse, Manychat, and BotPenguin all exclude their AI layer from the free plan (SendPulse's AI integrations start on Pro and run on your own provider keys). Where AI is included free (Botpress's 100 conversations a month, Chatbase's 50 credits, Tidio's 50 one-off Lyro conversations), it is metered tightly enough that any real deployment exhausts it fast. Budget separately for AI, typically $20-100/month for managed AI, or token costs (often $10-50/month at SMB scale) if you bring your own model on an open-source stack.

Per-platform free-tier reality

The headline number rarely tells you what is actually gated. Here is what each free option gives you, what it withholds, and the trigger that ends the free ride.

SendPulse Free (Basic). The most generous perpetual free tier we evaluated in the chatbot-builder category: 3 chatbots, 500 subscribers, and 10,000 messages per month aggregated across all bots, plus 10 variables and 10 triggers, the full visual flow builder, premade templates, and limited API access, with no credit card and no expiry. The honest catch: AI integrations are excluded from Free. The AI Agent block is visible in the builder, but connecting ChatGPT, Claude, Gemini or DeepSeek requires Pro, where they run on your own provider keys. Upgrade trigger: you cross 500 subscribers, or you need AI. The upgrade is cheap, as Pro starts at $12/month monthly-billed, the category's lowest functional paid tier.

Tidio Free. Genuinely usable for a very small website: 50 conversations, 100 Flows visitors (trial allowance), 10 seats, and 50 Lyro AI conversations. The honest catch buyers miss repeatedly: the 50 Lyro conversations are a one-off allowance, not a monthly refresh. Once spent, AI handling stops until you move to Growth ($59/month). Lyro itself is strong (it runs on Claude with MCP support), but the free taste is small. Upgrade trigger: 50 monthly conversations, or exhausting the one-off Lyro pool. Cheapest paid tier is Starter at $29/month.

Botpress Free (cloud). A commercial cloud product with open-source roots, not a self-hosted download. Free covers 100 conversations a month, 1 seat, 3 AI agents, Studio + Desk + ADK access, and a Botpress-branded web chat widget, with LLM usage bundled into the plan rather than billed per token. The honest catch: web chat is the only channel on Free (WhatsApp and white-label web chat start at Plus), there are no top-ups, so the agent stops taking new conversations at 100 until the next month, and BYOLLM is partial, since inference billing flows through Botpress's AI Spend model by default. This is a developer's free more than an operator's. Upgrade trigger: the 100-conversation cap, or needing WhatsApp. Plus is $189/month monthly-billed ($150/month annual).

Chatbase Free. Built for evaluating AI support deflection, not running it: 1 agent, 0 AI Actions, and 50 message credits per month, restricted to basic model access, since the advanced OpenAI and Anthropic models start at Hobby. The honest catch: 50 credits is a demo budget; a single curious afternoon can drain it, and there is no path to free production. Strong point is speed: we measured 8 minutes from signup to a working FAQ bot. Upgrade trigger: message-credit cap or needing advanced models / Actions. Hobby is $40/month (500 credits, 5 agents).

Typebot. Two free routes. The cloud Personal Free plan ($0, 200 chats/month, unlimited typebots) is genuinely usable for a small lead-capture or quiz bot, while the self-hosted route is unlimited-volume free under the FSL. Genuine BYOLLM ("AI provider agnostic") means AI cost is your own LLM key, not a platform markup. The honest catch: cloud paid tiers are monthly-only (no annual discount), and self-hosting means you own uptime, patching, and backups. Cloud Starter is $39/month (2,000 chats).

Manychat Free. Tightened sharply in March 2026: 25 active contacts (down from 1,000), two channels chosen from Instagram / TikTok / Messenger / Telegram, one user, one inbox seat, and no WhatsApp, SMS, or Email. AI is Pro-only. In our hands-on session the gating ran deeper than the pricing page implies. Every CRM-style trigger (tag applied, field changed, contact created) is Pro-locked, leaving the free trigger surface channel-event-only. The honest catch: for the LATAM/Brazil WhatsApp-commerce buyer Manychat is most famous for, the free tier is a non-starter, since WhatsApp begins at Pro ($39/month monthly-billed), not the $17 Essential. Upgrade trigger: 25 contacts, or needing WhatsApp/AI.

BotPenguin Baby Free. The most underrated free plan in the list: $0 forever, 1,000 messages per month, 1 chatbot, all five channels (WhatsApp, Instagram, Messenger, Telegram, Website), and unlimited subscribers, no credit card. That WhatsApp-on-free combination is rare, since Manychat gates WhatsApp behind Pro. The honest catch: multi-LLM model selection is King-tier only ($99/month), and the third-party review sample is thin, so do extra diligence. Upgrade trigger: 1,000 monthly messages or needing more than one bot. Little is $29/month (3,000 messages, 5 bots, 5 seats).

Free-tier limits at a glance

When the free tier stops being enough

Free plans fail in predictable ways. Knowing the threshold lets you plan the upgrade instead of being surprised by it.

The contact/subscriber wall. The hardest, earliest wall for marketing-led bots. Manychat's 25-contact cap is reached in days by any live campaign; SendPulse's 500 subscribers and BotPenguin's unlimited subscribers buy far more runway. If you are capturing leads, model your 30-day capture rate against the cap before committing.

The message/conversation ceiling. Support and conversational bots hit this next. Tidio's 50 conversations, Chatbase's 50 credits, Botpress's 100 conversations, BotPenguin's 1,000 messages, and SendPulse's 10,000 messages span two orders of magnitude, so match the cap to your real inbound volume, not your optimistic one. A site doing even 5-10 support chats a day exhausts a 50-conversation plan in under a week.

The AI exhaustion trigger. The quietest wall. Tidio's one-off Lyro pool and Chatbase's monthly credits are the clearest cases: AI simply stops, mid-month, and the bot silently degrades to scripted fallbacks. If AI handling is core to your use case, assume you will pay for it from month one.

The channel gate. A capability wall, not a volume one. The moment a WhatsApp-led strategy meets Manychat's free tier, the answer is "upgrade to Pro" — no amount of staying small avoids it. BotPenguin (WhatsApp on free) and SendPulse (WhatsApp on $12 Pro) sidestep this.

The self-host maintenance tax. Open-source has no volume wall, but it has a time wall. The honest threshold for Typebot self-hosting is whether you can absorb ~10-30 hours of initial setup plus ongoing patching, monitoring, and backups. Below roughly one technical person-day per month of spare capacity, the "free" software is more expensive than a $12-29 SaaS tier once you price your own time.

As a rule of thumb: a real SMB deployment with genuine traffic crosses a perpetual free cap within 30-90 days, and a freemium-gate plan (Manychat Free, Chatbase Free) within days to a few weeks. Plan the paid step deliberately rather than discovering it when the bot stops responding.

How to choose

Use case: Multi-channel messaging on a real free plan (WhatsApp, Telegram, Messenger, live chat) → SendPulse Free. Website widget → Tidio Free. AI agent evaluation with model usage included → Botpress Free. AI deflection testing on your own content → Chatbase Free. Long-term cost minimization → Typebot self-hosted. Instagram/Messenger marketing → Manychat Free.

Technical capability: Non-technical → SendPulse, Tidio, Chatbase, Manychat Free tiers. Technical → Botpress Free, Typebot OSS.

Growth trajectory: Plan upgrade to paid tier within 30-90 days if real-volume traffic.
