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.

2. Open-source self-hosted (the only truly unlimited-volume free). Typebot and Botpress publish their source. Self-host either one 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.

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. Where AI is included free (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: ChatGPT integration is excluded from Free, so AI-powered conversational nodes require Pro. 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.

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.

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.

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).

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).

Botpress (open-source self-hosted). No volume cap on the software itself; you control cost via your VPS and BYOLLM token spend. The honest catch: this is a developer's free, not an operator's. Budget JavaScript familiarity, DevOps capacity, and the maintenance tail. SOC 2 + GDPR are available on self-hosted deployments. Long-term cheapest at high volume; highest setup tax.

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 carries the same operator-time tax as Botpress. Cloud Starter is $39/month (2,000 chats).

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, 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 Botpress and 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: Instagram/Messenger marketing → Manychat Free. Website widget → Tidio Free. AI deflection testing → Chatbase Free. Long-term cost minimization → Botpress or Typebot self-hosted.

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

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