Handed to a human teammate
They pick up with the full conversation and context carried over. No dead ends, no repeating.
If you are searching respond.io vs Wati, or respond.io vs ManyChat, or one of the narrower matchups like respond.io vs SleekFlow and respond.io vs Kommo, you are comparing a specific slice of the market: WhatsApp-first platforms that grew into multi-channel inboxes. They look almost identical on a feature grid. They bill in completely different ways, and that is where the real decision sits.
Three different meters run in this category. Respond.io and SleekFlow charge by monthly active contact, so your bill tracks how many different people message you. ManyChat charges by total contact stored, which means the bill grows even when those contacts go quiet. Kommo and Wati charge per user seat. Pick the wrong meter for your traffic shape and you overpay by a multiple, not by a margin.
Every price below came off the vendor's own pricing page on July 26, 2026. Two things worth knowing before you read it: SleekFlow now serves US dollars to a US visitor, rechecked 22 September 2026, and older write-ups quoting it in Hong Kong dollars are out of date. Wati no longer shows its plan prices publicly at all. MessageAgent is in the table too, and we are honest about the fit. We are the wrong choice if you need WhatsApp broadcast marketing campaigns, which Wati and ManyChat do well. We are the right choice if you want one AI that answers, qualifies, and books across six channels on a flat $79, $199, or $499 a month, with no contact meter and no per-resolution fee.

What you get
Everything one AI agent handles
No contact meter at all
Respond.io, SleekFlow and ManyChat all bill against contacts in one form or another, so a good month costs you more. Our tiers are flat, which means a spike in inbound messages changes your workload and not your invoice.
One AI brain, six channels
Most of this field is WhatsApp with other channels bolted alongside. One persona with shared memory works across SMS, WhatsApp, Instagram DM, Facebook Messenger, web chat and email, so a buyer who DMs then texts is one conversation.
Billed in dollars, published openly
Wati geo-prices by region, serving euros to a European connection and dollars to a US one, and SleekFlow keeps its upper tier behind a Book a Demo button. Our three tiers are on the pricing page in USD, and you can read them without booking a call.
It closes, not just replies
Beyond answering, the AI qualifies inbound leads against your rules, books appointments against real availability, writes the contact to the CRM, and escalates with the full thread attached when a human is genuinely needed.
Message fees at cost
Carrier and Meta fees pass through with no markup. Several platforms in this table resell WhatsApp traffic at a margin on top of what Meta already bills you for the same conversation.
Built for US compliance
AI is disclosed on every conversation, SMS honors STOP and prior express consent under TCPA with 10DLC registration managed for you, and WhatsApp opt-in plus approved templates are handled by default.
Conversation Console
Try it on every channel
Pick a channel and a sample customer message, and watch the same AI agent reply on brand, take the action, log it to the CRM, and hand off to a human in one tap.

Common questions
Respond.io comparison questions
Respond.io vs Wati: which is better?
Respond.io is the broader platform, Wati the narrower WhatsApp specialist. Respond.io covers WhatsApp, Instagram, Messenger, SMS, email and web chat, publishes its prices at $79 to $279 a month, and includes AI on Growth and above. Wati is WhatsApp-first with strong broadcast and template tooling. Read from a US connection on 25 September 2026, Wati Growth is $59 a month billed yearly ($69 monthly), Pro $119 ($149) and Business $279 ($349), with extra users at $39 on Pro and $89 on Business, plus per-message charges on its rate card.
Respond.io vs ManyChat: what is the real difference?
They serve different jobs. ManyChat is a creator growth tool built around Instagram and Messenger funnels, comment-to-DM triggers and list building. Respond.io is a sales and support inbox for teams handling real conversations across channels. Both now bill by monthly active contact. ManyChat Pro is $29 a month billed yearly for 2,500 active contacts, with overage at $0.038 each, while respond.io starts at $79 for its Starter plan.
Respond.io vs SleekFlow: how do they compare?
At 1,000 contacts the top tiers are priced identically: respond.io Advanced and SleekFlow Premium both cost $279 a month billed yearly and $349 month to month. At entry SleekFlow Essential is US$49 against respond.io Starter at $79, and neither includes AI agents. SleekFlow's US pricing page, read on 7 October 2026, now hosts US SMS and VoIP numbers at US$1 a month and WhatsApp numbers at US$15, so the contact tiers decide more of the bill than channels do.
Respond.io vs Kommo: which should a sales team pick?
Kommo if you want a CRM pipeline first, respond.io if you want a conversation platform first. Kommo is a messenger-based CRM at $15 to $45 per user monthly with a six-month minimum term, and it is genuinely cheap for a small team. Respond.io is stronger at high-volume routing, automation and AI across channels, but it costs more once you add users.
How much does respond.io cost?
Respond.io publishes three self-service tiers: Starter at $79, Growth at $159 and Advanced at $279 per month, with roughly 20 percent off on annual billing. Growth and Advanced include 1,000 monthly active contacts and then charge $12 and $15 per additional 100 contacts. Extra users cost $12 to $24 each. AI usage is included on Growth and above.
What is the cheapest respond.io alternative?
On headline seat price, Kommo at $15 per user monthly, though the six-month minimum term means you commit to $90 per seat up front. On total predictability, a flat plan like MessageAgent at $79 a month, because no contact meter or per-resolution fee moves the number. The cheapest option depends entirely on whether your cost is driven by seats or by conversation volume.
Is respond.io worth it in 2026?
For a team running genuine WhatsApp sales volume, usually yes. Including AI at no extra cost on Growth and above is unusual in a category that mostly meters AI separately, and the routing and automation are mature. It gets expensive when many different people message you in a month, since every extra 100 monthly active contacts adds $12 to $15 on top of the platform fee.
What does monthly active contact billing actually mean?
You pay for each unique person who exchanges a message with you inside a billing month, not for the size of your database. Someone who messages you twenty times counts once, and a contact who stays quiet costs nothing. It suits support inboxes with a stable customer base and punishes businesses whose traffic arrives as a lot of one-time conversations.
Which of these platforms is best for WhatsApp marketing campaigns?
Wati or ManyChat. Both are built around broadcasts, template campaigns and list growth, and Wati in particular is designed for sending approved WhatsApp templates at volume. MessageAgent deliberately does not do broadcast marketing. We handle inbound conversations and the follow-up around them, so if campaign sending is your main job, pick one of those two instead.
Which tool should I pick if my customers message on SMS and Instagram, not just WhatsApp?
Check how each platform treats the non-WhatsApp channels, because most of this field treats them as secondary. Wati is WhatsApp-led and lists SMS fallback only as a beta on its Business plan, ManyChat is strongest on Instagram and Messenger, and SleekFlow charges separately per hosted number. MessageAgent runs one AI with shared memory across SMS, WhatsApp, Instagram DM, Messenger, web chat and email, priced the same whichever channel the buyer chooses.
