Quick answer
Pick Respond.io if a support team needs one multichannel inbox with routing and reporting: it starts at $79 a month for five users on the official API, plus Meta's per-message fees and AI credits. Pick Replai if you run one to five WhatsApp numbers with no agent team: it pairs by QR in 30 seconds, from $19 a month with AI included and no message fees, on an unofficial connection.
- Respond.io Starter is $79 a month billed annually for five users, with 5,000 AI credits included.
- Respond.io is an official Meta BSP: Meta's per-message fees apply and AI overage is $15 per 1,000 credits.
- Replai pairs by QR in 30 seconds and costs $19, $49 or $99 a month with AI included.
- Respond.io's official API carries very low restriction risk; Replai's linked-device connection is unofficial.
If you're researching customer-service tools for WhatsApp, two names come up fast: Respond.io (born in Malaysia, now globally used) and Replai (built in Malaysia for small businesses). Both promise WhatsApp at scale. Both have AI. They're built for very different shapes of business — and that's the comparison that actually matters.
This is a comparison from the Replai team. Respond.io is a strong, mature product; we're being fair to it. We have a perspective, so read with that in mind.
At a glance
The per-message row below is Meta's billing, not Respond.io's. Since 1 July 2025 the WhatsApp Business Platform charges per delivered template message (marketing, utility or authentication), while non-template replies inside the 24-hour customer service window are free (Meta for Developers, 2025). Respond.io passes those fees through as a Business Solution Provider; Replai pairs to your number as a linked device and never touches that billing.

What does Respond.io do better than Replai?
Multichannel is real. WhatsApp + Instagram + Messenger + WeChat + LINE + SMS + web chat in one inbox. If your customers actually reach you across all those channels and you need a single agent-routing pane, Respond.io is genuinely strong.
Official WhatsApp Business API. Respond.io is a Meta-approved BSP. Template-message broadcasts, opt-in subscriber lists, the green-tick verification, full WABA compliance.
Multi-agent CRM workflows. Routing rules, agent assignment, SLA tracking, ticket-shaped conversation handling. Built for a real support team, not a solo founder.
Customer Conversation Management as a category. Respond.io has built out CRM-shaped opportunity tracking, lifecycle stages, broadcast campaigns. It's a real platform play.
What does Replai do better than Respond.io?
No Meta application, no waiting. Replai pairs to your WhatsApp Business number as a linked device — same way WhatsApp Web works. 30 seconds via QR. No Meta business verification, no BSP onboarding, no waiting weeks.
No per-conversation fees. Meta's WABA charges per conversation window. Those fees pass through whatever BSP you sign with — including Respond.io. Replai's flat monthly avoids that whole cost surface.
Knowledge-grounded AI by default. Drop a Google Doc with your menu / fee list / catalog and Replai answers from it. Respond AI is positioned as agent-assist plus generative reply credits — it works, but it's billed separately and assumes you've designed the conversation flows first.
Voice notes + product photos natively. Customer sends a voice note in Bahasa, or a product photo asking "in size 8?" — Replai handles it in context. On Respond.io that's a higher AI tier or doesn't work at all.
One flat price. No per-contact tier, no AI credits running out mid-month, no separate broadcast fees. The economics work for a salon owner with 2,000 customers, not a 50-agent BPO.
When to pick Respond.io
- You're a mid-market business and customers contact you across 4+ channels
- You have a multi-agent support team that needs routing, SLAs, ticketing
- You run outbound broadcast campaigns to opted-in lists at scale
- You're at enterprise volume and need the full WABA + BSP relationship
- Per-channel agent inboxes are a deal-breaker
When to pick Replai
- You're a small business and 80%+ of your customer messages come via WhatsApp
- You don't want to deal with Meta business verification or BSP onboarding
- Most of your messages are repetitive questions — pricing, hours, availability, stock
- Your customers write in mixed languages and send voice notes
- You'd rather pay one flat monthly fee than per-conversation + per-contact + per-AI-credit
- You'd rather drop a Google Doc in than build a flow tree
The honest summary
Respond.io is the customer-conversation platform for serious multichannel teams in SEA and beyond. Replai is built for the simpler shape: a small business that lives on WhatsApp and just wants the repetitive 70% answered automatically, without the Meta application process and without per-conversation fees.
If you're a 30-person BPO running campaigns, pick Respond.io. If you're a salon owner answering the same five questions at 11pm, pick Replai.

Frequently asked questions
How much does Respond.io cost in 2026?
- Starter is $79 a month billed annually or $99 monthly for five users with unlimited contacts and 5,000 AI credits. Growth is $159 or $199 for ten users, starting at 1,000 monthly active contacts with $12 per extra 100. Advanced is $279 or $349. Meta's per-message fees apply on WhatsApp.
Is Replai a good Respond.io alternative?
- For a small business on one to five WhatsApp numbers with no agent team, yes: Replai pairs to the WhatsApp number you already have as a linked device, so there is no Meta application and no per-message fee. Plans are $19, $49 or $99 a month with the AI included, and a 7-day trial needs no card. For a multichannel support team that needs assignment and reporting, Respond.io is the stronger product.
Does Respond.io include AI replies?
- Partly. Each plan includes a monthly allowance of AI credits that features like AI Agent and AI Assist consume, with overage at $15 per 1,000 credits. Replai includes the AI on every plan with no credit system; a conversation is one thread of up to five replies.
Which is safer, Respond.io or Replai?
- Respond.io uses the official WhatsApp Business API, which is sanctioned by Meta and carries very low restriction risk. Replai's linked-device connection is unofficial and can be restricted if a number behaves like spam; it mitigates that with rate limits and warm-up but cannot guarantee it.
