What SleekFlow is

SleekFlow is an omnichannel conversation platform with strong roots in Southeast Asia. You get a shared inbox across WhatsApp, Instagram, Messenger and more, a visual Flow Builder for automation, broadcast campaigns, and AI agents on its AI tiers. It is an official WhatsApp Business API provider, which brings the green tick and Meta-sanctioned messaging, and also brings Meta's per-message fees and API hosting charges on top of the subscription.

What ReplyKit is

ReplyKit is an AI employee for your WhatsApp number. It answers customers within seconds using your website, PDFs and Q&A, asks qualifying questions, books a real slot in your calendar, and escalates to you when a human is needed. It keeps a simple CRM current on its own. You connect by scanning a QR code, so there is nothing to apply for and nothing to pay Meta.

Pricing in USD and RM

SleekFlow

ReplyKit

Every plan is listed on the ReplyKit pricing page, and every plan starts with a 7-day free trial.

Worked example. A physio clinic in Petaling Jaya with two staff answering WhatsApp. SleekFlow Pro AI: RM 449 a month plus WhatsApp API fees, and someone builds the flows. ReplyKit Starter: $29 a month, agent answers and books, nothing to build beyond pasting the website and setting opening hours.

AI agents: flow-driven vs content-driven

SleekFlow's AI agents live inside its Flow Builder, which is a real strength if you want AI as one step in a bigger journey, with hand-offs to campaigns, tags and integrations. It rewards a team member who likes building automations.

ReplyKit's agent is content-driven. Give it your website URL, PDFs and a few Q&A pairs and it answers only from those, in over 30 languages, saying so when it does not know. It transcribes voice notes, understands photos, offers real appointment slots, updates the CRM and logs the questions it could not answer so you can teach it with one click. There is no flow to design, and nothing to maintain when your prices change beyond updating the source.

Setup and risk

SleekFlow (official API)

  • Meta Business verification and display name approval. Plan for hours to days.
  • Templates needed for outbound messages outside 24 hours, with Meta fees.
  • Stable, sanctioned, green tick eligible, safe for broadcasts.

ReplyKit (QR pairing)

  • Scan a QR code and go live in minutes, keep using WhatsApp on your phone.
  • No Meta fees, no templates.
  • Not sanctioned by Meta. Numbers can be restricted. ReplyKit only answers inbound messages, paces replies like a human, enforces caps and never sends campaigns to reduce that risk. Use a dedicated number.
  • We answer "Will my number get banned?" plainly on the home page, and the terms spell out the risk before you connect.

Who should pick which

Choose SleekFlow if you

  • Sell on Instagram and Messenger as much as on WhatsApp.
  • Run broadcasts and campaigns to a customer list.
  • Have a team of 3 to 10 people who need a shared inbox and reporting.
  • Need the official API for compliance or the green tick.

Choose ReplyKit if you

  • Get your leads on WhatsApp and want every one answered in seconds.
  • Book appointments and want them booked automatically, with reminders.
  • Want a working agent today for $29, not a platform project.
  • Are happy to use a dedicated number and accept the pairing risk.

Our verdict

SleekFlow is a platform you build on. ReplyKit is a worker you switch on. If you have a team and several channels, SleekFlow earns its price. If you have a WhatsApp number and unanswered leads, ReplyKit solves that today for a fraction of the cost, and you can add a platform later if you outgrow it. If you want to see the ReplyKit side for yourself, the home page has a live demo you can message right now.

Frequently asked questions

How much does SleekFlow cost in Malaysia?

As of October 2026, SleekFlow's Malaysian pricing page lists Pro AI at RM 449 a month (RM 399 a month billed annually) for 3 users, and Premium AI at RM 1,399 a month (RM 1,199 billed annually) for 10 users. In USD the Pro AI tier is listed at about $139 a month. WhatsApp API hosting and per-message fees are charged separately.

Is ReplyKit cheaper than SleekFlow?

Yes, by a wide margin for WhatsApp-only use. ReplyKit starts at $29 a month with the AI agent included and no Meta fees, against SleekFlow's Pro AI tier from about $139 a month plus WhatsApp API fees. SleekFlow includes channels and features ReplyKit does not have, such as Instagram, Messenger and broadcasts.

Does SleekFlow require the official WhatsApp Business API?

Yes. SleekFlow connects WhatsApp through the official Business API, which needs Meta business verification and carries per-message fees for templates. ReplyKit pairs a normal number by QR code instead, which is faster and fee-free but not sanctioned by Meta.

Which one books appointments in the chat?

ReplyKit has a built-in scheduler, so its agent offers real open slots, confirms the booking, sends a reminder and exports .ics files. SleekFlow handles booking through its Flow Builder and integrations with external calendar tools.
