# SleekFlow alternatives, compared on what the AI costs

> Six SleekFlow alternatives compared on what the AI costs and how it's billed: respond.io, WATI, Interakt, AiSensy, Manychat and Aivastark, with sourced prices.

SleekFlow is an omnichannel inbox for WhatsApp, Instagram and more, with Flow Builder journeys, and AI agents from its Pro plan. If you're looking elsewhere, the right alternative depends on the job: sending campaigns, a sales team working chats by hand, or letting an AI answer. Here are six, with figures from each vendor's own pricing page.

## What is the best SleekFlow alternative?

It depends on the job. For a sales team that works chats, calls and email by hand, respond.io, from $99 a month. For WhatsApp campaigns, WATI from $69 a month, Interakt from $55 with unlimited agents, or AiSensy, which has a free plan with the WhatsApp API. For Instagram comment-to-DM, Manychat from $17. If the job is an AI answering customers, Aivastark includes 5,000 AI credits in its $39 Starter plan.

### Aivastark (our product)

**Best for:** An AI that answers customers, included in a flat plan

- The AI replies come with the plan: Starter at $39 a month includes 5,000 AI credits and answers on your website, WhatsApp, Instagram, Messenger, Telegram and email, in 80+ languages with Arabic among them, then hands off to your team. The website chatbot has a free plan.
- Watch for: It sends no broadcasts or template campaigns, has no phone line and no Dubai office. If those are the job, pick a tool above.

## When to stay with SleekFlow

SleekFlow is the stronger choice when campaigns, many channels and a local presence are the job. Stay if you:

- You send WhatsApp broadcasts and run Flow Builder journeys
- You want a Dubai office, prices in dirhams and UAE data residency
- You need WeChat, LINE, Viber, TikTok or SMS in one inbox

## The bill none of them remove: Meta's message fees

Every tool here runs on Meta's WhatsApp Business Platform, and Meta charges for business messages whichever one you pick. SleekFlow takes them from a prepaid wallet, WATI, Interakt and AiSensy resell the message fees, respond.io passes them through at cost, and with Aivastark Meta bills your own WhatsApp Business account directly.

**In the UAE.** SleekFlow has the strongest local presence of these: an office in Dubai's DIFC, prices in dirhams and UAE data residency options. Aivastark answers in Arabic and English on WhatsApp, Instagram and your website, without a UAE office or phone line. See [AI customer support for UAE businesses](https://www.aivastark.com/uae).

**WhatsApp fees in the UAE.** Meta prices WhatsApp messages by the customer's country and the kind of message. Our UAE guide lists Meta's current per-message rates in dirhams and dollars, and how each kind of tool passes them on. See [WhatsApp Business API pricing in the UAE](https://www.aivastark.com/uae/whatsapp-business-api-pricing).

## How this list was made

1. These are the products people weigh SleekFlow against for WhatsApp and social inboxes, and each has a full head-to-head on this site with every figure sourced.
2. Prices come from each vendor's own pricing page and carry the month they were checked. They change, so check the vendor's page before you buy.
3. We make Aivastark. It's listed last, and every card says where another tool is the better choice.
