ChatDaddy vs SleekFlow, respond.io, WATI, Gallabox & Superchat: 2026 Comparison

If you sell or support customers on WhatsApp, you have probably shortlisted at least two of these names. They all look similar on their homepages: an AI-powered inbox, automation and broadcasts. The differences only show up in the pricing pages, the channel lists and the fine print.

We compared ChatDaddy with five platforms we are most often evaluated against: SleekFlow, respond.io, WATI, Gallabox and Superchat. Everything below comes from each vendor's own website, pricing page, help centre and changelog as of September 2026. Prices and features change often, and several vendors price by region, so check the vendor's own page before you buy.

1. The six platforms at a glance

Each brand also tells a slightly different story:

• ChatDaddy leads on value: unlimited contacts, WhatsApp Web and the official API in one inbox, and CRM, ticketing and commerce built in.
• SleekFlow is commerce and AI-agent led (AgentFlow), with CRM sync to HubSpot, Zoho and Salesforce on its higher plans.
• respond.io brings chats, calls and emails into one thread, and is aimed at mid-market teams.
• WATI tells a growth story: Google Ads and Click-to-WhatsApp ads feeding straight into WhatsApp conversations.
• Gallabox focuses on AI agents across chat and voice that move customers from lead to booking to payment.
• Superchat leans on GDPR compliance and data hosted in Frankfurt.

2. What every platform already does

Before looking at differences, it helps to know what you get regardless of which one you choose. All six offer:

• The official WhatsApp Business API and WhatsApp Coexistence (keep using the WhatsApp Business app on the same number as the API; Superchat's version is in beta)
• Instagram DMs in the same inbox
• A shared team inbox with assignment and internal notes
• Broadcast campaigns, template management and a no-code flow builder
• An AI chatbot that answers from your own knowledge base (on some platforms only on higher plans or as an add-on)
• Contacts with tags and custom fields
• A public API and connections to automation tools such as Zapier or Make

If a sales page makes a big deal of one of these, remember that the others have it too. The real decision comes down to the sections below.

3. Pricing: what you actually pay for

The headline price matters less than what the price is measured in. Some platforms charge by seats, some by monthly active contacts (MAC), some cap how many people you can broadcast to, and some add a fee on top of Meta's WhatsApp message rates. A plan that looks cheap can become expensive once your audience grows.

List prices from each vendor's public pricing page, September 2026, for monthly billing unless noted. WATI and SleekFlow show different prices depending on your country.

Contact limits are where bills grow. SleekFlow bills by monthly active contacts on every plan, and respond.io does from its Growth plan up. So every new person you message in a month counts, and a large broadcast can push you into a higher tier. WATI and Gallabox don't count contacts but cap how many broadcasts or recipients you can send each month. ChatDaddy and Superchat's paid plans have no cap on contacts. With ChatDaddy, your bill is driven by seats, channels and active chats.

Higher tiers. ChatDaddy's plans go from Mini through Basic ($149/mo, or $119 billed annually) and Pro ($359/mo, or $299 billed annually) to Max ($999/mo, or $799 billed annually, with 5 channels and 15 seats), plus custom Enterprise pricing. Every competitor also offers a custom enterprise tier. See the full breakdown on our pricing page.

4. Channels compared

This is where the platforms differ most. Pick the one that covers the channels your customers actually use.

✓ available · Partial / Beta / Limited release: restricted · — not offered or not found on the vendor's own pages.

Two things stand out. First, ChatDaddy is the only one of the six that connects WhatsApp Web (QR login) as well as the official API. A team can connect a number in minutes without waiting for Meta, then move to the API when it needs approved templates and scale, all in the same inbox. Second, if your customers are on LINE or WeChat (common in Hong Kong and Taiwan) or Telegram, SleekFlow and respond.io cover the widest range.

5. CRM, commerce, AI and integrations

✓ available · Partial: limited, being retired, or via a third party · — not offered or not found on the vendor's own pages.

6. Where ChatDaddy stands out

WhatsApp Web and the official API in one inbox

Every platform here supports the official API. ChatDaddy also lets you connect WhatsApp Web by scanning a QR code, and run both side by side. Small teams can start the same day and move to the API when they need approved templates or large broadcasts.

Unlimited contacts from $59

Mini is $59/month, month to month, with 3 seats and no cap on contacts. You won't be pushed into a higher tier because a campaign reached more people this month.

CRM, ticketing and commerce built in

Deal boards, support tickets with stages and assignees, and an in-chat catalog with orders and payments all come in one product. Every competitor here is missing at least one of these, or relies on a third-party tool to fill the gap.

Built for Southeast Asian sellers

ChatDaddy connects to Shopee, Lazada, Tokopedia, Shopline and Boutir as well as Shopify and WooCommerce, so marketplace orders and WhatsApp conversations sit together.

WhatsApp calling that closes the loop

Make and receive WhatsApp calls from the inbox, with call recording. Missed calls can be marked as called back or resolved, so none slip through.

An AI agent and your own brand

An AI agent trained on your files, URLs and website can answer customers, assign conversations and update contact fields. Agencies can also resell ChatDaddy under their own brand through our white-label program.

7. When another platform may suit you better

No single tool is the right fit for every team. Here is when you might lean elsewhere:

• You need LINE, WeChat, Viber or Telegram. SleekFlow and respond.io cover all four. Superchat covers Telegram.
• Your team lives in HubSpot or Salesforce. The other five offer a native HubSpot integration, usually on mid or upper plans, and four of them offer Salesforce. ChatDaddy connects to these through Zapier or its HTTP request node.
• You want an AI agent that answers phone calls. respond.io, WATI (Astra Voice), Gallabox and Superchat (AI Phone Assistant) offer AI voice agents today.
• Your procurement team has a security checklist. SleekFlow, respond.io and Superchat publish ISO 27001 certification. Gallabox holds a SOC 2 Type II attestation. Single sign-on is available on higher or enterprise plans from several of them. Ask each vendor for its current reports.
• You are a European business that wants EU hosting. Superchat stores data in Frankfurt and is built around GDPR.
• Google Ads is your main acquisition channel. WATI connects Google Ads to WhatsApp conversations as well as Meta's Click-to-WhatsApp ads.

8. How to choose

Work through these questions with your team before booking demos:

1. Which channels do your customers use? If it's WhatsApp, Instagram and Facebook, every option on this list works. If you need LINE, WeChat or Telegram, your shortlist gets shorter.
2. How big is your audience, and how often do you broadcast? Compare unlimited-contact plans with MAC-based and broadcast-capped ones using your real numbers.
3. What does a WhatsApp message really cost? Ask each vendor how they bill Meta's fees: passed through at cost, with a processing fee, with a markup, or on their own rate card.
4. Which features are on the plan you'll actually buy? AI agents, CRM sync and single sign-on are often locked to higher tiers. Check the plan, not just the product page.
5. Where do deals and tickets live? If you don't already pay for a separate CRM or helpdesk, a platform with boards and ticketing built in can replace two tools.
6. Do you sell in chat? Check catalog, order and payment support, and whether your store (Shopify, WooCommerce, Shopee, Lazada) connects natively.
