Respond.io vs Sleekflow

Respond.io Growth costs $159/month for 10 seats with workflow automation and broadcasting, while SleekFlow Pro AI costs $149/month for 3 users with social commerce and in-chat payments — both are WhatsApp-centric platforms headquartered in Asia, but Respond.io optimizes for sales automation and SleekFlow optimizes for social selling. Respond.io (G2: 4.8/5 from ~305 reviews) provides visual workflow builder, AI Agents, broadcast messaging, and CRM integrations. SleekFlow (G2: 4.6/5 from ~168 reviews) provides product catalogs, in-chat payments (Stripe/PayPal), and Shopify/WooCommerce integrations.

Both platforms target Southeast Asian and APAC markets where WhatsApp and Messenger dominate customer communication. The key difference is what happens after the conversation starts: Respond.io routes and automates conversations across the sales funnel. SleekFlow converts conversations into transactions with product catalogs and payment links.

Respond.io provides stronger workflow automation and broader channel reach; SleekFlow provides stronger social commerce features — automation-first versus commerce-first messaging platforms. Respond.io's workflow builder creates multi-step automation with conditional logic, wait steps, and API calls. AI Agents resolve queries and qualify leads. Broadcasting sends campaigns to WhatsApp, Messenger, Telegram, LINE, Viber, and SMS contacts. Channels include WhatsApp, Messenger, Telegram, LINE, Viber, email, SMS, and webchat.

SleekFlow's commerce features include product catalogs displayed in chat, payment link generation, Shopify order tracking, and WooCommerce inventory sync. The Flow Builder creates basic automation. AI-powered replies assist agents. Channels include WhatsApp, Messenger, Instagram, LINE, WeChat, Telegram, and webchat — but no email inbox on any plan.

Channel comparison: Respond.io adds email and SMS that SleekFlow lacks. SleekFlow adds WeChat and Instagram that Respond.io lacks on lower tiers. Neither supports Discord or Zalo.

At comparable tiers, Respond.io Growth ($159/month for 10 seats) offers more seats than SleekFlow Pro AI ($149/month for 3 users) — Respond.io includes 3.3x more users for $10 more. SleekFlow's 3-user cap on Pro AI forces teams of 4+ to Premium AI ($349/month, 5 users). A 5-person team: Respond.io Growth = $159/month; SleekFlow Premium AI = $349/month. Respond.io is 54% cheaper.

At 10 users: Respond.io Growth = $159/month (10 seats included); SleekFlow Premium AI = $349/month (5 users) + additional user fees. Respond.io's seat-generous tiers consistently win for larger teams. However, SleekFlow's free tier (50 contacts, 3 users) provides a starting point that Respond.io lacks — Respond.io offers only a 7-day trial.

Both charge Meta's WhatsApp API fees on top of subscriptions. SleekFlow adds $15/month per WhatsApp number for hosting. Respond.io charges contact overage fees when exceeding monthly active contact limits (1,000 on Growth). Both require annual billing for advertised rates.

Choose Respond.io if your primary need is sales automation and workflow orchestration across messaging channels. The visual workflow builder creates conditional routing with if/then logic. AI Agents handle frontline queries. Broadcast messaging reaches contacts on WhatsApp, Messenger, Telegram, and SMS. CRM integrations (HubSpot, Salesforce, Pipedrive) sync conversation data. 10 seats on Growth cover most mid-size sales teams.

Choose SleekFlow if you sell through messaging conversations and need in-chat commerce. Product catalogs display items inside WhatsApp and Messenger. In-chat payment links (Stripe, PayPal) let customers pay without leaving the conversation. Shopify and WooCommerce integrations sync inventory. The free tier (50 monthly active contacts, 3 users) lets small businesses test social selling before committing.

Respond.io is the right tool for sales teams that need workflow automation, broadcasting, and CRM integration across messaging channels with generous seat limits. SleekFlow is the right tool for ecommerce businesses that sell through chat conversations with product catalogs and in-chat payments.

For teams that need messaging-first support across WhatsApp, Telegram, Discord, and Zalo without contact-based or user-based pricing, Converge offers all channels at $49/month flat for up to 15 agents.
