Sleekflow is social commerce and customer engagement platform. Best suited for e-commerce businesses in Asia-Pacific markets. Known for its strong focus on social commerce and WeChat integration.
Respond.io SleekflowThe respond.io vs SleekFlow decision comes down to seats versus social commerce: Respond.io Growth costs $159/month (annual) for 10 seats with workflow automation and broadcasting, while SleekFlow Pro AI costs $149/month for just 3 users with in-chat catalogs and Stripe 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 ~460 reviews, 2026) provides a visual workflow builder, AI Agents, broadcast messaging, and CRM integrations. SleekFlow (G2: 4.6/5 from ~205 reviews, 2026) provides product catalogs, in-chat payments, and Shopify/WooCommerce integrations.
Both target Southeast Asian and APAC markets where WhatsApp and Messenger dominate. 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 catalogs and payment links. The seat math is the headline trap — SleekFlow's 3-user cap on Pro AI forces a jump to Premium AI at $349/month for a 4th agent, while Respond.io includes 10 seats at $159.

How do Respond.io and Sleekflow compare on features?
Respond.io and Sleekflow compete in the same category but tune their feature sets for different team profiles. The material differences cluster around channel coverage, automation depth, reporting, and team management. The side-by-side below draws on aggregated G2 and Capterra reviews. A flat-rate alternative like Converge ($49/month for up to 15 agents) may sidestep the trade-off entirely.
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.
SleekFlow's commerce features include product catalogs displayed in chat, payment-link generation, Shopify order tracking, and WooCommerce inventory sync. The Flow Builder creates visual automation, but is capped by tier — 5 active flows on Pro AI, 50 on Premium AI (confirmed on SleekFlow's 2026 pricing page). AI-powered replies assist agents. SleekFlow has no email inbox on any plan.
Which has more channels, respond.io or SleekFlow?
SleekFlow technically lists more Asian channels (WhatsApp, Messenger, Instagram, LINE, WeChat, Viber, Telegram, SMS, TikTok), but gates the count — Pro AI connects only 3 channels and Premium AI 10 — while respond.io adds email and SMS that SleekFlow's inbox lacks entirely. SleekFlow adds Instagram and WeChat on lower tiers; respond.io adds a true email inbox (IMAP/SMTP) and VoIP that SleekFlow does not. Neither supports Discord or Zalo at any tier. The practical read: if you sell through chat and need WeChat plus in-chat payments, SleekFlow fits; if you run sales workflows across WhatsApp, Telegram, and email with CRM sync, respond.io fits. If you are weighing respond.io against a help-desk-style platform rather than another commerce tool, our Intercom vs Respond.io comparison breaks down WhatsApp support, AI-resolution pricing, and per-seat versus per-contact billing.
How much do Respond.io and Sleekflow cost?
Respond.io starts at From $79/mo (usage-based); Sleekflow starts at From $149/mo (usage-based). Converge is $49/month flat for up to 15 agents with all channels and AI included.
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 still $159/month (10 seats included); SleekFlow needs Premium AI ($349/month, 5 users) plus paid user add-ons. SleekFlow's free tier (50 contacts, 3 users) is a starting point Respond.io lacks — Respond.io offers only a 7-day trial.
What hidden fees do respond.io and SleekFlow add?
Both stack Meta's WhatsApp per-conversation fees on top of the subscription, but SleekFlow adds a $15/month-per-number hosting charge respond.io does not, and both meter monthly active contacts (MACs) rather than total stored contacts. Confirmed against both vendors' live 2026 pricing pages: SleekFlow Pro AI starts at 500 MACs (add-ons to 2,000) and Premium AI at 1,000 MACs (add-ons to 12,000); a contact only counts once a two-way message happens in a billing month, so stored-but-silent contacts are free. Respond.io's Growth plan includes 1,000 MACs and charges overage beyond that. SleekFlow also gates channel count by tier — Pro AI connects 3 channels and 5 active Flow Builder flows, Premium AI connects 10 channels and 50 flows — whereas respond.io's seat-based tiers don't cap channels the same way. Both advertise annual-billing rates; respond.io's monthly billing runs 25-35% higher (Starter $99, Growth $199, Advanced $349). For a 3-agent team running one WhatsApp number, the all-in floor is roughly SleekFlow $164/month ($149 + $15 hosting) versus respond.io $159/month on Growth — before Meta conversation fees on either side.
