Interakt alternative. Always-on WhatsApp without the Business API.

Interakt is a packaged WhatsApp commerce platform built on top of Meta's WhatsApp Business API. They give you a shared team inbox, a chatbot builder, a catalog integration, and a campaign manager, all sitting on top of the Business API gateway. The value is the packaged product. The cost is everything Meta's Business API bakes into your traffic: business verification, template pre-approval, the 24-hour customer service window, per-conversation pricing, plus Interakt's own per-seat and feature tiers on top.

Mossmoon doesn't use the Business API. Your customer scans a QR with the normal WhatsApp on their phone, a hosted always-on connection runs alongside their device, every message routes through your stack via REST and webhooks. No Meta onboarding, no template queue, no 24-hour window, no per-seat fees, no per-conversation fees. We're a clean developer API, not a packaged inbox. You bring the UI; we bring the connection.

Maybe not for the brand's own number. If you're sending one-to-many transactional messages from your verified business number (order confirmations, shipping updates, COD verifications, cart abandonment) to a large customer list, Interakt's Business API path is engineered for that workload. Templates make sense, per-conversation pricing scales, the verified business profile is the point.

If you're building anything where the customer's own WhatsApp matters (a CRM for your sales team, AI agent on a store owner's line, a multi-tenant SaaS for other brands), Mossmoon's path wins decisively. Many teams run both: Interakt or another BSP for the broadcast lane, Mossmoon for the conversational lane.

Interakt charges a monthly platform fee per business plus Meta's per-conversation pricing on top (rates vary by country and conversation category). Add-ons for advanced features and additional seats are common at higher tiers. Predicting a monthly bill at any scale is genuinely hard because the rate card moves and conversation categories shift.

Mossmoon is flat $15 per active line per month. Unlimited inbound and outbound. No per-conversation fees. No per-seat fees. No per-country rate cards. A line that sends 10 messages costs the same as a line that sends 10,000. First line free for 7 days from when it actually goes ready.

Yes, those are Interakt's UI products. Mossmoon is an API: you build (or already have) the team inbox, the AI agent, the workflow builder. For most teams switching, the inbox and the bot already live somewhere else (HubSpot, GHL, n8n, a custom dashboard, an AI orchestrator) and Interakt's built-in UIs were a side effect of the bundle. If the packaged inbox is the actual reason you're on Interakt, that's a real reason to stay.

If you want a fast inbox UI on top of Mossmoon, agency teams have shipped one over the API in a sprint or two. The webhook contract is small: one POST for outbound, one signed inbound webhook per message.

This is one of the strongest fits. Each client (each store owner, each agent) scans their own QR on a Mossmoon-hosted connect page. Their own WhatsApp number, their own line_id, their own webhook payloads. No Meta business verification per client. No template queues per client. Onboarding is under two minutes per number instead of the days-to-weeks per number you get going through Business API onboarding for each tenant.

Flat $15 per line means you can resell to your clients on a clean agency markup without padding for Meta rate-card volatility.

That's a Meta WhatsApp Business API policy: outbound past 24 hours of silence needs a pre-approved template. Interakt inherits it because they sit on the Business API. Mossmoon doesn't. The connection runs through your customer's actual WhatsApp on their phone, so the rule never applies. Send any message any time, the way a human would type it.

No. Mossmoon doesn't go through Meta Business Manager at all. No documents, no display-name review, no Facebook account requirement. The end-customer just opens WhatsApp on their phone and scans a QR.

Yes, and in a way most agency clients prefer. With the Business API, end-customers see your verified business profile (the green check, the formal display name) and they know they're talking to a business platform. With Mossmoon, end-customers see your client's normal WhatsApp identity, because they're talking to your client's actual WhatsApp account. For sales follow-up, support conversations, AI receptionist on a small business owner's line, this is the natural fit. For mass marketing from a brand, it's not.

The Mossmoon integration is an afternoon: one POST to provision a line, embed the connect URL, listen on one webhook for inbound. The slow part is asking each customer (or each store owner) to scan a fresh QR with Mossmoon's connect page. Because WhatsApp authorization lives on the user's phone and not in either provider's database, there's no backend transfer either side could do.

Most teams batch-message their list, send the connect link, and clear the migration over a few days.
