whatsappx.si or respond.io?

Who is respond.io for?
As of October 2026, respond.io describes itself as an AI-powered customer conversation platform that brings WhatsApp, TikTok, Instagram, Facebook and email into one team inbox, with workflows, AI Agents, broadcasts and calling (respond.io). It shows a Meta Business Partner badge and connects WhatsApp through the official WhatsApp Business Platform (respond.io features).
It fits B2C sales, marketing and support teams that talk to customers on several channels and want mature automation on top. For example, a retailer answering Instagram DMs, Messenger and WhatsApp from one queue would get a lot from it.
A number already on the WhatsApp Business app can join through WhatsApp Coexistence, which keeps the app working but does not import history (respond.io Help).
Who is whatsappx.si for?
whatsappx.si is for teams whose customer conversations live mainly on WhatsApp and who want to start with the number they already use. Scan a QR code from the WhatsApp or WhatsApp Business app, the number becomes a linked device (the same feature WhatsApp Web uses), recent chat history syncs in, and everyone on the team can reply from one browser inbox at the same time.
On top of the inbox you get:
- Teams and roles. Owner, admin and agent roles, email invites, chat assignment, unread counts and live updates; agents see only the chats assigned to them.
- Keyword automations. Auto-replies triggered by keywords, which you can switch on or off and track with run counts. AI replies to customers are coming soon and are not available yet.
- Knowledge base. Write articles once, and teammates can search them to find answers quickly.
- Official API as an extra option. Connect numbers through Meta's WhatsApp Business Platform with Embedded Signup and sync message templates. We recommend this route for high volume, templates and automation at scale.
- REST API for developers. API keys, outbound webhooks for incoming messages and in-app API docs, for connecting your own systems or CRM.
For example, a two-person clinic front desk could link its existing number and reply to patients together from one inbox.
How does pricing work on each?
respond.io (as of October 2026, from respond.io/pricing) publishes USD prices with users and Monthly Active Contacts (MAC) as the main levers:
| Plan | Billed yearly | Month-to-month | Included |
|---|---|---|---|
| Starter | $79/month | $99/month | 5 users, unlimited MACs |
| Growth | $159/month | $199/month | 10 users, from 1,000 MACs |
| Advanced | $279/month | $349/month | 10 users, from 1,000 MACs |
| Enterprise | Custom | Custom | Unlimited users |
Extra users and MACs cost more. Broadcasts, workflows, AI Agents and the Developer API start at Growth; webhooks and SSO need Advanced. WhatsApp's fees are paid separately from a prepaid balance at Meta's rates with no markup (respond.io Help).
whatsappx.si has plans for USA (USD) and India (INR); see the pricing page. A QR-linked number has no Meta per-message fees, because it is a linked device of your own WhatsApp or WhatsApp Business app, which Meta describes as free to use (WhatsApp Business FAQ). A number on the official WhatsApp Business Platform is billed by Meta per delivered message, by message category and the recipient's market (Meta pricing documentation).
How do you switch from respond.io to whatsappx.si?
Decide which connection you will use
If your number is on the official WhatsApp Business Platform through respond.io, ask respond.io support how to disconnect it before you connect it to whatsappx.si through Meta Embedded Signup. If the number lives on the WhatsApp or WhatsApp Business app, link it by scanning a QR code.
Export what you need from respond.io first
whatsappx.si does not import respond.io conversations, contacts, workflows or broadcasts. Export what you must keep before you cancel. With QR linking, recent chat history on the phone syncs in; with the official API, plan on starting from new messages.
Rebuild automations in a simpler form
respond.io workflows and AI Agents have no direct equivalent. Recreate the essentials as keyword auto-replies, move reference answers into the knowledge base for your team, and use the REST API and webhooks for your own systems or CRM.
Invite the team and set roles
Create a workspace, invite teammates by email, and set owner, admin or agent roles. Run both tools side by side for a few days before you cancel.
