One inbox.WhatsApp. Facebook. Instagram. Web chat.

Your team switches between 4 apps to answer one customer. That ends today.
Every business using WhatsApp Business, Facebook Messenger, and live chat for customer support faces the same hidden cost: message routing chaos. When agents work across separate platforms, messages go unseen for hours, customers receive contradictory replies from different agents, and conversation history is lost the moment a team member switches tabs.
According to OmniChatStack usage data, businesses running fragmented messaging tools take an average of 3.8 hours to respond to a first message compared to just 22 minutes for teams using a shared inbox.
OmniChatStack is a unified shared inbox that connects your WhatsApp Business API account, Facebook Messenger page, Instagram business profile, and web chat widget to a single agent workspace.
Unlike Freshdesk or Zendesk, OmniChatStack was built from the ground up for businesses where WhatsApp is the primary customer contact channel — not an add-on. No per-seat pricing. No months-long implementation. No enterprise contracts. One flat plan, one inbox, live in minutes.
Everything You Need to Support Customers
Powerful features to help you provide exceptional customer support across all channels.
Omnichannel Support
Connect with customers on Facebook, WhatsApp, Instagram, Twitter, SMS, and email from one platform.
AI-Powered Responses
Intelligent AI assistants that understand customer intent and provide accurate, helpful responses
Analytics & Performance Insights
Track first response time, resolution rate, agent productivity, and customer satisfaction scores across every channel from one dashboard. Set SLA targets, identify bottlenecks, and see exactly where your support operation is losing time.
Real-Time Multi-Agent Chat
Multiple agents handle conversations simultaneously from one WhatsApp number or Facebook page — with automatic collision detection that prevents two agents replying to the same thread. Presence indicators show who is active, typing, or away.
Enterprise-Grade Security
All customer conversation data is encrypted in transit and at rest using AES-256. OmniChatStack is hosted on infrastructure with 99.9% uptime SLA, role-based access controls, and full audit logs for every agent action..
Team Collaboration & Assignment
Assign any incoming message to a specific agent, team, or department with one click. Add private internal notes visible only to your team. Set conversation statuses, labels, and priorities — all without the customer seeing any of it..
How It Works
Connect your channels
Link your WhatsApp Business API account, Facebook Page, Instagram profile, and web chat widget in under 5 minutes. OmniChatStack handles all API authentication — no developer required. All six channels connect from a single settings screen.
Invite your team
Add agents and assign them to channels, teams, or queues. Set permissions, working hours, and auto-assignment rules so every message reaches the right person automatically — even across time zones.
Reply from one inbox
Your team sees every message from every channel in one real-time inbox. Reply to a WhatsApp thread, a Facebook DM, and an Instagram comment from the same screen — with full conversation history and customer contact details always visible.
PRO TIP
After connecting WhatsApp, the most impactful next step is setting up AI autoreplies for after-hours messages. See our WhatsApp Automation Setup Guide.
