Omnichannel inbox software:
the alternatives, compared

Every tool here puts customer messages from several channels into one shared queue. They differ in which channels they actually connect, whether an AI answers for you, and how they charge per seat.

What to look for

  • The channels your customers really use. Zalo, Facebook comments, WhatsApp and Instagram are each supported by some tools and not others — check the exact list, not the word "omnichannel".
  • Whether the AI is included or an add-on, and what it answers from: your documents and product catalogue, or a fixed FAQ.
  • How a person takes over from the AI mid-conversation, and whether the same customer is recognised across channels.
  • How the price grows: per seat, per contact, per conversation, or by usage.

Frequently asked questions

A single place where messages from several channels — Messenger, Zalo, WhatsApp, Instagram, website chat, email — arrive in one queue that a team works together, instead of each person watching a different app.

Support for Zalo varies a great deal: the Vietnamese tools on this list are built around it, while most international inboxes do not connect it natively. 2pm.space connects personal Zalo accounts by QR code today, with Zalo Official Account coming soon.

Every feature of 2pm.space is free, with no seats and no plans. What you pay for is the AI your agents use to answer, at the model provider's own rate plus a flat fee when you add credit.
