Polymorfa vs WhatsApp inbox apps

Inbox apps give a team a finished place to answer chats. Polymorfa gives developers the API underneath, to build an inbox, CRM, bot or any other product their own way.

The layer under the inbox.

BotConversa, Whaticket, TimelinesAI and Rasayel sell the top layer: an inbox, CRM and bots, priced per seat or per plan.

Polymorfa is the layer underneath. If you are building your own inbox, CRM or vertical product, you get numbers, messages, calls and webhooks, and you design the screens.

PolymorfaNumbers, messages, calls, webhooks, health

WhatsAppLinked device and Cloud API

Inbox platforms sell the top layer to end teams. Polymorfa is the layer under it, for companies building their own.

Calls

Calls your product can answer.

TimelinesAI logs calls when they end. Rasayel lists voice calls as coming soon. With Polymorfa, your product receives the call, answers it in a browser or on a server, and keeps the call history.

Browser

Server code

SIP / PBX

Answer in a browser, from server code that reads and writes the audio, or on your own PBX over SIP. The same webhooks follow every call.

Customers

Built for serving many businesses.

The Customers API gives each of your clients their own numbers, pairing links and scoped access. Webhooks are signed, so your backend can verify every event.

TimelinesAI states that its webhook requests carry no authentication.

Fair comparison

When to buy an inbox app instead.

If your team needs to answer WhatsApp chats and you are not building software, buy an inbox app. Polymorfa has no agent inbox, CRM pipeline or built-in AI replies.

These apps include onboarding help, reporting and assignment for your agents. With Polymorfa, you build those.
