# Platform matrix

> All twelve platforms side by side: channel, audio, timestamps, delivery, retries.

Twelve systems we read conversations from, and what each one gives us. The left column is the adapter name, which is the word that goes in your webhook URL. [Each platform also has a page of its own](/platforms)

| | |
|---|---|
| bolna | voice · audio · second timestamps · webhook · retries |
| crisp | chat · audio · millisecond timestamps · polled by us · no retries |
| elevenlabs | voice · audio · second timestamps · webhook · retries |
| gupshup | chat · no audio · millisecond timestamps · webhook · retries |
| intercom | chat · no audio · second timestamps · polled by us · no retries |
| messenger | chat · audio · millisecond timestamps · webhook · retries |
| retell | voice · audio · millisecond timestamps · webhook · retries |
| sunco | chat · no audio · millisecond timestamps · webhook · retries |
| twilio | chat · audio · second timestamps · webhook · retries |
| vapi | voice · audio · millisecond timestamps · webhook · retries |
| wati | chat · no audio · second timestamps · webhook · retries |
| whatsapp_cloud | chat · audio · second timestamps · webhook · retries |

## What the words mean

| | |
|---|---|
| voice, chat | Whether the platform carries calls, typed messages, or both. |
| audio | The platform hands us the recording, so a score can rest on how something was said and not only on what the transcript holds. |
| millisecond, second timestamps | How finely the platform times a turn. Seconds are enough for a reply time and too coarse to order two turns that landed in the same second. |
| webhook, polled by us | A webhook platform pushes each conversation to us as it finishes. A polled one is read on a schedule, so it arrives minutes later. |
| retries | Whether the platform sends a delivery again after a failure. Where it does not, a delivery we miss is gone, so an import fills the gap. |

> The generic contract is not on this list. It is the shape you post from a stack of your own, not a platform we read, and it has its own page.
