| ------------------------- | ---------------------------------- | ----------------------------- |
| **Setup**                 | No-code, visual editor             | Requires a server / endpoint  |
| **Best for**              | Non-developers, quick integrations | Developers, custom systems    |
| **Trigger calls**         | Yes (Inbound Zapier)               | Yes (Inbound Custom Webhook)  |
| **Receive results**       | Yes (Outbound Zapier)              | Yes (Outbound Custom Webhook) |
| **Custom headers / auth** | Limited                            | Full control                  |
| **Real-time delivery**    | Near real-time                     | Real-time                     |

Use **Zapier** if you want to connect Atllas to apps like HubSpot, Google Sheets, Asana, or Slack without writing code. Use **Custom Webhooks** if you are building a custom integration or need full control over the data flow.
