## When Nodium fits better

- You want a gateway that transports and nothing else: every inbound message goes to your webhook, every reply comes from your code.
- Your customers are in Europe: prices in euros, data hosted in the European Union, erasure by API. See [security](https://nodium.io/en/security).
- You connect your customers' numbers: one key, one client per customer, a [hosted connect link](https://nodium.io/en/features/embedded-signup).
- You want a bill you can predict: overage is billed per 1,000 messages up to a cap you set yourself.
