# Facade and libSoftphone

Acrobits provides two types of SaaS SDKs: **libSoftphone** and **Facade**.

- **libSoftphone** is the native Acrobits SDK.
- **Facade**, also known as the wrapper SDK, is designed to simplify interactions between the native SDK and the application.

These SDKs offer different tradeoffs depending on the level of control and integration complexity you need.

## libSoftphone and Facade SDKs comparison

**libSoftphone** provides direct access to Acrobits softphone features, but it requires a more involved integration.
**Facade** provides a simpler interface for developers, but it exposes fewer low-level capabilities.

| | libSoftphone SDK | Facade SDK |
| --- | --- | --- |
| **Key features** | Lower-level APIs | Easy-to-use interface layer |
|  | Rich features | Seamless integration |
|  | Advanced customization | Rapid development |
|  | Deep integration possibilities | Simplified maintenance |
|  | Scalable and flexible |  |
