Syncthing vs iCloud: What are the differences?

## Introduction
Here are the key differences between Syncthing and iCloud:

1. **Syncing Mechanism**: Syncthing uses a peer-to-peer synchronization model, allowing direct synchronization between devices without relying on a central server. On the other hand, iCloud relies on Apple's cloud servers to sync data across devices, which might raise concerns about privacy and security. 
   
2. **Cross-platform Compatibility**: Syncthing offers cross-platform compatibility, supporting various operating systems such as Windows, macOS, and Linux. In contrast, iCloud is primarily designed for Apple devices, limiting its use on non-Apple platforms. 

3. **Cost**: Syncthing is an open-source software that is free to use without any subscription fees. In comparison, iCloud offers limited free storage and requires a paid subscription for additional storage, which might be a deciding factor for users based on their budget and storage needs.

4. **File Limits**: Syncthing does not impose any file size limits on the data that can be synced between devices, allowing users to transfer larger files seamlessly. On the contrary, iCloud has file size limits for data syncing, which can hinder the sharing of larger files across devices.

5. **Privacy Control**: Syncthing puts a strong emphasis on privacy and security, giving users control over their data by enabling end-to-end encryption. In comparison, iCloud's encryption methods, although secure, are ultimately controlled by Apple, raising concerns about data privacy.

6. **Customization Options**: Syncthing offers advanced customization options and settings, allowing users to tailor the synchronization process according to their specific needs. In contrast, iCloud provides a more user-friendly interface with limited customization options, which may be preferred by users looking for simplicity over customization.

In Summary, Syncthing and iCloud differ in their syncing mechanism, cross-platform compatibility, cost, file limits, privacy control, and customization options.
