pysftp vs. Paramiko for SFTP File Transfers

When selecting a library for SFTP file transfers, it's crucial to compare pysftp and Paramiko to determine their respective strengths and limitations.

pysftp and Paramiko: Overview

pysftp serves as a wrapper around Paramiko, providing a more Python-friendly interface. It simplifies SFTP interactions, but its API lacks the comprehensive features of Paramiko.

Pros and Cons

pysftp:

• Pythonic Interface: User-friendly interface tailored for Python developers.
• High-level Features: Implements advanced features such as recursive file transfers.

Paramiko:

• Comprehensive Feature Set: Exposes a wide range of low-level features, including advanced authentication methods and proxy support.
• Flexibility: Allows customization of SFTP interactions for specific requirements.

Considerations

• Legacy Status of pysftp: pysftp has not been updated since 2016 and has unresolved issues, particularly on Windows platforms.
• Versatility of Paramiko: Paramiko offers a broader feature set and support for a wider range of authentication methods.
• Development Considerations: Paramiko is actively maintained, making it a more reliable choice for new projects.
• High-level Features: Both libraries provide high-level features, with pysftp excelling in recursive file transfers. However, you can access Paramiko's high-level features via pysftp's Connection.sftp_client method.

Conclusion

If simplicity and ease of use are paramount, pysftp may be a suitable option. However, if low-level customization, versatility, and ongoing support are essential, Paramiko is the preferred choice. Developers seeking a complete solution can combine the high-level features of pysftp with the flexibility of Paramiko by utilizing Paramiko's underlying SFTPClient object.
