General

  • Language: English or French.
  • Updates: manual check and installed version. Updates are signed and install in one click.
  • Double-click action: for each pane, transfer the file or open it in an editor.
  • Editor per extension: for example map .php to VS Code and .md to another editor. An opened remote file is uploaded back to the server every time you save.

Transfer performance

Defaults suit most servers. On a fast link, increase:

  • concurrent files (overall, per session and per server);
  • fair scheduling between servers, so one large batch doesn't hold up the others;
  • SFTP concurrency and chunk size, or the number of extra FTP connections.

Local transfer log

A redacted JSONL log (no secrets) is kept on your computer only, with automatic rotation. You can export it for troubleshooting, open its folder or clear it.

Native engine

Since version 0.22, SSH, SFTP, FTP, FTPS and S3 transfers run through a native engine written in Rust: a lighter installer and lower memory use.
