Provider Reference ​

Technical reference for the storage protocols and providers documented on this page, grouped by connection type. This page is a selection, not the catalogue: Blomp, GitLab, native Backblaze B2, Immich and Drime are supported too and have their own pages.

AeroFTP v4.2.1 supports 7 transport protocols, 26 native provider integrations and 47 pre-configured presets, reaching 56 providers over 70 connection methods. Those figures are generated from the code into docs/PROVIDER-INVENTORY.json (at the v4.2.1 tag) and CI fails when they drift, so quote them from there rather than counting the tables on this page.

suppaftp Pin

Since v4.2.1 the FTP library is suppaftp 12.1.0 (from 10.0.2), pinned to a forked release commit, whose control replies are capped at 256 KiB. The move fixed implicit-FTPS transfers against vsftpd: AeroFTP now asks for protected data connections after login. Earlier versions pinned =8.0.3 to keep the FTP layer stable across Linux, macOS, and Windows.
