# alternatives to copyparty

copyparty compared against all similar software i've bumped into

there is probably some unintentional bias so please submit corrections

currently up to date with [awesome-selfhosted](https://github.com/awesome-selfhosted/awesome-selfhosted) but that probably won't last

# recommendations

* [kodbox](https://github.com/kalcaddle/kodbox) ([review](#kodbox)) appears to be a fantastic alternative if you're not worried about running chinese software, with several advantages over copyparty
  * but anything you want to share must be moved into the kodbox filesystem
* [seafile](https://github.com/haiwen/seafile) ([review](#seafile)) and [nextcloud](https://github.com/nextcloud/server) ([review](#nextcloud)) could be decent alternatives if you need something heavier than copyparty
  * but their [license](https://snyk.io/learn/agpl-license/) is [problematic](https://opensource.google/documentation/reference/using/agpl-policy)
  * and copyparty is way better at uploads in particular (resumable, accelerated)
  * and anything you want to share must be moved into the respective filesystems
* [filebrowser](https://github.com/filebrowser/filebrowser) ([review](#filebrowser)) and [dufs](https://github.com/sigoden/dufs) ([review](#dufs)) are simpler copyparties but with a settings gui
  * has some of the same strengths of copyparty, being portable and able to work with an existing folder structure
  * ...but copyparty is better at uploads + some other things

* `zero setup` = you can get a mostly working setup by just launching the app, without having to install any software or configure whatever
* `a`/copyparty remarks:
  * no gui for server settings; only for client-side stuff
  * can theoretically run on iOS / iPads using [iSH](https://ish.app/), but only the iPad will offer sufficient multitasking i think
  * [android app](https://f-droid.org/en/packages/me.ocv.partyup/) is for uploading only
* `b`/hfs2 runs on linux through wine
* `f`/rclone must be started with the command `rclone serve webdav .` or similar
* `h`/chibisafe has undocumented windows support


## file transfer

*the thing that copyparty is actually kinda good at*

* `upload segmenting` = files are sliced into chunks, making it possible to upload files larger than 100 MiB on cloudflare for example

* `upload acceleration` = each file can be uploaded using several TCP connections, which can offer a huge speed boost over huge distances / on flaky connections -- like the good old [download accelerators](https://en.wikipedia.org/wiki/GetRight) except in reverse

* `upload verification` = uploads are checksummed or otherwise confirmed to have been transferred correctly

* `checksums provided` = when downloading a file from the server, the file's checksum is provided for verification client-side

* `cloud storage backend` = able to serve files from (and write to) s3 or similar cloud services; `╱` means the software can do this with some help from `rclone mount` as a bridge

* `a`/copyparty can reject uploaded files (based on complex conditions), for example [by extension](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-extension.py) or [mimetype](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-mimetype.py)
* `j`/filebrowser remarks:
  * can provide checksums for single files on request
  * can probably do extension/mimetype rejection similar to copyparty
* `k`/filegator download-as-zip is not streaming; it creates the full zipfile before download can start

| undecodable filenames   | █ |   |   | • | • | █ |   | • | • |   |   |

* `webdav` = protocol convenient for mounting a remote server as a local filesystem; see zeroconf:
* `zeroconf` = the server announces itself on the LAN, [automatically appearing](https://user-images.githubusercontent.com/241032/215344737-0eae8d98-9496-4256-9aa8-cd2f6971810d.png) on other zeroconf-capable devices
* `mojibake filenames` = filenames decoded with the wrong codec and then reencoded (usually to utf-8), so `宇多田ヒカル` might look like `ëFæ╜ôcâqâJâï`
* `undecodable filenames` = pure binary garbage which cannot be parsed as utf-8
  * you can successfully play `$'\355\221'` with mpv through mounting a remote copyparty server with rclone, pog
* `a`/copyparty remarks:
  * extremely minimal samba/cifs server
  * netscape 4 / ie6 support is mostly listed as a joke altho some people have actually found it useful ([ie4 tho](https://user-images.githubusercontent.com/241032/118192791-fb31fe00-b446-11eb-9647-898ea8efc1f7.png))

* `unmap subfolders` = "shadowing"; mounting a local folder in the middle of an existing filesystem tree in order to disable access below that path
* `files stored as-is` = uploaded files are trivially readable from the server HDD, not sliced into chunks or in weird folder structures or anything like that
* `db stored in folder` = filesystem index can be written to a database file inside the folder itself
* `db stored out-of-tree` = filesystem index can be stored some place else, not necessarily inside the shared folders
* `existing file tree` = will index any existing files it finds
* `file action event hooks` = run script before/after upload, move, rename, ...
* `one-way folder sync` = like rsync, optionally deleting unexpected files at target
* `full sync` = stateful, dropbox-like sync
* `curl-friendly ls` = returns a [sortable plaintext folder listing](https://user-images.githubusercontent.com/241032/215322619-ea5fd606-3654-40ad-94ee-2bc058647bb2.png) when curled
* `curl-friendly upload` = uploading with curl is just `curl -T some.bin http://.../`
* `a`/copyparty remarks:
  * one-way folder sync from local to server can be done efficiently with [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py), or with webdav and conventional rsync
  * can hot-reload config files (with just a few exceptions)
  * can set per-folder permissions if that folder is made into a separate volume, so there is configuration overhead
  * [event hooks](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks) ([discord](https://user-images.githubusercontent.com/241032/215304439-1c1cb3c8-ec6f-4c17-9f27-81f969b1811a.png), [desktop](https://user-images.githubusercontent.com/241032/215335767-9c91ed24-d36e-4b6b-9766-fb95d12d163f.png)) inspired by filebrowser, as well as the more complex [media parser](https://github.com/9001/copyparty/tree/hovudstraum/bin/mtag) alternative
  * upload history can be visualized using [partyjournal](https://github.com/9001/copyparty/blob/hovudstraum/bin/partyjournal.py)
* `k`/filegator remarks:
  * `per-* permissions` -- can limit a user to one folder and its subfolders
  * `unmap subfolders` -- can globally filter a list of paths

* `audio player » os-integration` = use the [lockscreen](https://user-images.githubusercontent.com/241032/142711926-0700be6c-3e31-47b3-9928-53722221f722.png) or [media hotkeys](https://user-images.githubusercontent.com/241032/215347492-b4250797-6c90-4e09-9a4c-721edf2fb15c.png) to play/pause, prev/next song
* `search by custom tags` = ability to tag files through the UI and search by those
* `find local file` = drop a file into the browser to see if it exists on the server
* `a`/copyparty has teeny-tiny skips playing gapless albums depending on audio codec (opus best)
* `b`/hfs2 has a very basic directory tree view, not showing sibling folders
* `f`/rclone can do some file management (mkdir, rename, delete) when hosting througn webdav
* `j`/filebrowser has a plaintext viewer/editor
* `k`/filegator directory tree is a modal window

* sharex `╱` = yes, but does not provide example sharex config
* `a`/copyparty remarks:
  * `OS alert on upload` available as [a plugin](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/notify.py)
  * `discord » announce uploads` available as [a plugin](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/discord-announce.py)
* `j`/filebrowser can probably pull those off with command runners similar to copyparty

# reviews

* ✅ are advantages over copyparty
* ⚠️ are disadvantages

## [copyparty](https://github.com/9001/copyparty)
* resumable uploads which are verified server-side
* upload segmenting allows for potentially much faster uploads on some connections, and terabyte-sized files even on cloudflare
  * both of the above are surprisingly uncommon features
* very cross-platform (python, no dependencies)

## [hfs2](https://github.com/rejetto/hfs2)
* the OG, the legend
* ⚠️ uploads not resumable / accelerated / integrity-checked
  * ⚠️ on cloudflare: max upload size 100 MiB
* ⚠️ windows-only
* ✅ config GUI
* vfs with gui config, per-volume permissions
* starting to show its age, hence the rewrite:

## [hfs3](https://www.rejetto.com/hfs/)
* nodejs; cross-platform
* vfs with gui config, per-volume permissions
* still early development, let's revisit later

## [nextcloud](https://github.com/nextcloud/server)
* php, mariadb
* ⚠️ [isolated on-disk file hierarchy] in per-user folders
  * not that bad, can probably be remedied with bindmounts or maybe symlinks
* ⚠️ uploads not resumable / accelerated / integrity-checked
  * ⚠️ on cloudflare: max upload size 100 MiB
* ⚠️ no write-only / upload-only folders
* ⚠️ http/webdav only; no ftp, zeroconf
* ⚠️ less awesome music player
* ⚠️ doesn't run on android or ipads
* ✅ great ui/ux
* ✅ config gui
* ✅ apps (android / iphone)
  * copyparty: android upload-only app
* ✅ more granular permissions (per-file)
* ✅ search: fulltext indexing of file contents
* ✅ webauthn passwordless authentication

# briefly considered
* [pydio](https://github.com/pydio/cells): python/agpl3, looks great, fantastic ux -- but needs mariadb, systemwide install
* [gossa](https://github.com/pldubouilh/gossa): go/mit, minimalistic, basic file upload, text editor, mkdir and rename (no delete/move)
* [h5ai](https://larsjung.de/h5ai/): php/mit, slick ui, image viewer, directory tree, no upload feature
