This is incredible! I'm going to play around with this in my docker stack.

Wow.
This works crazy fast and performant. Keep up the incredible work!
Put out some in-depth docker instructions and this will be common use in a month. Good work.
The docker compose file worked great for me.
They may have patched it. I'll check it out thanks.
Yup, I tried to run the docker image with the suggested docker command and it errored out for lack of a config file (though it did offer a fix in the logs for mounting the current directory as read/write)
Agreed.
You made this on your phone on the bus ride to and from work.
I cleaned the cat box yesterday and considered that an accomplishment.
Fuck.
Congrats on the cat box cleaning!
I played around with copyparty and I have to say it is just awesome! The config is just fun to mess around with and everything feels snappy.
But I ran into an issue with FTP (probably just something I configured incorrectly) and could not find a discussion for that. I should probably start an issue on Github but as a non-developer I'm not sure how to do that in the correct way.
Edit: I managed to "solve" the problem. Apparently the user uploading to a subfolder over FTP needs the move permission for the folder above said subfolder.
Is there a way to help translate the UI.
I would like to help translate it into Danish.
Would also be willing to help translate the UI.
I bumped into copyparty the other month when looking for a software that could let me transfer files to a friend with the ability to pause/resume. Didn't bother with it, tried another software instead. Never really got it to work so I gave up on it.
Bumped into the YouTube video today, decided to give copyparty a shot, damn sir you've written a fine piece of software. It's so easy to get up and configure. The UI is a bit janky, but charming at the same time. Thanks for all the hard work!

This is insane. I think I'd use ten different applications and still not cover these features. And I can host this. Using a single python file.
Holy shit this is so unbelievably full featured it's not even funny. This is going to rattle some big names. I wonder how long till they try to shut it down because it's better than anything commercially available.
I haven't even tried it yet, but just from the video you can tell it's going to be insanely good. I'm so impressed.
It's the first bit of software I've seen in a long time where I took one look and immediately thought "Fuck me, I need that!"
I use Unraid for my NAS server and just on the off-chance I checked the Unraid community 'app store' and someone's already created a Docker definition for it, published just today! The hype is real
I'll be giving this a shot
The fact you mention security features, without ever saying it's 'super secure' tells me you know a lot about what you're doing. I'm so sick of apps like this that start with "most secure app on the net" but you know they're delusional. Thank you, going to check this out.
so uhh, sorry for the late response to this -- was going to reply much earlier, but then suddenly it became more timely than ever...
the good news is, I'm fairly confident in how it handles the filesystem and permissions, preventing unauthorized access to files.
but the part I'm a bit less sure about is sanitizing user data; the kind of vulnerabilities where someone uploads a malicious file and bad stuff happens if you then open that file in a certain way, or someone sends you a malicious link and trick you into clicking it -- in other words, the kind of vulnerabilities which require the attacker to have a certain level of access already, or that requires tricking you into doing something.
...and with version 1.18.5 released just now, we got a prime example of exactly one of those. Really unfortunate timing, but it's a blessing to have so many new and curious eyes on it to spot these sooner rather than later. It is what it is.
Thanks for making the video but also for providing non Youtube link. Maybe there is a PeerTube server that would enjoy hosting it.
Ho... Ly... Shit... This is great! The UI is a bit confusing at first but doesn't take long to get what's going on. I might even be disappointed with a UI revamp 😁 I can't believe how much functionality this has. It's already replacing some processes I have for mounting drives and backing up files. Maybe I missed something, but my only complaint would be the lack of an automatic one-way folder sync in the Party UP! app.
I'm blown away, great job!
That "functional but charming" UI reminds me of audiobookshelf with the soundleaf app - same vibe where it dosn't look fancy but gets the job done better than most polished alternatives!
Well done! This is exactly what I've been looking for! And it's fun to use and has an aesthetic that reminds me of browsing ftp servers back in the day. And these themes?! I love the whimsy mixed with actual usability.
And its a damn good file server so far: fast, easy to use, makes reasonable security choices, and accessible in the ways I want (rclone mount)
Everyone loves CP. Tell all your friends about CP.
Every single time I have seen one of your comments, you have disappointed me

Don't believe it. This is easily too good to be true.
I have a question, and I want to emphasise thar this is not criticism but a request for dive into technicalities.
In the video you mentioned copyparty has an one-way sync tool. Is there a good reason why it's not two-way, or is this just something you weren't motivated to do?
No worries, good question :>
The problem with bidirectional filesync is that it's an absolutely massive can of worms, very easy to mess up, and the consequences of messing up are usually the worst kind (loss of data). There's an insane amount of edgecases to keep in mind, and you need to get every edgecase right every single time, otherwise you might wipe someone's vacation photos, or suddenly downgrade someone's keepass database to an older version... And stuff like syncing multiple devices to the same server makes it balloon further.
I've started becoming more confident in copyparty's filesystem-index database, but it's still just a hint/guideline, with the filesystem being the only source of truth -- it's still not something I'd trust with tracking sync-state against one or more clients.
The bigger guys who offer bidirectional sync (nextcloud, syncthing, etc.) have spent years perfecting their logic, so I'd like to leave this in their capable hands.
Sync is one of those things that seems like it should be trivial but is actually super complicated.
Thank you for your answer! Do you think copyparty would work together with Syncthing on the same backing directory, or would they compete for changes etc? Copyparty in this scenario would be for sharing content with friends and occasional remote upload
that should be totally fine, I think a lot of people are doing that :>

The video are amazing. It's entertaining and explains everything so it's easily understood.
Oh my gawd what a README!! I'm on my phone and I was trying to scroll back to the top of it from the bottom and I just kept on scrolling... Holy shit I'm going to put this on my kanban board give it proper attention
At this rate might be faster to read code than a read me. Or convert to a wiki style if this much details are really needed.
Look cool! I think you should consider putting a screenshot of the UI somewhere near the top of the README

Guess I'm setting up a locally hosted file server in the near future.
Thank you so very much. I needed to transfer some files locally yesterday and didn't have a NAS set up. So I thought I would quickly set up a samba share on my pop-os media server so my spouse (windows) and I (mint) could swap/store files on the fly in the future. It took me 25 minutes and I almost gave up because my config file was having issues.
This looks sooooo much nicer. May every road rise up to meet you
I would add PairDrop to your list to have bookmarked. It's completely web-based so no download required and thus fully cross-platform. It also works across different networks (i.e. over the internet) by pairing devices or creating a room. Basically Apple AirDrop, but universal and on steroids.

I see flake.nix, i install.
Have been playing around with it for a bit and it's AMAZING.
This is cool. Idk if it’s just me but the h.264 version of your video has no sound!
man... that's really unexpected, I went with h264+mp3 which should be the most conservative / broadly-supported combination you could possibly use, yet still (ﾉ ﾟヮﾟ)ﾉ ~┻━┻
what webbrowser / device / player are you using?
This is me browsing slrpnk.net using the voyager app,on iOS latest version on iPhone 14 Pro, it then opens it in whatever built in player the app uses. Other versions work fine though. This app has me excited as I consider starting self hosting!
awesome thanks, should be able to reproduce it then :>
Haven't looked at the project yet, but that's just the greatest name for a fileserver...
Very sleek project. The language switcher bit was brilliant hahaha. Seriously, good job.
