@dverhey @wenn I have found Transmit to be an honest waste compared to the plethora of FTP applications out there in the wild.
For much less, about 11 dollars less than Transmit, you can get Forklift, which has an amazing interface that is just so compliant with Leopard, and it offers the same idea that Transmit offers, the two pane window. It’s a pretty heavy app though, it has a feature I never quite understood why they would integrate, an application deleter, much like AppZapper and AppCleaner and the like. It still gives you information that no other FTP app will give you easy access too.
i have not used Forklift as a primary FTP client, but have gazed around it and used it sparingly, I recommend it to try
Number 2, Cyberduck like @Bri_L @ryanpowell and @digitaljesus pointed it. It is what I use primarily, its a great app and offers some pretty advances features for a free app, its also open source and is constantly in development and being updated. I love how it transfers files to and from your computer using some kind transfer manager. One thing I don’t like about it though, and AFAIK and seen, don’t quote me on this, is the list view, I was never a fan of list view, I like to see icons, I guess I point this out in Cyberduck because it has somewhat of a finder like window, works a lot like it. It has quicklook for example (ForkLift has quicklook too, but the feel is still slightly different.) Though the app is filled with tons of preferences its almost overwhelming, it should be number one on the list of your FTP apps to try.
This FTP app Flow is quite unknown I see almost no reviews on it, no one barely talks about it, but it has the best UI IMO. Its the most up to Leopard standards I would say out of all these apps. Its also, I would say, the fastest, in two ways, the application itself takes advantage of Core Image so its full of eye candy, and its also, IMO, the fastest as far as communicating with your server, folders open instantly, I do not use it myself, its almost too good to be true, but I do have it on my HD because its just a work of art, there is no doubt about it.
Another App is Fetch
All I have to say about it, is that its the app I used before switching to Cyberduck prime time, boo hoo about it, is that is costs money, for things that freeware, freeware like Cybderduck, can do, and better. and is almost featureless compared to other clients these days.
@dverhey Coda and Espresso both have built in FTP apps, have both apps, though I have not really used them, they look really nice. Judging by the rest of the software, and by judging the Espresso FTP login interface, it looks amazing. Here is a screenshot from Espresso: http://macrabbit.com/espresso/features/browse/ looks pretty plain.
Here on Coda’s page clicking through “Sites” “Files” & “Editor” will give you screenshots of the built in FTP, again, never used it, but looks cool, editing files on the server looks super simple (May I add Cyberduck does too, not sure about Forklift and Flow, but I am sure they do as well).
Here are reviews of FTP apps, this is one of my favorite sites, AppStorm.
Forklift Review
I didn’t mention ExpanDrive as it doesn’t suit me, but it most definitely would suit others, builts FTP into finder (for a price though – a price thats not needed that is :(), ExpandDrive Review
Espresso Review
Coda Review
off topic but to the Coda user, I must recommend reading this 20 Excellent Coda Tips
Here is 10 Mac FTP Apps contains a few i didn’t mention like filezilla (horrible interface @J0E mentioned it), Captain FTP (never used, but looks like it runs on java, boooo) and also NetFinder, looks nice, but the interface looks a mess. Yummy FTP is the same deal as NetFinder, looks nice, but really cluttered
Interarchy 9 haven’t used this one much, but the interface looks promising, have it sitting on my HD.
Holy fuck im exhausted from typing, hope this made sense to any of you :)
