Fixed 
Another thing I miss is the hierarchy of classes which let you easily see the inheritance of each class
This is imperative for my work, as I often need to target the parent class in favour of creating exceptions for each individual class.
Definitely would like to be able to use the old site again rather than this one until things are fixed and more polished. There’s just a lot of things, which have been mentioned before, that need to be resolved in order for us to have a better experience using the page.
Other than that, I feel that this was a pretty okay update. And also, some articles/pages still lead to the old site and don’t redirect to the new one. Things such as the Creator Challenge, Remote Functions & Events page. Those are just two of what I’ve found so far. Hope to see this get improved in the coming weeks. 
Edit: Nevermind about some of the pages not being redirected. Didn’t know they would still be on the old site if you Google searched it.
Hey folks
Thanks everyone for taking the time to give us your feedback on the new DevHub. It’s clear from your feedback there are lots of issues and in particular in the API reference section which many of you depend on regularly. We agree also that it would have been valuable to have solicited community feedback on the design before pushing this out. For these reasons we are taking your suggestion to re-enable our API reference section on the wiki while we work through this. You can now visit the old API pages by going to: https://wiki.roblox.com/index.php?title=API:Class. Articles and tutorials will still redirect to the new site, but API pages will not if you are still on wiki.roblox.com.
We really appreciate your patience in the meantime and appreciate any ongoing feedback you would like to share about the new DevHub which we’ll keep up and available. I also want to take a moment to thank CloneTrooper for responding to your questions and feedback post launch. He’s been a great advocate internally for your needs. We’ll keep you posted as we continue to iterate on the new DevHub.

Oh thank heaven
Thanks! I’m glad you guys care about what the community values. It’s unfortunately hard to find that on other platforms. Excited to see what the next iteration of the new site looks like!
Amazing, thanks for making this change. Hopefully the revised variant of the developer hub will not have such issues.
Thanks! Fixed.
Thankyou! This is great and I really hope the current issues can be fixed because the new website is really nice aside from a few small things.
Thanks a ton!
I do hope that the API docs can be sorted out. I’ll be sure to give some insight so that we can get this newer feature rolled out, because it most certainly has promise.
I came up with a way I think would be ideal for displaying the classtype browser. It would be a hybrid of both the system we had beforehand and the new system.
I created an image to depict this idea, as it may be easier to explain or understand through this.
While there are definitely some benefits to this change, there are many downsides.
It should be said that this change seems a lot more beneficial to the newer developer, but in the long run affects the more experienced developer due to varying issues. Many things which made navigation, usage, and understanding easier were provided on the old wiki, compared to how everything is ridiculously spread out now that finding and using things are such a pain that I cannot picture myself using this new system as much as I’ve used the old system,
As many others have said:
- There is so much empty space
- The pages are narrower
- The lack of Instance icons
- No parameters at the top
- The domain is not connected to the official roblox website, but rather a sketchy website with a completely new domain
The list goes on and on… but here are a few things that I personally thought were done poorly:
Parameters
This new website has an awful usage of functions and things of the like which used to have parameters shown with them, but now only have a single function name. While it could be said that they have setup a bad system, they have, in fact, setup an amazing system… just somewhere else.
Almost everywhere with the new hub you will be shown something like this:
But somewhere else in the same hub you can get something like this:
The second is far better than the first, providing parameters, and also creating very little white or empty space.
Font and Coloring
In the hub, the usage of fonts and coloring in one specific area is just horrible… I’m talking about the code blocks. The font on the code blocks is nearly impossible to read, a lot of the text can be misread, for example an O could be seen as a 0, and some of the letters seem as though they overlap other letters.
What can also be seen here is a lime green font on a white background, this is nearly impossible to read without either zooming, squinting, or killing your eyes in the process.
With all of this being said, it is important to note that there are far more issues which can be found in other members’ posts. Overall, this change seems to be more for getting newer players into developing.
Lastly, there does not seem to be a direct link to this new hub on the website, and we cannot even type out the new website’s link without it being filtered.
EDIT: I did not notice an update about how the API is in the process of being changed, but I will still leave this here as my feedback on this new change. And is the domain for real, or is it in the process of being moved to the official Roblox domain so that it doesn’t seem so much like a fake website?
The wiki is sooooooooooo much easier to navigate than the new one. It looks like an actual place to find useful information instead of looking like a google slide presentation with fancy boxes and colors taking up valuable room 
Look, I agree with you completely. However, it has been five days since the Developer Hub was released, and I feel that we’re now all in agreement on how we feel about this update.
I believe that, going forward, it would be far more valuable if we could provide Roblox staff with the information and the constructive criticism they need to fix this critically-important development tool, instead of re-iterating how we feel about this new website.
In the new developer hub it would be extremely nice if there could be an archive containing all the information that the old wiki had. This would make old and new developers happy, allowing people to choose one or the other based on their preference.
I’m not sure if this is worth the engineering effort, given that you can use the Wayback Machine already. If there is an article from the wiki that has not migrated into the new site that you believe has value, please let us know.
I wish the old wiki still just worked as it always did
I’m just trying to look at the list of existing services and I keep getting this.
Also, I don’t like the new API reference, why do I have to click through to an extra page just to see the parameters of a function
and when I do click through, it’s annoying that it’s displayed vertically instead of in the same format that the function is actually used
I’ve literally been using the wiki for 10 years now and it’s very annoying that everything is now different and not displayed in a similar format to how it’s always been displayed. I appreciate trying to make it look nicer and more clean but I wish it was done in a way that feels like a natural transition from how it always has been.
I needed to access that exact same page today, coincidentally. Here is a cached version since it’s impossible to access through any resources provided by Roblox anymore. Would be nice if that page was restored and also provided on the new hub as well (as suggested in one of my previous posts).
