core-admin VS ActiveAdmin

Like most things, it's probably a combination of things.

The Django Admin existed before Django publicly existed. That meant that once anyone started using Django they knew that they should constrain their use of Django in certain ways so that the Django Admin would work with their usage. Features that would be added to Django would be built with the Django Admin in mind.

Many tools like Flask or FastAPI don't have an opinionated model layer like Django. Without that, you can't really create an admin interface programatically. People could be storing their data in any sort of fashion anywhere. How would one build an admin system for something like Flask or FastAPI where there's no convention around how people set up data access? A lot of frameworks out there don't tell you "access your data in this way" or "this is how users will be authenticated." Without those two things, it's hard to really create an admin system.

There are similar systems available for some frameworks, but since they aren't part of the core framework, they don't get the same attention. Someone creates it, but it doesn't have the kind of community buy-in that sustains it. One of the odd things about Django is that the admin system is under `django.contrib` which indicated that they didn't intend for it to be in the core of Django forever, but that's not really how `django.contrib` ended up. It continued to be a core part of Django maintained as part of the framework.

Like I said, there are admin dashboards available in other frameworks like RailsAdmin (https://github.com/railsadminteam/rails_admin) or Core Admin for .NET (https://github.com/edandersen/core-admin) and I'm sure there's more. However, both Rails and .NET provide most of what Django provides (and a lot more than most frameworks). Rails and .NET both have a default data access ORM that a majority of people using those frameworks tend to use. .NET has built-in authentication/authorization so the admin can work off that. Rails doesn't have auth, but RailsAdmin uses some plugins.

If CRUD only is your goal, there are existing out of the box options such as this: https://github.com/edandersen/core-admin

There are projects in other languages/frameworks like .NET (https://github.com/edandersen/core-admin, https://github.com/serenity-is/Serenity), but nothing quite has the momentum that the Django admin has.

Can you clarify what's the "tremendous value" you're getting out of the Django admin?

At Heii On-Call https://heiioncall.com/ we are using Active Admin https://activeadmin.info/ for Ruby on Rails, which seems quite similar to the Django admin. In my experience, it's mostly useful as a fairly basic read-only view of what's in the database. In Rails, it's so easy to whip together a custom view that we tend to do that, and the Active Admin is nice to have but I wouldn't say "tremendous value".

for those who know [https://activeadmin.info/](https://activeadmin.info/) it uses a file format [https://github.com/activeadmin/arbre](https://github.com/activeadmin/arbre)

Very neat! My first thought was that this was a competitor to https://bullettrain.co/.

Looking into it a bit more, it seems more aimed at building admin panels than whole apps. I guess it competes against tools like https://activeadmin.info/?

We briefly considered migrating to a full-grown Rails admin interface, such as ActiveAdmin, RailsAdmin, Administrate or Avo. We especially liked Avo which is built on a very modern stack similar to ours (Tailwind + Hotwire + ViewComponents). In the end, we didn’t go this route as we found some of the options a bit too restrictive (even though Avo is very flexible) and we did not feel like trying to amend it to our needs. For example, Avo renders forms in a 1-field-per-row layout while we wanted something more similar to the Tailwind UI Stacked form layout. Nevertheless, we found a great deal of inspiration in the Avo code and its design principles.

I second Rails. It's incredibly polished and has really good gems to speed up dev. ActiveAdmin is a great gem if you need to quickly make an admin dashboard. It was useful when I had a small consultancy.

See an example: https://activeadmin.info It provides a fast way to create back office functionality.

I can't speak much about Rails, as I've only played with it. But I've used a lot Django in the past.

Regarding the Django admin (in rails you have ActiveAdmin[1]) think if it just as a glorified database explorer. It is an internal tool for developers, product managers and maybe for your support team. It is in no way thought to be used by end users. Every attempt I've seen to use it as such was a catastrophic failure.

With Django, if you know plain HTML and CSS, with the tools I've mentioned in the comment you're responding to, you can build almost anything... For example, let's say you need a highly interactive client side table.... you can always just attach a Vue or a React component for it by using Unpoly compilers [2].

I'd say this stack is less useful the more your app needs to work fully offline... but if you don't have that constraint... I cannot think of anything that can't be built faster and safer.
