Rails Admin reflects your models. It cannot reflect a workflow.
Rails Admin inspects your ActiveRecord models and produces an admin without you writing much at all, which makes it an easy first back office. It is also the ceiling: the interface mirrors your schema, and anything shaped like a process rather than a table needs building elsewhere. Jet Admin generates both from the same database.

The verdict
So, which should you choose?
Both can generate an app from a prompt. The difference is what happens next — who can use it, how you govern it, and whether it runs on your real data. Lovable is great for spinning up a brand-new web app with an AI prompt and a fresh Supabase backend. Jet Admin is built for the opposite job: putting governed apps and internal tools on top of the data your business already runs on.

You want built-in permissions and no per-seat pricing

Bring it into Jet.
Full control over your code, none of the deployment headaches. Jet gives you a safe place to deploy, govern, and run your apps. Just export your React app's code and import it in.
Frequently asked questions
What is the difference between Rails Admin and Active Admin?
<p>Rails Admin auto-generates the interface by reflecting on your models with almost no configuration. Active Admin asks you to declare each resource in a DSL, which gives more control and more work.</p>
Is Rails Admin safe for production?
<p>It is widely used in production, but it exposes your schema directly, so it is best kept behind authentication and limited to trusted internal users.</p>
Can Jet Admin replace Rails Admin?
<p>For the screens other people use, yes. Jet connects to the same Postgres or MySQL and generates the interface, with permissions that reach individual rows.</p>
Do I have to migrate my data?
<p>No. Jet queries your existing database in place and never keeps a second copy.</p>
Can I self-host?
<p>Yes. Jet runs on Jet Cloud, in your own cloud account, or fully on-premise on the Enterprise plan.</p>
