Looking for a CMS to manage REST API for data viz site

I am in the planning stages for a data visualization site. Basically the front end would be responsible for rendering the data. I am probably going to use nuxt for this.

The backend however is where I am stuck. Originally I was just going to use supabase as the db and plug it directly into nuxt.

However, there will be researchers who will need to update the data on a regular basis and configure how it will render on the front end. While setting this up in supabase is doable, I am concerned it’s a bit too low level for researchers to manage https://mobdro.bio/ .

I am now looking for a headless cms that manages the api for the front end (also the researchers want the raw data output via a REST API for other researchers and sites to use).

I’ve read about sanctum, which seems to be the tool I’d use as a developer to accomplish this. But it doesn’t solve the issue of needing a CMS.

I’ve checked out Statamic but it doesn’t seem to be a good fit. I’ve also looked into making a CMS with Breeze + Inertia but again looking to avoid that.

Is this something laravel nova is made to address? I wish there was a free version that I could try out to know for sure before buying a license.
