Using Self-Hosted Supabase with V0 instead of Supabase Cloud

(edited)

Hello dear V0 forum,

I’ve been using V0 for a few weeks now and I’m really impressed by the UIs it can generate. For my projects I use Supabase as the backend, but always as a self-hosted option.

Is there a way to connect my own Supabase instance, or does V0 only work with the Supabase Cloud version?

Every time I enter my own Supabase environment variables, it still tries to connect me to the Supabase Cloud version.

Is there any workaround for this, or does anyone know if support for self-hosted Supabase is planned?

Thank you in advance and best regards!

Hi , welcome to the Vercel Community!

Glad to hear you are loving the v0 experience. I'm not aware of Self Hosted Supabase support. But, let me check with our team for you.

Do you already have a self-hosted instance?

Thank you so much for your quick and friendly reply! Yes, I have several self-hosted Supabase instances running on my own VPS servers. For data protection reasons, it’s essential for some of my EU projects that the data can be self-hosted.

I’ve also already tried using prompts where I ask v0 to build the frontend for a Supabase instance, with the idea of later completing the integration using another coding assistant like Claude Code. However, as soon as I mention Supabase in my prompt, it automatically tries to initialize Supabase Cloud.

Hey , how are you doing? I’m monto, part of the v0 team! Thanks for reporting this The idea is that you can use your own env variables. I’m working on a fix to stop asking you to set up the instance if the envs are present. Will let you know when it gets landed!

My work around was to set rules ,telling v0 not to initiate supabase installation and it has worked so far.
