Deploy Your Supabase Frontend
Supabase handles your backend. ZeroDeploy hosts your frontend. A clean split.
Last updated: February 20, 2026How it works
Supabase backend + ZeroDeploy frontend.
Supabase runs your database, auth, and API in their cloud. Your frontend — a React, Vue, or Svelte SPA — connects to Supabase via their client library. ZeroDeploy hosts that frontend on a global edge network, serving your static files fast while your app talks to Supabase's API at runtime.
Deploy in 3 steps
From zero to live in under a minute.
Create your frontend project
Scaffold a new project with Vite. Add the Supabase SDK and connect it to your backend.
npm create vite@latest my-app -- --template reactBuild for production
Run the build command to generate static output in dist/.
cd my-app && npm run buildDeploy to ZeroDeploy
One command to push your frontend to the edge. It's live in seconds.
zerodeploy deploy --dir distConfiguration tips
Connecting your frontend to Supabase.
- Store your Supabase URL and anon key as environment variables:
VITE_SUPABASE_URLandVITE_SUPABASE_ANON_KEY. These are safe to expose in the client — Row Level Security protects your data. - Initialize the Supabase client once and export it:
createClient(import.meta.env.VITE_SUPABASE_URL, import.meta.env.VITE_SUPABASE_ANON_KEY). - Build your app locally with
npm run buildbefore deploying. Environment variables are baked into the bundle at build time.
Things to know
Supabase-specific tips to avoid common pitfalls.
- The Supabase
anonkey is meant to be public. It works with Row Level Security (RLS) to protect your data. Never expose yourservice_rolekey in frontend code. - Supabase Auth redirects need your deployed URL. After deploying, add your ZeroDeploy URL (e.g.,
https://myapp.zerodeploy.app) to your Supabase project's allowed redirect URLs in the dashboard. - If your app uses client-side routing (React Router, Vue Router), create a
public/_redirectsfile with/* /index.html 200so deep links work. Learn more about redirects → - Real-time subscriptions and storage work client-side — no server needed. Your static frontend handles everything through the Supabase JS client.

Frequently asked questions
Can I deploy a Supabase app on ZeroDeploy?
Yes. ZeroDeploy hosts your frontend (React, Vue, Svelte, etc.) while Supabase handles your backend (database, auth, storage). Your frontend connects to Supabase's API at runtime — no server required on the hosting side.
Is the Supabase anon key safe to expose in my frontend?
Yes. The anon key is designed to be used in client-side code. It works with Row Level Security (RLS) policies that you define in your Supabase dashboard. Never expose the service_role key in frontend code — that bypasses RLS.
Do I need a server to use Supabase with ZeroDeploy?
No. Supabase provides a full backend (database, auth, real-time, storage) accessible via client-side JavaScript. Your ZeroDeploy-hosted SPA connects directly to Supabase's API. No server, no serverless functions needed for most use cases.
How do I handle Supabase Auth redirects after deploying?
Add your ZeroDeploy URL to the "Redirect URLs" list in your Supabase project settings (Authentication > URL Configuration). Include both your subdomain URL and any custom domains you've added.

ZeroDeploy hosts frontends for any backend-as-a-service.
