Deploy your Svelte app to Supabase
Step-by-step deployment help for Svelte apps on Supabase. We fix Svelte-specific deployment issues, configure Supabase, and get your app live. From $19.
Svelte issues we fix before deploying
Common Svelte problems that affect Supabase deployments.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: syntax works in components, but manual subscribe() calls in modules need explicit unsubscribe to avoid memory leaks).
Missing form validation
SvelteKit form actions that process submitted data without validating fields, types, or sizes — trusting whatever the user sends.
Supabase deployment issues we check for
Common Supabase problems that break Svelte apps in production.
Row Level Security disabled on tables
AI tools create tables without enabling RLS, allowing any user with the anon key to read, modify, or delete all data in those tables.
Service role key exposed in client-side code
The service_role key bypasses RLS entirely. AI tools sometimes embed it in frontend code instead of restricting it to server-side operations only.
Edge Functions hitting CPU time limits
Supabase Edge Functions have a 150ms CPU time limit on the free plan. AI-generated functions with heavy computation or unoptimized queries hit this limit under load.
Storage policies too permissive
Supabase Storage buckets created by AI have public access enabled or policies that allow any authenticated user to read all files, ignoring per-user access control.

Frequently asked questions
How do I deploy a Svelte app to Supabase?
We handle Svelte deployments to Supabase end to end. Start with our code audit ($19) to identify deployment blockers specific to your Svelte project, then we configure Supabase, fix issues, and get your app live in production.
What Svelte issues affect Supabase deployments?
Svelte projects commonly have unprotected sveltekit server routes and sensitive data in load functions. On Supabase, these combine with row level security disabled on tables and service role key exposed in client-side code to cause deployment failures.
Can SpringCode deploy my Svelte project to Supabase?
Yes. We specialize in deploying Svelte applications to Supabase. We audit your codebase for Svelte-specific issues, configure Supabase correctly, and handle the full deployment so your app runs reliably in production.
What does Svelte deployment to Supabase cost?
Our code audit ($19) identifies all Supabase deployment blockers in your Svelte project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
