Supabase integration
Write each submission straight into your Supabase Postgres database
Write each submission straight into your Supabase Postgres database
Connect Halloform to Supabase and every submission becomes a new row in the Postgres table you choose. Your form data lands in a real relational database you can query with SQL, expose through the Supabase API, or join against the rest of your app. No glue code required.
Submissions insert directly into your table, ready for SQL queries and joins across your data.
Data lives in your own Supabase project, under your row-level security and access rules.
Surface responses instantly through the Supabase client libraries and auto-generated APIs.
Map each field to a column in your chosen table during setup, and Halloform inserts a matching row per submission.
Use your project's new publishable key (sb_publishable_…) with a Row Level Security policy that only allows INSERT on the target table — least privilege, so even a leaked key can do nothing but add rows to that one table. Avoid the secret key (sb_secret_…): it bypasses RLS and grants full database access. Legacy anon / service_role JWT keys still work. Whichever you use is stored encrypted and only used to insert submissions.
Build a form with Halloform, connect Supabase, and let every submission flow where it needs to go — automatically.
