Linchpin Cloud waitlist — Supabase

The Linchpin Cloud — early access form on the landing page POSTs directly to Supabase REST. Anon key is exposed in the page (that's the design); RLS on linchpin_waitlist_signups makes the table insert-only from the client.

Current state (2026-05-17): live. Hosted in the flow-rpa Supabase project (dhkpgytpbawinqvpnfsz), shared with Flow infrastructure. Schema applied via supabase/linchpin_waitlist_signups.sql.

Reading the list

The anon key cannot SELECT — that's the point. Reads go through the service-role:

• Supabase dashboard → Table Editor → linchpin_waitlist_signups.
• Or psql with the service-role connection string from Project Settings → Database:

  psql "$SUPABASE_DB_URL" -c "\copy (select email, source, created_at
    from public.linchpin_waitlist_signups order by created_at desc)
    to 'waitlist.csv' csv header"

Re-running the schema migration

supabase/linchpin_waitlist_signups.sql is idempotent — safe to re-apply if you tweak the policy (e.g. via the Supabase MCP's apply_migration or by pasting into SQL Editor).

Migrating to a different backend later

If you move to ConvertKit / Resend / a Linchpin API endpoint, only the two constants in index.html need to change. Existing signups stay in Supabase; export to CSV via the snippet above and import wherever.
