supabase-export is the definitive answer to “how do I export all my Supabase data?” — paginated export of every table, with a direct importer into any Postgres target: self-hosted Supabase, Neon, Railway, RDS, or local.

​
Install

# Run without installing
npx @nometria-ai/supabase-export export --url https://your-project.supabase.co --key eyJ...

# Install globally
npm install -g @nometria-ai/supabase-export

# Or as a dev dependency
npm install --save-dev @nometria-ai/supabase-export

​
Export from Supabase

# Export all tables to ./supabase-export/ as JSON
supabase-export export \
  --url https://your-project.supabase.co \
  --key eyJ...service-role-key...

# Export specific tables only
supabase-export export --url ... --key ... --tables users,posts,comments

# Export as SQL INSERT statements
supabase-export export --url ... --key ... --format sql

# Bundle all tables into a single file
supabase-export export --url ... --key ... --bundle
Use your service role key, not the anon key. The anon key cannot read all tables.

​
Import into any Postgres

# Import into any Postgres target (Neon, Railway, RDS, self-hosted Supabase, local)
supabase-export import \
  --dir ./supabase-export \
  --target postgresql://user:pass@host:5432/db

# List available export files before importing
supabase-export list-local --dir ./supabase-export
