Comparing prices across every provider we track...
Heroku Postgres · $0/mo (1536 GB RAM, 192 vCPU, 102400 GB)
Heroku's Advanced 1536G-Performance tier pricing is opaque and requires sales contact, making direct comparison impossible. No cheaper equivalents were found in the search, but the lack of published pricing, combined with known hidden costs (tier-lock-in via overages, network premiums, and billing-history requirements), suggests you should benchmark against AWS RDS, Google Cloud SQL, and Azure Database for PostgreSQL before committing.
