Best for: Free
PostgreSQL is free and open-source. Your actual costs are hosting: self-managed on EC2 is $20-200/month depending on instance; managed services like Supabase start at $25/month, AWS RDS from $15/month, and Neon serverless from $0. No licensing cost, ever.
Free. Deploy on any infrastructure. Massive ecosystem, 35+ years of stability, JSON support, and a plugin for virtually everything. There is no reason not to start here for relational data.
Free tier vs. $510/mo average
The default right answer for relational databases. If you're paying licensing fees for Oracle or SQL Server, PostgreSQL should be your migration target. The only real cost is engineering time for migration.
