Aiven for PostgreSQL offers a free trial for evaluation but no permanent free tier. G2 reviewers, particularly students and hobbyists in higher education, reference free-tier access for learning and hobby projects, suggesting limited free plans exist alongside paid tiers. Aiven for PostgreSQL's paid Startup plans begin at $75/month, providing dedicated VMs, real-time backups, 2-day PITR, connection pooling, and VPC peering. Upgrading to Business ($200/month) adds high availability, 14-day PITR, and read replica access. Premium ($300/month) extends PITR to 30 days and adds a third VM cluster for enterprise-grade redundancy. G2 reviewers note the jump between entry and mid tiers is significant.
