Heroku vs Aiven for PostgreSQL Comparison: Everything You Need to Know Before Choosing

Aiven for PostgreSQL is a fully managed relational database service from Aiven that runs the open-source PostgreSQL engine on the major public clouds. PostgreSQL is widely adopted for transactional applications, analytics and geospatial workloads, yet operating it reliably requires attention to backups, replication, failover, patching, performance tuning and security. Aiven removes this operational burden by provisioning and maintaining databases on the customer’s behalf, with automated maintenance and high availability options, so that developers can concentrate on application logic. Its core approach is to offer standard, unmodified PostgreSQL with no proprietary lock-in, along with a consistent management experience regardless of the underlying cloud. This lets organisations adopt multicloud or hybrid strategies and move workloads between providers or regions without redesigning their data layer, and it supports bring-your-own-cloud arrangements for stricter governance. This helps smaller teams run production-grade databases without dedicated database administrators. The service is available on AWS, Google Cloud, Microsoft Azure, DigitalOcean and UpCloud, in numerous regions. Features include automatic daily backups with point-in-time recovery, read replicas, standby nodes for automatic failover, connection pooling through PgBouncer, and support for many extensions such as PostGIS, TimescaleDB and pgvector for AI embeddings. Query statistics and performance insights help teams optimise workloads, while logs and metrics can be sent to observability platforms. Security provisions include encryption in transit and at rest, virtual private cloud peering, private link connectivity, role-based access and compliance with standards such as ISO 27001, SOC 2, GDPR and HIPAA on appropriate plans. Management is available through a web console, CLI, REST API and a Terraform provider, and the database integrates with other Aiven services such as Kafka and OpenSearch. Customers include start-ups, SaaS companies and enterprises across many industries. Pricing starts from around USD 19 with a free trial; there is no permanently free version indicated in this listing.
