Aiven for PostgreSQL vs Firebird

Aiven for PostgreSQL is a managed, hosted relational database service built on open-source PostgreSQL. It automates setup, maintenance, patching, and scaling, and includes automatic failover and point-in-time recovery. The cloud service can run across providers including AWS, Google Cloud, and Azure. Aiven lists more than 50 PostgreSQL extensions, including PostGIS, pgvector, TimescaleDB, and pg_cron, and describes uses in vector search and AI applications. It can integrate with Aiven for Grafana and send metrics to external endpoints such as Datadog. The free tier has a single node, 1 CPU, 1 GB RAM, and 1 GB storage; it has no integrations or connection pooling and a max_connections limit of 20. That tier is excluded from the advertised 99.99% uptime SLA and receives no support services. The Free plan is free; Developer is $5 a month, Startup starts at $75 a month, and Business starts at $180 a month. Paid services include Basic support.

Firebird is a free, open-source relational database management system with ANSI SQL features. It runs on Linux, macOS, and Windows, and supports self-hosted deployment. Its multi-generation architecture generally allows readers to access data without blocking writers. SQL features include stored procedures, triggers, common table expressions, cross-database queries, and flexible transaction management. A Trace API and monitoring tables support real-time monitoring, SQL debugging, and auditing. Security controls include users and roles, GRANT and REVOKE permissions, and a database owner concept; Windows Trusted Authentication can integrate with Windows domain or Active Directory security. Deployment choices include embedded, SuperServer, SuperClassic, and Classic architectures. Backup options include online backups and dumps, as well as incremental backup with partly supported point-in-time recovery. Drivers include Java JDBC,.NET, Python, ODBC, PHP, Delphi, and C++ Builder. Free community support is available through mailing lists, alongside commercial and special support. Firebird lists versions 5.0.4, 4.0.7, and 3.0.14 as latest in their series; versions 2.5 and earlier are discontinued and no longer maintained. The enterprise subscription is €199 a month, billed from €199/month/1 servers.
