Both platforms are scored with the same methodology and the same category rubric. Nothing on this page is influenced by advertising.

| Pricing | Not published (vendor pricing page could not be retrieved this session); third parties cite Flex from roughly $8/month and dedicated M10 at roughly $0.08/hour (~$57/month) · free tier: M0 free cluster; third-party sources describe 512MB storage with shared RAM and vCPU. Capterra's provider listing records a free version but no free trial. | Cloud SQL shared-core db-f1-micro $0.0105/hr (us-central1); no SLA coverage for shared-core machine types · free tier: Cloud SQL: $300 in free credits for new customers plus a separate Cloud SQL free trial with restrictions removed on upgrade; AlloyDB: 30-day free trial cluster with up to 1 TB data, an 8-vCPU primary and an 8-vCPU single-node read pool, in addition to the 90-day $300 Google Cloud free trial. |
| Pricing model | Usage-based with tiered cluster sizes (free tier available) | Usage-based |
| Best for | Development teams with variable or document-shaped data who value developer velocity and multi-cloud freedom, and teams that want vector and full-text search in the same managed engine as their operational data. | Teams already standardised on Google Cloud running MySQL or PostgreSQL who want managed HA and PITR without DBAs, and have predictable enough capacity to commit to 1- or 3-year CUDs; for read-heavy PostgreSQL at scale, AlloyDB's shared-storage model and 288-vCPU nodes are the stronger fit. |
| Avoid if | You are on a fixed budget with no FinOps oversight, are new to databases, are fully committed to one hyperscaler whose native service integrates better, or have genuinely relational, heavily transactional workloads better served by Postgres. | You are a solo developer or small project needing a cheap SLA-backed instance, you hold existing SQL Server licences (no BYOL, $0.47/core-hr Enterprise with a four-core minimum), you need a firm forecastable monthly number before signing, you run an EOL major version, or your architecture is egress-heavy to clients outside Google Cloud at $0.19/GiB. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
