| Pricing | 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. | Pro from $25/mo (additional projects from $10/mo) · free tier: $0/mo: unlimited API requests, 50,000 MAU, 500 MB database, shared CPU/500 MB RAM, 5 GB egress, 5 GB cached egress, 1 GB file storage, community support; projects paused after 1 week of inactivity, max 2 active projects, no backups/PITR/branching |
| Pricing model | Usage-based | Subscription with usage-based add-ons |
| Best for | 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. | Small to mid-sized product teams with at least one SQL-comfortable engineer who need a relational database plus auth, storage and realtime from a single open-source vendor and want to ship fast. |
| Avoid if | 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. | You are a non-technical builder, need SOC 2/ISO 27001/SSO/HIPAA at modest spend, require annual invoicing and procurement-friendly terms, want only a plain managed database, or cannot tolerate a billing dispute turning into a service suspension. |

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.
