5 Google Cloud SQL for PostgreSQL Alternatives in 2026

Google Cloud SQL for PostgreSQL is a natural fit for Google Cloud apps. But if you are not already deep in Google Cloud, it can be more platform than you need.

Here are five Cloud SQL for PostgreSQL alternatives for 2026.

Quick comparison

1. Sliplane Managed Postgres

Sliplane Managed Postgres is managed PostgreSQL for teams that want boring production Postgres done well.

Sliplane is a German company based in Berlin. Managed Postgres is available in Germany, the US, Finland, and Singapore. Every database includes automated point-in-time recovery, SSL by default, automatic security updates, built-in metrics and logs, free egress, API access, and the first 10 GB of storage.

Pricing starts at 19 EUR/month, excluding tax, for the Starter tier in Germany. That gives you 1 vCPU, 1 GB RAM, and 10 GB included storage. You can resize without downtime, so the normal path is: start small, watch the database, then scale when you actually need it.

The Postgres product is deliberately focused. It is for teams that want the database basics to be excellent: backups, restores, SSL, monitoring, predictable pricing, no egress surprise, zero-downtime resizes, and a short path from "create database" to "ship the app".

Use Sliplane if:

• you want boring production Postgres without running database ops.
• you want PITR, SSL, metrics, logs, and egress included on every tier.
• you want predictable pricing without hyperscaler billing details.
• you already run apps on Sliplane or want app hosting and databases close together.

Skip it if:

• you want Supabase-style auth, storage, realtime, and generated APIs.
• you specifically need serverless branching or scale-to-zero.
• you need a large enterprise database platform with every possible knob.

2. Neon

Neon is serverless Postgres with storage-compute separation. Compute can scale down when idle while storage persists separately.

Neon is genuinely interesting if you want serverless database workflows: scale-to-zero, branching, preview databases, short-lived environments, and development flows where each branch gets its own database. For low-load apps and teams that care about those workflows, it can be a strong fit.

The caution is production fit under real load. If you expect sustained traffic, heavy queries, or a database that should feel boring and always-on, benchmark carefully and read incident history before committing. Neon's usage model also means you need to understand CU-hours, storage, and history retention instead of only looking at the headline plan.

Use Neon if:

• you want branching and preview databases.
• your database can benefit from scale-to-zero.
• you have light or spiky load and like serverless workflows.

Skip it if:

• you expect heavy sustained database load.
• you want fixed monthly pricing.
• you prefer a traditional always-on managed database.

3. Supabase

Supabase is a Postgres-based app backend with auth, storage, realtime, edge functions, APIs, and dashboard tooling, not just a managed Postgres host.

That is the reason to choose it. Supabase is great when you want Postgres together with Auth, Storage, Realtime, Row Level Security workflows, generated APIs, Edge Functions, and a polished dashboard. For a product team that wants those integrations, it can remove a lot of glue work.

The tradeoff is that you are buying a platform. If all you need is boring production Postgres, Supabase can be more product surface than necessary. Billing also includes plans, quotas, usage, compute choices, and add-ons, so it is not as simple as one database tier.

Use Supabase if:

• you want Postgres plus auth, storage, realtime, and APIs.
• Row Level Security and dashboard workflows are central to your app.
• you value the integrated developer experience more than a minimal database product.

Skip it if:

• you only want a boring production database.
• you want the simplest possible Postgres bill.
• you do not want platform-specific features around the database.

4. Crunchy Bridge

Crunchy Bridge is fully managed Postgres from Crunchy Data, a company with deep Postgres credibility.

The pitch is database specialist, not app platform. Crunchy Bridge is interesting when you want expert Postgres support, serious database features, PostGIS/extensions, high availability options, read replicas, private networking, and a provider that thinks primarily in Postgres terms.

Without a strong firsthand product signal, Crunchy Bridge is best treated as a specialist option to evaluate when support quality and Postgres depth are more important than a simple app-deployment workflow.

Use Crunchy Bridge if:

• you want Postgres specialists.
• support quality and database depth matter.
• your team wants a database-first product, not an app platform.

Skip it if:

• you want managed Postgres next to app hosting.
• you are optimizing for the simplest small-team workflow.
• you want a provider headquartered in Germany.

5. IONOS Cloud PostgreSQL

IONOS Cloud PostgreSQL is IONOS Cloud's Database as a Service for PostgreSQL. It has real managed-database features: multi-node high availability, TLS, private LAN support, daily base backups, point-in-time recovery, restores, service monitoring, API access, Terraform, and Ansible integration.

The problem is not the checkbox list. The problem is the experience around it. IONOS feels like an infrastructure cloud first and a modern developer product second. The pricing model is component-based, the console workflow is heavier than most small app teams want, and seeing HDD still show up as a storage option in 2026 tells you a lot about the product posture.

IONOS can make sense when you are forced into IONOS by procurement, vendor policy, or an existing German cloud commitment. If you are choosing freely, it is hard to recommend over smoother managed Postgres options.

Consider IONOS if:

• your company already buys from IONOS and procurement prefers that vendor.
• you need a German infrastructure-cloud supplier.
• your team is comfortable with heavier cloud-console workflows.

Skip it if:

• you are free to choose the best developer experience.
• you want simple managed Postgres for an app team.
• rough UX or support would slow your team down.

Which provider should you choose?

Cloud SQL is a sensible pick if your application is already on Google Cloud. Outside that context, simpler managed Postgres providers can be easier to buy, understand, and operate.

Sliplane is the straightforward choice when you want managed Postgres in Germany without adopting a full hyperscaler operating model.
