The database landscape in April 2026: 25 services across five categories — managed PostgreSQL, serverless/edge, document/NoSQL, cloud provider, and specialized (vector, graph, time-series, cache). The market is volatile: PlanetScale killed its free tier (April 2024), Supabase tightened pause policies, Neon pivoted to usage-based pricing post-Databricks acquisition, and Aurora PostgreSQL joined the AWS free tier.
Key trends: PostgreSQL has won the developer database war — Supabase, Neon, and Aurora all offer PostgreSQL-compatible free tiers. Edge/serverless databases (Turso, D1) are the fastest-growing category. Vector databases (Weaviate, Zilliz) are essential for AI applications but most only offer limited free tiers. The biggest shift: managed databases are converging on usage-based pricing, making costs harder to predict but scaling more efficient.
This guide covers: pricing tables, category breakdowns, storage and connection analysis, cost comparison for solo developers and teams, hidden costs, and best-for-use-case recommendations — compiled by hand from vendor pricing pages.

Fully managed PostgreSQL services with serverless scaling, branching, and modern DX. The default choice for most applications in 2026.
500 MB Postgres database, 50K monthly active users (Auth), 1 GB file storage, 5 GB bandwidth, 500K edge function invocations, 200 concurrent realtime connections, 2 free projects. Includes Auth, Storage, Realtime, and Edge Functions. Full PostgREST API, pgvector for embeddings, branching on paid plans.
1 GB storage and 100 CU-hours per project, autoscaling up to 2 CU, scale to zero after 5 minutes, up to 100 projects with 10 branches each, auth up to 60k MAU, 5 GB object storage per project. Paid plans are usage-based with no monthly minimum. Branching and connection pooling on all plans.
CockroachDB closed its free Basic plan to new deployments on 2026-09-15; new Cloud organizations get a 30-day free trial with $400 in credit. Clusters created before that date stay on their plans during their current term. PostgreSQL-compatible wire protocol, automatic sharding and replication.
Aurora PostgreSQL serverless on the Free plan: up to 4 ACUs and 1 GiB per cluster, paid from the credits, for as long as the Free plan lasts. Upgrading to the Paid plan lifts the limits, and usage past the credits is billed.
1 GB storage, unlimited tenants, built-in tenant isolation for SaaS applications. PostgreSQL-compatible with virtual tenant databases — each tenant gets logical isolation without separate instances. AI-native embeddings and vector search included.
Databases designed for serverless and edge computing. No connection management, scale to zero, and global distribution.
5 GB total storage, 100 databases, 500 million row reads/month, 10 million row writes/month. Built on libSQL (SQLite fork). Embedded replicas for zero-latency reads at the edge. Edge replicas closed to new users in January 2025. No cold starts — SQLite is always fast. On 2026-10-02 Turso announced that Supabase is acquiring it. Turso says the service keeps running.
5 GB storage, 5 million rows read/day, 100,000 rows written/day. SQLite-based database running on Cloudflare's edge network. Works best with Workers. Automatic replication across Cloudflare's network. Point-in-time recovery: 7 days free, 30 days paid.
Redis: 256 MB, 500K commands/month, 1 database. QStash: 1,000 messages/day, 3 retries. Kafka: removed from free tier. REST-based Redis — works in serverless/edge environments where TCP connections are unavailable. Global replication on paid plans.
512 MB database + file storage, 2 free projects, automatic real-time sync, built-in auth, serverless functions, cron jobs, file storage. TypeScript-first with end-to-end type safety. Automatic caching and reactivity — queries re-run when data changes.
Free tier: none. PlanetScale's offer is recorded as Retired. Our own pricing change record, on 2024-04-08, says: PlanetScale retired its free Hobby plan on 2024-04-08, after stopping new Hobby databases on 2024-03-06. Hobby databases that were not upgraded were put to sleep with their data kept. The cheapest plan became Scaler Pro at $39 a month with 10 GB of storage. Source ↗ Read what we recorded →
Retires December 1, 2026. 1,000 cached queries/day, global edge caching, connection pooling for serverless. Not a database — sits in front of your existing database to provide connection pooling (essential for serverless) and edge caching. Works with any Prisma-supported database.
Document-oriented databases for flexible schemas. Best for rapid prototyping, mobile apps, and content management.
512 MB storage, shared M0 cluster, 500 connections, 100 operations/second max. Includes Atlas Search (full-text), Charts (visualization), App Services (serverless functions), and Triggers. Available on AWS, GCP, and Azure. MongoDB drivers for every major language. Free clusters pause after 30 days with zero connections.

Free tier cluster with shared resources. Couchbase Capella is a managed Couchbase service with SQL++ query language, full-text search, key-value access, and mobile sync (via Couchbase Lite). Multi-model: document, key-value, and search in one platform. Turns off after 72 hours idle (data kept); deleted after 30 days idle.
1 GiB storage on free tier. Multi-model database — document, graph, and relational in one. SurrealQL query language with SQL-like syntax. Real-time subscriptions, authentication, and permissions built in. Newer entrant but growing rapidly.
Database services from major cloud platforms. Best when you are already invested in that ecosystem.
25 GB storage, 25 Write Capacity Units, 25 Read Capacity Units (Always Free). Enough for about 200M requests/month on provisioned capacity. A Free-plan AWS account closes after 6 months unless upgraded. Global tables, streams, and point-in-time recovery available. Fully managed NoSQL with single-digit millisecond latency at any scale.
10 GiB storage, 1 TiB queries/month (Always Free). Serverless data warehouse — no infrastructure management. Standard SQL, ML models via BigQuery ML, real-time analytics via streaming inserts. Integrates with all GCP services and most BI tools.
1 GB storage, 100,000 reads/day, 1,000 writes/day on Workers free plan. Eventually consistent global key-value store optimized for read-heavy workloads. Distributed across Cloudflare's 300+ data centers. Best for configuration, feature flags, and caching.

The sticker price rarely tells the full story. Here are database costs that catch teams off guard.
Traditional databases charge per-connection. MongoDB Atlas free tier: 500 connections. Redis Cloud: 30 connections. In serverless environments, each function invocation opens a connection — without pooling, you will exhaust limits instantly. Supabase and Neon include built-in connection pooling; others require PgBouncer or similar.
Supabase pauses free projects after 1 week of inactivity. Neon scales to zero (fast wake-up but not instant). This means free-tier databases are unsuitable for always-on production use. If uptime matters, budget for a paid tier or choose a service without pausing (CockroachDB, DynamoDB).
Firestore charges per document read — loading a list of 100 items costs 100 reads. DynamoDB charges per Request Unit (RU) where complex queries consume more. CockroachDB charges per Request Unit where pricing depends on query complexity. These models reward efficient queries but punish exploration during development.
Cloud-provider databases (Aurora, DynamoDB, BigQuery) charge standard cloud egress rates. Supabase shares 5 GB egress across all services (database + storage + functions). High-traffic applications can hit egress limits before storage limits. D1 charges no egress and nothing extra for read replicas; Turso closed edge replicas to new users in January 2025.
Migrating from Firestore, DynamoDB, or Convex requires rewriting queries and data access layers. PostgreSQL-compatible databases (Supabase, Neon, CockroachDB) minimize this risk — pg_dump works across all of them. CockroachDB's pg_dump exports schema only. PlanetScale users learned this lesson the hard way when the free tier was removed with 30 days notice.
Database pricing is the most volatile category in developer tools. See full change timeline for all tracked changes.
