Database engines and platform direction
PlanetScale now offers two managed database families: Vitess for MySQL-compatible horizontal scale and PostgreSQL clusters on modern cloud infrastructure. That gives buyers engine choice and a path to high-performance provisioned deployments, including network-attached storage and Metal configurations. Neon is PostgreSQL-only and builds its identity around disaggregated compute and storage, autoscaling, scale to zero, instant branching, and a large fleet of small databases. The comparison is therefore not simply MySQL versus Postgres; it is provisioned performance and multi-engine breadth versus serverless Postgres elasticity.
Teams standardizing on MySQL or Vitess should prefer PlanetScale because Neon cannot satisfy that compatibility requirement. Teams standardizing on PostgreSQL must compare operating models. PlanetScale gives each Postgres branch its own dedicated cluster and bills the compute and storage that power it. Neon branches share storage efficiently and attach computes that can autoscale and suspend when idle. For preview environments, agent-generated apps, and bursty SaaS workloads, Neon's model maps more directly to actual use; for sustained high-throughput databases, PlanetScale's provisioned topology may be easier to benchmark.
Branching and development workflow
Both platforms use database branches, but the economics and implementation differ. In PlanetScale Postgres, a branch is an isolated deployment with its own cluster, intended for development, testing, and backup restoration; each branch's cluster is billed according to its configuration and usage. This produces strong isolation but makes a large number of long-lived branches an explicit infrastructure choice. PlanetScale's established workflow and query insights remain valuable for teams that want controlled database changes and production-like branch environments.
Neon branches are copy-on-write database states that can be created quickly for pull requests, tests, experiments, and per-agent sandboxes. Current plans include multiple branches per project, and additional branches are billed by branch-hour only beyond the included allowance. Short-lived child branches share data with their parent and can be assigned expiration times, while their compute scales to zero when inactive. That makes Neon the better developer workflow for ephemeral environments: a CI job can create, use, and destroy a realistic Postgres branch without funding a continuously provisioned cluster.
Autoscaling, suspension, and connection behavior
Neon separates compute from storage and automatically adjusts compute within configured bounds. On the Free plan, inactive computes suspend after five minutes; paid plans can configure or disable scale to zero. A suspended endpoint reactivates on the next query within hundreds of milliseconds, so idle development databases consume no compute hours. Neon also supports connection pooling, read replicas, and compute sizes from small fractional units to large production instances, allowing a project to mix inexpensive previews with always-on production endpoints.
PlanetScale Postgres clusters are provisioned resources whose size can be changed and whose billing is prorated to the millisecond after a resize. Network-attached storage can scale independently, while Metal packages local NVMe storage with the instance. This is not the same as scaling to zero: each active branch has a cluster configuration and cost floor. PlanetScale is better when steady workloads need predictable CPU, memory, IOPS, and high availability. Neon is better when utilization is uneven or the organization operates dozens to thousands of databases with long idle periods.
Pricing and cost shape
Neon's Free plan currently includes 100 projects, 100 compute-unit hours per month for each project, 0.5 GB of storage per project, autoscaling, branching, and read replicas. The Launch plan is usage based, with a typical intermittent-load example around $15 per month, $0.106 per compute-unit hour, and $0.35 per GB-month. Because compute can scale to zero, a preview or low-traffic project pays mainly while it is active. Larger Scale workloads use different compute rates and governance features, so production budgets still require workload measurement.
PlanetScale Postgres single-node network-attached clusters start at $5 per month, highly available entry configurations start higher, and Metal clusters start at $50 per month. Each branch runs on its own cluster, with compute, storage, backup, egress, and extra replicas contributing to the bill; the first 10 GB of network-attached storage is included with a cluster. PlanetScale can be economical for a small continuously used database, but Neon is more forgiving for fleets and intermittent demand. Cost leadership changes when sustained load makes suspension irrelevant and PlanetScale's performance profile becomes the priority.
Ecosystem, portability, and operational control
Neon is standard PostgreSQL, so teams can use familiar drivers, ORMs, migrations, logical replication, pgvector, and the wider extension ecosystem subject to platform support. The serverless driver and pooling options address high-concurrency web and edge deployments, while conventional connections remain available. Branching and autoscaling are platform features rather than changes to SQL semantics. That lowers migration risk for Postgres applications and makes it straightforward to move workloads between Neon, local Postgres, and another managed provider if necessary.
PlanetScale's Vitess product is MySQL compatible and excels when horizontal sharding or MySQL ecosystem fit is the requirement. Its newer Postgres offering adds a second path with dedicated clusters, network-attached storage, Metal, backups, replicas, private networking, and query tooling. The breadth is attractive to organizations that want one vendor for two engine families. It also means the buyer must specify which PlanetScale architecture is being evaluated. Neon is the clearer default for a Postgres-first application; PlanetScale is the stronger specialist for Vitess/MySQL or provisioned high-performance needs.
Verdict: Neon wins the serverless Postgres evaluation
Choose PlanetScale when MySQL/Vitess compatibility is mandatory, when sustained write throughput and predictable provisioned resources matter more than idle efficiency, or when Metal's local NVMe profile matches a benchmarked production workload. PlanetScale also suits teams that want isolated clusters per branch and are prepared to budget for that isolation. A serious evaluation should benchmark the actual query mix, failover expectations, storage growth, replica requirements, and total branch count rather than comparing headline entry prices.
Neon is the winner for the intended serverless-database buyer. Its free allowance, usage-based compute, automatic scale to zero, copy-on-write branching, and standard PostgreSQL ecosystem reduce both experimentation cost and operational friction. The advantage is strongest for startups, preview environments, AI-generated applications, and multi-tenant platforms with bursty demand. PlanetScale remains a high-quality database platform, but Neon's architecture provides the more complete serverless experience and the safer default when future utilization is uncertain.
