PlanetScale vs Turso vs Neon: Edge DB 2026
PlanetScale vs Turso vs Neon: Edge Database 2026
TL;DR
PlanetScale wins for MySQL-compatible teams that need horizontal sharding at scale — its Vitess-backed architecture handles the most demanding write workloads, and its non-blocking schema changes are a genuine superpower for teams that can't take downtime. Turso wins for true edge deployments — its libSQL (SQLite fork) approach replicates databases to 35+ edge PoPs, enabling single-digit millisecond reads from anywhere globally. Neon wins for serverless PostgreSQL — branching, scale-to-zero, and the best Postgres compatibility make it the default choice for most new projects. Note: PlanetScale discontinued its free tier in early 2024, which changed the competitive landscape significantly.
Key Takeaways
- PlanetScale pricing: Scaler Pro from $39/month (no free tier as of 2024)
- Turso pricing: Free tier (500 databases, 9GB storage), Starter at $29/month
- Neon pricing: Free tier (0.5GB storage, scale-to-zero), Launch at $19/month
- Database type: PlanetScale = MySQL (Vitess); Turso = SQLite (libSQL); Neon = PostgreSQL
- Best edge reads: Turso — replicas at 35+ Cloudflare PoPs
- Best PostgreSQL: Neon — full Postgres compatibility, branching, extensions

PlanetScale's free tier removal in March 2024 was a significant inflection point. Teams that had relied on it for side projects and staging environments migrated to Neon, Turso, or Supabase. Neon's free tier (with compute scale-to-zero) is now the most common landing spot for developers who previously used PlanetScale's free plan.
Database Architecture
PlanetScale is MySQL + Vitess. Vitess is the same technology that powers YouTube and Google's internal MySQL deployments — it adds horizontal sharding, connection pooling (1,000+ connections multiplexed to a handful of MySQL connections), and online schema changes. The non-blocking schema change workflow is PlanetScale's defining feature: you deploy schema changes through a deploy request (similar to a PR), and Vitess applies them without locking the table, regardless of row count.
Turso is built on libSQL, an open-source fork of SQLite. The core innovation: libSQL databases can be replicated to edge locations (Turso's network runs on Cloudflare Workers), meaning a database that lives "close to your user" rather than in a single region. Each database has a primary (for writes) and embedded read replicas at edge PoPs. The SQLite API means any application that works with SQLite works with Turso — a massive compatibility surface, especially for mobile and embedded use cases.
Neon is serverless PostgreSQL. The storage layer is separated from the compute layer — compute can scale to zero when idle and spin back up in ~100ms. Neon's storage is backed by S3-compatible object storage with a WAL-based replication layer that enables instant branching: you can branch a 100GB production database in milliseconds (it's a copy-on-write pointer, not a full copy). Full PostgreSQL compatibility means every extension, ORM, and client library just works.
Branching
All three platforms offer database branching, but the models and use cases differ.
PlanetScale's branching was the original inspiration for this category. You branch your database schema (not necessarily data), make changes, and merge via a deploy request that applies the migration non-destructively. The workflow mirrors Git — main branch is production, feature branches are for schema changes. Data branching (copying production data to a branch) is available on higher-tier plans.
Turso's branching creates a full database copy from a parent database. Branches are independent databases that can be used for development, testing, or staging environments. Turso's free tier includes 500 databases, making it easy to create per-PR branches for testing.
Neon's branching is the most powerful for development workflows. Branches are instantaneous (copy-on-write) and include both schema and data — a branch of production has production data available for testing in seconds. This is transformative for teams that need to test migrations against real data volumes. Neon's GitHub Actions integration automatically creates a branch per PR and tears it down after merge.
Edge and Latency
Turso is the clear leader for edge-native deployments. Its read replicas run at 35+ Cloudflare Workers edge locations globally. A user in Tokyo reads from a Tokyo replica; a user in London reads from a London replica. Writes always go to the primary (a single region), but reads are served from the nearest edge node. For read-heavy applications where users are globally distributed, Turso's p50 read latency can be 5–15ms — vs. 50–200ms for a single-region database.
Neon recently added read replicas in multiple regions, but it's not a true edge database — replicas are in specific AWS regions (us-east-1, eu-west-1, ap-southeast-1), not at CDN edge nodes. For most applications, multi-region Neon provides sufficient latency coverage.
PlanetScale also uses a single primary per database with read replicas in additional regions. Its edge story is less compelling than Turso's but sufficient for applications with regional traffic patterns (e.g., a US-primary app that needs low latency for EU users).
Ecosystem and Compatibility
PlanetScale's MySQL compatibility means your existing MySQL ORM (Sequelize, Prisma, Drizzle) works without changes. Vitess does impose some MySQL compatibility restrictions (no foreign keys natively, limited support for certain DDL operations), which can require ORM configuration changes.
Turso's libSQL is compatible with the SQLite API. SQLite is the world's most deployed database, so the compatibility surface is enormous — but most web backend frameworks are designed around MySQL or PostgreSQL, not SQLite. Prisma added libSQL support in 2023; Drizzle has native Turso support. For new projects, the ecosystem is sufficient; for existing MySQL/Postgres apps, migration requires more work.
Neon's PostgreSQL has the broadest compatibility of the three. Every Postgres client, ORM (Prisma, Drizzle, Sequelize, SQLAlchemy, ActiveRecord), extension (pgvector, PostGIS, pg_cron), and framework integration just works. The serverless driver (@neondatabase/serverless) uses HTTP instead of long-lived TCP connections, making it safe for serverless and edge environments where long-lived connections are problematic.
When to Use Which
Choose PlanetScale if:
- You're on MySQL and your team has existing MySQL expertise and tooling
- You need horizontal sharding for extremely high write throughput (millions of writes/hour)
- Non-blocking schema changes are essential — you can't tolerate table locks on a 500M-row table
- You're building at a scale where Neon or Turso's single-region write path would be a bottleneck
Choose Turso if:
- Your application reads outnumber writes dramatically and users are globally distributed
- You're building with a JavaScript/TypeScript edge runtime (Cloudflare Workers, Vercel Edge)
- You want per-user databases (Turso supports 500 free databases — enough for per-tenant isolation)
- Your read latency requirements are strict (<20ms globally)
Choose Neon if:
- You want serverless PostgreSQL with the best branching workflow for development
- You're building a new project and want full Postgres compatibility without operational overhead
- Cost matters — Neon's free tier is the most generous and the $19/month Launch plan covers most starter apps
- You're using pgvector for AI embeddings, PostGIS for geospatial data, or any Postgres extension
