Honest read on positioning, ideal customer, and where each one is the wrong call. No vendor sponsorship, no affiliate links — operator-grade signal.

1. Supabase Series C+ · OSS Postgres + bundled stack

The bundled-Postgres default for new SaaS in 2026. Hosted Postgres + Auth + Storage + Realtime + Edge Functions in one console. Open-source core, generous free tier, RLS-first authorization model. Most popular pick for indie devs and AI startups shipping fast.

✓ Strongest atBundled stack (DB + Auth + Storage + Realtime), Postgres RLS, OSS portability, fastest 0→prod for full SaaS, pgvector for AI workloads.
✗ Wrong forPure serverless edge-first apps (Neon/Turso win). Massive horizontal-scale OLTP (PlanetScale's MySQL Vitess wins). Analytical workloads (MotherDuck wins).
Pick Supabase if: you want one console for DB + auth + storage and don't want to wire 5 vendors together.

2. Neon Acquired by Databricks · Serverless Postgres

The serverless Postgres with database branching. Compute scales to zero, branches DB like Git for preview environments, cold-start measured in ms. Pure Postgres (no Supabase-style bundling). Acquired by Databricks in 2025 — enterprise-roadmap accelerated.

✓ Strongest atServerless cold-start (scale-to-zero), DB branching for preview/PR envs, pure Postgres compatibility, Databricks lakehouse roadmap.
✗ Wrong forApps that want bundled auth + storage (Supabase wins). MySQL stacks (PlanetScale). Edge-first reads (Turso).
Pick Neon if: you want serverless Postgres with branch-per-PR and don't need bundled auth/storage.

3. PlanetScale Series C · MySQL Vitess at scale

The horizontal-scale MySQL platform built on Vitess (YouTube's sharding layer). Killed the free hobby tier in 2024, repositioned as serious-production-MySQL. Schema-change deploy workflow (branches → deploy requests) is best-in-class. Now offers Postgres beta.

✓ Strongest atHorizontal MySQL scale (Vitess sharding), zero-downtime schema changes, deploy-request workflow, mature enterprise SLAs.
✗ Wrong forIndie/hobby projects (no free tier). Postgres-required stacks (use Neon/Supabase). Bundled-auth needs.
Pick PlanetScale if: you're MySQL-stack at scale and need bulletproof schema migrations + horizontal sharding.

4. Turso Series A · Edge SQLite (libSQL)

The edge-replicated SQLite (libSQL fork) for read-heavy global apps. Replicas in 30+ regions, sub-10ms reads from anywhere, embedded-mode option for local-first apps. SQLite ergonomics with cloud sync. Strong fit for AI agent state + edge-runtime apps.

✓ Strongest atEdge-replicated reads (sub-10ms global), embedded SQLite for local-first, generous free tier, AI agent state stores, per-tenant DB isolation.
✗ Wrong forHeavy write throughput (SQLite-class limits). Complex JOINs at OLTP scale (Postgres wins). Bundled auth/storage.
Pick Turso if: you're edge-first, read-heavy, or per-tenant-DB and SQLite semantics fit your data model.

5. Xata Pivoted to Postgres platform in 2024

The Postgres + search + branching + AI platform. Pivoted from proprietary store to pure Postgres in 2024. Bundles full-text search, vector search, branching, and a typed TypeScript SDK. Smaller user base than Supabase/Neon but strong DX for TS-first teams.

✓ Strongest atTyped TypeScript SDK, bundled search (full-text + vector), DB branching, file attachments column, schema-as-code workflow.
✗ Wrong forNon-TypeScript stacks (DX advantage shrinks). Teams already on Supabase/Neon (overlap is large).
Pick Xata if: you're TypeScript-first and want typed schemas + bundled search without wiring Algolia/Pinecone separately.

6. MotherDuck Series B · Serverless DuckDB analytics

The serverless DuckDB for analytics workloads under 1TB. Hybrid execution — query splits between local DuckDB and cloud. Not an OLTP database — it's the small-data-warehouse alternative to Snowflake/BigQuery for teams that don't need PB-scale. Cheap, fast, SQL-native.

✓ Strongest atSub-TB analytics (10-100x cheaper than Snowflake at this scale), DuckDB SQL compatibility, hybrid local+cloud execution, no infra to manage.
✗ Wrong forTransactional/OLTP workloads (use Postgres/MySQL). PB-scale warehouse (Snowflake/BigQuery still win). Real-time event ingestion.
Pick MotherDuck if: you have analytics under 1TB and Snowflake feels like overkill (and overcost).

The Calling Matrix · siren-based ranking by who you are.

Most comparison sites refuse to forced-rank because their revenue depends on staying neutral. SideGuy ranks because it doesn't take vendor money. Here's the call by buyer persona.

🚀 If you're a Solo dev / indie hacker shipping first SaaS

Your problem: You're 1 person trying to ship a SaaS in days, not weeks. You need a database in production tonight, plus auth and probably file storage. You don't want to wire 4 vendors together. You want a free tier that won't surprise-bill you when you get on Hacker News.

  1. Supabase — bundled DB + auth + storage = one console, fastest 0→prod for a full SaaS
  2. Neon — if you only need DB (no auth/storage) and want pure Postgres serverless
  3. Turso — if your app is read-heavy and SQLite semantics fit (also generous free tier)
  4. Xata — if you're TypeScript-first and want typed schemas out of the box
  5. PlanetScale — rarely the right pick at this stage — no free tier, MySQL-only friction
If forced to one pick: Supabase — bundled stack means one vendor, one bill, one console. Refactor later if you outgrow it.

🤖 If you're a AI startup at 5-30 person co (multi-region, edge-runtime, vector)

Your problem: You're building AI-native product. You need vector search, multi-region reads (your users are global), and your runtime is probably Vercel/Cloudflare edge. You also need DB branching for preview deploys because your team ships 20+ PRs/day.

  1. Neon — branch-per-PR is killer for AI iteration, pgvector is mature, scale-to-zero matches edge cost model
  2. Supabase — pgvector + bundled auth/storage if you want one vendor — read replicas now exist
  3. Turso — if your reads are dominantly edge-global and SQLite semantics work for your data
  4. Xata — bundled vector + full-text search + branching, TS SDK if you're Next.js-stack
  5. PlanetScale — MySQL is awkward for vector workloads — only if you're already MySQL-locked
If forced to one pick: Neon — branch-per-PR + serverless Postgres + pgvector is the tightest fit for AI startup velocity.

📈 If you're a Scale-up at 100-500 person co (cost-conscious, branching for preview envs)

Your problem: You have 50+ engineers shipping daily. Your AWS RDS bill is creeping up, schema migrations cause weekend incidents, and your preview environments share a staging DB so engineers step on each other. You need horizontal scale OR branching, ideally both, without blowing up DevOps.

  1. PlanetScale — deploy-requests + zero-downtime schema changes is the gold standard for this scale, Vitess sharding is battle-tested
  2. Neon — branch-per-engineer is the killer feature — preview envs stop colliding, Postgres-compatible
  3. Supabase — self-hostable if compliance demands it, branching is now in beta
  4. Xata — branching + typed schemas reduce migration foot-guns, smaller scale ceiling than Neon/PlanetScale
  5. Turso — per-tenant DB is interesting if you're multi-tenant SaaS, otherwise wrong shape
If forced to one pick: PlanetScale if MySQL · Neon if Postgres — both solve the migrations + branching pain better than RDS.

💰 If you're a Cost-conscious CTO escaping legacy MySQL/Postgres-on-RDS bills

Your problem: Your RDS + Aurora bill is $X0K/month and growing. Half your DBs are over-provisioned because your traffic is bursty. You also pay for IOPS you don't use. Your team can absorb a migration if savings justify it and the new stack doesn't require a DBA.

  1. Neon — scale-to-zero kills idle-DB cost, pure Postgres = lift-and-shift, biggest TCO win for bursty workloads
  2. PlanetScale — if you're MySQL — predictable per-row pricing beats RDS IOPS for high-throughput shops
  3. Supabase — if you can also collapse Auth0 / S3 / Pusher costs into the same vendor
  4. MotherDuck — for analytics/reporting DB only — 10-100x cheaper than Snowflake under 1TB
  5. Turso — for read-heavy edge cases where you can shed Postgres and adopt SQLite
If forced to one pick: Neon for Postgres workloads · MotherDuck for the analytics half — both unbundle RDS bills cleanly.

FAQ · most asked questions.

Supabase vs Neon — which one should I pick in 2026?

Supabase if you also need bundled auth, storage, and realtime in the same console — fastest 0→prod for a full SaaS. Neon if you only need the database and want pure serverless Postgres with branch-per-PR for preview envs. Both are Postgres-compatible, so migrations between them are realistic. Neon wins on serverless cost (scale-to-zero) and DX for engineering teams shipping multiple PRs/day. Supabase wins on solo-dev velocity and reduced vendor count.

Is PlanetScale still worth it after killing the free tier?

Yes, but only if you're already MySQL-stack at scale or planning to be. The free-tier kill in 2024 repositioned PlanetScale as serious-production-MySQL — they're not chasing hobby projects. The deploy-request workflow + Vitess horizontal sharding are still best-in-class for MySQL at scale. If you're not MySQL or not at scale, Supabase / Neon / Turso are better fits. PlanetScale's Postgres beta is too new (as of May 2026) to bet on yet.

When does Turso's edge SQLite beat Postgres?

Three cases: (1) read-heavy global app where sub-10ms reads from any region matter more than complex JOINs, (2) per-tenant DB architecture (one SQLite per customer is cheap and isolated), (3) AI agent state stores or local-first apps where embedded mode + cloud sync is the right shape. For traditional OLTP SaaS with heavy writes and complex relationships, Postgres (Supabase/Neon) still wins.

What does MotherDuck do that Snowflake doesn't?

MotherDuck is purpose-built for the under-1TB analytics workload that Snowflake/BigQuery overcharge for. Hybrid execution splits queries between your local DuckDB and the cloud — fast and cheap. If your analytics workload is small-to-mid (most companies under 500 employees), MotherDuck is 10-100x cheaper. If you're at PB scale or need Snowflake's mature governance/sharing, stay on Snowflake. They're not really competing for the same buyer.

Can I self-host any of these?

Supabase (yes — fully open-source, self-hostable on your own infra). The others are managed-cloud only: Neon (closed-source control plane, OSS Postgres underneath), PlanetScale (closed-source on top of OSS Vitess), Turso (closed-source cloud, but libSQL the SQLite fork is OSS and you can run it embedded), Xata (closed-source, runs on managed Postgres now), MotherDuck (closed-source, DuckDB itself is OSS and self-hostable but without MotherDuck's hybrid features). If self-host is a hard requirement, Supabase is the only complete answer in this list.
