Issue #6 - Database Tools: Supabase vs Neon vs Turso vs PlanetScale (2026)
The serverless database landscape has fundamentally shifted in 2026. PlanetScale killed its free tier. Neon was acquired by Databricks for $1B. Turso doubled its free tier limits. Supabase crossed 2M projects. If you're choosing a database today, the decision matrix looks nothing like it did 18 months ago.
The Core Distinction: Database vs Platform vs Edge
Before comparing features, understand what each product actually is. They are not three flavors of the same thing.
| Product | Category | Engine | Philosophy |
|---|---|---|---|
| Supabase | Backend-as-a-Service (BaaS) | PostgreSQL 15 | "Firebase alternative" — bundled Auth, Storage, Realtime, Edge Functions, pgvector |
| Neon | Serverless PostgreSQL | PostgreSQL 16+ | "Pure Postgres" — branching-first, scale-to-zero, no bundled services |
| Turso | Edge-native SQLite | libSQL (SQLite fork) | "Data at the edge" — embedded replicas, per-user databases, sub-ms reads |
| PlanetScale | Vitess/MySQL at scale | MySQL (Vitess) | "Horizontal sharding without ops" — non-blocking schema changes, YouTube-grade scale |
Free Tier Comparison (2026)
For founders validating ideas, the free tier determines how long the project survives before the first credit card charge.
| Feature | Supabase Free | Neon Free | Turso Free | PlanetScale Free |
|---|---|---|---|---|
| Engine | Postgres 15 | Postgres 16+ | libSQL (SQLite fork) | — |
| Storage | 500 MB | 512 MB | 9 GB total | None (removed Apr 2024) |
| Compute | Shared, auto-pause after 7 days idle | 0.25 vCPU, scale-to-zero | Shared | — |
| Databases/Projects | 2 active | Up to 100 projects | Up to 100 databases | — |
| Bundled Services | Auth, Storage, Edge Functions, Realtime | None | None | — |
| Row Reads/Month | Unlimited (API) | Unlimited | 500M | — |
| Inactivity Behavior | Pauses after 7 days (app goes down) | Stays alive (scales to zero) | Stays alive | — |
Critical Free Tier Insights
Neon's free tier is now the most developer-friendly for side projects. Scale-to-zero means your project stays reachable even after weeks of inactivity — no "wake up" delay for users. The 100-project allowance lets you spin up a new database per experiment without cleanup.
Supabase's free tier includes $20-50/month worth of adjacent services (Auth, Storage, Edge Functions, Realtime) that you'd need to stitch together separately on Neon. But the 7-day auto-pause kills side projects that go quiet.
Turso's 9 GB storage and 100 databases is genuinely generous — enough for per-tenant isolation in a multi-tenant SaaS on the free tier. The 500M row reads/month covers substantial read-heavy workloads.
PlanetScale has no free tier. Budget at least $5/month per database (single-node PS-5) or $39/month for the Scaler Pro tier with HA.
Paid Tier Pricing (2026)
| Plan | Supabase | Neon | Turso | PlanetScale |
|---|---|---|---|---|

Real-World Cost Scenarios (Verified Sept 2026)
| Workload | Supabase Pro | Neon Launch | PlanetScale (HA) | Turso Scaler |
|---|---|---|---|---|
| 1 GB DB, 20 GB storage, 300 GB egress | ~$31/mo | ~$26/mo | ~$43/mo | ~$25/mo |
| Idle side project | $0 (pauses) | $0 (scale-to-zero) | $5+/mo | $0 |
| 400K MAU app | ~$1,213/mo | ~$278/mo | ~$200+/mo | Varies by read/write ratio |
Neon's acquisition by Databricks (2025) triggered 15-25% compute price drops and 80% storage price drops. Over 80% of databases on Neon are now created by AI agents — the platform is optimizing for agentic workloads.
Decision Framework: Pick by the Brief
→ Solo Founder, First MVP, One Dashboard
Supabase. Auth + DB + Storage + Realtime + Edge Functions in one place. Fastest path from idea to launched product. The $25/mo Pro plan covers most early SaaS apps with the $10 compute credit.
→ Team with Existing Auth/Storage, Want Just Postgres
Neon. Branching per preview deploy is the killer feature for teams shipping multiple PRs/week with DB changes. Pair with Clerk/Auth0 for auth. Databricks acquisition ensures long-term Postgres investment.
→ Read-Heavy App, Global Users, Edge Deployment
Turso. SQLite at the edge with 1B free reads is a different architectural shape. Right for content directories, e-commerce catalogs, programmatic SEO sites where read latency dominates UX.
→ Multi-Tenant SaaS Without RLS Risk
Turso (per-user databases). Each customer gets their own isolated database with its own API key. No row-level policies to debug, no cross-tenant leak risk from a misconfigured WHERE clause. Free tier supports 100 databases.
→ Preview Environments, PR-Based Dev Workflow
Neon (branching). Every Vercel preview deploy gets its own ephemeral Postgres branch with full production data. No fixtures, no seed scripts. Transforms CI/CD for database-touching changes.
→ AI/Vector Search Built Into Database Layer
Supabase (pgvector). Full Postgres + pgvector + hybrid search + HNSW indexes in one platform. HIPAA add-on at $350/mo on Team plan for healthcare AI apps.
→ MySQL Workload at Scale with Sharding Requirements
PlanetScale. Vitess sharding + branching combo is unique. If you're already on MySQL at scale and want the platform without running it yourself, PlanetScale earns the price.
→ Agentic Infrastructure (One DB Per Agent/Session/User)
Turso. The per-user database architecture is architecturally simpler than RLS or branching for isolation. One database per agent, per session, per user — each with its own token.
Practical Hybrid Worth Considering
Turso for the main database (cheap, fast, isolated) + Supabase for Auth only.
Multiple developers have landed on this combination: getting the performance and isolation benefits of Turso with the convenience of Supabase Auth without buying into the full Supabase platform. Supabase Auth can be used standalone against any Postgres-compatible backend.
The Verdict
For most founders building their first SaaS MVP in 2026, Supabase remains the fastest path from idea to launched product. Start there.
If the project outgrows Supabase's pricing model (the $25→$599 cliff is real) or RLS complexity becomes a liability, Neon and Turso are both strong migration targets with clear use cases:
- Migrate to Neon when you want Postgres purity, branching workflows, and scale-to-zero economics
- Migrate to Turso when edge latency matters more than SQL completeness, or you need per-tenant isolation without RLS
The database pick is rarely the bottleneck. The bottleneck is whether the team can ship in whichever database you pick. Pick by primitive-fit, not by feature checklist.
Key Takeaways
- Neon wins on free tier + branching DX for teams with existing auth/storage
- Supabase wins on bundled services + fastest MVP path for solo founders
- Turso wins on edge latency + per-tenant isolation without RLS
- PlanetScale wins on horizontal sharding + non-blocking schema changes for MySQL-at-scale teams
⚡ Quick Hits
1. Neon's AI Agent Adoption Signal

🛠 Build in Public: Database Decision Log
This newsletter issue was researched using web search across 12+ sources (DevTools Academy, StackFYI, Gautam Khorana, Build MVP Fast, Bytebase, 13Labs, vendor pricing pages). All pricing verified against live vendor pages as of October 2026.
My current stack: Supabase (primary) for HostList (91K pages), WordPress Stack Advisor, and client work. Neon for side projects needing branching. Evaluating Turso for a new edge-deployed content directory.
💡 Tip of the Week
Use Neon's GitHub Action for instant preview databases. Add this to .github/workflows/preview.yml:
- uses: neondatabase/create-branch-action@v4
with:
project_id: ${{ secrets.NEON_PROJECT_ID }}
branch_name: preview/pr-${{ github.event.number }}
parent_branch: main
Every PR gets a real database branch with production data in seconds. Merge = auto-cleanup. Zero config after initial setup.
