Serverless Postgres Cost Comparison
Compare the same workload shape across Neon Launch, Supabase Pro and PlanetScale Postgres. Scenario A (side project): Neon ≈30 CU-h + 1 GB, Supabase Micro $25, PlanetScale non-HA PS-10 ARM $10. Scenario B (always-on): Neon 1 CU × 730 h + 20 GB, Supabase Micro + 20 GB disk, PlanetScale HA PS-20 ARM $50. Apples differ — Neon sleeps; Supabase and PlanetScale are always-on.

Scenario A (side project / scale-to-zero): Neon Launch ≈30 CU-hours (0.25 CU × ~4 h/day) + 1 GB storage; Supabase Pro 1× Micro within quotas ($25); PlanetScale non-HA PS-10 ARM ($10). Apples: Neon sleeps, Supabase always-on Micro + plan floor, PlanetScale always-on SKU. Scenario B (always-on prod-ish): Neon Launch 1 CU × 730 h ($77.38) + 20 GB storage; Supabase Pro Micro + 20 GB disk (12 GB overage); PlanetScale HA PS-20 ARM ($50). Narrative: Neon = CU-hours × rate + storage (sleep wins); Supabase = org plan floor + always-on compute sizes + quotas; PlanetScale = pick cluster SKU (HA vs single). Don’t pretend Auth/Realtime/branching extras are equal. Soft-link prior packs: serverless-compute, object-storage, CDN bandwidth.

How it works
- Which is cheapest on Scenario A (side project)?
- Neon Launch ≈30 CU-hours + 1 GB ≈ $3.53 (sleeps when idle), PlanetScale non-HA PS-10 ARM = $10, Supabase Pro Micro = $25. Neon wins when the database can scale to zero; Supabase has a $25 plan floor; PlanetScale is an always-on SKU.
- What does Scenario B (always-on) show?
- Neon Launch 1 CU × 730 h = $77.38 + 20 GB storage; Supabase Pro Micro + 20 GB disk (12 GB overage) ≈ $26.50; PlanetScale HA PS-20 ARM = $50. Always-on Neon CU-hours lose the sleep advantage.
- Why aren't the apples identical?
- Neon bills CU-hours and can sleep; Supabase charges an org plan floor plus always-on compute sizes and quotas; PlanetScale is a picked cluster SKU (HA vs single). Auth, Realtime and branching extras are not equalized.
- Should I compare to serverless functions?
- Soft-link the serverless-compute comparison (Workers / Lambda / Vercel Fluid) and the object-storage / CDN packs — storage → CDN → functions → Postgres is a common 出海 SaaS stack funnel, but billable units differ.
- Are rates dated?
- Yes. List prices verified 2026-11-03 Asia/Shanghai (PlanetScale SKU snapshot dated 2026-11-02). Provider pricing pages prevail.
