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. Estimates only; provider pages prevail.

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.
