$6.95/TB/month (= $0.00695/GB); first 10 GB free. Egress is free up to 3× your average monthly stored data, then $0.01/GB — the model can't tie the allowance to storage, so egress is shown as free; add $0.01/GB for anything above 3× what you store. Egress through partner CDNs (Cloudflare, Fastly, bunny.net…) is free. Class D API calls cost $0.004 per 10,000 after 2,500/day (not modelled).

Storage is $0.023/GB for the first 50 TB, then $0.022 (next 450 TB) and $0.021 (over 500 TB). The first 100 GB/month of internet egress is free (aggregated across all AWS services); egress is $0.09/GB for the next 10 TB, then $0.085, $0.07 and $0.05 at higher volumes. Requests (PUT/GET) and other storage classes are not modelled.
FirebaseBlaze (pay as you go)$14/mo95 GB × $0.02 per GB + 100 GB × $0.12 per GBCloud Storage for new (*.firebasestorage.app) buckets needs the Blaze plan; the Spark plan no longer includes it. No-cost usage (5 GB-months stored, 100 GB/month downloaded) applies only to buckets in us-central1, us-west1 or us-east1. Beyond it, Google Cloud Storage prices apply (https://cloud.google.com/storage/pricing) — Standard storage in us-central1 is $0.020/GiB-month and internet egress $0.12/GiB for the first 10 TiB. Operations beyond 5K uploads / 50K downloads per month are not modelled.
SupabasePro$25/mo$25 planThe Pro fee covers the whole Supabase project (database, auth, storage). Egress here is uncached egress; downloads served from Supabase's CDN cache have a separate 250 GB allowance on Pro (5 GB on Free) and cost $0.03/GB beyond it. Free projects pause after a week of inactivity.
Vercel BlobPro$32/mo$20 plan + 100 GB × $0.023 per GB + 200 GB × $0.05 per GBPro rates are for the iad1 (Washington D.C.) region; other regions differ. The $20/month Pro fee is Vercel's platform plan and comes with $20 of usage credit shared across all Vercel resources, which can absorb Blob usage — not modelled. Hobby is free but Blob stops working (for 30 days) once the limits are hit, and its allowance is shared with the project's other Vercel usage. Operations ($0.40/M simple after 10K, $5.00/M advanced after 2K on Hobby), CDN requests and Fast Origin Transfer on cache misses ($0.06/GB) are not modelled. Pro can opt into Flat Rate CDN, whose lowest tier (included with Pro) covers 1M CDN requests and 1 TB of transfer including Blob Data Transfer, but Vercel excludes workloads where file delivery is the main use, so on-demand rates are shown.
Read from each vendor's pricing page (oldest check 2026-10-03). The model is plan fee + usage beyond what's included × the vendor's rate; volume discounts, annual billing, taxes and regional prices are left out — see each tool's notes. Always confirm on the vendor's page before you commit.
