Limits: Daily quotas reset, no outbound networking, limited to Google services only

No Cloud Functions, no extensions, no phone auth beyond limits

Blaze (Pay as you go)

Popular

$0/mo

Users: Unlimited

Storage: Pay per GB

Limits: Requires credit card, costs can spike without budget alerts configured

Firestore: $0.18/100K reads, $0.18/100K writes, $0.026/GB-day storage. Egress: ~$0.15/GB. SMS: $0.01-0.06+/message. Functions: $0.40/million invocations

Cloud Functions

$0.4/mo

Users: N/A

Storage: N/A

Limits: Only on Blaze plan, cold starts, 9-minute timeout (2nd gen), memory limits

Compute time charges separately, cold starts affect performance, egress costs apply

Firestore

$0.18/mo

Users: N/A

Storage: $0.18/GB-month

Limits: Query limitations (no OR, 10 whereIn limit), no native full-text search

Network egress extra, index costs, real-time listeners count as reads

Upstash

Free

Users: N/A

Storage: 256MB

Limits: Commands limited, no RBAC, no advanced monitoring, rate limited when exceeded

No SLA, no Prod Pack features, limited to single region

Pay-as-you-go

Popular

$0.2/mo

Users: N/A

Storage: Up to 100GB

Limits: Budget cap causes rate limiting, no included SLA (requires Prod Pack)

Costs scale linearly - high traffic can get expensive quickly

Fixed (Pro)

$280/mo

Users: N/A

Storage: 10GB

Limits: Throughput limits may not suit high-traffic apps, Prod Pack separate

Limited requests/second (16K for 100GB). Bandwidth overage at $0.03/GB

Prod Pack (Add-on)

$100/mo

Users: N/A

Storage: N/A

Limits: Not available on Free tier, required for production-grade features

Per-database pricing, adds to base plan cost
