Pricing Comparison

Firebase

Spark (Free)

Free

Users: Unlimited Auth users

Storage: 1GB Firestore, 5GB Cloud Storage

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

Redis Cloud

Free (Trial)

Free

Users: N/A

Storage: 30MB

Limits: No HA, no backups, no support, expires after trial period

Very limited - only for testing, not production viable

Essentials

Popular

$5/mo

Users: N/A

Storage: 250MB+

Limits: No 99.999% SLA, limited data structures, single region

Higher tiers scale: 1GB ~$18/mo, 5GB ~$85/mo. Limited to shared infrastructure.

Pro

$0.88/mo

Users: N/A

Storage: Custom

Limits: Usage-based can be unpredictable, requires cost monitoring

Hourly billing adds up: ~$640/month minimum. Memory scaling increases costs significantly.

Enterprise

$0/mo

Users: N/A

Storage: Custom

Limits: Requires sales engagement, minimum commitment likely

Negotiated pricing varies widely. Contract commitment typically required.
