Pricing Comparison

MongoDB Atlas

Free (M0)

Free

Users: N/A

Storage: 512MB

Limits: 512MB limit, no VPC peering, no dedicated support, shared cluster performance

No backups, limited connections, shared resources affect performance

Flex Tier

$8/mo

Users: N/A

Storage: 5GB

Limits: Variable workloads only, not for consistent high-throughput

Storage charges extra, data transfer adds up, backup costs separate

Dedicated M10

Popular

$57/mo

Users: N/A

Storage: 10GB

Limits: Entry production tier, may need M30+ for significant workloads

Data transfer $0.02-0.15/GB, backup storage extra, Atlas Search indexing costs

Dedicated M30

$390/mo

Users: N/A

Storage: 40GB

Limits: ~$0.54/hour, still entry-level for larger workloads

All data transfer and backup costs apply, Atlas features may cost extra

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.
