Pricing Comparison

CockroachDB

Enterprise Free

Free

Users: N/A

Storage: Unlimited (self-hosted)

Limits: Revenue threshold ($10M), community support only, requires self-hosting expertise

Infrastructure costs (servers, storage, networking), operational overhead

Basic (Cloud)

Popular

$0/mo

Users: N/A

Storage: 10GB free

Limits: No SLA, basic support, limited cluster customization

Compute: ~$0.20/vCPU-hour. Storage: tiered by region. Data transfer: separate charges

Standard (Cloud)

$0/mo

Users: N/A

Storage: Pay per GB

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

All components unbundled: compute, storage, backups, CDC, data transfer billed separately

Advanced (Cloud)

$0/mo

Users: N/A

Storage: Custom

Limits: Requires sales engagement, custom contracts

Enterprise pricing negotiated per customer, significantly higher than Standard

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
