Pricing Comparison

Elasticsearch

Self-Managed (Free)

Free

Users: N/A

Storage: Unlimited (your infrastructure)

Limits: No commercial support, security features limited, requires in-house expertise

Infrastructure costs (memory-heavy), operational overhead, DevOps expertise required

Elastic Cloud Standard

Popular

$99/mo

Users: N/A

Storage: Based on deployment

Limits: Standard support only, some ML features require higher tier

Data transfer, API calls, snapshots at scale. Pricing scales with deployment size.

Elastic Cloud Gold

$114/mo

Users: N/A

Storage: Based on deployment

Limits: Still usage-based, enterprise features in higher tiers

Same scaling costs as Standard, support upgrade cost

Elastic Cloud Enterprise

$0/mo

Users: N/A

Storage: Custom

Limits: Requires sales engagement, pricing varies widely

Enterprise pricing negotiated. 'Mid-sized deployments $100-500/mo, enterprise thousands per month.'

Weaviate

Self-Hosted (Open Source)

Free

Users: Unlimited

Storage: Limited by your infrastructure

Limits: No managed operations, manual scaling, no enterprise support, requires DevOps expertise

You pay for infrastructure. Memory-intensive workloads need significant compute. No SLA or support.

Flex (Shared Cloud)

Free

Users: Unlimited

Storage: Pay per vector dimension

Limits: Shared infrastructure, limited customization vs Dedicated

Pricing varies by vector dimensions, storage, backups, region. Use calculator. Costs can surprise at scale.

Plus (Annual)

Free

Users: Unlimited

Storage: Committed capacity

Limits: Locked into annual contract

Requires upfront annual commitment. Contact sales for exact pricing.

Dedicated Cloud

Free

Users: Unlimited

Storage: Dedicated resources

Limits: Higher minimum spend, longer provisioning time

Premium over Shared Cloud. Custom pricing based on resources. Contact sales.
