Summary

What it is

An S3-compatible cloud storage service with a fixed pricing model — no egress fees, no API request fees, approximately $5–7/TB/month with a 90-day minimum storage retention policy.

Where it fits

Wasabi is the cost-optimized S3-compatible cloud tier for workloads where egress and API costs dominate the bill. It sits alongside Cloudflare R2 and Backblaze B2 as a zero-egress alternative to AWS S3, but with a distinct pricing model — flat rate per TB with no per-request charges, at the cost of a minimum retention floor.

Misconceptions / Traps
  • Zero egress is not zero cost. The 90-day minimum retention means deleting data before 90 days still incurs charges for the full period. This penalizes short-lived or frequently-replaced datasets.
  • Wasabi is S3-compatible but not feature-complete with AWS S3. Advanced features like S3 Select, S3 Inventory, and S3 Event Notifications are not available.
  • No native compute integration. Unlike AWS S3 with Athena/Glue or S3 Tables, Wasabi is pure storage — you must bring your own query engine.
Key Connections

Definition

What it is

A single-tier S3-compatible cloud storage service with zero egress fees and zero API request fees, priced at approximately $5–7/TB/month. Enforces a 90-day minimum storage retention policy.

Why it exists

Hyperscaler egress fees make multi-cloud and hybrid architectures prohibitively expensive. Wasabi's flat pricing model eliminates egress and API call costs, making it viable for backup, compliance archival, and any workload where data is read frequently from outside the provider's network.

Primary use cases

Backup and disaster recovery targets, compliance archival with predictable costs, secondary storage for multi-cloud pipelines, S3-compatible storage for cost-sensitive workloads.
