Tigris
Globally-distributed S3-compatible object storage service that automatically replicates objects close to the regions writing them and pulls them closer to readers based on observed traffic patterns. Drop-in for existing AWS S3 / GCS SDKs — most teams adopt by setting an endpoint and access key without code changes. Storage classes: Standard, Infrequent Access, Archive Instant, Archive. Public-cloud-grade durability without the per-region cost-management overhead of multi-region AWS S3.

Globally-distributed S3-compatible object storage service that automatically replicates objects close to the regions writing them and pulls them closer to readers based on observed traffic patterns. Drop-in for existing AWS S3 / GCS SDKs — most teams adopt by setting an endpoint and access key without code changes. Storage classes: Standard, Infrequent Access, Archive Instant, Archive. Public-cloud-grade durability without the per-region cost-management overhead of multi-region AWS S3.
AWS S3 charges per-region for both storage AND egress, which makes "objects accessed globally" economically painful — every cross-region pull is a billed egress event. Tigris's bet is: pay once for storage, pay zero for egress, and let the platform handle the placement decisions automatically. For workloads like CDN origins, ML training-data distribution, and media streaming — where egress dominates TCO — this collapses the cost curve. The trade-off is less granular control over object placement and replication topology.
CDN origin storage where egress would dominate AWS S3 bills, AI/ML training-data distribution across geographies, multi-region SaaS storage backends, media streaming where global low-latency reads matter, and developer-tier projects where the 5GB free tier covers prototypes.
Recent developments
- Durable global streams via S2 integration. Tigris shipped an S2 (S3 over Streams) integration that turns Tigris buckets into globally-durable append-only log streams — useful for distributed event sourcing and as a Kafka-cheaper-replacement for cross-region pipelines. Per Tigris blog.
- Storage classes expanded 2 → 4: Archive Instant + Archive added. Tigris now offers Standard, Infrequent Access, Archive Instant, and Archive tiers, with no per-region cost differences and no egress fees on any tier. Per Tigris pricing.
- Truly unlimited free egress (no caveats). Per the 2026 S3-compatible provider comparison, Tigris remains one of the few S3-compatible providers offering unlimited free egress without bandwidth caps or burst-rate gotchas. Per Mixpeek — Best S3-Compatible Object Storage 2026.
- Fly.io platform integration. Tigris is the default object-storage backend for Fly.io's app platform, integrated via the Fly CLI for one-command bucket provisioning tied to an app. Per Fly.io docs.
- S3 SDK drop-in adoption pattern. Per the DEV Community writeup, most teams adopt Tigris by reconfiguring existing AWS S3 or Google Cloud Storage SDKs with new endpoints + access keys — no code changes beyond configuration.
