In-Depth Review: What is Tigris?
Tigris is a modern object storage platform designed for developers and AI agents. It offers bottomless storage with zero egress fees, S3 API compatibility, and global redundancy. Key features include zero-copy forks for experimentation, snapshots for time travel, webhooks for event-driven pipelines, and fine-grained IAM. Tigris also provides an Acceleration Gateway for local caching to boost AI training and inference performance. With zero-downtime migration from existing S3-compatible storage, Tigris eliminates vendor lock-in and simplifies data management at scale.
Core Features
Zero Egress Fees
No charges for data transfer out to the internet or between regions, enabling cost-effective storage and distribution.
Bottomless Storage
Store unlimited amounts of data with no per-account or per-region limits, automatically scaling as needed.
S3 Compatibility
Native S3 API support allows using existing tools like boto3, aws-cli, and rclone without code changes.
Copy-on-Write Forks
Create instant, zero-copy forks of buckets for isolated experimentation, agent sandboxes, or parallel workflows.
Global Geo-Redundancy
Data is automatically redundant across regions with placement options (single, multi, global) for low-latency access worldwide.
Snapshots & Time Travel
Take whole-bucket snapshots for point-in-time recovery, rollback, or auditing with second-level precision.
Acceleration Gateway
A local caching proxy that delivers near-local NVMe throughput for AI training and inference, compatible with any S3 client.

Pros and Cons
Pros
- No Egress FeesEliminate data transfer costs, making it ideal for AI/ML workloads with high read volumes across regions.
- Infinite ScalabilityNo storage limits or capacity planning required; scales automatically from gigabytes to petabytes.
- S3 Compatible APIWorks with existing S3 tools and SDKs out of the box, minimizing migration effort.
- Global PerformanceData automatically distributed worldwide for low-latency access, with optional placement controls.
- Purpose-Built AI FeaturesCopy-on-write forks, snapshots, and webhooks enable advanced agent workflows and experimentation.
Cons
- Limited Free TierFree tier only includes 5 GB of storage and limited requests, which may not suffice for larger evaluations.
- Archive Retrieval ComplexityAccessing Archive tier data requires restoration to Standard tier, adding latency and potential costs.
- No Per-Region Pricing ControlPricing is uniform globally, so users with single-region needs may pay for global features they don't use.
- Relatively New ServiceTigris is a newer platform compared to AWS S3 or GCS, which may concern enterprises requiring long-term stability.
- Dependency on CoreWeave InfrastructureThe Acceleration Gateway relies on CoreWeave's network, which might limit flexibility for some hybrid setups.
