S3 API Compatibility | Tigris Object Storage Documentation
Tigris S3 API Compatibility
Tigris is compatible with the AWS S3 API. You can use the standard AWS S3 SDKs, tools, and libraries with Tigris.
The compatibility data on this page is generated by running the same test suite against each provider using the AWS JS SDK v3. The suite includes both a TypeScript runner and a Go runner (AWS Go SDK v2). The results below use the TypeScript runner, which has broader provider compatibility. Each run creates a temporary bucket, executes all operations, and reports pass/fail results.

Notes
- Encryption: Tigris encrypts all data at rest automatically. The bucket encryption configuration APIs accept requests but server-side encryption with managed keys is always on.
- Canned ACLs: Only canned ACLs (
public-read and private) are supported.
- Conditional copy: R2 supports UploadPartCopy but does not support conditional copy operations (
x-amz-copy-source-if-match, etc.).
- GCS ACL model: GCS uses a different ACL permission model where permissions are concentric (WRITE implies READ). S3-style ACL XML is accepted but behavior differs from AWS S3.
- GCS versioning: GCS maps versioning to its own generation number system, which differs from S3 version IDs.
