Zenko CloudServer is an open-source, Amazon S3-compatible object storage server written in Node.js. It exposes a single S3 API while storing data across multiple backends, including local disk, memory, and cloud providers, and is commonly used to emulate S3 locally for development and testing.
Use cases
- run a local S3-compatible server for development and testing
- emulate AWS S3 in a CI test environment
- expose a single S3 API over multiple cloud storage backends
- self-host an S3-compatible object storage service
- develop S3-based applications without an AWS account
- abstract storage across on-premise and public clouds
When to choose
- you need an S3 API endpoint without paying for or depending on AWS
- you want to test S3-integrating code locally or in CI
- you need a multi-cloud storage abstraction behind one S3 interface
- you want a self-hosted, Docker-deployable object store
When to avoid
- you need production-grade, petabyte-scale storage with vendor support (consider Scality RING or a managed S3)
- you need block or file storage rather than object storage
- you require full parity with every AWS S3 feature
- you want a non-Node.js stack or a lightweight embedded option
