BentoS3: a lightweight S3-compatible server for local development and tests

s3testingdevelopmentopensource

BentoS3, a lightweight S3-compatible server for local development, automated tests, and CI environments, has reached its first stable version. The project was created by a developer who found MinIO's free version lacking after its direction changed and features were removed. BentoS3 is designed to be embeddable, eliminating the need for containers in integration tests, which reduces setup cost and speeds up feedback loops. It implements a practical subset of the S3 API based on common usage patterns, and the author is open to improving compatibility over time. BentoS3 is not intended for production use but as a local development and testing tool. The project is open source and available on GitHub.

// why it matters

Simplifies local S3 testing by removing container dependencies.
