Alternatives to MinIO for single-node local S3

MinIO, a popular tool for emulating S3 storage in local development environments, was abandoned by its company in late 2025, prompting the need for alternatives. This article evaluates replacement options that must offer Docker support, S3 compatibility, free/open-source licensing, and simple single-node deployment for demos and development pipelines. The author establishes criteria for suitable replacements and provides a baseline test setup using DuckDB, Iceberg, and MinIO to benchmark alternatives against.
