Files SDK

Files SDK, built by developer Hayden Bleasel, is a unified storage abstraction layer that enables developers to write file storage code once and deploy it across multiple cloud providers, providing a consistent API for uploading, downloading, listing, and managing files regardless of the underlying storage backend. It offers multi-provider support working with S3, R2, GCS, Azure, and more than 40 other object or blob store adapters, a unified API for operations like upload, download, delete, copy, and move, and search capabilities using glob patterns, regex, or substring matching. Files SDK includes multipart uploads with configurable concurrency, byte-level progress tracking during uploads, byte-range downloads for seeking and streaming file segments, and pre-built AI agent integration tools for the Vercel AI SDK and Claude. It also offers CLI support for command-line operations, lifecycle hooks for metrics and error reporting, and sync functionality for mirroring data between backends, currently at version 2.2.5. Pricing is open source under the MIT license, freely available with no commercial restrictions.
