Files SDK - A Single API for All Blob Storage

An SDK that lets you handle 29 types of object/blob storage including S3, R2, GCS, Azure, and more through a single unified interface. It supports 40+ adapters, allowing you to switch storage environments simply by swapping adapters while keeping all your calling code intact.

It is especially specialized for serving as a file tool for AI agents, providing file handling capabilities for Vercel AI SDK, OpenAI Agents, Claude, MCP (Model Context Protocol), and more.

Key features include the following:

• Unified Interface: Core operations such as upload, download, copy, move, list, and delete are called the same way across all adapters, while also providing an escape hatch to use native clients when needed.
• High-Performance Processing: Supports array-based rate-limited concurrent batch processing and parallel multipart uploads.
• Real-Time Monitoring and Control: Enables real-time upload progress via callbacks and ranged reads (video seeking, resumable downloads, etc.) through HTTP 206 mapping.
• Data Synchronization: The sync() method lets you mirror data from one backend to another, with support for reflecting only the changes.
• Lifecycle Management: The onAction, onRetry, and onError hooks allow unified management of the lifecycle of every operation.
