obspec
Object storage interface definitions for Python.
Decision gist · record as of 2026-08-14
Yes, if you are building or using tools that need to work with object storage across multiple providers. The protocol is actively maintained, has no security vulnerabilities, and installs with minimal friction. However, verify that an implementation is available for your use case, as obspec alone defines the interface rather than providing storage operations.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; obspec defines protocols but requires a backend implementation to perform actual storage operations.
- Low friction to install.
- The package is actively maintained with recent commits and depends only on typing-extensions, distributed as a pure Python wheel.

What it is and what it does
obspec is a Python protocol library that defines a standard interface for object storage operations. Rather than treating object storage like a filesystem, it acknowledges that cloud storage has fundamentally different semantics—more similar to HTTP requests than file objects. The package provides the protocol definitions that allow different object storage backends to implement a common API.
The library is designed to work with implementations that provide the actual storage operations. By defining a generic protocol, obspec enables utilities and tools built on top of it to work with any conforming backend without needing provider-specific code. The project is in active development with planned utilities for globbing and caching built on the protocol primitives.
Use it for
- Building storage-agnostic applications that work with multiple providers without vendor lock-in
- Creating tools and utilities that operate on object storage without reimplementing provider-specific logic
- Standardizing object storage interfaces within organizations using multiple cloud platforms
- Developing libraries that need to abstract over different object storage backends
