{"library":"s3fs","type":"library","category":null,"description":"S3Fs is a Pythonic filesystem interface to Amazon S3, built on top of aiobotocore and fsspec. The top-level class S3FileSystem exposes familiar file-system operations (ls, cp, mv, du, glob, put, get) and a file open() API that emulates Python's standard file protocol, making it a drop-in for libraries like pandas, dask, and gzip that accept file-like objects. It also supports S3-compatible stores (MinIO, Ceph, R2) via the endpoint_url parameter. Versions follow calendar versioning (YYYY.MM.PATCH); the current release is 2026.2.0, released February 2026, with roughly monthly cadence.","language":"python","status":"active","version":"2026.2.0","tags":["aws","s3","filesystem","fsspec","aiobotocore","async","cloud-storage","pandas","dask"],"install":[{"cmd":"pip install s3fs","imports":["import s3fs\ns3 = s3fs.S3FileSystem()","with s3fs.S3FileSystem().open('bucket/key', 'rb') as f: ...","import fsspec\nwith fsspec.open('s3://bucket/key', 'rb') as f: ..."]},{"cmd":"pip install 's3fs[boto3]'","imports":[]},{"cmd":"conda install -c conda-forge s3fs","imports":[]}],"homepage":null,"github":"http://github.com/fsspec/s3fs","docs":null,"changelog":null,"pypi":"https://pypi.org/project/s3fs/","npm":null,"openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"3.10–3.9","success_rate":100,"avg_install_s":6.4,"avg_import_s":1.07,"wheel_type":"wheel"},"url":"https://checklist.day/v1/registry/s3fs/compatibility"},"provenance":{"verified_status":"passing","verified_at":"Sat Jun 27","last_verified":"Sat Jun 27","next_check":"Mon Jul 27","install_tag":"verified"}}
