Versity S3 Gateway is an open source Apache 2.0 licensed tool that translates S3 object storage to file system interfaces, enabling S3-based applications to work with file-based storage systems. Developed collaboratively by Versity, Los Alamos National Laboratory, and Pawsey Supercomputing Research Centre, it aims to provide high-performance, scalable storage capabilities for demanding workloads.
go-duckfs is a Go package that mounts io/fs read-only file systems as backends for DuckDB databases, routing all I/O operations through the Go runtime to leverage pure Go packages and avoid C++ extension limitations. It requires dynamic linking with DuckDB and allows virtual paths with protocol prefixes to be queried using DuckDB's read functions.
Proton Drive for Linux is an unofficial FUSE virtual filesystem that mounts Proton Drive as a local folder, downloading files on demand and syncing remote changes through Proton's event feed. The project is in early development with basic read, write, create, delete, rename and move operations tested on a single share, but users should expect bugs.
Mastra's new @mastra/mainbrella package unifies agent tools by running them in a shared Linux container, solving synchronization issues where file-writing and command-execution tools operate on different filesystems. The package provides a sandbox, HTTP filesystem, and editor provider, with a process manager that maintains job state even when connections drop, allowing agents to write scripts, execute them, and inspect results without infrastructure complexity.
