File Browser is a self-hosted application that provides a web-based interface for managing files and directories on a server. It functions as a virtual file system abstraction, allowing users to browse, organize, and edit text-based files directly within their browser without requiring local access to the server. The platform distinguishes itself through a comprehensive command-line interface that enables full administrative control over system configurations, user accounts, and automation hooks. It supports a flexible, event-driven architecture where custom shell scripts can be triggered aut

fsnotify is a cross-platform filesystem notification library that provides a programming interface for tracking file and directory changes within Go applications. It utilizes native kernel notification interfaces to detect events such as file creation, deletion, and attribute updates, allowing developers to integrate real-time monitoring into their software. The library distinguishes itself by providing a unified abstraction layer that normalizes disparate kernel APIs into a consistent event stream. It manages high-volume activity through non-blocking event polling and internal memory bufferi

A Go package for media type and file extension detection, based on magic numbers

Duplicacy is a cross-platform, deduplicated backup tool that stores encrypted snapshots to local disks and cloud storage services. It operates through both a command-line executable and a web-based graphical interface, enabling backup, restore, and repository management in scripts or through a browser. The software splits files into variable-size chunks identified by their hash, enabling cross-machine deduplication without a central database or chunk index. Each backup creates an immutable snapshot that stores file metadata and chunk references, supporting incremental updates and point-in-tim

Fast, dependency-free Go package to infer binary file types based on the magic numbers header signature

CasaOS is a lightweight software stack designed to transform standard Linux distributions into a comprehensive personal cloud platform. It functions as a management layer that sits atop the host operating system, providing a unified graphical dashboard to deploy, monitor, and administer containerized applications and local hardware resources. By automating the lifecycle of isolated software services, it enables users to maintain a private and secure digital infrastructure on their own hardware. The platform distinguishes itself through a declarative configuration model that continuously recon

MinIO is a software-defined, cloud-native object storage server designed to manage large volumes of unstructured data. It functions as a distributed storage cluster that aggregates multiple independent nodes into a unified, scalable pool, providing a high-performance infrastructure compatible with standard cloud storage protocols and application programming interfaces. The system utilizes a shared-nothing architecture that eliminates central metadata servers, relying instead on a decentralized hash table to map objects across the cluster. Data availability and resilience are maintained throug

Go copy directory recursively

This project is a command-line storage manager that provides a unified interface for performing file operations across local filesystems and diverse cloud storage providers. It functions as a cross-platform storage abstraction, utilizing a modular backend architecture to map heterogeneous cloud storage APIs into a standard set of file system operations. This allows for consistent data management and movement regardless of the underlying storage service. The tool serves as a network data transfer engine designed for automated data migration and cloud storage synchronization. It distinguishes i

This project is a command-line utility designed for secure, content-addressable data archiving. It functions as an encrypted backup tool that stores data as deduplicated chunks, ensuring that every piece of information is identified by a cryptographic hash to maintain integrity across all backups. By applying strong encryption and message authentication codes to both data and metadata, the software prevents unauthorized access and detects potential tampering. The tool distinguishes itself through a backend-agnostic storage abstraction that allows users to maintain repositories across diverse

gocryptfs is a FUSE-based encrypted filesystem that transparently encrypts and decrypts file contents and filenames on disk. It uses block-level authenticated encryption with AES-GCM or AES-SIV-512, binding each block to its file header and offset for integrity, while obfuscating filenames with EME or AES-SIV wide-block ciphers using per-directory initialization vectors. The system derives all encryption keys and initialization vectors deterministically from a master key using HKDF and SHA256, enabling reproducible ciphertext for reliable backup and synchronization workflows. The project dist

A simple library for generating PDF written in Go lang

go-fastdfs is a distributed file system and object storage server designed for building private cloud storage. It provides a FastDFS compatible storage implementation that manages clusters of storage nodes to handle large-scale file uploads and downloads. The system focuses on high availability through a decentralized architecture that automatically synchronizes data and repairs failures across multiple machines without a central coordinator. It specifically supports resumable file storage via HTTP, allowing large transfers to be paused and resumed from the last successful byte to handle netw

Afero is a Go library that provides a unified filesystem abstraction, allowing applications to interact with local disk, in-memory storage, cloud services, archives, and remote systems through a single, consistent interface. At its core, it defines a standard interface that all filesystem backends implement, enabling developers to swap storage implementations without changing application code. The library distinguishes itself through its composable architecture, which includes layered filesystem composition for creating cached, sandboxed, or restricted storage views. It offers a copy-on-write

Syncthing is a decentralized file synchronization engine that maintains consistent data states across multiple devices through peer-to-peer mesh networking. It operates as a background daemon that automatically replicates file creations, modifications, and deletions between trusted nodes without requiring central servers. By utilizing content-addressable block indexing and block-level delta synchronization, the system identifies and transfers only the modified segments of files, ensuring efficient data propagation across heterogeneous environments. The project distinguishes itself through a s

lakeFS is a data lake versioning system that provides Git-like branching and commits for large datasets stored in object storage. It functions as a version control layer, enabling the creation of immutable snapshots, atomic commits, and zero-copy branching to create isolated environments for data experimentation without duplicating physical files. The system serves as an S3-compatible storage gateway and an Iceberg REST catalog, allowing standard cloud storage protocols and compatible clients to manage versioned tables. It acts as a data quality gatekeeper by using an event-driven hook system

Golang PDF library for creating and processing PDF files (pure go)
