Future-proof content collaboration platform
Pydio Cells is a self-hostable content collaboration platform that provides file synchronization, sharing, encryption, cross-platform clients, and an admin dashboard, making it a direct equivalent to a private Dropbox or Google Drive for your needs.
Spacedrive is a decentralized storage client that functions as a distributed file manager, aggregating local, cloud, and network storage into a single virtual filesystem. It operates on a local-first design, prioritizing offline availability by caching metadata and file chunks locally before synchronizing them across devices. By coordinating data access without relying on a central server, it enables users to maintain a private and secure storage network across their own hardware and cloud accounts. The platform distinguishes itself through a virtual storage layer that maps disparate physical
Spacedrive is a decentralized storage client that syncs files across your own devices and cloud accounts, making it a self-hosted alternative to Dropbox or Google Drive—it covers file synchronization, encryption, and cross-platform clients, though it lacks a traditional admin dashboard and explicit file-sharing features.
Copyparty is a self-hosted file server that provides a browser-based interface for managing, browsing, uploading, and downloading files. It utilizes a virtual file system abstraction to map diverse storage backends and network-attached devices into a unified directory structure, allowing for consistent file access across various storage environments. The platform functions as a cloud synchronization gateway, enabling automated data backups and transfers between local storage and remote cloud providers through integration with standard command-line tools. It also serves as a distributed storag
Copyparty is a self-hosted file server and cloud synchronization gateway that enables file sharing and automated backups, fitting the private cloud storage intent, but it lacks dedicated native clients and built-in encryption typically found in full-featured Dropbox alternatives.
Cloudreve is a self-hosted cloud storage platform designed to provide personal and organizational file management. It functions as a web-based solution that allows users to store, organize, and share digital files across multiple devices while maintaining control over their own data infrastructure. The platform distinguishes itself through a storage backend abstraction layer, which provides a unified interface to manage files across diverse local and remote cloud providers. It incorporates a robust identity and authorization layer that supports standard OAuth 2.0 flows for secure third-party
Cloudreve is a self-hosted web-based cloud storage platform that manages files and sharing across devices with storage backend abstraction, fitting the Dropbox-like intent, though dedicated sync clients and encryption are not explicitly highlighted.
This project is a multi-device synchronization tool and remote storage manager that maintains a mirrored state of data between a local machine and a remote server. It provides cloud file synchronization and cross-device data access, allowing local files and folders to be consistent across multiple computers. The client utilizes WebDAV for file management and synchronization, while employing the Open Collaboration Services API for account and session management. It integrates a cross-platform native wrapper to provide OS-level file system integration and includes a command line interface for m
Nextcloud Desktop is the client sync tool for the Nextcloud ecosystem, but the visitor is seeking a full self-hostable platform—the server component—so this repo alone doesn't satisfy that intent.
SyncTrayzor is a native Windows tray wrapper and management interface for Syncthing. It functions as a process manager that ensures the synchronization service starts automatically upon user login and remains active in the background. The project provides a built-in browser to render the Syncthing web interface and includes a specialized conflict resolver tool to identify and fix versioning mismatches between synchronized files. It integrates directly into the system tray to provide service status updates and desktop notifications. Capability areas include synchronization monitoring for trac
SyncTrayzor is a Windows tray wrapper and process manager for Syncthing, not a self-hosted cloud storage platform—it only manages Syncthing on one OS and does not provide file sharing, encryption, or an admin dashboard.
This is a command-line client for managing multiple Aliyun Drive accounts from a single interface. It authenticates each account via an OAuth browser-based login flow, stores tokens separately, and allows switching between active sessions. The tool unifies local and cloud file paths under a common tree structure, enabling consistent browsing, upload, download, and organization across all connected accounts. The client implements several techniques to accelerate and control file transfers. Downloads are split into chunks and transferred concurrently across multiple streams, with progress track
This is a command-line client for managing multiple Aliyun Drive accounts, not a self-hostable platform—you rely on Aliyun's proprietary servers rather than hosting your own cloud storage and sync solution like Dropbox or Google Drive.
Remotely Save is a cloud storage synchronization tool and backup manager designed to keep local files and application data consistent across desktop and mobile devices. It functions as a cross-platform synchronizer that mirrors local data to remote servers using S3 and other cloud protocols. The project focuses on privacy and security through end-to-end encryption, which secures files with a user-defined password before they are uploaded to remote cloud services. It ensures data remains private on third-party servers by applying symmetric client-side encryption. The system includes capabilit
Remotely Save is a client-side synchronization tool that encrypts and syncs local files to remote cloud storage like S3, not a self-hosted server platform with file sharing and an admin dashboard — it fits as a component but not the full platform you want.
WebClient is an encrypted productivity suite consisting of integrated web tools for secure email, calendar, drive, and password management. It serves as an end-to-end encrypted email client, a secure cloud storage interface, and a private calendar management application. The project includes specialized interfaces for a variety of secure services, including a web-based VPN controller, a secure cryptocurrency wallet interface, and an encrypted video conferencing client for real-time audio and video meetings. The suite covers broader capabilities for managing digital identities, organizing enc
This repository is the web-client frontend for Proton's encrypted productivity suite, not a self-hostable server platform — it lacks the backend needed to deploy and manage your own cloud storage and file synchronization service.
