Filestash

Filestash is a web-based file manager that lets you browse, upload, download, preview, and share files from many existing backends (such as SFTP, WebDAV, S3-compatible object storage, FTP, and SMB). It is designed as a single, user-friendly web UI in front of heterogeneous storage systems, with optional capabilities like in-browser editing and access control.

Key Features

• Connects to multiple storage backends (commonly including SFTP, FTP/FTPS, WebDAV, SMB, and S3-compatible object storage)
• Modern web file manager UI: folder navigation, search, uploads, downloads, rename/move/copy, and bulk actions
• File previews for common formats (images, video/audio in-browser when supported, text, PDFs)
• Share functionality (public/shared links) and access controls depending on backend and configuration
• Optional online editing and collaborative editing via integrations (e.g., OnlyOffice)
• Authentication options and configuration for multi-user environments
• Runs as a single web app (often deployed via Docker) acting as a gateway to existing storage

Use Cases

• Provide a browser-based UI for SFTP-only servers to non-technical users
• Unified access portal for mixed storage (e.g., S3 + SMB + WebDAV) inside an organization
• Lightweight alternative to “cloud drive” UIs to browse and share files without migrating storage

Limitations and Considerations

• Feature depth (permissions, versioning, advanced sharing) depends on the underlying storage backend and configured connectors
• Some advanced capabilities (e.g., office-suite collaboration) require external services/integrations

Filestash is well-suited when you already have storage in place and want a clean web interface, previews, and convenient sharing on top. Its connector-based approach makes it practical for teams managing multiple protocols and storage systems without forcing data migration.
