FileRun

FileRun is a web-based file manager you install on your own Linux server. It gives you a browser interface for uploading, organizing, previewing, and sharing files, plus desktop and mobile sync clients so your team can access files from anywhere. Unlike many self-hosted options, FileRun focuses on being fast and easy to use, with a clean interface that feels familiar to anyone who has used cloud storage.

The software integrates directly with Nextcloud desktop and mobile sync apps, so you can use those clients to sync files to a FileRun server. It also supports Elasticsearch for full-text search inside documents, images, and PDFs. FileRun works with S3-compatible storage, FTP, and local drives, and includes built-in photo albums, video streaming, and document editing through Collabora Online or OnlyOffice.

FileRun is developed by a small Romanian company called FileRun SRL. The core software is free and open source under the AGPLv3 license, with paid support and enterprise features available. It is a solid pick for small businesses or tech-savvy individuals who want cloud-like file management without trusting a third party with their data.
