FileRise is a self-hosted web file manager and storage hub with WebDAV, sharing, and per-folder ACLs. The backend is PHP 8.3+ with Apache, using flat-file storage (no database) and a REST API. The frontend is a modular vanilla JS SPA with i18n, dark mode, and drag-and-drop. It supports multi-source storage (local, S3, SFTP, WebDAV, etc.), encryption at rest (libsodium), TOTP 2FA, OIDC SSO, and background workers for transfers and ZIP creation. A commercial Pro add-on provides AI chat, client portals, automation, and advanced storage sources. The codebase is actively maintained with frequent releases and a comprehensive security regression test suite. While the architecture is clean with well-defined interfaces (storage adapter, ACL, encryption), there is some legacy debt from a namespace migration and monolithic domain models.
