Locker review
A flexible file workspace for teams willing to manage their own hosting and storage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Locker is an open-source file storage platform that teams and individuals can deploy on their own infrastructure. Its web interface supports uploading, organizing, searching, and sharing files, while workspace roles give teams a way to manage access. The product suits organizations that want a file workspace backed by storage they control, rather than a hosted subscription service. It is also available through an API, including a type-safe tRPC API, for teams that need programmatic access.
Storage flexibility is a central part of Locker's design. Workspaces can use a local filesystem, AWS S3, Cloudflare R2, or Vercel Blob, and multiple backends can be attached to a workspace for replication. Search covers file names and content, with document transcription for images and PDFs. Previews cover PDFs, images, Markdown, CSV, audio, video, and plain text. Share links can include password protection, expiration dates, and download limits; upload links let people send files without an account. A virtual filesystem shell includes commands such as ls, find, cat, and grep. Google OAuth and Google Drive are also listed integrations.
Locker is free and open source, but that does not remove the operational cost of running it: users pay for hosting and storage infrastructure. Its self-hosted approach is a fit for teams prepared to manage that environment and choose their storage setup. It is less suitable for buyers seeking a managed service with verified sync clients or version history, since those are not part of the stated offering. Choose Locker for storage-backed workspaces, sharing, and backend flexibility; consider alternatives if synchronization across devices or file version history is essential.
