What Nubbo does

Nubbo is a Spain-based, founder-operated web platform that provides a single unified interface for managing files across multiple S3-compatible cloud storage providers. Users connect their own accounts at AWS S3, Cloudflare R2, DigitalOcean Spaces, Wasabi, Backblaze B2, or any S3-compatible self-hosted server (MinIO, Ceph, Garage, SeaweedFS) and browse, upload, share, preview, and organize files from one dashboard. The product targets freelancers, creatives (photographers/videographers), developers, privacy-conscious individuals, and small teams, with particular emphasis on use cases such as client deliverable management, professional photo/video galleries, and file-request inboxes for receiving uploads from third parties.

The platform's defining architectural choice is a zero-knowledge model: files are transferred directly between the user's browser and the chosen cloud provider via presigned URLs and never traverse Nubbo's infrastructure. Provider credentials are encrypted at rest with AES-256-GCM using a key stored as an environment variable, and share/request passwords are bcrypt-hashed. Built-in modules include a file explorer with drag-and-drop uploads, a media player (video and audio with playlists, speed control, picture-in-picture), a Monaco-based code and Markdown editor, password-protected share links with expiration and download limits, upload-only file request links, and branded photo/video galleries with watermarks and engagement tracking. A June 2026 release added server-side and browser-mediated file transfer between buckets, accounts, and different cloud providers.

Commercially, Nubbo is currently offered entirely free, with a stated roadmap of paid tiers (Personal, Pro, per-seat Teams, and negotiated Custom enterprise contracts) that will introduce zero-knowledge encryption for folders/files, public API access, webhooks, embeddable components, SSO, roles and permissions, audit logs, Slack/Trello integrations, and AI/automations. The company is registered as a sole proprietorship owned by Gonzalo Vasco López in Lugo, Spain, with no disclosed external funding. Go-to-market is product-led: SEO-optimized provider setup guides and comparison content drive organic acquisition, with a self-serve web signup funnel and no sales team. Core infrastructure dependencies are Prisma Data (managed Postgres in EU-Frankfurt) for application data and Resend for transactional email.

Core offering

Nubbo is a unified cloud storage management platform that connects to multiple S3-compatible object storage providers (AWS S3, DigitalOcean Spaces, Cloudflare R2, Wasabi, Backblaze B2, and any S3-compatible or self-hosted server) through a single web-based interface. The platform uses presigned URLs to transfer files directly between users' browsers and cloud providers, meaning files never pass through Nubbo's servers. It provides file browsing, media playback, file sharing with access controls, file request upload links, and professional photo/video galleries, with credentials protected by AES-256-GCM encryption.

Broad incumbents

• Dropbox: Mass-market cloud storage and file sharing incumbent with native galleries, sharing controls and team features. Comparable on sharing/collaboration UX for the SMB segment; differs fundamentally in owning the storage layer.

Direct peers

• Cyberduck: Cross-platform (macOS/Windows) S3-compatible file browser with a long-standing user base. Directly comparable to Nubbo as an S3 management tool for end users, though Cyberduck is a desktop client rather than a web app and lacks Nubbo's zero-knowledge architecture.
• Mountain Duck: Cyberduck's sister product from Iterait, mounts S3-compatible storage as a local drive on macOS/Windows. Targets a similar user base seeking unified multi-provider access but via OS-level mount rather than web app.
• MSP360 (formerly CloudBerry): Cloud storage management and backup platform with broad S3-compatible provider support and paid SMB/enterprise tiers. Direct competitor for the Pro/Teams/Custom segments Nubbo's roadmap targets, with much larger feature surface.
• S3 Browser: Windows S3 client used by individual developers and admins to manage AWS S3 and compatible buckets. Competes for the same freelance/IT user Nubbo targets, but is desktop-only and AWS-centric.
• Filebrowser: Self-hosted web file manager popular with developers and SMBs. Comparable as a web-based file management layer, though typically deployed on local storage rather than connecting to multiple external S3 providers.
• Filestash: Open-source web-based file manager that connects to S3, SFTP, FTP, WebDAV and more. The closest direct comparable to Nubbo in product shape (web-based, multi-provider S3 browser) and includes sharing, photos and media preview features.

Emerging players

• Rclone: Open-source CLI for syncing and managing 50+ cloud storage backends, widely used by developers. Adjacent to Nubbo for the developer segment; less comparable in UX but the dominant tool for power-user cloud storage workflows.
• PicTime: Photography gallery, proofing and delivery platform popular with professional photographers. Comparable for the creative/professional-gallery use case Nubbo targets, but coupled to PicTime's own storage and sales workflow.
• Filestage: Cloud-based file review, approval and proofing platform used by agencies and creative teams. Overlaps with Nubbo's gallery and file-request features for the creative/freelancer segment, but focuses on approval workflows rather than storage management.
