Self-Hosted Digital Asset Management: ResourceSpace vs Pimcore vs Mayan EDMS

Organizations generate and manage thousands of digital assets — images, videos, design files, product photos, marketing materials, and documents. Without a centralized system, finding the right file version, managing access permissions, and maintaining metadata becomes a daily struggle. Digital Asset Management (DAM) platforms solve this by providing a single source of truth for all digital content.

While commercial DAM solutions like Bynder, Adobe Experience Manager, and Brandfolder charge premium prices, open-source alternatives offer full self-hosted control, no per-user licensing fees, and complete customization. This guide compares three leading open-source DAM platforms: ResourceSpace, Pimcore, and Mayan EDMS.

What Is Digital Asset Management?

A DAM platform is a centralized system for storing, organizing, retrieving, and distributing digital assets. Core capabilities include:

• Centralized storage: Single repository for all digital files with version control
• Metadata management: Tags, descriptions, copyright info, and custom fields
• Search and discovery: Full-text search, faceted browsing, and visual search
• Access control: Role-based permissions, download restrictions, and usage tracking
• Format conversion: Automatic image resizing, video transcoding, and format conversion
• Workflow management: Approval processes, review cycles, and collaboration tools
• Integration: APIs and connectors for CMS, e-commerce, and marketing tools

Self-hosted DAM solutions are ideal for organizations that need data sovereignty, have large asset libraries, or want to avoid recurring SaaS subscription costs.

ResourceSpace

ResourceSpace is a mature, open-source DAM platform designed for organizations that need a straightforward, feature-rich asset management system. It has been in development since 2006 and is used by universities, NGOs, museums, and enterprises worldwide.

Architecture

ResourceSpace is a PHP-based web application with a traditional LAMP/LEMP stack:

• PHP Application: Web-based interface for asset management
• MySQL/MariaDB: Metadata, user accounts, and collection data
• Filesystem or S3: Asset storage (local disk, NFS, or cloud storage)
• ImageMagick / FFmpeg: Automatic thumbnail generation and video preview
• Elasticsearch (optional): Enhanced full-text search capabilities

Choosing the Right DAM Platform

Each platform serves a different primary use case:

ResourceSpace is the best choice for organizations that need a dedicated, easy-to-use DAM system for managing media assets. It excels at photo libraries, marketing material repositories, and creative asset management. The straightforward setup and intuitive interface make it accessible to non-technical users.

Pimcore is the right choice when you need more than just asset management. If you also need product information management, content management, or master data management, Pimcore consolidates all these capabilities into a single platform. It is ideal for e-commerce organizations and enterprises managing complex product catalogs alongside marketing assets.

Mayan EDMS is the best choice for document-centric workflows. If your primary need is managing contracts, invoices, legal documents, or compliance records — especially with OCR and automated workflow routing — Mayan EDMS is purpose-built for these scenarios. It is less suitable for managing creative media assets like photos and videos.

Why Self-Host Your DAM Platform?

Storage cost control: Commercial DAM platforms charge per GB of storage and per user. A self-hosted DAM on commodity storage hardware or a low-cost S3-compatible backend can handle terabytes of assets at a fraction of the cost.

Custom metadata schemas: Every organization has unique metadata requirements. Self-hosted platforms let you define custom fields, taxonomies, and metadata extraction rules without being limited by a vendor’s data model.

Integration flexibility: Self-hosted DAMs expose full APIs and database access, enabling deep integration with your existing CMS, e-commerce platform, marketing automation tools, and internal systems.

Data sovereignty: For organizations in regulated industries, keeping all digital assets on-premise or in a chosen cloud region ensures compliance with data residency requirements.

FAQ

Can ResourceSpace handle video files?

Yes, ResourceSpace supports video files including MP4, AVI, MOV, and WMV. It generates video thumbnails and previews using FFmpeg. However, it does not include video transcoding or streaming capabilities — it stores and serves the original files. For advanced video management, consider integrating with a dedicated video platform.

Does Pimcore require a commercial license?

Pimcore Community Edition is fully open-source under the GPL v3 license and free to use. Pimcore also offers a commercial Enterprise Edition with additional features like advanced workflow management, custom report builder, and professional support. For most DAM use cases, the Community Edition provides all necessary functionality.

Can Mayan EDMS replace a traditional DAM?

Mayan EDMS is optimized for document management rather than creative asset management. It excels at OCR, document workflows, and records management but lacks features common in DAM systems like image editing, color profile management, and creative preview tools. For organizations that primarily manage documents, contracts, and records, Mayan EDMS is an excellent choice. For photo and video libraries, ResourceSpace or Pimcore would be better suited.

How do these platforms handle large file uploads?

All three platforms support large file uploads through chunked transfer or direct-to-storage uploads. ResourceSpace and Pimcore use PHP’s standard upload handling with configurable size limits. Mayan EDMS supports streaming uploads directly to the S3-compatible storage backend, bypassing the application server for very large files. For multi-gigabyte files, configuring a reverse proxy (Nginx or Caddy) with appropriate timeout and body size settings is recommended.

Do these platforms support SSO and LDAP authentication?

Yes, all three platforms support external authentication. ResourceSpace offers LDAP and SAML integration. Pimcore supports LDAP, SAML, and OAuth2 through Symfony Security. Mayan EDMS supports LDAP and can integrate with OAuth2/OIDC providers through Django authentication backends. All three can integrate with self-hosted identity providers like Keycloak or Authentik.

What is the minimum hardware requirement?

ResourceSpace runs comfortably on 2 GB RAM with a small database. Pimcore requires at least 4 GB RAM due to its comprehensive feature set and Symfony framework overhead. Mayan EDMS requires 4 GB RAM minimum (8 GB recommended) because it runs multiple Celery workers for OCR and background processing, plus PostgreSQL and Redis.
