Open Source Acquia DAM Alternatives

Openinary is a self-hostable media platform built as an open alternative to Cloudinary. It handles image and video uploads, on-the-fly transformations, and edge delivery, all from infrastructure you control. Teams tired of Cloudinary's pricing or vendor lock-in are the obvious audience, but it's equally useful for any project that needs media handling without handing over storage to a third party.

The core idea is simple: point Openinary at your existing S3-compatible storage and start uploading. No migration required.

• URL-based transformations let you resize, crop, convert formats, adjust quality, and transcode video by changing URL parameters. No code changes needed if you're already using Cloudinary's syntax.
• S3-compatible storage works with AWS S3, Cloudflare R2, MinIO, Google Cloud Storage, or any compatible provider.
• REST API uploads handle programmatic media ingestion, with SDKs available for Node.js, Next.js, Remix, Python, Go, and Rust.
• Edge delivery optimizes content for global performance without requiring a separate CDN setup.
• Media browser UI is included alongside the upload API, so you're not managing files blind.

The self-hosted version is free under the AGPL 3.0 license with no feature restrictions. Infrastructure costs are your only expense, typically a few dollars a month when paired with something like Cloudflare R2. A managed cloud option is also available in public alpha, with a free tier covering 1 GB of storage, 500 transformations, 15 minutes of video processing, and 25,000 CDN requests per month, no credit card required.

For teams migrating from Cloudinary specifically, the compatible transformation syntax means existing URLs and integrations can carry over without rewriting logic.

ResourceSpace is a digital asset management platform built for organisations that need a governed, central home for their files. Museums, charities, universities, NGOs, and brand teams use it to store, find, and distribute images, video, documents, audio, and guidelines without relying on shared drives or siloed folders.

The core strength is metadata. Rich, structured tagging means teams can find exactly what they need through search rather than browsing folder trees. Assets carry statuses like Active, Pending Review, or Archived, so everyone knows what's approved and what isn't.

Key capabilities include:

• Approval workflows that route assets through review before they're accessible or shareable
• Granular permissions so different teams, partners, or public users only see what they're supposed to
• Secure share links and public portals for distributing assets to external collaborators without giving them full system access
• User submission queues letting contributors upload assets that go through moderation before entering the library
• Built-in analytics showing download activity, usage frequency, and rights exposure
• Open API and pre-built integrations with collections management systems, CMS platforms, and social tools
• Enterprise SSO and MFA for organisations with strict identity requirements
• Privacy-focused AI for asset processing that doesn't feed third-party training models

For photo and video-heavy teams, automated format conversions reduce manual work when distributing assets across different channels or formats.

Compared to proprietary alternatives like Acquia DAM, ResourceSpace's source code is publicly available, so organisations can audit it, extend it, and avoid vendor lock-in. It's employee-owned, GDPR-compliant by design, and backed by a dedicated support team rather than a generic helpdesk. Over 500 organisations across 40+ countries rely on it, with a 4.9/5 customer rating across reliability and ease of use.

Phrasea is a digital asset management platform built for organizations that need serious control over their media libraries. It's designed for communication teams, marketing departments, and creative studios that manage large volumes of images, videos, documents, and other digital files across multiple users and workflows.

At its core, Phrasea is built around a powerful search engine backed by Elasticsearch. You can find any asset in seconds using autocomplete, faceted filters, and full-text metadata search across multiple languages. Assets are organized hierarchically, versioned, and available through fine-grained access controls that let you define exactly who can see, download, or share what, down to individual users, groups, and collections.

Key capabilities include:

• AI-assisted indexing: Automatic text detection and keyword suggestions reduce manual tagging work significantly.
• Workflow engine: Built-in tools to automate asset production and route files through approval or processing steps.
• Renditions and versioning: Generate and store multiple versions of an asset without losing the original.
• SSO and MFA: Enterprise-grade authentication out of the box.
• API-first architecture: Every function is accessible via API, with native connectors to PIM systems and other business tools.
• Deployment flexibility: Available as SaaS, on-premise, or hybrid, with Docker and Kubernetes support for scalable infrastructure.

For business DAM use cases, Phrasea connects with PIM platforms to keep product image databases consistent and regulation-compliant. Creative teams get workflow automation and collaboration tools. IT departments get CDN support, scalability, and full data ownership since the source code is open and self-hostable.

Compared to proprietary platforms like Acquia DAM, Phrasea gives you complete infrastructure independence. Nothing is locked behind a vendor. The platform has been developed over 30 years of client project experience, which shows in the depth of its permissions model and its multilingual indexing support.
