Self-hostable DAM platform for managing images, video, documents, and audio with metadata search, approval workflows, and open API integrations.

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:
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.
