Upload, transform, and deliver images and videos via a REST API and URL parameters, using your own S3-compatible storage. Cloudinary-compatible syntax, no vendor lock-in.

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.
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.
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.
Messaging Infrastructure for Developers. One API for SMS, WhatsApp, and RCS across 190+ countries.
