Self-hosted media processing that resizes, crops and converts images and video through URL parameters, for teams replacing a hosted delivery service.
Openinary covers the media pipeline a product ends up needing anyway, from upload and storage through resizing, format conversion and delivery. It is self-hosted, so both the assets and the cost of transforming them stay on infrastructure you picked.
Transformations are expressed in the URL. A path segment carries width, height, crop mode, gravity, quality and target format, and the result is generated on request and cached. Video takes the same syntax, with start and end offsets for clipping and a thumbnail pulled from a given second.
The pieces around the transformer come included rather than assembled.
- Storage: an S3-compatible layer for AWS S3, Cloudflare R2 or any compatible endpoint, configured by environment variables.
- Optimization: WebP, AVIF and modern codecs applied automatically.
- REST API: programmatic access alongside the URL based transformations.
- Admin dashboard: asset management, first-run setup and API key generation.
- Installer: a create command scaffolds the project, writes a compose file and an environment file, then starts the containers.
- One-click deploys: templates for Railway, Coolify and Dokploy.
Running it needs Docker 20 or later and Node.js 20 or later, and installing the CLI globally adds start, stop and upgrade commands. The repository is AGPL-3.0 apart from the managed cloud service, which is source available, and the marketing site, which is MIT. The project is pre-1.0 and does not yet promise backward compatibility.
