What is Lumio?
Lumio is an independent, open-source graphic design editor for creating designs from templates or a blank canvas. Its editor supports text, shapes, images, layers and multi-page layouts, with a brand kit for saved colors, a font and a logo. Designs can be exported as images or multi-page PDFs, or transferred between Lumio servers as editable project files.
The application supports personal designs, team workspaces, viewer and editor roles, and view-only sharing with comments. Self-hosting requires a Next.js server application and PostgreSQL; static hosting alone is insufficient. Optional AI generation and background removal require external provider keys. Collaboration synchronizes saved changes when an editor is idle, while conflicting unsaved changes require reloading the latest version.
The README names version v0.1.0 as the latest release. The dashboard offers 12 size presets and 20 editable templates, and the editor bundles 10 fonts. Uploads accept PNG, JPEG, WebP and GIF files up to 10 MB, stored in PostgreSQL, and designs autosave about a second after each change.
Key capabilities
- Canvas editing Build multi-page designs with editable text, shapes, images, backgrounds, layers, alignment tools and undo history.
- Production workflows Generate graphics from CSV-driven text placeholders, import supported SVG elements as editable layers and review advisory design health warnings.
- Exports and portability Export PNG, JPG, SVG and multi-page PDF files, or transfer editable projects with their uploaded images between Lumio servers.
- Design management Organize designs into folders and favorites, recover trashed items, and restore automatic checkpoints or named versions.
- Sharing and workspaces Assign editor or viewer access, share read-only designs with comments and let recipients make a copy.
- Optional provider features Generate copy, layout suggestions and images with an OpenAI key, or remove image backgrounds with a remove.bg key.
Where Lumio fits
Lumio fits workflows that need reusable graphic templates, personalized batches of graphics and shared team design workspaces. Its portable project format also supports moving editable designs between separately hosted instances.
Before deployment, operators should verify database connectivity, backups, HTTPS configuration and email recovery settings. Vercel deployments require particular attention to upload and response limits. Teams should test concurrent editing behavior, review generated layouts visually and assess external provider billing before enabling AI or background removal.
