LibreMoodboards vs Mattoboard

LibreMoodboards is a free, open-source Windows moodboard application built with Electron. It accepts images, GIFs, videos, and audio such as music or sound effects, and lets users add text notes and bookmarks. Files can be placed freely instead of following a fixed organization scheme. The app has no accounts or cloud service; the project says content remains local. It has no subscriptions, microtransactions, or paywalls. LibreMoodboards is released under GPLv3, with modifications and forks required to remain open source. The latest listed release is v1.0.0, described as the initial release. That release includes a portable Windows executable and source code; the executable runs without installation. The README also documents npm install and npm run build commands for building from source. The project welcomes issues and pull requests and suggests discussing major changes in an issue first.

Mattoboard is a web platform for creating 3D moodboards and virtually sampling materials from its library and brand partners. The library includes more than 50,000 real-world products and materials. Design Stream can create editorial-style interior images from a brief, plan, or photo and match real products; prompts and reference images can also guide a 3D material board. Board tools include drag-and-drop material swaps, Deep Render images, background removal, and PDF material sheets with product links. PRO Teams adds shared boards, projects, collections, virtual material libraries, and project folders with details and deadlines. Collaboration is real-time, with guest access and presentation mode; exports are available as PNG, WEBP, and PDF. The Free plan includes 5 Matto AI credits, up to 10 images per board, up to 10 uploaded materials and paints, 4 Deep Renders per month, and limited templates and accessories. A 7-day trial is available. Pro, Teams, and Enterprise options are listed, but prices are not provided; Teams and Enterprise direct buyers to contact sales.
