LibreMoodboards vs Soleil Clusters

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.

Soleil Clusters is a visual workspace for film, photo, design, and brand teams to collect references, storyboards, shot lists, scripts, and schedules. Shared boards, called clusters, use an infinite canvas with live cursors, comments, and presence. Built-in documents let users write briefs beside the canvas, while tags gather references and a relationship graph connects cards and boards. Boards are private by default; users can invite collaborators or share a view-only public link that does not require an account to open. Images, video, audio, and PDFs become cards with viewers or players, while other files become downloadable cards. Clusters offers a REST API and an MCP server, with OAuth or personal access tokens for integrations. The free plan includes 50 cards, unlimited clusters and collaborators, and standard media only. Creator costs $25.00 per month, or $20/mo billed annually ($240/yr), and includes unlimited cards, any file type, no per-file size limits, and 100GB drive. It works in browsers, as an installable PWA, and through native iOS and Android apps.
