Kanvaz vs LibreMoodboards

Kanvaz is an offline reference board for VFX and 3D artists, as well as anyone who collects and connects visual material. Its infinite canvas can hold 3D models, images, GIFs, video, audio, notes, colors, URLs and file pointers. Supported 3D models can be orbited live, viewed in different shading modes and played with animation; previewing .blend files requires Blender. Seven kinds of typed relationships link references, which users can explore as a graph in Map View. A single card can appear on multiple boards, with edits carried across those appearances. An optional MCP Bridge lets Claude Desktop or Claude Code read and change the active board over local IPC, and those changes enter undo history. Kanvaz supports plugins for card types, commands, themes and other features; its maker says creators can sell plugins without a marketplace cut. Boards are stored locally in .kanvaz ZIP containers with embedded assets and SHA-256 integrity hashes. The maker says there are no accounts, telemetry or cloud storage, and network requests are user initiated. Kanvaz is free forever, MIT licensed and available for Linux, macOS and Windows.

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.
