Kanvaz vs Rayon

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.

Rayon is CAD software for interior designers and architects, focused on 2D architectural plans rather than 3D modeling. It combines drafting commands with BIM tools, and its AI features can find or generate assets, answer CAD questions, create architectural visuals, and turn images into vector sketches or wireframes. Teams can edit together in real time, comment, doodle, and share public links. The product includes more than 4,000 elements and more than 100 pre-built templates, with options to create custom libraries and templates. It imports DWG, DXF, PDF, and image files, capped at 25 MB, and exports PNG, PDF, DWG, and DXF. Rayon is available on the web and as Windows and macOS desktop apps. The Free plan costs nothing. Pro costs $21 a month billed monthly; Team costs $38 a month, per editor, billed monthly, and includes a 15-day free trial.
