What it does
cnvs.app offers a minimal shared canvas for real-time drawing, text, pasted images, and links, with an option to switch a board into a lightweight Kanban mode. The official page says no signup is needed and lists unlimited boards and collaborators at no charge. Boards are purged after 30 days without activity, and the service does not offer self-hosting.
cnvs.app is a quick way to open a board for a small group without account setup or a paid plan. The canvas supports drawing, text, pasted images, and links, while the lightweight Kanban mode gives teams a simple way to arrange work. The official page states that boards are free, unlimited, and shared with unlimited collaborators, but inactive boards are deleted after 30 days. The vendor also says self-hosting is not available, so this is best for ephemeral collaboration rather than long-term private board archives.
