cnvs.app is a deliberately minimal Miro alternative: open a URL, share it with anyone, draw and write together in real time. No accounts, no team setup, no paywall when the team grows. Built-in Mermaid diagrams and a public MCP endpoint so Claude or GPT can collaborate on the same live board.

You're running an organised workshop, retrospective or PI planning session for a team that already pays Miro. You need templates, sticky-note voting, timers, breakout rooms, Jira sync, SSO, audit logs. The price-per-seat is acceptable because the facilitation features pay for themselves.
You're on a call with one or three people and want to sketch something on a shared surface in 5 seconds. You don't want anyone to have to sign up, log in, or wait for a corporate SSO redirect. You don't need templates — you just need a blank canvas and a link to share.
cnvs.app ships a public Model Context Protocol endpoint at https://cnvs.app/mcp. Add it once to Claude Desktop / Claude Code / Cline / Goose and the AI can read and edit any board you point it at — live, alongside human collaborators. Miro has Miro AI, but it's a paid feature locked inside Miro's own clients; there's no equivalent open endpoint that any MCP-capable agent can talk to.
Free forever, not freemium. The core collaborative whiteboard — unlimited boards, real-time sync, image and URL paste, PDF export, dark mode, mobile, MCP — is included at $0. There is no upsell page; there isn't even a signup page.
No. Templates are out of scope by design — they add UI weight that gets in the way of the "open a URL and draw" flow. If your work needs templates, Miro is the better pick.
Not directly. Miro's export formats are JSON/CSV/PDF/image; cnvs.app accepts pasted images and URLs. You can export a Miro board to PNG and paste it onto cnvs.app as a background reference.
