Trello is a mature kanban tool with Power-Ups, automation and several board views, but it is built around accounts and Workspaces: its free plan is capped at 10 open boards and 10 collaborators per Workspace, and the rest sits behind per-user plans. cnvs.app gives you a real-time kanban / to-do board you can open and share in seconds with no signup, no per-seat pricing and an MCP endpoint that needs no account. The same board can flip to an infinite drawing canvas.

Trello facts are taken only from Trello's and Atlassian's own pages, checked 24 October 2026: trello.com/pricing, which plan is best, free Workspace collaborator limit, automation quotas, Trello MCP. Plans and limits change, so check them before you decide.
You want a full work-management workspace: automation, Power-Ups, Calendar and Timeline views, integrations and mobile apps, and you are fine with accounts and per-user plans as your team grows.
You need more than 10 open boards or 10 collaborators per Workspace, higher automation quotas, Custom Fields, or the Premium views and admin controls, and you are OK paying per user for them.
You want a shared kanban board in seconds with no signup and no per-seat cost, real-time sync, an AI agent that can join over MCP without an account, and an infinite drawing canvas next to the task list. Honest limits: anyone with the board ID can edit unless you PIN-lock it, no automation or Power-Ups, and boards are deleted after up to 30 days of inactivity.
Trello now has an official Model Context Protocol server (https://mcp.trello.com/v1). It works on any Trello plan with OAuth sign-in, lets you choose which Workspaces to authorise, and can archive but not permanently delete cards and lists. cnvs.app ships a public MCP endpoint at https://cnvs.app/mcp that needs no account: add it once to Claude Desktop, Claude Code, Cline or Goose and the AI can read and edit any kanban board you point it at, creating cards, setting priorities and assignees and moving them across columns, live and alongside humans. It also subscribes to cnvs://board/{id}/tasks.json to react when people move cards.

If you want a kanban board you can spin up and share in seconds with no signup and no per-seat pricing. cnvs.app gives you columns, cards with priority, due date, assignee and done state, and real-time sync for free, plus a public MCP endpoint that needs no account. Trello has a deeper feature set (Power-Ups, automation, Calendar, Timeline and other views) once you commit to accounts and a Workspace.
Trello's Free plan allows up to 10 collaborators and 10 open boards per Workspace, with unlimited cards and Power-Ups, 250 automation runs per month. A free Workspace over 10 collaborators becomes view-only. Standard ($5 per user per month billed annually) lifts the board and collaborator limits; Premium ($10 billed annually) adds the Calendar, Timeline, Table, Dashboard and Map views. cnvs.app has no accounts, so none of these limits apply.
Yes. Trello has an official MCP server at https://mcp.trello.com/v1 that works on any Trello plan. It signs in with OAuth, you choose which Workspaces to authorise on the consent screen, and it can archive but not permanently delete cards and lists. cnvs.app's MCP endpoint at https://cnvs.app/mcp needs no account, and the agent works on the same live board as the people.
Not for everyone. Trello offers Power-Ups, built-in automation, Calendar and Timeline views and mobile apps. cnvs.app is a lightweight, no-signup kanban board for fast shared task tracking, and it doubles as an infinite drawing canvas. Anyone with the board link can edit unless you PIN-lock it, and boards are deleted after up to 30 days of inactivity.
