AppFlowy vs Trello

AppFlowy is an open-source collaborative workspace that covers notes, wikis, databases and project boards, positioned as a privacy-focused alternative to Notion. It is built with Flutter for the interface and Rust for the core, so it ships as native apps for macOS, Windows, Linux, iOS and Android rather than a web wrapper, and its source code is published on GitHub under the AGPL license.

The core product combines rich documents with databases that can be viewed as a grid, kanban board or calendar, plus templates, offline mode and an AI assistant for writing, summarising and asking questions about your content. You can use AppFlowy Cloud as a hosted service with a free tier and paid per-user plans, or self-host the backend with Docker so that every page and database stays on your own servers.

AppFlowy fits developers, privacy-conscious teams and organisations with data residency rules who want a Notion-style experience without handing their content to a third party. It is less mature than Notion in integrations, templates, permissions and the polish of real-time collaboration, and its plugin ecosystem is small. Anytype is the other well-known open-source, local-first option; AFFiNE combines docs with whiteboards; Notion remains the safer choice when a broad integration ecosystem matters more than data ownership.

Trello is the kanban board tool created in 2011 at Fog Creek Software and acquired by Atlassian in 2017. It introduced millions of people to visual task management: boards hold lists, lists hold cards, and cards hold descriptions, checklists, due dates, labels, attachments, comments and members.

Power-Ups extend boards with calendars, voting, custom fields, and integrations with Slack, Google Drive, Jira and many other tools, while Butler automation moves cards, assigns people and sends notifications based on rules, buttons and schedules. Inbox and Planner features help individuals capture tasks and block time on a calendar. The free plan supports up to 10 collaborators per workspace with unlimited cards and a monthly automation allowance; Standard adds unlimited boards and custom fields, Premium adds calendar, timeline, table, map and dashboard views with unlimited automation, and Enterprise adds organization-wide permissions and SSO.

Trello fits individuals, small teams, freelancers, editorial calendars and simple workflows where a visual board is enough. It struggles once projects need dependencies, workload planning, portfolio reporting or many interconnected boards. Asana and monday.com are better for structured team project management, ClickUp packs more features at a low price, Jira is the natural upgrade for software teams already on Atlassian, and Notion suits teams that want boards inside a broader wiki.
