Trello vs Microsoft Planner: Flexible Kanban vs Task Boards Inside Microsoft 365

Choosing between Trello and Microsoft Planner usually comes down to one question: does your team already live in Microsoft 365? Planner is included with most Microsoft 365 business and enterprise subscriptions, opens as a tab inside Teams, and syncs with Outlook and To Do - which makes it the path of least resistance for a Microsoft shop. Trello is the original kanban board: standalone, flexible, easy to love, with a generous free plan, Butler automation, and an ecosystem of Power-Ups that connects it to almost anything. Both are card-and-board tools at heart, so the decision hinges on ecosystem fit, how much planning depth you need, and what you are willing to pay for it.

This comparison covers ease of use, task management, views and Gantt charts, collaboration and ecosystem, automation and AI, and pricing so you can pick with confidence.

Choose Trello if…

• You want a standalone board that works for anyone, with no Microsoft account or admin involved
• You need automation and integrations - Butler rules and unlimited Power-Ups even on the free plan
• Your team is small and budget-conscious - Trello Free covers 10 boards and 10 collaborators

Choose Microsoft Planner if…

• Your organization runs on Microsoft 365 and you want boards inside Teams, Outlook, and To Do at no extra cost
• You need Gantt, dependencies, and sprints - Planner Plan 1 includes them for $10/user/month
• IT wants everything under one tenant with Microsoft security, compliance, and sensitivity labels

#Quick Comparison

#Ease of Use and Interface

Trello is the tool people learn without a tutorial. A board has lists, lists have cards, and cards open into a detail panel with checklists, labels, due dates, members, and attachments. The 2025 redesign added an Inbox for capturing to-dos from email, Slack, and Teams before they land on a board, and a personal Planner view that pairs your cards with your calendar. That last feature shares a name with Microsoft Planner, which causes confusion in search results but is a personal scheduling view, not a competitor product.

Microsoft Planner is nearly as approachable, especially in its newer unified app that merged Planner, To Do, and Project for the web. A plan has buckets and tasks; tasks carry checklists, labels, priority, dates, and attachments from OneDrive or SharePoint. The interface is clean and familiar to anyone who uses Microsoft 365, and it lives as a tab in Teams channels. The catch is that Planner assumes a Microsoft tenant: plans belong to Microsoft 365 Groups, permissions follow the group, and there is no way to invite someone who does not have an account in your organization.

Verdict: Trello has the edge here because it is simpler to start and open to anyone, while Planner is easy only if you already live inside Microsoft 365.

#Task and Project Management

Trello's card model is flexible but shallow by design. Cards get checklists, labels, due dates, members, attachments, and (from Standard) custom fields and advanced checklists with assignees and dates per item. Card mirroring on Standard lets the same card appear on several boards. What Trello lacks natively is structure across boards: no dependencies, no subtask hierarchy beyond checklists, and no roll-up of progress across projects without a Power-Up or the Premium Dashboard view.

Planner's basic plans cover the same ground - buckets, checklists, labels, priority, progress states - and then Plan 1 opens a second tier of planning. Premium plans add task dependencies (finish-to-start), backlogs and sprints for agile teams, project goals you can link tasks to, premium templates, and custom fields. Plan 3 adds advanced dependencies with lead and lag, baselines, and critical path analysis borrowed from Microsoft Project. Task chat with mentions is rolling out to basic plans in 2026 and replaces the old comments, and reusable plan templates let organizations standardize onboarding or campaign plans.

Verdict: Microsoft Planner has the edge here because Plan 1 brings dependencies, sprints, and goals that Trello can only approximate with Power-Ups.

#Views and Gantt Charts

Trello Free and Standard give you the board view plus Inbox and personal planning. The views most teams eventually want - Calendar, Timeline, Table, Dashboard, and Map - are Premium at $10/user/month, and workspace-level views that pull cards from many boards are also Premium. The Timeline is a clean date-based layout, but without native dependencies it is a schedule picture rather than a planning engine.

Planner's basic plans include Board, Grid (list), Schedule (calendar), and Charts views for every plan. Plan 1 adds Timeline (a genuine Gantt with dependency lines), Calendar, and People views, and lets you view portfolios that roll up multiple plans. Plan 3 lets you create portfolios and adds the Project desktop client for heavy scheduling. For the same $10 per user that buys Trello Premium's views, Planner Plan 1 delivers a Gantt that understands dependencies and sprints.

Verdict: Microsoft Planner has the edge here because its calendar and charts are included on every plan and its Plan 1 Gantt handles dependencies, while Trello locks all non-board views behind Premium.

#Collaboration and Ecosystem

This is where the two tools are shaped by different worlds. Planner's collaboration is Microsoft 365 itself: a plan is a tab in a Teams channel, task assignments flow to Outlook and To Do, files live in SharePoint, meeting notes from Teams can become tasks, and a channel agent can create and update tasks from conversation. Sensitivity labels and Information Barriers apply to task content, which regulated industries care about. The price of that depth is that the ecosystem ends at the tenant boundary.

Trello collaborates with the wider internet. Anyone can be invited by email, boards can be public, and Power-Ups connect Slack, Google Drive, Jira, GitHub, Figma, Salesforce, and hundreds more - unlimited per board even on Free. Trello has a Microsoft Teams app too, so a Microsoft shop can use Trello inside Teams, but the integration is a window into Trello rather than the native experience Planner offers. Atlassian's ownership means Trello also links tightly with Jira and Confluence.

Verdict: Microsoft Planner has the edge for teams inside Microsoft 365, and Trello has the edge for everyone else - the ecosystem you already use decides this one.

#Automation and AI

Trello's Butler automation is one of the best in its class: rules, card and board buttons, calendar and due-date commands, all built with a no-code trigger-and-action editor. Free includes 250 Workspace command runs a month, Standard 1,000, and Premium unlimited. Atlassian Intelligence arrives on Standard and above with card summaries, list organization, and AI-generated boards. Atlassian's Rovo assistant reaches Trello through the wider Atlassian stack.

Planner's automation lives in Power Automate, which is more powerful and less approachable - a flow builder rather than a rule inside the board, though business process flows are available on premium plans. The AI story is bigger: the Planner Agent (formerly Project Manager agent) turns goals into structured task lists, generates status reports, summarizes risks and blockers, and works in both basic and premium plans - but it requires a Microsoft 365 Copilot license at $30 per user per month on top of whatever Planner plan you hold. That is the most capable AI of the two and also the most expensive to switch on.

Verdict: Trello has the edge on automation you can set up in a minute, while Planner's Copilot-powered agent is the stronger AI if your organization already pays for Microsoft 365 Copilot.

#Pricing and Value

Trello Free is one of the most generous in the category: unlimited cards, up to 10 boards and 10 collaborators per Workspace, unlimited Power-Ups, Inbox, 250 automation runs a month, and 10 MB per file. Standard is $5/user/month billed annually ($6 monthly) for unlimited boards, custom fields, advanced checklists, card mirroring, AI features, and 1,000 automation runs. Premium is $10/user/month annually ($12.50 monthly) for the Calendar, Timeline, Table, Dashboard, and Map views, workspace views, and unlimited automation. Enterprise is $17.50/user/month annually.

Microsoft Planner has no standalone free plan. Basic Planner is included with most Microsoft 365 business and enterprise subscriptions, so for a team already paying for Microsoft 365 the marginal cost is zero. Planner Plan 1 is $10 per user per month paid yearly and adds premium plans with Timeline (Gantt), dependencies, sprints, goals, and People view. Planner and Project Plan 3 is $30 per user per month paid yearly for portfolios, advanced dependencies, baselines, critical path, and the Project desktop client. Plan 5 exists above that for enterprise portfolio and resource management. Add Microsoft 365 Copilot at $30 per user per month if you want the Planner Agent.

The value calculation flips on ecosystem. A Microsoft 365 team gets a solid board tool for free and a real Gantt for $10, which beats Trello's $10 Premium for planning depth. A team without Microsoft 365 gets more from Trello Free than Planner can offer at any price, because Planner is not sold without a Microsoft seat.

Verdict: Microsoft Planner has the edge on value for Microsoft 365 customers because the basic tier is already paid for, while Trello has the edge for everyone else with a free plan Planner cannot match.

#Which Tool Is Right for You?

Choose Trello if you need:

• A board that anyone can join in seconds - clients, contractors, volunteers - with no Microsoft account
• Butler automation and Power-Ups on the free plan, and a paid tier that starts at $5
• A tool that connects to Slack, Google Workspace, Jira, and the rest of a non-Microsoft stack

Choose Microsoft Planner if you need:

• Boards inside Teams with tasks that flow to Outlook and To Do, at no cost beyond Microsoft 365
• Gantt charts, dependencies, sprints, and goals for $10 per user on Plan 1
• Microsoft's compliance controls - sensitivity labels, Information Barriers, one admin console

For a 5-person startup on Google Workspace, Trello Free is the obvious choice and Planner is not even available. For a 50-person company on Microsoft 365 Business Standard, Planner is free today and Plan 1 is a cheaper route to Gantt charts than Trello Premium. For a marketing team or agency collaborating with outside clients, Trello's open invitations and public boards matter more than Planner's tenant-bound model.

#Frequently Asked Questions

#Conclusion

Trello and Microsoft Planner are both easy kanban tools that go in different directions. Planner is the better choice for organizations on Microsoft 365: it is already paid for, it is native to Teams and Outlook, and Plan 1 turns it into a real planning tool with Gantt charts, dependencies, and sprints for $10 per user. Trello is the better choice for small teams and remote teams outside the Microsoft world, where its free plan, Butler automation, and open collaboration are hard to beat. If you want every view and dependencies on the free plan, open collaboration, and AI without a Copilot license, try t0ggles free.
