6 online whiteboards worth trying

Free-plan details can change; these limits are a useful starting point rather than a guarantee of every current account's entitlements.
My recommendation
For a team that needs one tool for everything: Start with Miro.
For an easy, creative brainstorming session: Try FigJam.
For workshops with structured exercises: Choose Mural.
For a free, straightforward diagramming tool: Try Excalidraw.
For visual planning that feeds into presentations: Choose Canva Whiteboards.
If your priority is keeping costs at zero for a larger team, compare the number of editable boards, collaborator limits, and whether guests need accounts before selecting a platform.
Yes — there are several excellent browser-based whiteboards with free plans that support team brainstorming, sticky-note collaboration, flowcharts, process mapping, and visual workflow creation. The main difference is how much you can do for free: some limit the number of editable boards, while others are better for unlimited diagramming or lightweight collaboration.
Best free online whiteboards to consider
1. Miro
(Best all-rounder)
A versatile collaborative canvas for brainstorming, mind maps, flowcharts, retrospectives, customer journeys, and process workflows.
Free plan: Up to 3 editable boards, with unlimited team members.
Best for: Teams that want brainstorming and structured workflow mapping in one place.
Watch out for: All team members can access the free team's boards; private boards require a paid plan.
Plan details are based on the vendors' published information.
My recommendation
For a general-purpose team workspace: Start with Miro. It combines collaborative brainstorming and visual workflow creation, although its three-board limit matters.
For design and product teams: Choose FigJam if your team already works in Figma.
For the most diagram-focused free option: Try diagrams.net.
For a simple, free collaborative canvas: Try Excalidraw. Its browser editor supports real-time collaboration, sketching, and diagrams.
One important distinction: if you need multiple people to brainstorm together and then turn those ideas into repeatable process maps, Miro is my first choice. If you mainly need to create detailed flowcharts without paying, diagrams.net is a strong starting point.
What kind of workflow are you looking to create? For example, business processes and decision trees, software or product workflows, or project planning with tasks and swimlanes? I can narrow the options to the best free tools for that specific use case.
