Great ideas rarely arrive in a straight line. Whether you are brainstorming with a remote team, planning a lesson, mapping a project, or sketching a product idea, a digital whiteboard gives everyone one canvas — with sticky notes, drawings, diagrams, and images — that you can save, share, and revisit anytime.
In this guide, we compare the best free whiteboard software in 2026 for teams, teachers, students, and solo creators, all legal and free to start.
What to Look for in a Free Whiteboard
A good free whiteboard should offer an infinite canvas, sticky notes, shapes and connectors, real-time collaboration, and easy sharing via link. Check the free plan's limits carefully: some tools cap the number of boards, collaborators, or objects per board. The tools below all offer genuinely usable free tiers.
1. Miro (Free Plan)
Miro is the most popular online whiteboard, and its free plan includes three editable boards with unlimited team members, templates for brainstorming, mind maps, flowcharts, and retrospectives, plus sticky notes, comments, and integrations with tools like Slack and Google Drive.
Best for: teams that want the most polished, template-rich whiteboard experience.
Downside: the free plan limits you to three editable boards, so archive or delete old boards to stay within the limit.
2. Excalidraw
Excalidraw is a free, open-source whiteboard with a charming hand-drawn style. It runs entirely in your browser, needs no account for basic use, and lets you collaborate live by sharing a link. You can also self-host it on your own server or computer.
Best for: quick sketches, architecture diagrams, and privacy-conscious users.
Downside: it has fewer templates and business integrations than Miro.
3. Microsoft Whiteboard
Microsoft Whiteboard is completely free with a Microsoft account and works on Windows, the web, iOS, and Android. It offers an infinite canvas, sticky notes, ink, and real-time collaboration through Teams and OneDrive.
Best for: Windows users, schools, and Teams-based teams.
Downside: its template library is smaller than Miro's, and some features need a Microsoft 365 account.
4. Canva Whiteboards
Canva's free plan includes online whiteboards with sticky notes, shapes, diagrams, and a huge library of templates. If you already design in Canva, adding a brainstorm board to your project is easy and free.
Best for: creators and small teams who already use Canva.
Downside: advanced whiteboard features like voting and timers are limited on the free plan.
5. OpenBoard
OpenBoard is a free, open-source interactive whiteboard originally built for schools. It works offline on Windows, Mac, and Linux, and it supports pen input, PDF annotation, and interactive widgets for lessons.
Best for: teachers, classrooms, and offline use.
Downside: real-time online collaboration is not its strength — it shines in face-to-face teaching.
6. Mural (Free Plan)
Mural is a polished collaboration whiteboard used by design teams worldwide. Its free plan offers a limited number of boards and members, but still includes sticky notes, templates, voting, and timers for structured workshops.
Best for: facilitated workshops and design thinking sessions.
Downside: the free plan caps the number of boards and members.
7. Google Jamboard Alternative: FigJam (Free Starter)
Google Jamboard was discontinued in 2024, so former Jamboard users need a new home. FigJam, from the makers of Figma, is the natural replacement: an infinite canvas with sticky notes, shapes, connectors, and a free starter plan for small teams.
Best for: ex-Jamboard users and design-adjacent teams.
Downside: the free plan limits editable boards to three.
How to Run a Better Brainstorm
Set a clear question before you open the board, give everyone five silent minutes to add sticky notes, then group similar ideas together and vote on the best. A timer and a simple voting round turn a messy board into a decision — most of the tools above include both features for free.
Whiteboard vs. Mind Map vs. Notes App
It is easy to confuse these three tools. A whiteboard is best for free-form, collaborative thinking — sticky notes you can move, group, and vote on together. A mind map is better for a single branching idea with a clear hierarchy, and many whiteboards include mind-map templates if you need both. A notes app is best for linear writing and reference. If your work involves group discussion, start with a whiteboard; if it is solo planning, a mind map or notes app may be enough. The good news is that several tools on this list, including Miro and Canva, cover all three styles in one free plan.
Frequently Asked Questions
Are free whiteboards really free for teams?
Yes, for small teams. Most free plans allow unlimited viewers and collaborators on a limited number of boards. Only larger teams that need many active boards need a paid plan.
Can I use a whiteboard without an account?
Excalidraw works without an account for basic sketching, and most others let guests join a shared board without signing up. Creating and saving your own boards usually requires a free account.
Which whiteboard is best for teaching?
Microsoft Whiteboard and OpenBoard are both strong for classrooms — Whiteboard for online lessons and Teams, OpenBoard for offline, pen-based teaching on a classroom display.
What happened to Google Jamboard?
Google shut Jamboard down at the end of 2024. FigJam, Miro, and Microsoft Whiteboard are the best free migration paths, and all can import or recreate Jamboard-style boards.
Conclusion
You do not need a paid subscription to brainstorm well. Start with Miro if you want templates and polish, Excalidraw if you want speed and privacy, or Microsoft Whiteboard if you live in the Microsoft ecosystem. Open any of them, invite your team, and turn your next idea into something visible.
