## Quick answer

There is no single best free classroom whiteboard; the right one depends on whether students can be asked to sign in. Cnvs.app is the top pick when they cannot, because a board opens from a link with no account for anyone, while Canva, FigJam and Miro win on features once your school verifies for their free education plans.

## Key takeaways

- Google Jamboard was discontinued on December 31, 2024, and Google pointed education users to FigJam, Lucidspark and Miro; the free options here are the practical replacements.
- The real dividing line for classrooms is not features but student sign-in, since account-based tools need verification, invitations or school email for every learner.
- Cnvs.app ranks #1 for zero-friction lessons: no account for teacher or students, a shareable link, drawing, sticky notes, pasted images and Markdown, and an optional access code.
- Canva Education is free for K-12 teachers and students only (not higher education), and students must be invited by their teacher.
- Miro's Educator plan is free with 100 team members, while the Student plan gives 10 members and expires after 2 years (Miro Education page, checked 2026-09-29).
- Padlet's free plan is limited to 3 padlets, and the Classroom plan for student accounts is priced at $199 per year according to aggregator listings.

## FAQ

### What is the best free online whiteboard for teachers that needs no student accounts?

Cnvs.app is the strongest fit. A teacher opens a board, shares the link and students edit live with no account, and the tool is free with no paid tier. Excalidraw also needs no signup for its core app, though it is more minimal.

### What replaced Google Jamboard?

Google discontinued Jamboard on December 31, 2024 and recommended FigJam, Lucidspark and Miro. FigJam and Miro both have free education routes, and Cnvs.app and Excalidraw are no-account alternatives.

### Is Canva free for teachers?

Canva for Education is free for K-12 teachers, students and qualified school districts, but it is not currently available to higher-education teachers or institutions. Students must be invited by their teacher.

### Is Miro free for teachers?

Yes. According to Miro's Education page, the Educator plan is free with no expiry and 100 team members, while the Student plan offers 10 team members and 2 years of access.

### Are no-account whiteboards safe for schools?

Not needing accounts avoids collecting student credentials, but it does not replace a school privacy review. Anyone with a board link can join unless an access code is set, so use the access-code option where available and avoid sharing sensitive student information on any open board.

## How we evaluated

We ranked each tool on whether students need an account, the real free limit or education-plan eligibility as stated on the vendor's own pages on 2026-09-29, ease of starting a live lesson, and depth of classroom features. Where a figure came only from aggregator summaries, such as Padlet's paid prices, we say so and recommend confirming on the vendor site. Google's Jamboard end date is corroborated by university IT notices and multiple reviews. Free tiers and education eligibility change often, so re-check before rolling a tool out across a class.

- Student account requirement and sign-in friction
- Verified free-tier limits and education-plan eligibility
- Depth of collaboration features for live and asynchronous lessons
