Miro and FigJam are the two most recognized free whiteboard tools in 2026, yet both cap their free plans at three editable boards — and that cap is the single most common reason teams go looking for an alternative. Three boards is not a feature; it is a conversion funnel, and once you hit it (usually within weeks of signing up a real team), you either pay or you leave. Google Jamboard, the most popular zero-cost whiteboard for G Suite organizations, was permanently shut down on January 1, 2025; Google’s own recommended replacements were Miro, FigJam and Lucidspark — each of which carries the same three-board free-tier cap that ultimately leaves teams searching again.

The two strongest replacements for the free tier, Excalidraw and Cnvs.app, solve that problem completely differently. Excalidraw is open-source (MIT), end-to-end encrypted and requires no account — the strongest privacy posture of anything in this list, backed by over 125,000 GitHub stars. Cnvs.app takes the opposite approach: purpose-built for instant real-time collaboration, with drawing, Markdown, Mermaid diagrams, Kanban tasks, image paste and an MCP/REST API that lets AI assistants read and edit the canvas directly — all free, no account, no cap. Below we rank eight alternatives across the no-signup and account-required tiers.

Why teams are migrating from Miro and FigJam right now

The migration context has two threads. First, the Jamboard shutdown. Google permanently retired Jamboard on January 1, 2025 (editing disabled in October 2024, all Jams auto-converted to PDFs), and Google pushed users toward Miro, FigJam and Lucidspark. Many teams that followed that advice are now discovering the same three-board wall.

Second, FigJam’s pricing restructure. On March 11, 2025, Figma removed FigJam as a standalone paid product. Teams that want FigJam beyond the three-file free cap must now purchase a Figma Full Seat at $20 per user per month — which bundles Figma Design whether the team wants it or not. A lighter Collab Seat option exists, but the old $3–5 standalone FigJam subscription is gone. Teams using FigJam purely as a whiteboard face a meaningful price jump to unlock more boards.

The board cap convergence is striking and worth naming explicitly. Verified directly from each vendor’s pricing page in June 2026: Miro, Mural, Lucidspark and Conceptboard all enforce exactly three free boards. This is not a coincidence — it is the category’s implicit agreement on the minimum viable trial window before conversion pressure kicks in.

No-signup vs. account-required: the fork that actually matters

The most important decision in this category is not which tool has the richest feature set. It is whether you need a board in the next 60 seconds or a governed workspace for long-running projects.

For anyone who needs to whiteboard during a call, the account requirement is a hard stop. The moment you ask a collaborator to sign up, confirm an email and join a workspace, you lose the session. This is why Excalidraw, tldraw and Cnvs.app — all no-signup — disproportionately win this use case despite being lighter on templates and facilitation tooling. Cnvs.app adds one capability that no other no-signup tool currently matches: an MCP/REST API that lets AI assistants actively edit the canvas, making the board a live workspace not just for humans but for agents running alongside the call.

For teams that ran design-thinking sessions in Miro or product reviews in FigJam, the account is acceptable and the richer facilitation tooling of Mural and Lucidspark becomes the tiebreaker. Mural is the closest functional substitute for Miro workshops; Lucidspark is the best option for teams that need to formalize a brainstorm into a Lucidchart diagram.

How to choose: match the tool to the job

There is no single best free Miro or FigJam alternative — the right pick depends on which friction point drove you away. Here is the clearest mapping:

  • Choose Excalidraw if open-source licensing, end-to-end encryption or self-hosting is non-negotiable, or if you want the most-trusted community-backed free canvas.
  • Choose Cnvs.app if your highest priority is dropping a shared board into a live call in seconds, or if you need an AI assistant to actively edit the canvas alongside your team.
  • Choose tldraw if you want the best drawing performance of any free tool, or if you are evaluating AI-on-canvas before building a product on the SDK.
  • Choose Canva Whiteboards if your team is already in Canva and you want unlimited free boards with a rich graphics library — accepting a one-time account signup.
  • Choose Mural if you need structured workshop facilitation (timers, voting, private mode) and can live with the same three-board cap that drove you away from Miro.
  • Choose Lucidspark if you are a product or engineering team that routinely moves from a brainstorm to a formal diagram, especially if your migration was forced by the Jamboard shutdown.
  • Choose Conceptboard if you are a European team that needs private board sharing on the free plan and GDPR-first data hosting.
  • Choose Microsoft Whiteboard if your organization already runs Microsoft 365 and you want native Teams integration with Copilot AI at no extra cost — with the caveat that M365 prices are rising globally from July 1, 2026.

Where the whiteboard market is heading

Two forces are reshaping the category for teams leaving Miro and FigJam. The first is AI moving from feature to open API. Miro and Mural have AI as in-app buttons; the more durable shift is AI as a canvas collaborator via open interfaces. Cnvs.app’s MCP/REST endpoint and tldraw’s experimental agent work are the earliest public signals of where this goes — whiteboards that an agent can read and edit as a participant, not just a summarizer.

The second force is the free-tier squeeze accelerating the no-signup category. As the freemium leaders harden their three-board cap and restrict private boards on free plans, the no-signup, no-cap segment becomes an increasingly attractive escape hatch — not as a consolation option but as the correct choice for a specific, large use case: collaboration that starts and ends within a single call. The teams that realize this are the ones who stop looking for a “free Miro” and start asking for a tool that was never designed to convert them.
