Miro open source alternatives

The one thesis that will save you a week

The core question is not “Which tool looks most like Miro?” It is “Do we need a collaborative canvas, or do we need a broader design and product workspace?” Excalidraw is the obvious answer when the work is sketching, diagrams, and lightweight visual thinking. Penpot is the more ambitious answer when the board is part of a design-to-code workflow. Neither is a magical one-click Miro replacement, because Miro’s appeal is the sheer breadth of things teams can throw onto one canvas. Pick the tool that matches the work you actually do, not the demo board someone made for a conference talk.

Why people are leaving Miro in 2026

Miro gets expensive at team scale. Its entry paid tier starts at $8 per month on monthly billing, but that figure is only the starting tier, not the total cost of running a real team on the platform. Once a visual workspace becomes part of every product meeting, workshop, research session, and planning ritual, “just one more collaborator” starts looking less like a rounding error and more like a recurring invoice strategy.

The free tier is limited to 3 boards. That is enough to test the product and not enough to run a team indefinitely unless the team enjoys deleting its own history. A small group can probably work around the limit for a while, but active projects, retrospectives, discovery work, and archived decisions quickly turn three boards into a filing-cabinet problem.

Data ownership is another reason to look elsewhere. Self-hosting is not automatically better, but it changes the relationship: the organization controls where the application runs and how it is maintained. That matters for teams with compliance requirements, internal infrastructure, or a general preference for not making a third party the permanent landlord of their working memory.

Offline access is limited too. That is a particularly awkward constraint for a tool whose basic job is putting ideas on a large visual surface. If the use case includes unreliable connectivity, controlled environments, or simply wanting the board to remain useful during a network outage, a hosted-only workflow deserves scrutiny before it becomes institutional habit.

The alternatives that matter

Excalidraw

Excalidraw is the closest fit for people who use Miro primarily as a fast, low-friction sketchpad. Its GitHub description is refreshingly direct: “Virtual whiteboard for sketching hand-drawn like diagrams.” The hand-drawn visual language makes rough architecture diagrams, flows, and workshop notes feel intentional rather than like failed attempts to recreate polished design software. It replaces the canvas part of Miro well, especially when the goal is thinking together rather than managing a sprawling project artifact.

Excalidraw supports both self-hosting and official cloud hosting, and its deploy difficulty is listed as 1. That makes it the pragmatic first experiment for a team that wants control without turning migration into a new infrastructure program. Its official SaaS price is $6 per month, so the hosted option is not automatically zero-cost; the important distinction is that self-hosting is available and the tool’s scope is narrower. This is a whiteboard and diagramming alternative, not a full attempt to absorb every collaborative workflow Miro has accumulated.

Pick Excalidraw if your team wants quick diagrams, workshop canvases, and an interface that stays out of the way. Pick it if “hand-drawn” is a feature rather than a visual defect and if the ability to self-host matters. Skip Excalidraw if you need a design platform, a deeply structured product-design workflow, or a broad replacement for every kind of Miro board. It is focused, which is exactly why it is useful and exactly why it will not cover every migration.

Penpot

Penpot is a different kind of alternative. Its GitHub description calls it “The open-source design platform for Product teams that need scalable collaboration,” while its tagline positions it as “The open-source design tool for design & code collaboration.” That puts it closer to the product-design side of the Miro-to-Figma spectrum than to a general-purpose whiteboard. If your Miro usage is mostly product discovery that eventually turns into interface design and handoff, Penpot is the candidate with the clearest chance of becoming part of that larger workflow.

Live metrics: 59248 stars, 4009 forks, MPL-2.0 license, last push 2026-08-27, 778 open issues.

Penpot supports self-hosting and official cloud hosting, but its deploy difficulty is listed as 3. That is not a dealbreaker; it is a reminder that “open source” does not mean “someone else handles the deployment.” Penpot’s entry tier starts at $0 and then bills purely on volume; the supplied pricing data does not specify the free allowance or the volume dimension, so treat that as an incomplete pricing signal rather than proof that the product has no operating cost.

Pick Penpot if your audience is designers and product teams, especially when collaboration needs to connect design decisions with implementation. Its MPL-2.0 license and self-hosting option are meaningful for organizations that care about control and extensibility. Skip Penpot if what you really need is a casual infinite canvas for sticky notes, rough diagrams, and spontaneous workshops. Adopting a more structured design platform to replace a whiteboard can create process overhead where the team previously needed only a place to draw arrows.

Decision framework

• If you mainly sketch diagrams and workshop ideas → pick Excalidraw.
• If you need design and code collaboration for product teams → pick Penpot.
• If self-hosting with the lowest listed deploy difficulty matters → pick Excalidraw.
• If your visual work is becoming a formal product-design workflow → pick Penpot.
• If you need a broad, general-purpose canvas with minimal workflow change → validate both before migrating.
• If your main concern is control of where the tool runs → choose the self-hosted option that your team can actually maintain.

What to watch for

Migration friction starts with the boards themselves. The supplied data establishes that Excalidraw and Penpot can be self-hosted or used through official cloud hosting, but it does not establish that either product can import every Miro board intact. Do not assume that a Miro export will preserve layout, comments, embedded material, permissions, or collaboration history. Before committing, export a representative set of boards and test the result: one simple diagram, one messy workshop board, one board with lots of accumulated material, and one board that still matters to an active project.

The second problem is feature mismatch. Excalidraw is explicitly positioned around hand-drawn diagrams, while Penpot is positioned around scalable product-team design and design-to-code collaboration. Those are useful overlaps with Miro, not identical product surfaces. A team may end up keeping Miro for broad workshops while moving selected work to Excalidraw or Penpot, which is not a failure if it reduces cost and clarifies ownership. It is only a failure if the migration is sold as a complete replacement before anyone checks what the team actually uses Miro for.

Self-hosting also moves responsibility rather than deleting it. Excalidraw’s deploy difficulty of 1 makes it the easier operational trial from the supplied data; Penpot’s deploy difficulty of 3 suggests more setup and maintenance planning. Either way, the team should decide who owns upgrades, backups, access control, and recovery before treating self-hosting as a checkbox. Open source gives you more control over the system. It does not provide free operations.
