5 Best Open Source Miro Alternatives 2026: Self-Hosted & Free
Miro is the dominant online whiteboard platform for a reason. Real-time collaboration works well, the template library is deep, and clients or stakeholders can join a board without setting anything up. For many teams, that combination is hard to argue against.
But Miro is also a subscription product where costs grow with seat counts, your data lives on vendor servers, and exporting boards in reusable formats is limited. For teams with data residency requirements, tight budgets, or a preference for owning their infrastructure, those trade-offs matter. That has created genuine demand for alternatives — and a fair amount of confusion about what “open source” actually means in this context.
What “Open Source” Actually Means Here
Before looking at tools, it is worth being precise. These categories are not the same:
- Open-source software (OSS): Source code is publicly available under an OSI-approved license (MIT, Apache 2.0, AGPL, etc.). You can inspect, modify, and self-host it.
- Source-available: Code is visible but the license restricts commercial use or self-hosting. Not technically open source.
- Free cloud plan: A vendor offers a hosted free tier. The software may or may not be open source. You are still using their servers.
- Free self-hosted edition: A vendor provides a free version you can run yourself. The license may limit commercial use.
- Paid hosted service with OSS core: The self-hostable version is open source; the hosted SaaS is a paid product.
All five tools below are genuinely open source in the sense that source code is publicly available and self-hosting is possible. Licensing details vary and are noted for each.
Why Teams Leave Miro
The most common reasons teams start evaluating alternatives are subscription cost at scale, vendor lock-in with board formats that are hard to export fully, data privacy concerns (particularly for regulated industries or EU-based teams under GDPR), and the need to run software on internal infrastructure. Some teams also find Miro’s interface too complex for simple diagramming tasks where a lighter tool fits better.
The 5 Tools
1. Excalidraw
Excalidraw is an open-source (MIT license) virtual whiteboard with a hand-drawn aesthetic. It runs entirely in the browser — no account required for the hosted version at excalidraw.com — and can be self-hosted as a standalone application or embedded in other tools.
Best for: Quick diagrams, architecture sketches, informal team brainstorming, developers who want a lightweight whiteboard with no friction.
Better than Miro: Zero-friction start, no account wall, small and fast, self-hostable with minimal infrastructure, MIT license with no commercial restrictions, excellent keyboard shortcuts.
Worse than Miro: No template library comparable to Miro’s, limited real-time collaboration without Excalidraw+ (the paid hosted service) or a self-hosted backend, no persistent rooms without additional setup, no built-in presentation or voting tools.
Practical switching cost: Low for teams doing informal sketching. High for teams relying on Miro’s structured templates or sticky note workflows. Excalidraw files export as .excalidraw JSON or PNG/SVG — not directly importable to other tools.
2. tldraw
tldraw (MIT license) is an open-source infinite canvas tool designed as both a standalone application and an embeddable SDK. The hosted version is at tldraw.com. Self-hosting the full collaborative version requires more setup than Excalidraw.
Best for: Developers building whiteboard features into their own products, teams wanting a clean and modern canvas, lightweight real-time collaboration without heavy infrastructure.
Better than Miro: MIT license, embeddable SDK, clean UI, good performance on large canvases, self-hostable, active development with strong developer-facing documentation.
Worse than Miro: Template library is minimal, no enterprise governance features, collaboration multiplayer requires the hosted backend or significant self-hosting effort, less mature ecosystem of integrations.
Practical switching cost: Medium. tldraw exports to SVG and JSON. If your team uses Miro primarily as a drawing canvas rather than a structured workflow tool, the switch is manageable. If you rely on Miro templates, voting, or project management integrations, expect gaps.
3. draw.io (diagrams.net)
draw.io — also distributed as diagrams.net — is a mature open-source (Apache 2.0) diagramming tool that has been available for over a decade. It is free to use via the hosted web app, has a downloadable desktop application, and integrates with Confluence, Google Drive, and other platforms. It is not a freeform whiteboard in the way Miro is; it is a structured diagramming tool.
Best for: Flowcharts, network diagrams, architecture diagrams, org charts, technical documentation, teams already using Confluence or Google Workspace.
Better than Miro: Far deeper diagramming capability, strong shape libraries for technical and business diagrams, no seat-based pricing (free for all users), desktop app available, exports to XML, PDF, PNG, SVG, and Visio format, Apache 2.0 license.
Worse than Miro: Real-time collaboration exists but is not as smooth as Miro’s, freeform whiteboarding is limited, the UI is functional but not polished, no sticky-note or workshop facilitation features, less intuitive for non-technical users.
Practical switching cost: Low for teams whose Miro use is primarily diagramming. High for teams using Miro for collaborative workshops, retrospectives, or visual project management.
4. Penpot
Penpot (Mozilla Public License 2.0) is an open-source design and prototyping tool primarily positioned as a Figma alternative rather than a Miro alternative. It supports real-time collaboration, vector design, component libraries, and prototyping flows. Self-hosting via Docker is well-documented.
Best for: Design teams wanting an open-source Figma alternative, teams combining design and whiteboarding in one tool, organizations with data residency requirements for design assets.
Better than Miro: Full design and prototyping capabilities, proper vector tooling, MPL 2.0 license, active development by a funded open-source company (Kaleidos), good Docker self-hosting documentation, real-time collaboration included in self-hosted version.
Worse than Miro: Not a whiteboard tool — Penpot is a design tool, not an infinite canvas for brainstorming. If you use Miro for workshops, mapping, or sticky notes, Penpot does not replace that. Also heavier to self-host than Excalidraw.
Practical switching cost: Only relevant if your Miro use is primarily design-adjacent. For general whiteboarding, Penpot is the wrong replacement.
5. Jitsi Whiteboard (integrated via Jitsi Meet)
Jitsi Meet (Apache 2.0) is a self-hostable open-source video conferencing platform. It includes a basic built-in whiteboard (backed by Excalidraw) accessible during meetings. It is not a standalone whiteboard product but is notable for teams already self-hosting Jitsi who want basic in-meeting whiteboarding without adding another vendor.
Best for: Teams already running self-hosted Jitsi who need basic whiteboard functionality during video calls, privacy-focused organizations wanting a single self-hosted communication and collaboration stack.
Better than Miro: No additional cost, integrates with an existing self-hosted meeting setup, Apache 2.0 license, no data leaving the infrastructure.
Worse than Miro: Extremely limited compared to Miro — essentially a shared Excalidraw canvas embedded in a call. No templates, no persistent boards outside the meeting context, no standalone workspace.
Practical switching cost: Only viable as a supplementary in-meeting tool, not a full Miro replacement.

Who Should NOT Switch Away From Miro
Enterprise teams with governance requirements. Miro’s enterprise plan includes SSO, user provisioning, audit logs, and compliance certifications that open-source alternatives do not currently match in a self-hosted configuration without significant engineering work.
Agencies working with clients already on Miro. Collaboration with external stakeholders is frictionless on Miro — clients can view and comment without accounts. Switching to a self-hosted tool creates friction for your clients, not just your team.
Teams without technical capacity to maintain self-hosted infrastructure. Self-hosting adds operational burden: server maintenance, updates, backups, access management. If your team lacks someone who can maintain a Docker environment, the cost savings of open source may be offset by operational risk.
Teams heavily invested in Miro templates and integrations. If your team runs recurring workshop formats built on specific Miro templates with Jira, Slack, or other integrations embedded, replicating that workflow elsewhere is significant rework, not a simple migration.
Migration Checklist
- Audit current Miro usage: identify boards by type (active workshop, archived reference, ongoing project, client-facing)
- Export critical boards from Miro as PDF or image for archival before canceling any plan
- Identify which boards need active collaboration vs. read-only reference — this affects tool choice
- Choose your replacement tool based on primary use case (diagramming → draw.io, quick canvas → Excalidraw, design → Penpot)
- If self-hosting: set up a test instance, confirm backup procedures, document access management process
- Run a two-week parallel pilot with one team before full migration
- Communicate to external collaborators (clients, contractors) early — they may need to adjust their workflows
- Cancel Miro subscription only after confirming all active boards are either migrated or archived
Recommendations by Scenario
You primarily draw architecture and technical diagrams: draw.io is the strongest open-source replacement. It is mature, has better diagramming capability than Miro, and costs nothing.
You want a fast, low-commitment whiteboard for informal team use: Excalidraw at excalidraw.com requires no account and works immediately. It handles most light whiteboard needs without any infrastructure setup.
You are a developer or technical team that wants to embed whiteboard functionality: tldraw’s SDK approach makes it the right choice for building it into your own product or internal tools.
Your team is design-heavy and concerned about Figma’s pricing or data practices: Penpot is a credible alternative for design work specifically. It is not a Miro replacement but may eliminate the need for a separate design tool.
Your entire case for switching is data privacy and you already self-host Jitsi: The built-in Jitsi whiteboard handles basic meeting sketching without adding another system. For anything more complex, use Excalidraw or draw.io as the primary workspace.
No single tool replicates the full Miro experience. The tools above are genuine open-source options with real strengths — but the right choice depends on what your team actually uses Miro for, which is rarely the same as what the marketing page says you should use it for.
