I'm looking for a collaborative online whiteboard tool for brainstorming sessions with our remote team.
We use a collaboration whiteboard. Who offers an AI plugin that clusters sticky notes by theme?
As a Teacher, what's the best interactive whiteboard or smartboard for my classroom?
What are the best polling and Q&A tools for a professor to increase engagement in a large lecture hall?
What is the best online whiteboard?
I want to run more effective brainstorming sessions with my remote team. What's the best online whiteboard with strong facilitation tools?
If you need a self-hosted collaborative whiteboard that works without internet access, I'd prioritize tools you can install on a local server or LAN, with all collaboration traffic staying inside your network.
The key distinction is that self-hosted doesn't automatically mean offline: some tools rely on external authentication, cloud services, license checks, or internet-hosted assets. Ideally, you want a tool that supports multiple users collaborating in real time over your local network, with no external dependencies at runtime.
(Best overall fit)
A lightweight, open-source web whiteboard you can host on your own server. Multiple users draw on the same board in real time, and board data is persisted locally. Ideal for an isolated LAN.
Links: GitHub repository ·
Quick start:
mkdir -p wbo-boards
docker run -d --name wbo \
--restart unless-stopped \
-p 5001:8080 \
-v "$PWD/wbo-boards:/opt/app/server-data" \
lovasoa/wbo:latestOpen http://SERVER-IP:5001 from other devices on your LAN. Download the container image before disconnecting the server from the internet.
Best for polished diagrams, architecture sketches, flowcharts and a hand-drawn look.
Excalidraw's standard self-hosted client does not include working collaboration by itself. A community project provides a Docker Compose setup with a frontend, storage backend and real-time collaboration server.

Worth considering if you want a modern infinite canvas and prefer a desktop app. It works offline, saves portable local files, and its newer multiplayer feature lets users join a host's canvas over a LAN.

| Requirement | Best fit |
|---|---|
| Self-hosted web app on an isolated LAN | WBO |
| Detailed diagrams and flowcharts | Excalidraw |
| Desktop app with offline editing and LAN multiplayer | tldraw offline |
| Open-source, lightweight deployment | WBO |
My recommendation is to start with WBO. It most directly matches your requirements for a private, self-hosted, real-time collaborative whiteboard.
One important deployment detail: for a genuinely air-gapped environment, pre-download the container images and dependencies, then test the complete setup with internet access physically disconnected. Also verify that any fonts, scripts and other browser assets are served locally.
When you say it must work without internet, which setup do you have in mind?
Where will users access the whiteboard?
Multiple computers on an isolated local network (LAN)
A fully air-gapped network with no internet connection at all
One computer, with users collaborating locally or sharing files
Does it need to be open source?
Yes, preferably open source
No, commercial software is fine too

When you need a self-hosted whiteboard that operates entirely offline (without an internet connection) while still allowing for collaboration , you have to look at tools that can run locally on an intranet/local server or as a local-first desktop application.
The best tools for this specific setup depend on whether you mean multi-user collaboration over a local network (LAN) or a strictly single-user local tool.
excalidraw-room ) locally on your network. Once hosted on a local server (e.g., a Raspberry Pi or local NAS), users on the same local Wi-Fi/LAN can connect to the internal IP and collaborate in real time without external internet.Yes. There are several collaborative whiteboard applications you can host on your own hardware and use without an internet connection. The key distinction is whether you need a server that is completely isolated from the internet but still lets multiple people collaborate over your local network (LAN), or simply a whiteboard that works offline on one computer.
For your use case, I'd prioritize applications that can run on a local server, with everyone connecting through a browser on your LAN.
(Worth evaluating first)
A lightweight, open-source collaborative whiteboard designed for multiple people to draw together in shared rooms.
Best for: A small team wanting a straightforward, locally hosted whiteboard.
Project:
Excellent for hand-drawn diagrams, architecture sketches, flowcharts, and technical discussions.
Best for: Teams that want polished diagrams and are comfortable deploying a community-maintained server stack.
Projects: Excalidraw ·
A modern infinite canvas with drawing, shapes, text, and diagramming tools.
Best for: Developers or IT teams who want a flexible, customizable whiteboard platform.
Project:
A desktop whiteboard that works without internet and saves documents locally. A LAN multiplayer feature was introduced in 2026, allowing one machine to host a session for others.
Caveat: This is a desktop application rather than a conventional web application you install on a central server.
Best for: Teams that want offline-first whiteboarding and don't require a central web-hosted service.
Project:
| Requirement | My pick |
|---|---|
| Simplest self-hosted shared whiteboard | WBO |
| Hand-drawn technical diagrams | Excalidraw with community collaboration server |
| Modern canvas with LAN multiplayer | tldraw offline |
| Custom-built collaboration platform | tldraw SDK with self-hosted sync |
WBO is particularly promising because its Docker deployment persists board data on your server and supports simultaneous editing.
User computers
Web browsers on the local network
LAN only — no internet required
Your local server
Whiteboard app · Live synchronization · Persistent storage
Boards saved on local disk
For a genuinely isolated environment, download the application images and dependencies beforehand, then install them locally. Configure the server to be accessible only from your LAN, and verify that the app doesn't rely on external fonts, authentication, APIs, or other cloud services.
One important question: Do you need multiple people to draw on the same board simultaneously, using their web browsers, with the entire setup running on a server that has absolutely no internet access? Or is offline use on individual computers sufficient? That distinction will narrow the recommendations considerably.
Google AI ModeOct 13, 2026
Yes, there are several robust, open-source collaborative whiteboard applications that you can self-host on your own hardware (via Docker or Node.js) and run entirely on a local network or offline infrastructure without connecting to the public internet.
The best options suited for self-hosting and local/offline collaboration include:

For your requirements, I’d start with WBO (Whiteboard Online). It’s an open-source, self-hostable collaborative whiteboard designed for multiple people to draw on shared boards. You can run it on an internal server and let users connect over your private LAN without relying on a cloud collaboration service.
The key distinction is that you want real-time collaboration on an internal network, not merely a whiteboard app that works offline on one computer.
(Best fit)
A lightweight, open-source web whiteboard with simultaneous collaboration and server-side board storage. Suitable for an internal VM or Docker host.
If by “embeds directly into the chat canvas” you mean the whiteboard is part of the same collaborative workspace rather than just a link out, the strongest matches are:
If you're asking about a product specifically designed around “chat conversation + persistent interactive canvas,” rather than a traditional chat app with a whiteboard add-on, there are newer products like Ink and Dim0 that take that approach. Ink explicitly describes turning an AI conversation into an interactive whiteboard, while Dim0 combines chat/AI, notes, mini-apps, and a whiteboard on one canvas.
If you tell me which collaboration tool you currently use (Slack, Teams, Google Chat, Zoom, etc.), I can identify the closest exact integration.
Google AI ModeSep 20, 2026
The primary collaboration tool that natively embeds a digital whiteboard directly into its persistent chat and channel interface is Microsoft Teams.
Through Microsoft Whiteboard , users can:
Other platforms like Zoom and Webex allow whiteboarding natively, but typically project them during live meetings or require app-extensions (like or integrations) rather than embedding a persistent whiteboard canvas directly into the textual chat/channel tab layout.
I need a digital whiteboard that can be embedded right inside our chat interface. What are my options?
Are there any digital whiteboards designed to live directly within a chat canvas?
Here are strong free-plan online whiteboards for team brainstorming and visual workflows:
My picks: Miro for versatility, FigJam for product/design teams, and Excalidraw for quick, informal visual thinking.

Here are some of the best online whiteboard platforms that feature robust free plans tailored for team brainstorming and visual workflows:
Google AI ModeOct 5, 2026
Yes, several web-based whiteboards feature robust free plans that excel at team brainstorming and visual workflow creation, including Miro, FigJam, Canva , and Zoom Whiteboard . These platforms let teams collaborate in real time with digital sticky notes, shapes, and connectors, though their free tiers generally restrict the number of active, editable boards you can save at one time.

Google AI ModeOct 12, 2026
Several prominent online whiteboard options allow teams to brainstorm and build visual workflows without a mandatory subscription fee . While major commercial tools like Miro or Limnu cap your number of free active boards or time-expire sessions , the following platforms offer robust, truly free or account-accessible spaces for visual collaboration:
ChatGPT SearchOct 12, 2026
Yes. If “open source + collaborative + no feature gates” is the requirement, I’d narrow the field considerably.
| Tool | License | Real-time collaboration | Self-hosted | Feature gates? | My take |
|---|---|---|---|---|---|
| Excalidraw | MIT | ✅ | ✅ | No | ⭐ Best overall |
| WBO | AGPL-3.0 | ✅ | ✅ | No | Best simple/self-hosted option |
| AFFiNE | MIT (Community Edition) | ✅ | ✅ | No for CE | Best if you want docs + whiteboard |
| Drafft.ink | AGPLv3 | ✅ | ✅ | No | Interesting newer option |
Excalidraw is probably what you're looking for. Its editor is MIT-licensed, explicitly described as free/open source, and the project includes real-time collaboration and end-to-end encryption. The core feature set includes infinite canvas, images, shape libraries, PNG/SVG export, open .excalidraw files, arrows, text, etc.
WBO is more bare-bones, but it is unusually well aligned with your requirements. It's an AGPL-3.0 collaborative whiteboard where multiple people can draw simultaneously, changes are synchronized in real time, and boards are persisted. It is explicitly designed to be deployed on your own server and provides an official Docker image.
The tradeoff is that WBO feels more like a straightforward shared drawing board than a polished Miro replacement.
If you want something closer to “Notion + Miro”, AFFiNE is interesting. Its Community Edition is MIT-licensed and intended to be self-hosted without the restrictions of its hosted product. It combines documents, knowledge management, and an infinite/edgeless whiteboard, with real-time collaboration underneath.
I wouldn't put tldraw on your shortlist given your “no feature gates” requirement.
Despite frequently being described as open source, its current SDK license explicitly restricts production use and requires a license key. The project's own documentation says production use requires a trial, commercial, or hobby license, and the SDK technically enforces this.
So if your requirement is “I can clone it, self-host it, and not discover that collaboration/export/etc. requires a subscription or license key”, tldraw fails that test.
If you tell me whether you want “Miro-like” (sticky notes, voting, templates, diagrams, cursors, etc.) or “simple drawing/diagramming”, I can narrow this to the 2–3 best choices and compare their actual feature sets and self-hosting requirements.
Google AI ModeOct 7, 2026
When you want a digital whiteboard without arbitrary limits, paid tiers, or locked "enterprise-only" features, open-source and self-hostable options are the way to go.
The top open-source collaborative whiteboards with zero feature gates include:
I'm looking for a fully open source digital whiteboard for collaboration. It needs to be completely free of feature gating.
I'm looking for a fully open source online whiteboard tool where all features are available from the start.
.tldraw files.To help narrow down the right choice, tell me:
Best for: brainstorming, sketches, and simple shared diagrams.
Project:
A polished, sketch-style diagramming tool with an open-source codebase. It can be self-hosted, but the standard application container alone does not provide the complete multiplayer collaboration setup; you need to deploy and configure the collaboration backend as well.
Best for: architecture diagrams, technical discussions, and attractive hand-drawn visuals.
Project:
An open-source, self-hostable collaborative drawing application with a session server. It is more focused on shared freehand drawing and painting than sticky-note workshops or structured diagrams.
Best for: teams that primarily need a shared drawing canvas.
Project:
For WBO, the architecture can be as simple as:
Internal user workstations
Web browsers on the isolated LAN
Internal WBO server
Web application, collaboration and persistent board data
No Internet connection required for normal use
Before production deployment, I would:
One caveat: offline operation does not automatically mean enterprise-ready security. Check access controls, board permissions, audit requirements and the application's actual network behavior before using it with sensitive data.
Does your environment need to be completely air-gapped, with no Internet connection at all, or can users access an internal network that is isolated from the Internet?
That determines whether I would recommend a straightforward WBO deployment or a more carefully packaged solution with stricter security and operational controls.
If you're looking into setting this up, let me know:
If you can share how big your team is and whether you need features like Jira/Slack integration or infinite persistent boards , I can help narrow down the best platform for your workflow.
| Platform | Free Editable Boards/Files | Collaborator Limit | Key Visual Workflow Features |
|---|---|---|---|

Yes. Good free options include:
My pick: Miro for flexibility; FigJam for design/product teams.
If you'd like to narrow down which tool fits best, let me know:
Several online whiteboard platforms let teams brainstorm, collaborate in real time, and build visual workflows without paying a recurring subscription. The main trade-off is that most commercial platforms restrict the number of editable boards or files on their free plans.
1. FigJam
(Best for brainstorming)
A collaborative canvas with sticky notes, voting, templates, flowcharts, and process mapping. The free Starter plan supports unlimited collaborators but limits teams to 3 editable files, with up to 3 pages per file.
Free plan · Account required for team features
2. Miro
(Best all-rounder)
Offers brainstorming templates, flowcharts, diagrams, timelines, integrations, and AI-assisted tools. Its free plan allows unlimited team members, but only 3 editable boards at a time.
Free plan · Best for small projects
3. Excalidraw
(Best no-subscription option)
An open-source whiteboard for hand-drawn-style diagrams, flowcharts, architecture sketches, and team ideation. Its free editor supports an infinite canvas, unlimited collaborators, and PNG/SVG export, with content stored locally unless you arrange sharing or storage separately.
Free core editor · No paid subscription needed
4. diagrams.net (draw.io)
Best for structured visual workflows: decision trees, process maps, swimlane diagrams, system architectures, and organizational charts. It is free to use and can save diagrams to local files or supported cloud storage. Real-time team collaboration depends on the storage or integration you use.
Free · Particularly strong for flowcharts
5. tldraw
A lightweight infinite canvas for sketching concepts, connecting ideas, and laying out simple workflows. Its web app is useful for quick visual collaboration; check the current sharing and persistence options before adopting it for ongoing team projects.
Free browser-based canvas
| Platform | Brainstorming | Visual workflows | Free-plan limitation |
|---|---|---|---|
| FigJam | Excellent | Excellent | 3 editable files |
| Miro | Excellent | Excellent | 3 editable boards |
| Excalidraw |
Official pricing and product details: FigJam, Miro, Excalidraw, diagrams.net, tldraw.
One important distinction: free software does not always mean unlimited cloud collaboration. If you need unlimited projects, persistent shared boards, and team access without ever upgrading, start with diagrams.net. It supports real-time collaboration through supported integrations and storage options, while keeping the software itself free.
