🐧 No apt, dnf, Snap, or Flatpak — Just a Browser Tab

Free Online Whiteboard for Linux — No Install, Runs Locally

A full-featured whiteboard that runs entirely in your browser — no package manager, no dependencies, no daemon running in the background. Works the same on Ubuntu, Fedora, Debian, Arch, Mint, Pop!_OS, and even ARM-based boards like the Raspberry Pi. Everything happens client-side, with nothing sent to a server.

Online whiteboard interface with sticky notes and drawing tools

No Package Manager, No Dependencies, No Daemon

The Linux way of avoiding software you don't need.

Most whiteboard apps on Linux mean digging through a Flatpak repo, adding a Snap, or compiling something from source — and then dealing with missing libraries, sandboxing permission prompts, or a tray icon that starts on every boot. OnlineWhiteboard.org sidesteps all of it: there's nothing to apt install, nothing to flatpak install, and nothing running when you're not using it. It's just a tab.

Because it's browser-based, it doesn't care whether your display server is Wayland or X11, or whether you're running GNOME, KDE Plasma, XFCE, Sway, or i3. There's no GTK/Qt theming mismatch, no font rendering quirks tied to your desktop environment — the canvas looks and behaves identically everywhere.

Privacy-first by design: All drawing, sticky notes, and images are processed locally in your browser's memory. Nothing is uploaded, logged, or tracked — a natural fit for users who chose Linux specifically to avoid software that phones home.

Runs on Desktop Distros and Raspberry Pi

If it can run a modern browser, it can run this whiteboard.

🐧

Any Major Distro

Ubuntu, Fedora, Debian, Arch, Mint, Pop!_OS, openSUSE — works identically as long as you have Chrome, Firefox, or Chromium.

🖥️

Wayland & X11

No display-server-specific quirks — drawing, touch, and stylus input work the same under Wayland compositors or X11.

🍓

Raspberry Pi & ARM

Runs in Chromium on Raspberry Pi OS and other ARM-based Linux boards — useful for kiosk displays, classroom Pi setups, or low-power desks.

🪶

Lightweight Desktop Environments

Works fine on XFCE, LXQt, or minimal window manager setups (i3, Sway, Hyprland) — just needs a browser window.

🔒

No Background Process

Closes completely when you close the tab. No system tray icon, no auto-start, no update notifications.

🧩

Architecture Diagrams

Sketch system designs, network topologies, and database schemas with shapes, connectors, and arrows — handy during pair programming or design reviews.

📄

PDF & PNG Export

Export diagrams as PDF or PNG straight to your Linux Downloads folder — no watermark, no account.

💾

Save Project Files

Save your board as a project file anywhere on your filesystem and reopen it later in the browser.

🌙

Dark Mode

Dark canvas mode that matches GTK or Qt dark themes for a consistent look across your desktop.

How to Start on Linux

Open a browser — your whiteboard is ready.

Open Chrome, Firefox, or Chromium

Navigate to onlinewhiteboard.org. No apt, no flatpak, no AppImage — the whiteboard loads directly in a browser tab on any distro, desktop environment, or display server.

Sketch with Mouse, Touch, or Stylus

Draw diagrams, system architectures, or notes with the pen, shape, and connector tools. Drag images from your file manager onto the canvas to annotate.

Export and Save

Export as PNG or PDF for documentation, or save a project file to your filesystem to continue later — all without an account.

Frequently Asked Questions

Do I need to install anything via apt, dnf, Snap, or Flatpak?

No. OnlineWhiteboard.org runs entirely in the browser — there's nothing to download, package, or compile. Open the site and start drawing.

Does it work under Wayland or only X11?

Both. Since it's browser-based, it works identically under Wayland compositors (GNOME, KDE Plasma, Sway, Hyprland) and under X11.

Can I run this on a Raspberry Pi?

Yes — it runs in Chromium on Raspberry Pi OS and other ARM-based Linux systems, making it usable for low-power desks or classroom kiosk setups.

Will it run on a minimal window manager like i3 or Sway?

Yes — all it needs is a browser window. There's no desktop-environment integration required.

Does it run any background processes or telemetry?

No. There's no daemon, tray icon, or auto-start. Everything stops when you close the tab, and no data is sent to any server.

Can developers use this for architecture diagrams?

Yes — the shape, connector, and arrow tools work well for sketching system designs, database schemas, and network diagrams during code reviews or pair programming.
