Overview
This AMI runs a self-hosted virtual whiteboard for sketching diagrams and notes in the browser, on Ubuntu 24.04 LTS. Drawings are made and kept in your browser. The container image (2026-05-06) is pinned and pre-installed in the AMI.
What Perimattic adds
Login created for you: a random 24-character password for the one login is generated on your server during first-login setup, and every page needs it. Apache provides HTTPS with a free Let's Encrypt certificate for your domain.
Limits you should know
Collaboration rooms, share links, AI features and the library catalogue are not available. Outside services used by the standard page, such as analytics and web fonts, are blocked. The vendor publishes only a 'latest' image, so it is pinned by digest and receives no version updates until a new AMI is built. A t3.small (2 GB) is the recommended starting size.
Licence and attribution
The whiteboard application is released under the MIT licence; this AMI runs the unmodified upstream image. The fonts bundled with it are distributed under the SIL Open Font License. Built on the open-source Excalidraw (MIT). Not affiliated with, endorsed by, or sponsored by Excalidraw; Excalidraw is a trademark of its owner.
Getting Started Launch the AMI and open ports 22, 80 and 443 in the security group SSH in and answer the setup prompts (domain and admin email) Open https://your-domain and sign in with the user name admin and the password printed at the end of setup Draw, then export your work from the menu
A domain name with an A record pointing at the instance is required, because the site is served over HTTPS.
This AMI is built and supported by Perimattic.

Highlights
- Virtual whiteboard (MIT, upstream build of 2026-05-06, pinned by digest) with a hand-drawn look; a static web app, so the server stores no drawings.
- Private by default: Apache asks for a generated 24-character password, and a content security policy keeps the browser from contacting outside services such as analytics or sharing hosts. HTTPS through Apache and Let's Encrypt.
- Built on patched Ubuntu 24.04 LTS and supported by Perimattic: free setup assistance at aws-support@perimattic.com.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Initial release.
- Application: Virtual Whiteboard 2026-05-06 (container image pinned, baked into the AMI).
- Base: Ubuntu 24.04 LTS, fully patched at build time, built by an automated EC2 Image Builder pipeline.
- TLS: Apache reverse proxy with a Let's Encrypt certificate requested by certbot at first login.
- Credentials are generated on the instance at first login; none are present in the image.
- A random 24-character password is generated at first login and stored only as an Apache password hash; Apache asks for it before serving anything, and setup verifies the hash. A content security policy lets the browser contact this site only.
- Application: upstream whiteboard image built 2026-05-06 (MIT, unmodified, pinned by digest; the vendor publishes no version tags). The container is read-only with extra privileges dropped.
- Live collaboration, share links, the AI feature and the shared library catalogue do not work (they need the vendor's online services).

Usage instructions
-
Launch an Instance
From AWS Marketplace, click Continue to Subscribe and then Continue to Configuration to launch the AMI.
-
Choose the Recommended Instance Type
t3.small (2 GB of memory) is the recommended size for headroom: the whiteboard container used about 10 MB in our tests, since it only serves static files.
-
Configure Security Group
Allow inbound traffic on the following ports:
- 22 (SSH) - terminal access for setup
- 80 (HTTP) - needed to validate your domain for the TLS certificate
- 443 (HTTPS) - access to Virtual Whiteboard
-
Point a domain at the instance
Create a DNS A record (for example board.example.com) pointing to the instance's public IP before you log in.
-
Connect to the Instance
ssh -i <your-key.pem> ubuntu@<public-ip>
-
First-Login Setup
The first SSH login runs a guided setup:
- Prompts for your domain and admin email and checks the DNS A record
- Generates a random 24-character password on your server and stores it only as an Apache password hash
- Starts the whiteboard container and checks that it serves the page and that the stored hash accepts the password and rejects another
- Configures Apache as an HTTPS reverse proxy that asks for the password and sends a content security policy, and requests a Let's Encrypt certificate
- Prints the URL, username and password; they are also stored in /opt/app/access.txt (root only)
If a step fails, fix the problem shown and log in again: the setup resumes where it stopped.
-
Access Virtual Whiteboard
Open https://<your-domain> and sign in with the user name admin and the password printed at the end of setup (view it again with: sudo cat /opt/app/access.txt). Drawings stay in your browser: export what you want to keep.
-
Credentials
Generated on your server, never shared between customers. View them again with:
sudo cat /opt/app/access.txt
-
Manage the Services
cd /opt/app sudo docker compose ps sudo docker compose restart
The server stores no drawings: they live in each browser. Back up /opt/app/.env only if you want to keep the generated password; the password hash is in /etc/apache2/perimattic-whiteboard.htpasswd. Collaboration, share links, the AI feature and the shared library catalogue are not available.
