Excalidraw - A Self Hosted Diagram and Drawing Portal
Excalidraw is a self-hosted, freehand drawing and diagramming tool that allows users to create and collaborate on simple, visual representations of ideas.
It is a web-based application that can be accessed through any modern web browser, and its user interface is simple and intuitive.
One of the most noteworthy features of Excalidraw is its ease of use. Its minimalistic design means that users can start creating and editing drawings with very little learning curve. The tool offers basic drawing features such as shapes, lines, and arrows, and allows for simple color customization. Users can also add text to their drawings and create layers for organizing content.
Excalidraw's collaborative features are also impressive. The tool allows users to invite collaborators to work on the same drawing in real-time, making it ideal for teams working on a project or for remote collaboration. Users can also export their drawings in various formats, including PNG, SVG, and JSON.
In terms of its versatility, Excalidraw is a great tool for a wide range of use cases. For example, it can be used for sketching out UI designs, creating flowcharts or mind maps, or simply jotting down quick ideas. Its simple, flexible design makes it easy to adapt to different use cases and workflows.
To use Excalidraw for self-hosting using Docker, you will need to follow these steps:
If you're new to self-hosting, don't worry, we have guides available to help you get started with self-hosting. There you can quickly learn how to install Docker on your system.
- Open a terminal on your local machine.
- Pull the Excalidraw Docker image from Docker Hub by running the following command:
docker pull docker.io/excalidraw/excalidraw:latest
- Once the image has been pulled, run the following command to start Excalidraw:
docker run -p 8080:80 -d docker.io/excalidraw/excalidraw:latest
- Excalidraw should now be accessible at
http://localhost:8080in your web browser.
Note: The -p flag maps the container's port 80 to port 8080 on your local machine. If port 8080 is already in use, you can choose a different port number.
By default, Excalidraw will run in a development environment with hot-reloading enabled. To run the app in a production environment, you will need to follow additional steps, such as configuring a web server and setting up a production build. You can find more information on the Excalidraw GitHub repository and documentation.
Once you have Excalidraw up and running, you can use it to create and collaborate on drawings and diagrams without relying on any external service or platform. Self-hosting Excalidraw gives you more control over your data and privacy, and allows you to customize the app to suit your specific needs.
One downside to Excalidraw is that it is still a relatively new tool, and as such, it does not offer some of the advanced features of more established drawing and diagramming tools. For example, it does not offer complex shapes or advanced image editing capabilities. However, this is not necessarily a major drawback for most users, as Excalidraw's simplicity and ease of use are its main selling points.
