I downloaded and organized more than 1000 official images from AWS, Google Cloud, Azure, Firebase and others like Digitalocean, Slack etc and built this tool. I use this to generate quick architecture diagrams for my personal projects.
Here are some of the features
Offline support - Save your diagram offline in browser local storage to continue later.
PNG - Export your diagrams to png to embed anywhere.
Keyboard shortcuts
Font Awesome support
Embed anywhere - You can embed your diagram anywhere and show up-to-date diagrams in your documentation (coming soon).
There is no signup required. You can start creating your diagrams right away.
