About

DGM is a web-based sketchnoting app designed for visualizing, elaborating, and sharing ideas. Users can quickly create diagrams to bring their concepts to life. For professional users, DGM offers a variety of shape libraries, including UML, SysML, wireframes, ERD, flowcharts, DataFlow, and C4. The app supports a sketch style that allows for stress-free, low-fidelity diagram creation and enables real-time collaboration through a web browser. With AI integration, DGM can generate web applications directly from completed diagrams, as well as produce database schemas and source code in Java and other languages.

How they use Cloudflare

DGM uses Cloudflare extensively across their platform to streamline development and operations. For web application deployment, DGM relies on Cloudflare Pages, simplifying hosting and scaling. Cloudflare Workers powers DGM’s real-time collaboration server, with Cloudflare Durable Objects handling open communication across web sockets, and data storage and Cloudflare R2 serving as their go-to solution for user file storage, backups, and image storage, enabling seamless real-time collaboration.

For small development teams, handling the deployment and management of web applications can be tough. Setting up CDNs, scaling servers, managing the front end, and configuring CI/CD often take up more time and resources than expected. Cloudflare takes care of these tasks automatically, freeing up teams to focus on building great software without the usual infrastructure headaches. Traffic spikes and frequent updates aren’t a worry anymore either. Plus, Cloudflare’s Durable Objects and Workers make setting up real-time collaboration servers simple and affordable, removing the need for complicated setups with multiple VPS instances and Redis.

Why Cloudflare?

"We chose Cloudflare because it delivers exceptional performance with its Edge Runtime, allowing our services to operate quickly from anywhere in the world. The near-zero cold startup time, compared to other serverless solutions like AWS and Vercel, gives us a significant speed advantage. Beyond performance, the low operational cost—especially with no egress fees—makes Cloudflare a clear choice. Security was also a top priority for us, and transferring all our domains to Cloudflare has given us peace of mind, protecting us from DDoS attacks and boosting our overall security."
