"...honestly impressed with the product and felt a wave of relief when I discovered it. I've been struggling the last 3 months trying to find a way to diagram what's in my head in an efficient and sustainable way as things continue to evolve and change within my environment, and this with the IDE but bi-directional GUI changes etc. By god it's beautiful, the nested boards with the ability to dive in, and the "scenarios" are exactly what I want to be able to train up my Support Engineers to be able to understand the infrastructure as it's used by clientele etc."

"I have a bunch of big and complex diagrams that are needed in a certification process. We successfully use D2 for our diagrams..."

"Amazing tool, both the layout engine and the service in general. Perhaps the best I've seen around."

"D2 is a super useful new language that anyone can learn and start to use in 10 minutes or less... we can use to generate cool looking diagrams in no time. I was so happy to discover D2."

"D2 is so much prettier and more approachable compared to PlantUML while feeling more powerful and versatile than Mermaid."

"..the [D2] syntax is dead simple, it's the perfect fit for our goal."

"It took me just a few MINUTES to take a bunch of diagrams that the engineering team made and change the styling to match the look and feel of company brand for a presentation."

“D2, un langage permettant de transformer du texte en diagrammes. Vous décrivez ce que vous voulez schématiser et il générera l'image pour vous. Je l'utilise actuellement pour les diagrammes de mes livres et c'est juste 🔥.”

“D2, a language for transforming text into diagrams. You describe what you want to map and it will generate the image for you. I currently use it for diagrams in my books and it's just 🔥.”

"D2 de Terrastruct une CLI moderne qui transforme ton code en diagramme. Facile à utiliser et avec déjà pas mal de fonctionnalités 🚀 Parfait pour les féru·e·s de schéma d'archi😁"

"D2 of Terrastruct a modern CLI that turns your code into a diagram. Easy to use and with already a lot of features 🚀 Perfect for architecture scheme enthusiasts 😁"

"I never want to drag and drop shapes on a canvas to make a diagram again…Because the diagram is essentially “code” it can be versioned in source control. Making it easy to track changes over time in a visual way."

"[Tool recommendation] D2 is a new, declarative diagramming language, that can make diagramming technical diagram a breeze"

"Enter Terrastruct, which is software created to solve the problem of managing technical documentation while remaining highly customizable. With this tool, you can see changes instantly and store them in a version control system. This lets you create a densely layered process that anyone can read and appreciate, giving the technical documentation team a powerful tool while not holding the engineering team back with new requirements."

"Don't use "Draw.io"/"Diagrams.net" to create infrastructure diagrams.

Here's how it will go: "Can we please update the name of the Galactus* service and document integration with Stripe?"

And off you go on a hunt for source files, stuck with moving arrows and boxes around, feeling like a designer in Photoshop for the rest of the day. The thing is - you are not a designer - and it definitely isn't your strength.

Ten revisions later, it's finally done, and you have wasted your time and energy.

"Wasted" - because the process is tedious; thus, documentation will only be updated "upon request", leaving it outdated most of the time. What's the point of that?

Use a different tool instead.... Use D2Lang... Think "#terraform for diagrams" or 'diagrams as a code'. D2 saves countless hours in visual diagramming tools."

A friend linked me to the Terrastruct D2 diagramming language project, and though it's still a young project it is absolutely the easiest diagram as code language I've seen.

"Terrastruct is the closest thing to the ideal diagramming tool that I've been thinking about for years."

"D2 has given me and my team the ability to go from high level whiteboard concept to low level high detail diagrams where we all leave understanding how each service and operation interacts with the other in much less an amount of time than with alternatives. It has removed the issue of same question overload by giving the ability to reference a diagram as a single source of truth all while making it super easy to add touch ups along the way without hassle. D2's fault tolerant warning first approach has removed hours of headache I'd normally experience with alternative diagramming tools and has allowed me to be ahead of schedule on delivery."
