Diagrams, for people who ship.
Practical writing for software and DevOps teams: turning code and infrastructure into diagrams, working together, and why a hand-drawn look does more than you think.
From docker-compose.yml to a clean architecture diagram in seconds
Stop redrawing your stack by hand. Paste a Compose or Kubernetes file and LetDraw lays out the architecture, clusters your services and stamps the right product icons, ready to edit and export.
From prompt to architecture: building systems visually with AI
Describe a system in a sentence, get a first-draft architecture, then shape it into something you would put in a design doc.
Generate UML diagrams with AI
Class and sequence diagrams are exactly the structured drawing AI is good at. Go from a description or code to editable UML.
From API documentation to an architecture diagram with AI
Your OpenAPI spec already describes your resources and how they relate. Turn that into a diagram instead of reading YAML.
Turn code into diagrams, and diagrams into code, with AI
Keep a diagram in two synced forms: reviewable code and a readable visual, and move freely between them.
Visualizing Kubernetes: pods, services, ingress and gateways
The hard part of Kubernetes is the request path. A diagram of pods, services, ingress and gateways makes it click.
How to create an AWS architecture diagram
A good AWS diagram is nested boundaries, not a pile of icons. Draw region, VPC, zones and subnets so the layout reads.
How to visualize a production cloud architecture
The design-doc architecture and the running one differ. Draw the real one: traffic path, failure domains, scaling.
How to visualize a microservices architecture
Microservices diagrams turn into spaghetti. Keep it legible with boundaries and edges styled by communication type.
AI-powered diagramming: the future of technical diagrams
Where AI genuinely helps with technical diagrams, where it does not, and what a diagramming tool should do with it.
Beyond diagramming: a new visual workspace for software engineers
A drawing tool gives you boxes and arrows. Modern engineering needs a surface that stays connected to the code, the infra and the team.
How to draw a system design interview diagram, fast
Build a clean, scalable architecture in the order the interview rewards, and keep the board legible while you talk.
Kubernetes YAML to a cluster diagram in one paste
Paste your manifests and see how Ingress, Services, Deployments and Pods actually connect.
ER diagrams that stay in sync with your schema
Stop hand-drawing your schema. Generate the ER diagram from the DDL you already ship, and drift becomes impossible.
Wire LetDraw into your AI agent with MCP
A hands-on setup: a token, a few lines of config, and your agent can turn a description into a real, editable diagram.
Cloud architecture diagrams done right: AWS, Azure and GCP icons
The right icons make a cloud diagram skimmable. Use the real provider sets and generate the draft from your Terraform.
Your query is slow. Here's how to see why.
Turn a Postgres or MySQL EXPLAIN plan into a heat-mapped tree and spot the expensive node at a glance.
Diagrams as code, without losing the whiteboard
Bring Mermaid and D2 in as editable shapes, tweak by hand, then export back to code when you need it.
Let your AI agent draw the diagram: the API and MCP server
Generate and export diagrams from a CI script or an AI assistant with scoped API tokens and an MCP server.
Why the best engineering docs are a little bit hand-drawn
The case for sketchy diagrams: friendlier, faster to make, and far more likely to actually get read.
Model a database schema your whole team can actually read
ER tables, crow's-foot cardinality and smart foreign-key routing that keeps lines readable.
Real-time whiteboarding for engineers, no install required
Live cursors, workspace roles and point-anchored comments, right in the browser.
Local-first, encrypted, self-hostable: diagrams that stay yours
How LetDraw keeps your work private: end-to-end encryption, strict headers, and self-hosting.
Try the thing these posts are about.
Open a canvas in your browser, paste some code, and see your architecture draw itself.
