Sketch Docker Compose stacks as diagrams and turn them into working YAML
Represent services and their relationships as a diagram so the shape of a multi-container stack is readable without parsing YAML line by line.
Start from predefined setups including WordPress with MySQL, React with Express and MySQL, Nginx with PHP and MySQL, and an Elasticsearch stack with Kibana, Logstash, and APM.
Begin with an empty diagram when your architecture does not match any template and assemble the services yourself.
See how containers, databases, and supporting components fit together before you run them, which helps catch missing links early.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.

Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.

Dedicated diagramming platform with strong AI chart generation, but less focus on freeform collaborative brainstorming whiteboards.
SpecialistInstantly turns natural language prompts into mind maps and flowcharts, but offers less freeform canvas drawing flexibility.
Combines whiteboarding and documentation with AI generation, but lacks Whimsical's specialized wireframe shape library.
Exceptional UI wireframing and prototyping tools, but less versatile for general mind mapping and freeform brainstorming.

SpecialistTransforms documents into strategic diagrams using AI, but less refined for everyday collaborative visual brainstorming.
