Architecture diagrams drawn by hand in a tool like PowerPoint or Miro tend to go stale fast — someone changes the system and forgets to update the picture. LikeC4 flips that: you describe your system's components and how they connect in a simple text format, and the diagrams are generated automatically from that description, so keeping the text current is enough to keep every diagram accurate. LikeC4 is a free, open-source (MIT license, ~5,100 GitHub stars) modeling language and toolset for software architecture visualization, built around the C4 Model (Context, Containers, Components, Code) and inspired by the Structurizr DSL, with added flexibility for customizable notation and nested architecture levels. It's written in TypeScript as a monorepo, ships a VS Code extension available on both the VS Code Marketplace and Open VSX, includes a CLI for local preview during development, offers a web-based playground to try it without installing anything, and supports multiple export formats.

A shared, interactive map of how a company's software systems fit together — instead of a static architecture diagram that's out of date the moment someone draws it, teams can drill down from a big-picture view into individual services, link pieces direct
A design canvas where an AI agent sits next to you and builds interfaces, graphics, and slide decks with you — and unlike most design tools, what you draw isn't a picture of an app, it IS the app: every design maps 1:1 to real React and Tailwind code, so
A free Google Labs tool where you describe an app screen out loud, by text, or by sketching on paper and photographing it, and it generates a real, editable interface design — plus the actual React and Tailwind code behind it — so a non-designer can get f
A free library of pre-built, animated building blocks for websites — instead of a developer hand-coding a fade-in effect or a particle background from scratch, they copy a ready-made component into their project and adjust it, the same way people already
A browser extension that takes a snapshot of your actual live product — not a blank canvas — so a product manager can describe a change in plain English and see it applied to a real, clickable copy of the app, without waiting on a designer or developer to
PixyCAD lets you sketch a part with an Apple Pencil on your iPad and turns it into a real, printable 3D model — built for hobbyist makers, not the engineering teams that professional CAD software like Fusion 360 targets.
Instead of an AI generating a landing page from a blank prompt and hoping it looks good, Acebuilder starts from professionally-designed Aceternity UI templates and lets AI fill in and rearrange the content — so the output doesn't look generic.
Describe a poster, slide deck or social graphic in plain English and Kodo hands you back a fully editable design — not just a flat image.
An open-source visual editor that lets designers edit a real React website by clicking and dragging — like Figma, but the changes go straight into the actual code.
AI tool that turns chat prompts into working UI prototypes matching your existing design system, exportable to React and Figma.
