Design

Plushies

Plush, furry characters and AI-helper cursors for the web, built with Three.js

A ready-made way to give an in-app agent a visible body: a cursor with a name tag, a status box and a follow-me mode.

Recto

A free desktop canvas where Claude Code, Codex and Cursor draw UI you can edit

It gives the agent you already pay for a Figma-like surface, so design iteration happens in pixels and prompts instead of a terminal scrollback.

pixelfx

An MIT library of procedural pixel-art effects you can drop into any game engine

A solo game developer gets fire, slashes, weather and pickups for free, as code for the browser or as sprite sheets for Godot and Unity.

Warsaw in voxels

Walk central Warsaw as Minecraft-style blocks built from open map and LiDAR data

It shows how far public geodata plus an AI-assisted first draft can get one person toward a walkable city model, and the code is open to borrow.

Gifup

Trim, shrink and caption a GIF without the file leaving your laptop

Most free converters want an upload and leave a watermark; this one does the encoding on your own machine and asks for neither.

SolidCraft

Modelling with a live feature tree, in a tab or from the command line

Sketch constraints, an editable feature history and STEP in and out, free under a permissive licence, and reachable in a browser with nothing to install.

NASSCAD

Parametric solid modelling in a tab, with your files staying put

If you model the odd bracket or enclosure but resent a seat on Fusion or Onshape, this opens in a tab, costs nothing and keeps your geometry on your own machine.

GradientDeck

Taste, installed into the agent that builds your pages

If every page your coding agent produces wears the same default template, this is one command to give it rules it applies without being asked each time.

UIPalooza

Four briefs, many models, 1,784 finished pages you can open and compare

If you build frontends with a model, this is the first public side-by-side of what each one picks when the brief says nothing about styling.

Narrative Deck

An agent skill that turns raw notes into a nine-beat web article

It hands a coding agent one story structure and a fixed set of fifteen scroll effects, so what comes back reads as an article rather than a pile of slides.

ZenExport

Ctrl+S in Fusion writes a numbered revision of every print file

If you slice straight from Fusion, this keeps the editable model and the mesh you actually printed under one revision name, so you can tell which file made which part.

FigCraft

An installable design editor that opens offline and asks for no account

Design work has sat in a browser tab behind a subscription for a decade; this one is a free local install that opens offline, and it says plainly it is about halfway to real work.

Restarted

A complete fake startup site, team photos and pricing, on every reload

Reading its generated pricing table and team row next to your own is a fast, uncomfortable check on how much of your landing page actually says anything.

It replaces the fiddly Word or Photoshop session it takes to fit passport photos or labels on one page, and nothing is uploaded.

Sumi.css

One 6.7 KB stylesheet that makes plain HTML look finished

When a docs page, internal tool or prototype needs to look decent today, you can link one file and write ordinary HTML, with no build step and no class names to learn.

Overscan

Ambient light for your desk, painted onto the monitors you already own

If you have spare monitors beside your main one, it turns them into an ambient backlight for films and games, free and with no hardware.

Dieline Studio

Free print-ready dielines for bags, pouches and boxes, sized in the browser

A small brand can get a correct cutting template for its box or pouch in a minute, instead of paying a designer or wrestling a template in Illustrator.

Moodi

A small 3D mascot that shows your interface is busy, thinking or done

It gives an AI product's waiting moments some personality without hiring an illustrator or building a Lottie pipeline.

Five Hundred Clocks

A gallery of 500 working clocks, each telling the time a different way

It is a concrete, browsable measure of how much range one frontier model has when asked for the same small thing again and again.

hangul.ink

Type Korean and watch a neural network draw it stroke by stroke, like a pen

A clear, playable example of a small handwriting model done well, and a reminder that a narrow, lovingly made demo can beat a general one.

SolidCraft

Parametric CAD in Rust for desktop, browser and AI agents, MIT or Apache

Anyone who has outgrown FreeCAD's quirks but will not pay for SolidWorks now has a permissively licensed option that an agent can drive over MCP.

EffectCraft

Keyframes, 306 effects and a render queue in a free native app

Motion graphics is the last thing a small studio still rents Adobe for, and this one speaks Lottie in and out rather than locking work in a private format.

Anatomy

An agent skill that draws your system as a machine you can take apart

Explaining an architecture well usually means hiring an illustrator for a week; this hands the job to the agent that is already reading the code.

ilove3d

Mesh repair, conversion and generators, all inside the tab

Nothing is uploaded, so you can run a client's scan through repair or decimation without the file leaving the laptop.
