Flagid is a site for browsing and identifying flags from around the world. Filters allow searching by shape, colors, divisions and geographic regions, and multiple criteria can be combined. It also offers a flag game and a Flag of the Day feature.
FontStruct is a free font-building tool funded by advertising and sponsors. Users create fonts from geometrical shapes with the FontStructor editor, which generates TrueType fonts for download. Creations can be kept private or shared in a gallery, where other users' fonts can be downloaded or cloned for variations.
FreeCAD is an open-source parametric 3D modeler for designing real-life objects of any size. It allows sketches of constrained 2D shapes as a base for building other objects. It is multiplatform and reads and writes many file formats. It is used for product design, mechanical engineering and architecture.
FreeMapTools is a free online collection of map-based tools. Popular tools let visitors draw a radius around a point, measure distances between points, calculate the straight-line distance between two locations, and measure the area of a drawn shape. Results are shown in units including kilometers, miles, nautical miles, and acres.
A free interactive fretboard app for guitar that lets users look up scales and chords in CAGED, 3nps and other shapes. It shows scale positions and offers play-along with handpicked jam tracks, with a metronome.
Galaxy Zoo is a Zooniverse volunteer project where participants classify telescope images of distant galaxies by shape to help astronomers understand galaxy formation. Early data from the Vera C. Rubin Observatory is shown in the Rubin workflow. Volunteers' classifications are backed up by the work of others.
Genetic Cars 2 is an HTML5 web simulation that uses a simple genetic algorithm to evolve random two-wheeled shapes into functional cars over successive generations. It uses the box2d physics engine, includes configurable simulation parameters such as mutation rate and gravity settings, and offers a separate LEGO brick-themed variant. Users can save and restore population data and view replays of top-performing cars.
A browser-based simulation that uses neuroevolution to evolve car shapes and the neural networks that control them. Each car has a simple neural network improved through generations without backpropagation. It is based on BoxCar2D and rewritten from scratch using the Box2D physics engine. Controls include mutation rate and size, gravity and elite clones.
Geometrize is a desktop application and open source toolkit that recreates images as abstract arrangements of rectangles, triangles and ellipses. It generates thousands of random shapes and repeatedly mutates them using hillclimbing optimization, keeping only the best-fitting ones. It is available for Windows, Mac and Linux.
S2 is a Go library for spherical geometry. It provides representations of angles, intervals, latitude-longitude points and unit vectors, geometric shapes over the unit sphere such as caps, rectangles, polylines and polygons, a hierarchical cell decomposition, constructive operations and predicates, in-memory indexing, distance algorithms and snapping and simplification. Planar geometry and conversions to common GIS formats are outside its scope.
GrowVeg offers garden planning apps intended to help people grow fruit and vegetables in gardens of various sizes, shapes and styles. The site also provides a garden journal, gardening guides and how-to videos.
GuitarScale.org is a website that presents music scales for guitar and bass guitar through diagrams and supplementary information. Scales are shown in octave-based, shape-based and full fretboard diagram styles, with collapsible panels covering scale degrees, related chords and theory. The site states it shows no ads and offers ebooks for support.
iconmonstr is a source of simple icons run by one creator. The site states it offers 4784 free icons in 316 collections, available as SVG and PNG. Icons come in fill and outline versions, designed on a 24-pixel grid, with an icon generator for size, color and background shape.
Inkarnate is an online tool for creating fantasy maps, including world, regional and city maps for games and fantasy books. Its site lists line and shape tools, high-resolution exports up to 8K, cloneable user maps and a library of assets.
Layoutit Voxels is a CSS voxel editor powered by CSS grid and 3D transforms. It allows users to build models with HTML cuboids, choosing from shape options including cube, slab, wedge and spike, with palettes and textures. The page displays rows, columns, depth and a count of voxels, facets and size.
An interactive map that explores the tales behind cartographic myths, blunders and imaginations that shaped views of the world. The site offers projections including Arctic, Antarctic, Mercator, Pacific, Robinson and Mollweide.
A decentralized search engine and automated press review tool shaped as a WebExtension browser addon. Searches are keyword driven with selectable sources, and searches can be scheduled and exported. The search and sort job is handled by the extension on the user's computer, with no central server involved.
Minecraft Generator is a free hub of Minecraft generator tools. It offers generators for pixel circles, spheres, pixel art, torus shapes, 3D models, commands, armor trims, fonts, and seeds. No signup is required.
Natural Earth provides free vector and raster map data at 1:10m, 1:50m, and 1:110m scales, developed as a resource for making custom maps. Vector data comes in ESRI shapefile format and raster data in TIFF format, both using the WGS84 datum. Attributes include ranked feature names and map design details such as river width and country colors.
NDScala is a Scala 3 library for N-dimensional and multi-dimensional arrays (tensors), described as comparable to NumPy ndarray or PyTorch Tensor, with type safety over shapes, array and axis labels and numeric data types. The repository includes materials on shape-safe neural network training and an ONNXScala component.
NotebookCast is a free online collaborative whiteboard that does not require signup to start using. It supports real-time multi-user drawing, includes built-in time-unlimited audio and video calls, and provides tools such as shape drawing, sticky notes, text editing, and screen sharing. Users can create reusable whiteboard templates, access night mode, and share whiteboards via links. A free registered account allows saving whiteboards to a personal dashboard, and the tool works on any modern browser.
NZSL Online is the online dictionary of New Zealand Sign Language. It offers multimedia, multilingual entries that can be explored by English or Māori keyword search or by visual search using hand shape and body location, and it covers topics including the fingerspelling alphabet, numbers and classifiers.
Online Photo Editor is a browser-based photo editing tool on PhotoEditor.com. It supports cropping, resizing, rotating, flipping, blurring, sharpening, filters, effects, frames, text and shapes, and processes edits in the browser without uploading the image.
