knotter

knotter lets you draw and refine interlace patterns on a Linux desktop, turning crossing lines into organized knot designs. Its editor is built specifically for constructing knot diagrams, so the central task is arranging and adjusting the interwoven paths that make up a pattern. This gives users a focused way to work on designs that would be difficult to plan accurately with ordinary drawing software.

Finished knot drawings can be exported as SVG files for scalable artwork and further editing in vector applications. They can also be rendered as raster images when a pixel-based file is more suitable for sharing, layout work, or other graphics tasks. The two export forms let the same design serve both production-quality illustration and everyday image use.

knotter is suited to artists, pattern designers, and anyone studying or creating interlaced knot artwork, from exploratory sketches to prepared graphics. It is especially useful when the structure of the crossings matters as much as the visual appearance, because the program keeps knot construction at the center of the workflow. The software runs on Linux and is open-source, with no other system, account, subscription, hardware, or companion-software requirements specified.
