What is signmaker?

Sign Maker is a browser-based tool for designing wayfinding signage, built entirely with HTML and JavaScript. Wayfinding signage refers to the directional signs found in transit stations, airports, and public buildings that guide people through a space. The README is written in both Chinese and English. It currently works on desktop browsers only. The design interface is modeled on the component-based workflow popularized by tools like Figma. You build signs by placing and arranging predefined components on a canvas, and adjust their properties through a side panel. The tool adds visual realism by simulating lighting and overhead hanger effects, so the output looks closer to how a physical sign would appear in an actual installation. Completed signs can be exported as PNG image files or as SVG vector files that preserve crisp edges at any size. The project is still in active development. The roadmap listed in the README includes adding more signage component types for different zones, support for custom colors, fonts, and font weights, a preset signs system for quickly laying out standard sign configurations, and mobile support. A planned add-on system would allow creating sign styles for specific transit networks. The author notes the Chongqing rail transit GK standard as one reference for default styles, and mentions future add-ons for other subway systems. The README includes a candid note from the author warning that the source code is poorly written before forking. No installation is needed beyond opening the HTML file in a browser.
