Decker, a platform that builds on the legacy of Hypercard and classic macOS
Points and comments are a snapshot, not live.
Decker is a multimedia platform for creating interactive documents, inspired by HyperCard and classic MacOS.
Decker lets users create interactive documents with sound, images, hypertext, and scripting. It runs in browsers and natively on MacOS, Windows, BSD, and Linux. Decks can be saved as standalone HTML files. It includes a scripting language called Lil, influenced by Lua and Q. Built-in widgets and custom widgets are supported. Decker is open-source under the MIT license. It features a ditherpunk aesthetic, no telemetry, and supports headless use via Lilt. Libraries include plotting, pathfinding, and PDF export.
What commenters are saying
Commenters appreciate Decker as a modern HyperCard revival, noting its scripting language and ease of use. Some find the retro aesthetic limiting for modern presentations. One user noted font size adjustment is limited to fixed-size bitmaps, though libraries offer vector fonts. A user criticized the 1-bit aesthetic for limiting broad appeal, but others countered that many projects exist on itch.io, including a Steam game. The thread references past discussions and compares Decker to tools like tldraw and Marimo.
