As answered by people managing CodeLive Studio.cyou and LiveCode Platform.
CodeLive Studio.cyou's answer
CodeLive Studio is a free suite of 10 browser-based developer tools (HTML/CSS/JS playground, Python & SQL runners, JSON formatter, regex tester, Markdown editor, YAML formatter, diff checker, code screenshot tool) that require zero signup and process everything client-side. No account, no upload, no limits.
CodeLive Studio.cyou's answer
Most online code playgrounds force you to create an account just to save or share work. CodeLive Studio lets you open the tools, write code, run it, format JSON, test regex, or take code screenshots instantly — with no signup and everything running privately in your own browser.
CodeLive Studio.cyou's answer
Developers, students, teachers, and anyone who needs quick, private online tools for writing HTML/CSS/JS, running Python or SQL, formatting data, testing regular expressions, or generating clean code screenshots without creating an account.
CodeLive Studio.cyou's answer
Frontend and full-stack developers Computer science students and teachers Indie hackers and side-project builders Anyone who prefers privacy-first, no-signup developer tools
CodeLive Studio.cyou's answer
Pure client-side JavaScript WebAssembly (for Python runner and related tools) Browser-based code editors and sandboxed previews No server-side processing for the core tools
CodeLive Studio.cyou's answer
CodeLive Studio was built for the simple reason that basic developer tasks should not require signing up, waiting for cloud processing, or worrying about where your code is stored. It started as a private, no-account alternative to the usual online playgrounds and grew into a complete set of 10 free client-side tools.

His legacy still exists and continues today. Even updated to modern sensibilities, as well as cross-platform, and compatible with all your legacy Hypercard stacks! As far as I remember, progression was Hypercard -> Metacard -> Runtime... - Source: Hacker News / over 1 year ago
