【Freedom from OS constraints, a liberated workspace】
SF-OS is a browser-based pseudo-desktop environment built entirely with HTML/JavaScript. It alleviates concerns during the OS migration period following Windows 10 support ending, providing an environment where you can immediately access "your usual tools" on any device.
■ Three distinctive features of SF-OS
Overwhelming number of tools: Over 260 built-in tools solve everyday "quick tasks" including image conversion, MD editor, PDF editing, simple LLM, retro games, and more.
Reassuring privacy design: Most tools operate "entirely within the browser." Data is never sent to external servers, allowing you to safely process highly confidential files.
Lightning-fast & lightweight: No installation or user registration required. Simply access the URL and it runs smoothly even on low-spec PCs and Chromebooks.
■ Recommended for those who:
Want to complete work without installing software
Are searching for Windows software alternatives on Chromebook, Linux, etc.
Prioritize security and want to process data locally
Experience the ultimate versatility and speed made possible precisely because it's a "facade."
