About SimonOS
Small tools, clear workflows.
SimonOS is a calm utility launchpad for browser-based work: convert values, clean text, prepare files, inspect payloads, and keep moving without accounts or maze-like dashboards.
Local-first
Most tools run directly in the browser. Files and typed values stay on your device unless a page clearly says otherwise.
No account wall
The launchpad is designed for quick use: open a tool, do the job, copy or download the result, and leave.
Built in public
Tool requests and bug reports feed the roadmap, so the next utilities can follow real workflows instead of guesswork.
What belongs here
SimonOS is strongest when a tool has a simple input, a predictable transformation, and a useful output. Good fits include encoders, converters, validators, formatters, document helpers, and local file utilities.
The goal is not to become a giant dashboard. The goal is to keep adding small, reliable browser tools that feel ready when you need them.
