About CodexValley
CodexValley is a growing set of practical online tools for everyday work. We start with people who sell online, then students and applicants, and add more areas as real demand shows up.
The idea is simple: instead of one-off calculators that stop at a number, each workspace takes a job from start to finish, from your details or files to a result you can use.
How we work
- Free core tools. The tools you need most stay free to use.
- Private by design. File tools are built to run in your browser so your photos, documents and spreadsheets are not uploaded.
- Sources and dates. Fee and rate presets show where they came from and when they were last checked, and you can change every value.
- Clear limits. Our tools give estimates for planning. They are not financial, tax, legal, engineering or medical advice.
Where we are
CodexValley is new. Every tool on the site works today, in your browser, with no account. We began with online sellers and have added calculators for property, construction, food, fashion and everyday life, plus a few developer tools. We add more where people tell us they need them, so if something is missing, send us a note.
