QR codes, password generation, a regex tester, and more — meet Nova Tools
Nova Tools gathers the small utilities you occasionally need — but never enough to install an app for — in one place. Everything runs in your browser.
The tools
- QR code generator: create a QR code from a URL or text
- Password generator: random passwords with configurable length and character sets
- UUID generator: mint UUIDs on the spot
- JSON formatter: turn mangled JSON into something readable
- Timestamp converter: UNIX timestamp ⇔ human-readable date
- Color converter: convert between HEX, RGB, HSL, and other color formats
- Regex tester: try patterns live and inspect the matches
- Character counter: count characters and lines
- Directory tree: build a plain-text tree diagram of a folder structure
How to use it
Just pick a tool from the list on the top page. No sign-up, no installation.
Privacy
Everything runs in your browser — nothing you type is sent to a server. Generated passwords never leave your machine. All features are free.
When it comes in handy
- Whipping up a QR code for an event
- Formatting a one-line JSON blob from an API log so you can actually read it
- Building a folder-structure diagram for a README
Novare Orbis offers other free, browser-based tools as well — see the full list.
