Überblick
Utility and generator tools act as the digital Swiss Army knife for everyday tasks. From QR codes and UUIDs to password checks and random data, this catalog provides fast, client-side helpers you can rely on during planning, development, or daily work.
Small tasks still need reliable tools
Teams repeatedly need quick outputs like IDs, random numbers, or configuration snippets. Without standardized utilities, these tasks become manual or inconsistent.
Security-related helpers like password checks or hashing need to be fast and trustworthy. Client-side processing reduces exposure of sensitive inputs.
Utility tasks are often urgent and time-bound, so the tools must be frictionless and easy to access.

Häufige Fragen
Are random values secure?
Many generators use cryptographic APIs for secure randomness.
Do you store generated outputs?
No. Outputs are generated locally and not saved.
Can I generate multiple UUIDs?
Yes. Generate as many as you need.
What is a BIP39 phrase?
It is a mnemonic seed phrase standard used for wallets and testing.
Are password checks private?
Yes. Analysis happens in your browser.
Is MD5 safe for security?
MD5 is not recommended for secure hashing but is useful for checksums.
Can I use QR codes commercially?
Yes. Outputs are free to use.
Do you validate user-agent strings?
The parser helps interpret, but validation depends on the source string.
