Why Use Browser-Based Generators?
Especially for secrets — the server should never be in the path.
A web-based generator that runs in JavaScript can produce passwords, passphrases, and random
identifiers without ever transmitting them over the network. The page is delivered as static files; the random
number generator inside your browser (via crypto.getRandomValues) is the same family of API
modern browsers use for real security work, not a toy PRNG. That is the right foundation when you are standing up
credentials, recovery codes, or anything that would be a disaster if leaked.
Speed and reliability follow: no queue on a server, no rate limit, no “subscribe to export.” You can refresh as often as you like, tweak length and character types, and copy the result in milliseconds. If you are on a plane or an isolated network, cached assets still run — no API key, no account cookie required for the core experience.
DoItSwift is built for people who are tired of lead-magnet tools that push a paid product the moment a password appears. We do not collect what you generate, do not store it in a database, and do not A/B-test your passphrases. The trade-off is the usual one for static sites: you are responsible for saving the output in a password manager or other secure place before you leave the page.
This hub will grow with QR, UUID, barcode, and layout helpers. Each will follow the same default: run locally, disclose what happens in the UI, and avoid opt-out uploads. When a future tool must call the network, we will say so in plain text before you use it.

Generator hub FAQ
Are these generators secure?
For sensitive outputs (passwords, passphrases, future UUID and random tokens), DoItSwift uses the Web Crypto API (crypto.getRandomValues) in your browser, not weak pseudo-random functions. No generator sends your result to a server, so secrets do not pass through our infrastructure.
Is generated content stored anywhere?
We do not save generated values to a database or localStorage. What you see exists in page memory for your session and disappears when you close the tab. Save anything you need in your own password manager or file.
Do these tools work offline?
After the first load, static pages can run without a network. Random generation and QR-style tools (when they ship) use the same in-tab execution model. Some future tools may need a CDN for fonts; the hub itself stays usable offline for password generation once cached.
Are the generators cryptographically secure?
Passwords on DoItSwift use the same cryptographically strong random number generator the browser uses for TLS and other security features. This is a different class of randomness than Math.random() in JavaScript, which is not appropriate for security-sensitive uses.
Can I use these for commercial purposes?
You may use the tools to produce material for your business or product as long as you follow applicable laws. DoItSwift is not a substitute for legal, tax, or compliance review for generated documents when those launch.
How do I suggest a new generator?
Use the site contact form with a one-line use case. We look for in-browser, privacy-respecting ideas that do not require uploading user content to our servers by default.
