Free generators for websites, security, business and test data
Most of these tools answer the same need: you want something made properly, quickly, without signing up or uploading anything. The QR Code Generator makes static codes for links, emails, calls, texts and map locations that never expire. The Wi-Fi QR Code Generator prints a scan-to-join card for guests, the vCard QR Generator puts your contact details on a business card, and the Bulk QR Code Generator turns a spreadsheet into hundreds of named codes. For products and labels, the Barcode Generator works out EAN-13, UPC-A and ITF-14 check digits for you.
For security, the Random Password Generator and Diceware Passphrase Generator use your browser’s cryptographic random generator, and the UUID Generator makes time-ordered version 7 IDs for databases. Web builders can write a robots.txt that blocks AI training crawlers, a sitemap.xml, meta tags with search and share previews, a matching share image, a full set of favicons and an .htaccess file that redirects in one hop.
Developers and testers can fill a database with the UK Fake Data Generator, whose phone numbers and emails are reserved so they can’t reach a real person, and check a checkout with test card numbers. For new businesses, there are ideas from the Business Name Generator and Slogan Generator, and batches of single-use discount codes from the Coupon Code Generator. Everything runs in your browser, so lists, passwords and data never leave your device.
Questions and answers
- Should I use the Random Password Generator or the Diceware Passphrase Generator?
- Both are secure. A random password such as
q7#Lx…packs the most strength into the fewest characters, which suits passwords you store in a password manager and never type. A Diceware passphrase of six random words is about as strong as a 12-character random password but far easier to type and remember, so it’s the better choice for a password manager’s master password, your computer login or Wi-Fi. - What’s the difference between the QR Code, Wi-Fi QR and vCard QR generators?
- They make the same kind of code but put different instructions in it. A normal QR code holds a link or text. A Wi-Fi code holds your network name and password in a format phones recognise, so scanning it joins the network. A vCard code holds contact details, so scanning it offers to save a new contact. Use the Bulk QR Code Generator when you need many codes at once.
- Do these QR codes expire?
- No. They’re static codes: the content is stored in the pattern itself rather than in a redirect on someone’s server, so they keep working for as long as the link or details inside them do. The flip side is that a printed code can’t be edited, so test it before printing a batch.
- Is the fake data safe to use in testing?
- Yes, that’s what it’s designed for. Phone numbers come from the ranges Ofcom reserves for drama and fiction, emails use example.com, example.org and example.net, which are reserved and never deliver, and National Insurance numbers use the QQ prefix that HMRC never issues. Postcodes have the right format and area but are made up, so treat them as test addresses only.
- Why doesn’t the test card tool make random card numbers?
- A random number in a real card range could belong to a real person’s card. Payment providers publish specific numbers that only work in test mode, so the tool lists those, including cards that are declined or ask for 3D Secure, and checks the format of any number with the Luhn algorithm.
