A rebuilt generator that runs on your device. Faster, private, up to 100,000 rows without an account, and the same data every time with a seed.
RNDGen has been rebuilt from the ground up. The biggest change: data is generated in your browser, not on our servers.
What that means for you
- No waiting and no queue. Files are written as a stream, so even a million rows do not freeze the page.
- Private by design. What you generate never leaves your device.
- No sign-up wall. As a guest you get up to 100,000 rows per file with 20 fields, in every format.
Better data
- Fields that agree with each other. The email comes from the name, the age from the birthdate, the ZIP code from the state.
- More than 240 field types: people, addresses, companies, finance, internet, dates, products, vehicles, travel and QA edge cases.
- Repeatable. A seed and a reference date give exactly the same dataset on any day, and a share link opens the same schema for a colleague.
- More formats: CSV, Excel, JSON, JSON Lines, SQL for PostgreSQL, MySQL, SQLite and SQL Server, XML, YAML, Markdown and HTML.
Passwords, rebuilt
The password, passphrase and PIN generators now use crypto.getRandomValues, the browser’s cryptographic random source, and come with policy presets (NIST, PCI DSS, HIPAA, Active Directory and more) and export to TXT, CSV, JSON and Bitwarden.
