POMjs is a random password generator in HTML and pure Javascript. It can be customized by modifying the sources. There's really nothing magic going on here, but it works and is somewhat responsive. The goal was to make something small, useful, and reasonably free from dependencies.
Download the distribution or clone the repo. Files and folders should be placed in your web root, or another folder accessible to your web server. All references to CSS and Javascript use relative paths.
There may be references to "Öppet Moln" ("Open Cloud"), which is a Swedish site run by the author of POMjs, oppetmoln.se, to promote open source solutions for general use. You can, of course, delete such references.
I'd appreciate a mention on whatever website you use this one, and a link to the original repo, but it's not required.
Generate random phone numbers for all countries using the mobile phone generator. These numbers are fake, but they are built using the validations of telephone numbers.
A site which takes a totally legit copy of the ROM of Final Fantasy 1 for the original NES and lets you randomize many aspects of the game, including the type of game (regular, hunting for x of something, boss rush, boss battle types), whether or not the bugs in the original ROM are fixed, what's in the shops, and other things. You can supply a seed to the randomizer or let it pick its own. Then download the ROM, load it into an emulator, and see how you do.
Pyrgg is an easy-to-use synthetic random graph generator written in Python which supports various graph file formats including DIMACS .gr files. Pyrgg has the ability to generate graphs of different sizes and is designed to provide input files for broad range of graph-based research applications, including but not limited to testing, benchmarking and performance-analysis of graph processing frameworks. Pyrgg target audiences are computer scientists who study graph algorithms and graph processing frameworks.
An online server that generates different kinds of random data for testing and development - integers, sequences, phone numbers, credit card numbers, names... you name it, they generate it. Has a REST API, 1k hits/month, request a free API key.
Mimesis is a package for Python, which helps generate big volumes of fake data for a variety of purposes in a variety of languages. The fake data could be used to populate a testing database, create beautiful JSON and XML files, anonymize data taken from production and etc.
Generate test data, unique ids, passwords, vouchers or other randomized textual data very quickly using a template language. The template language is superficially similar to regular expressions but instead of defining how to match or capture strings, it defines how to generate randomized strings.
Pagan hashes input strings to generate unique avatar images intended for use as profile pictures in web applications. These images can be used to replace default user images for new accounts, or to enhance comment sections by visually representing a user's IP address or username as an 8-bit-like character sprite and not a random blob of pixels (ala the drunken bishop algorithm).
An open-source utility for Linux that uses an attached webcam to seed the kernel's random number generator for cryptographic purposes.
An open source utility for Linux that seeds the kernel's random number generator with data pulled from an attached microphone.
What if Friedrich Nietzsche wrote Bill Keane's comic strip Family Circus?
A command line utility that calculates the amount of informational entropy in arbitrary fields of data. Useful for cryptanalysis and data compression research
