This site draws randomness from 10 sources and builds words out of corpora it did not compile. Not one of them charges, not one of them asked for a key, and every one of them could have.

Where the randomness comes from
See them live →-
Operating System CSPRNG
Class AThe kernel of the machine that served this page
PHP’s random_bytes(), which is getrandom(2) on Linux. Nobody to credit and nobody to ask.
No third party involved www.php.net ↗
-
ANU Quantum Vacuum
Class AAustralian National University, Canberra
Vacuum field fluctuations measured by homodyne detection, published as bytes for anyone to use.
Free public API · attribution requested qrng.anu.edu.au ↗
-
RANDOM.ORG
Class ARandomness and Integrity Services Ltd., Dublin
Atmospheric radio noise, running since 1998. We watch the quota headers and stop when told to.
Free tier · daily quota, no key www.random.org ↗
-
NIST Randomness Beacon
Class BUS National Institute of Standards and Technology
NIST publishes the beacon; it does not endorse this or any other use of it.
US Government work · public domain beacon.nist.gov ↗
-
drand · League of Entropy
Class BThe League of Entropy — Protocol Labs, Cloudflare, EPFL, Kudelski and others
A threshold BLS signature nobody in the network could have produced alone.
Public endpoint · open network drand.love ↗
-
Bitcoin Proof-of-Work
Class Bmempool.space, reading the Bitcoin chain
The work is the network’s; the explorer is the part that answers our HTTP request, and it is the part that gets credited.
Open-source explorer · free public API mempool.space ↗
-
USGS Seismic Feed
Class CUSGS Earthquake Hazards Program
The whole hour of microquakes, not only the one the receipt names.
US Government work · public domain earthquake.usgs.gov ↗
-
NOAA Space Weather
Class CNOAA Space Weather Prediction Center
The planetary K-index, once a minute, from a service that exists to warn power grids.
US Government work · public domain www.swpc.noaa.gov ↗
-
Live Weather
Class COpen-Meteo
Live conditions at a city picked at random. Their free tier is generous and we cache hard so as not to abuse it.
Weather data CC BY 4.0 · free without a key open-meteo.com ↗
-
ISS Position
Class COpen Notify, by Nathan Bergey, from NASA tracking data
The station’s ground track. Worth two or three bits, and worth every one of them as a sentence.
Free public API open-notify.org ↗
Words, names and the data behind them
-
EFF Diceware wordlists
Electronic Frontier Foundation
7,776 and 1,296 words — 12.925 and 10.340 bits each. Bundled, not fetched, so the entropy accounting is verifiable offline.

-
Wikipedia article summaries
Wikipedia contributors, via the Wikimedia Foundation
Every article the words module quotes is linked back to its page, which is both the licence condition and the interesting part.
CC BY-SA 4.0 ↗
-
GBIF species records
GBIF Secretariat and the publishing institutions
Scientific names come with their naming authority attached, because in taxonomy the citation is part of the name.
Per dataset — CC0 or CC BY ↗

Syllable grammars and lorem vocabularies
Hand-built for this project
The classical lorem text descends from Cicero by way of a 15th-century typesetter, and is long out of copyright.
No third-party rights
The stack, and the letterforms
-
Laravel MIT
The framework.
-
Alpine.js MIT
Every interaction on this site, and no more than that.
-
Tailwind CSS MIT
The palette in §2 of the brand doc, as OKLCH tokens.
-
Vite MIT
The build.
-
Pest MIT
Including the tests that fail when this page tells a lie about a count.
-
KaTeX MIT
Typesets the equations module, in the browser.
-
Inter SIL OFL 1.1
Rasmus Andersson. Everything you are reading that is not a number.
-
JetBrains Mono SIL OFL 1.1
Every number, seed and hash — and every share card, which is drawn from the bundled TTF.
-
Bunny Fonts Service
Where the two faces above are fetched from at build time. They ship from this origin, not a tracker’s.
-
OpenStreetMap ODbL · © OpenStreetMap contributors
The map every ISS receipt links to as its proof.
Not credited, because not yet used
These are named in the specification for generators that have not been built. This site has never sent any of them a request. They are listed here so that the list above can be read as exactly what it is — everything currently in use — and so that the day one of them starts answering, it moves up a section rather than appearing out of nowhere.

Free does not mean uncredited.
Every service on this page could have put a login in front of itself and did not. A beacon run by a government laboratory, a quantum optics bench in Canberra, an earthquake feed maintained so that buildings do not fall down — all of it answers an anonymous HTTP request in under a second, for nothing.
The least this project can do in return is cache politely, time out quickly, name them on every result they touch, and keep this page honest about which of them it has actually asked for anything.
