Identicon

A deterministic avatar from a hash. Same input, same face.

"randomly" → 1e0125772f4ab33a

This is the one generator here that does not use the seed. It reads sha256 of the input and nothing else, so pressing Generate will not change the picture — only editing the text above will. That is the point: the same string gives the same avatar on any machine, forever, with nothing stored anywhere.

[data-canvas-stage] { display: none; }

Drawn in the browser

This generator does not send you an image. The server sends a short description of one — the parameters below, plus a 32-byte key — and the drawing is done here, from the same byte stream the server would have used. That needs JavaScript, so with it switched off there is nothing to show.

The description itself is still public: /api/v1/g/images.identicon returns it, and the maths is in resources/js.

Seed receipt

Class A · Cryptographic

This generator is a pure function of what you typed. No randomness was drawn, and the same input will produce this same result anywhere, forever.

The token is the seed, so this link recomputes the result rather than looking it up. No database, and it works for as long as v1 does.

Input

Anything at all — a username, an email, a commit hash. This, and nothing else, decides what you get.

Size

Grid

3 9

A 5×5 grid mirrored down the middle needs only 15 bits, which is why identicons were 5×5 long before anyone had bits to spare.

Cell shape

Two tone

A second hue, 50° along, for roughly half the live cells.

Padding

Cell gap

0 0.4

Entropy source

Picking a source changes the story on the receipt, never the quality: anything below class A is mixed with the OS CSPRNG before it reaches you. This result actually came from No entropy used.

seed token YB17Z2Y12FR8FXMRZA58YK57M0

Re-render keeps this token. Generate replaces it. That is the whole idea.

Burned into the corner before the file is written, so the image keeps its provenance wherever it ends up:

This page and /api/v1/g/images.identicon run the same code. There is no private endpoint.
