USE CASE

Built for prototypes

Give every mock account a stable visual identity without uploading files or storing generated assets.

No account, API key, database, or client-side image renderer is required. Use the generated URL anywhere an image URL is accepted.

DOCUMENTATION

Change a query parameter, refresh the preview, and reuse the URL in HTML, Markdown, CSS, or React.

FAQ

Will an avatar change after reload?

No. The seed is hashed locally, so the same seed and settings always produce the same image.

What is the default size?

The query form /avatar?seed=... defaults to 512×512. The legacy /avatar/:seed form remains 256×256 by default.
