Dummy content for development

Filler text, placeholder images, initials avatars, fake JSON & CSV fixtures, multi-page sample PDFs and HTTP testing helpers. No sign-up — plain GET URLs you can paste straight into your markup and mocks.

Filler text

Neutral paragraphs for layouts: they read like real copy without distracting anyone with meaning.

Language Paragraphs wrap in <p>

Placeholder images

SVG renders the label in any alphabet; PNG/WebP/JPG are raster (label is Latin-only).

640×360 800×600 1200×630 (og) 1920×480 400×400 150×150

Width Height Format Background Text color Label

Initials avatars

Deterministic SVG avatars from a name — same name, same color, any alphabet.

Data fixtures

Fake entities for API mocks, seeds and import testing: users, posts, products, comments — as JSON or CSV.

Sample PDFs

Multi-page PDF documents filled with filler text — for upload forms, viewers and print flows. Latin text only (built-in Helvetica).

Pages Language Title Seed (opt.)

HTTP testing

Echo any status code or delay a response — handy for error states, retries and timeout handling.

Status code Delay, seconds

API

Every tool is a plain GET endpoint, no auth. Pass seed to make the output reproducible.
