How DummyLogo generates placeholder logos
DummyLogo is a seeded SVG logo generator for fictional brands. It is built for mockups: you need something that looks like a company mark, and you need that mark to stay the same the next time the screen renders.
Definition
A DummyLogo is a square, self-contained SVG produced from a company name and optional controls (seed, variant, size, style). Letterforms are outlined as paths. The file does not require webfonts when you embed it. It is a placeholder, not a registered trademark and not a substitute for a designed identity.
Determinism
Generation is keyed by hash(name:variant:seed:sizeTier). The default seed is oak-7. Changing the pixel size inside the same tier (for example 256 → 512) keeps the composition; crossing a tier boundary can pick a layout that fits the new size.
Size tiers
- Icon · ≤64px
- Mark or monogram. Text is minimal or omitted so a 32px favicon stays readable.
- Compact · ≤128px
- Shortened labels, no descriptors. Useful for app icons and dense UI.
- Full · >128px
- Complete wordmarks, lockups, crests, and seals with optional industry descriptors.
Styles, marks, and type
Layout styles: mark, lockup, stacked, wordmark, badge, monogram, crest, seal, split. Auto selects among them from the seed. Industry words (Legal, Labs, Cafe, Capital) bias the mark set — 38 geometries in total. Type is drawn from 14 families (Montserrat, Playfair Display, Outfit, Space Grotesk, Cormorant Garamond, Syne, Archivo Black, Libre Baskerville, DM Sans, Bebas Neue, Cinzel, Manrope, Instrument Serif, Unbounded) and 23 palettes spanning luxury, tech, editorial, bold, and friendly vibes.
What DummyLogo is not
- Not a logo-for-hire service or AI image model that invents a new mark every request.
- Not a trademark clearance tool. Example names are fictional stand-ins.
- Not a raster placeholder like a gray box or Lorem Picsum photo.
