About

Generate alien names for science fiction, tabletop RPGs (Stars Without Number, Lancer, Traveller), and worldbuilding. Each of the three styles uses its own syllable pool tuned to a body plan. Grey style is vowel-heavy and melodic (Aelura, Zharin, Oonash), fitting humanoid aliens, telepaths, and ancient races. Insectoid uses hard consonant clusters and occasional apostrophes (K'tek, Zzrack, Tk'klar), fitting hive-mind species, drones, and chitin-armored xenos. Reptilian uses sibilants and long vowels (Sssarith, Vasshar, Tessik), fitting saurian races, snake-folk, and predator species. About 60 % of names use a 3-part syllable (opener + middle + closer); the rest are shorter 2-part forms for variety. Combination space exceeds 100K per style — each click produces effectively unique names.

FAQ

Do these names work for D&D outer-planar creatures?
Yes, especially the Grey style for celestials and Reptilian for serpentine races (yuan-ti, sahuagin variants). Insectoid fits thri-kreen and formian outsiders.
Why do insectoid names have apostrophes?
Apostrophes signal a click or glottal stop in fiction — a common convention for non-humanoid speech. Drop them if you prefer cleaner output.
Can I use these in published fiction?
Yes. All names are algorithmically synthesized and not copied from any specific franchise.
How long should an alien name be?
Most generated names are 6-12 characters. The 3-part syllable mode produces longer "official" names; the 2-part mode is closer to short conversational handles.
