Fattly vs Runway at a glance
Runway is one of the best-known AI video tools, popular with creators and filmmakers for high-quality generative video. Fattly is an all-in-one AI content platform where video sits next to image, voice and UGC. They overlap on AI video but solve slightly different problems — so the right pick depends on what you actually need to ship.
Where Runway is strong
Runway built its name on creative, cinematic video generation and a set of pro editing tools. If your work is pure high-end video — film-style shots, VFX-leaning experiments, motion work — it is a specialist that many creators reach for first. It is a genuinely capable tool at what it focuses on.
Where Fattly is different
Fattly generates video with sound built in — via the Veo 3.1 family, which produces dialogue, ambience and effects in one pass — and it works natively in Polish, German and Spanish, not only English. Beyond video, the same account gives you image generation, voiceovers, avatars, UGC ads and try-on, with 50+ AI models in one place, so a whole campaign lives under one login.
Pricing: subscription vs pay-per-credit
The pricing models differ. Runway is subscription-based. Fattly is pay-per-credit — you buy what you use, credits never expire, and there is no mandatory subscription, which suits people who create in bursts rather than every single day.
| Runway | Fattly | |
|---|---|---|
| Focus | Specialist AI video | All-in-one: image, video, voice, UGC |
| Sound in video | Added separately | Generated with the video (Veo 3.1) |
| Languages | English-first | Polish, German, Spanish, English |
| Models | Its own engines | 50+ models in one place |
| Pricing | Subscription | Pay per credit, credits never expire |
| Best if | Pure high-end video | Video plus everything in one place |
Which should you pick?
If you only need pure creative video and want to live inside a dedicated video tool, Runway is a strong, focused choice. If you want video that comes with sound, works in your language, and sits next to your images, voiceovers and ads with credits that never expire, Fattly is built for that. Plenty of people use a specialist for one thing and an all-in-one for the rest — the honest question is which describes your workflow.
