Why people look for a Komiko alternative
Komiko positions itself as an all-in-one anime toolbox: image generation, manga panels, line art coloring, upscaling, and video. The breadth is real — but every tool is fairly shallow, and its video generation is an aggregator of third-party models rather than a purpose-built pipeline.
If your goal is a coherent anime short — same characters, connected scenes, actual story — a toolbox of loosely related utilities isn't the same as a studio.
