No. Manga Editor Desu runs in a web browser with no installation and no account. Open the page and start working. It can optionally be installed as a standalone application through the browser's own install prompt, and it also runs from a local copy opened directly from disk.
Yes. Every editing feature works on its own: panel layouts, speech bubbles, text, fonts, screentones, pens, filters, blend modes, layers and export. AI generation is optional and requires a backend that you supply and configure yourself.
Nothing. It is free and open source under the GNU General Public License v3.0. If you use a paid cloud AI service such as Fal.ai or Grok, that service bills you directly.
Saving a project produces a single LZ4-compressed file named DESU-Project.lz4, downloaded to your computer. Loading accepts both .lz4 and .zip project files. Projects are not saved to any server.
Set the page size in millimetres and the download DPI, which defaults to 300, then use Image Download. The exported PNG resolution is calculated from the page size and the DPI, and the paper orientation follows the canvas. Pages can also be exported as SVG.
No. Undo history is kept per page and is cleared when you switch or load a page. Within a single page there is no step limit on undo and redo.
Six services are supported: ComfyUI running locally, ComfyUI running on RunPod, SD WebUI (AUTOMATIC1111 or Forge), Fal.ai, Grok from xAI, and Ollama. ComfyUI, SD WebUI and Ollama run on your own machine; RunPod, Fal.ai and Grok are cloud services. Each task type can be routed to a different service independently. Inpainting and angle regeneration require ComfyUI.
Almost always because the backend has not been told to accept browser requests. ComfyUI needs --enable-cors-header. SD WebUI and Forge need --api --cors-allow-origins *, and Forge additionally needs a small source patch. Ollama needs the OLLAMA_ORIGINS environment variable set before it is restarted. Also check that the URL is right, that the backend is actually running, and try 127.0.0.1 instead of localhost.
Full instructions are in the AI backend setup guide.
Yes. Workflows exported from ComfyUI in API format can be imported, assigned a task type, and enabled one per type. Node inputs are editable inside the editor, with model, LoRA, sampler and VAE lists read from your running ComfyUI server. Local ComfyUI and RunPod ComfyUI keep separate workflow sets.
Interface language, tool and canvas settings, AI connection settings including API keys, and saved prompt sets are kept in browser local storage. Imported ComfyUI workflows, uploaded fonts, auto-saved projects and usage statistics are kept in IndexedDB.
The editor has no server of its own, and your projects are never uploaded by the application. Two things do leave your machine.
First, the site uses Google Analytics, so page views and interface interactions are recorded.
Second, if you configure a cloud AI service — RunPod, Fal.ai or Grok — then the prompts, story or dialogue text and panel images involved in those requests are sent to that service. Using only ComfyUI, SD WebUI or Ollama on your own machine keeps generation local.
Page loads also fetch fonts and a small number of assets from Google Fonts, cdnjs and unpkg.
Use Settings Reset in the application, which lists exactly what will be deleted before proceeding. Alternatively use your browser's clear-site-data feature.
Yes. Static assets are cached by a service worker after the first visit, and the editor can be installed as a standalone application. It also runs from a downloaded copy opened directly from disk. Cloud AI services naturally require a connection.
