Prompt Queue for Forge Neo: queue many generations, like ComfyUI
Forge Neo makes one picture job at a time. While it works, you wait. ComfyUI lets you queue up job after job, and we wanted the same in Forge. So we made Prompt Queue, a small free extension for Forge Neo. Press Add to queue next to Generate, change the page, and press it again. The jobs run one after another in the background.
What it does. Add to queue saves every setting on the page at that moment: prompt, size, seed, sampler, hires fix, the options of your other extensions, and on img2img the input pictures. Change the page at once and queue the next job. A copies box next to the button queues the same job many times; with seed -1 every copy gets its own seed. Ctrl+Shift+Enter adds to the queue too.
The queue panel. The Queue button at the bottom right (or Alt+Q) opens the panel. You see each job with its progress, time left and a live preview. Pause or resume the queue, stop the running job, drag waiting jobs into a new order, or press Run next. Remove a job or clear the list; every removal has Undo. Finished jobs show their pictures. Run again or Retry uses the exact same settings, and Load settings puts a finished job's settings back on the page.
The Auto box. Next to Add to queue is an Auto tick box. Ticked: jobs start by themselves. Not ticked: jobs wait until you press Resume, so you can line up a whole batch first.
Your pictures. A queued job shows in the normal gallery, the same as Generate: progress bar and live preview while it runs, then the pictures and their info text. Forge saves them to your normal output folder. Each job also remembers the model it was queued with and loads it when it runs.
Safe with Generate. A job you queue waits behind a Generate you press yourself, and the other way round. Two jobs never run at the same time. The queue keeps its jobs after a page reload and after a Forge restart.
Install. In Forge, open Extensions, then Install from URL, and paste the GitHub link. Or put the extension folder in Forge's extensions folder. Close Forge fully and start it again. The Add to queue button shows next to Generate on txt2img and img2img.
Tested on. Forge Neo 2.29 (the neo branch), in daily use since October 2026. Forge Neo neo-2.30.1 (the neo branch, 21 October 2026): 5 queued jobs ran one after another and landed in the gallery, with no errors.
If Forge Neo adds a queue itself. Today Forge Neo has no queue like this. If a later version adds one, you can keep the extension or remove it. If the two clash, remove this extension's folder. If you keep your current Forge, keep the extension. It keeps working.
Good to know. If you add, remove or update an extension after you queue a job, the page layout changes and old waiting jobs cannot be read. They fail with a clear message; queue them again. The queue has no login of its own, the same as Forge itself, so do not open Forge to an untrusted network.
Licence. The extension is free and open (MIT).
