"I was paying $95/month for RunwayML. This does more, runs locally, costs $49 once. I did the maths in ten seconds. No regrets."
"The ComfyUI JSON import alone is worth $49. I dragged in my entire Civitai folder and now my workflows are local and API production-ready."
"Offline at midnight. Cloud was down. Promptus ran. Deadline met. That's what owning your tools actually feels like."
"Finally own my tools instead of renting them. Should have done this months ago."
"I had 20 ComfyUI workflows sitting unused. I dragged them in, they all ran. I haven't opened a terminal since."
"The local API export turned my workflow into a product in one afternoon. I haven't looked back."

Everything about
Promptus vs Comfy Cloud.
Comfy Cloud is ComfyUI's hosted subscription at $20–$99/month. Your data is cloud-processed and the cost recurs monthly. Promptus runs the same workflows on your own GPU — offline, private, unlimited — for $49 once. Year one: Comfy Cloud costs $240–$1,188, Promptus costs $49. Year two: Comfy Cloud costs another $240–$1,188, Promptus still costs $49.
Yes — Comfy Cloud is the official paid, hosted version of ComfyUI at $20–$99/month. It runs your workflows on ComfyUI's servers without a GPU. Promptus is the local alternative: ComfyUI workflows on your own hardware, one-time $49 payment, no cloud, no subscription.
Yes. CosyUI accepts any valid ComfyUI JSON workflow file. Drag it in, CosyUI parses the node graph and flags anything missing. Missing nodes or models install with one click. Workflows from Civitai, GitHub, Discord, or your own archive all work without modification. Typical time from drag to first generation: under 3 minutes.
Yes, on the desktop app. Once Promptus and your models are downloaded, no internet connection is required. Your prompts, inputs, and outputs never leave your machine — not logged, not cached, not used for training. Promptus Web, the browser version, does require a connection.
Yes. Pay $49 once and own Promptus permanently — no monthly fees, no annual renewal. That payment includes 12 months of model updates, new CosyTemplates, and CosyUI improvements. After 12 months the app keeps working exactly as it is; only new updates require a renewal. Compare with Comfy Cloud at $240–$1,188/year or RunwayML at $1,140/year.
Promptus runs on Windows and macOS as a desktop app, and in the browser via Promptus Web. On Windows, local generation needs an NVIDIA GPU with at least 6GB VRAM for image workflows, and 12GB+ VRAM is recommended for video models like Wan 2.1. CosyTemplates are tagged with GPU requirements so you know before running.
