RunDiffusion
Cloud workspace bundling Stable Diffusion, Flux, ComfyUI and a dozen other image/video models behind one subscription.
Pick RunDiffusion if you want pro-grade Stable Diffusion, Flux and video models in one billable workspace without renting a GPU or stitching tools together.
Skip it if you already run ComfyUI locally on capable hardware or only need one specific model that has its own cheaper subscription.
RunDiffusion is a hosted creative platform that gives you on-demand access to the open-source AI image and video stack — ComfyUI, Automatic1111, Fooocus, Kohya for training — plus a Runnit front-end that wraps a marketplace of commercial models (Flux Pro Ultra, Veo 3.1, Kling 2.5, Seedance, Seedream, LTX-2, Juggernaut variants, Gemini and OpenAI image endpoints). Instead of paying for a GPU rig or juggling separate Midjourney, Runway and ComfyUI subscriptions, you spin up a session in the browser and pay for compute time or token credits.
It is aimed at working creatives — concept artists, ad agencies, gaming and fashion teams — who want SDXL/Flux power without the DevOps. Pricing starts free with 100 daily tokens, then Runnit Hobby ($8.79/mo) and Pro ($23.99/mo); the Creators Club + Pro tier ($41.79/mo) unlocks API access and the long-running ComfyUI/A1111 servers, and Team and Enterprise plans add seats, governance and custom SLAs. Commercial licenses are bundled, which is a real advantage over chaining together free model weights.
The catch is that you are renting compute, not owning it: heavy ComfyUI users with a 4090 at home will save money self-hosting, and the marketplace model selection changes faster than any documentation can. But for teams who need legally-clean output across many models in one bill, it is one of the most complete options on the market.
The clearest 'all the open-source image tools, hosted properly' play in the market, with a smart pivot into commercial video models via Runnit. The pricing is fair until you become a power user, at which point a home GPU starts to win on unit economics — but the bundled commercial licensing keeps it sticky for agencies.
