RoomGPT
Open-source enough to clone and run yourself for free — or just pay per credit with no subscription, no card required to start.
What is RoomGPT?
RoomGPT is one of the few genuinely open-source tools in this entire category — the original codebase (Nutlope/roomGPT on GitHub) is public, letting a developer clone it, plug in their own Replicate API key, and deploy a self-hosted version for free. Most people, though, use the hosted version at RoomGPT.io, which runs on the ControlNet machine learning model and works exactly the way its early viral popularity suggested it should: upload a photo of a room, pick a style, and get a redesigned version back in seconds, with no account setup complexity. That simplicity, more than any specific feature, is why it built genuine brand recognition — reportedly more than 4 million users — well before most of its current competitors existed.
The business model is also a real point of difference: rather than a monthly subscription, RoomGPT.io charges per credit, purchased in packs starting around $9, so occasional users pay only for what they generate rather than committing to an ongoing plan. New accounts get a single free credit to try it, though — not an ongoing free tier — and honestly, that's become the exact detail newer competitors point to when positioning against it. Independent 2026 comparisons consistently note that RoomGPT stops at the generate step: no edit mode to refine a result without spending another credit, no shoppable furniture links, no exterior or garden redesign, and no personalization quiz before generation. It remains interior-only, and increasingly it's the deliberately-simple starting point that newer, fuller tools compare themselves against rather than the other way around.
User figures and open-source status are drawn from RoomGPT's own GitHub repository and multiple independent reviews through mid-2026. Reported style counts and mobile app availability vary somewhat across sources — confirm current details directly at roomgpt.io.

Our verdict
RoomGPT's continued relevance says something honest about this category: sometimes the simplest possible version of an idea, done early and well, earns enough brand recognition to stay in the conversation years after fuller competitors arrive. Its open-source roots and pay-per-credit pricing remain genuinely appealing if you just want an occasional visualization without committing to a subscription, and the workflow itself is still about as frictionless as this kind of tool gets. But the honest comparison with 2026's newer entrants isn't close on features — no edit mode, no shoppable furniture, no exteriors — and RoomGPT increasingly reads as the baseline other tools measure themselves against rather than the one to beat. For a quick, cheap, one-off look at a room in a new style, it still does the job.
FAQ
Is RoomGPT free?
New accounts get one free credit to try it, but that's a one-time trial, not an ongoing free tier. Beyond that, you buy credit packs starting around $9, with no subscription required.
Is RoomGPT really open-source?
Yes, the original codebase (Nutlope/roomGPT) is publicly available on GitHub, and developers can clone it and deploy their own self-hosted version using their own Replicate API key.
Can I edit a RoomGPT result after generating it?
Not directly — RoomGPT stops at the generate step, so refining a result typically means spending another credit on a new generation rather than using a dedicated edit tool.
Does RoomGPT redesign exteriors or gardens?
No, it remains focused on interior rooms only — living rooms, bedrooms, kitchens, bathrooms, and home offices — unlike some newer competitors that also cover exteriors and gardens.
Does RoomGPT link to shoppable furniture?
No, it generates a visual redesign without connecting you to real, purchasable products, which some competitors now offer as a distinct feature.
Do I need a subscription to use RoomGPT?
No, its hosted version at RoomGPT.io runs on a pay-per-credit model, so you only pay for the redesigns you actually generate rather than committing to a recurring plan.
