Arcadium 3D vs RoomGPT

Arcadium 3D

Arcadium is a reasonable pick for someone who wants to sketch a floor plan or interior layout in 3D without installing CAD software, and the free tier is generous enough to test with a real project. The 30-object cap on the free plan will feel tight the moment a room gets furnished in any detail.

Pros

• +Runs entirely in-browser with no install required
• +Large furniture library (10,000+ models) plus custom model import on paid plans
• +Link sharing makes it easy to show a design to someone else
• +Free tier for students and teachers

Cons

• −Free plan's 30-object cap is restrictive for a fully furnished room
• −Paid pricing shown is the annual-billed rate; monthly-billed cost may be higher
• −No API or offline/desktop version

RoomGPT

The fastest way to answer "what would this room look like in a different style", and the no-expiry credit model suits people who use it twice a year rather than twice a day. Treat the output as a mood board, not something a contractor can build from.

Pros

• +Credits are a one-time purchase with no expiry, confirmed in the vendor's own fulfillment policy
• +Single-photo input with no modelling, measuring or scene setup
• +Turnaround is fast enough to iterate live in front of a client

Cons

• −Output is a render with no dimensions, product links or shopping list
• −No API, no batch upload and no team workspace
• −Run by a single developer, so support and roadmap rest on one person
• −A discount code is permanently displayed on the site, which makes the list price hard to take at face value
