Rendair Alternative — Renders Plus CAD Plugins
Rendair markets rendering without plugins. Archome AI takes the opposite position: the plugin is free, and it exists so your viewport never has to become a screenshot.
Last updated: 15 October 2026
What Rendair is
Rendair is a browser AI rendering tool for architects and designers, sold on credit tiers. You bring an image, choose a style, and it returns a rendered version.
It publishes a large templated gallery organised by style and room type, and its interface is available in several languages.
It has landing pages for Revit, SketchUp, Rhino and other CAD packages, and its own copy frames plugin-free operation as a feature — you export an image from your CAD app and work from that.
Where Archome AI differs
Archome AI treats the CAD hand-off as the part worth automating. Free plugins for SketchUp, Rhino and 3ds Max capture the active viewport and post it to the render engine directly; the finished image opens in your browser and lands in your account.
One account covers more than stills: floor plan to 3D, masterplan boards, construction detail sheets, material swap, masked inpainting, 4K upscale, GLB export and short clips.
Structure lock is applied on every image-to-image route, so the render is a restyled version of your building rather than a new building in the same mood.

Price, render time & licence
| Rendair | Archome AI | |
|---|---|---|
| Starting price | See their pricing page — tiered monthly/yearly credit subscriptions | $29/mo (Lite), or free to start |
| Render time | Generated per job in the browser — see their site for a current speed figure | About 30 seconds per image, rendered in the cloud |
| Free trial | 20 free credits at signup, no time limit — not a renewing trial | 100 credits once at signup (3 renders), no card, does not renew |
| Commercial license | Requires a paid plan — the FAQ says free-trial renders aren't for professional use, and lower tiers allow Rendair to feature selected images for promotion | Included on every paid plan |

Where Rendair holds its own
Rendair's credits roll over for as long as the subscription stays active, so a quiet month does not reset a stockpile the way a strict monthly allowance would — useful for a studio whose render load swings from week to week.
Choose Rendair if
- —You want a large ready-made style-and-room gallery to browse before starting
- —You need the interface in Spanish, French, Italian or Portuguese
- —You never open a CAD package and always start from a photo
Choose Archome AI if
- —You model in SketchUp, Rhino or 3ds Max and want the plugin to do the hand-off
- —The project needs plans and details as well as renders
- —You need a downloadable 3D file, not only an image
- —Client iterations have to stay geometrically comparable

The dedicated page covers the free Revit plugin that sends your active viewport straight to the render engine — the hand-off Rendair's own Revit landing page leaves to a manual export-and-upload step.

Frequently asked
What is Rendair?+
A browser-based AI rendering tool for architects and designers, priced on credit tiers, with a large templated gallery organised by style and room type and an interface available in several languages.
Does Rendair have a SketchUp or Revit plugin?+
Its Revit and SketchUp pages are landing pages describing the workflow rather than plugin downloads, and its own copy presents working without plugins as an advantage. Archome AI publishes free SketchUp, Rhino and 3ds Max plugins that send the viewport directly.
Is there a Rendair alternative that also does floor plans?+
Yes. Archome AI runs the same exterior and interior rendering jobs and adds floor plan to 3D view, masterplan sheets, construction details, GLB export and video on the same account and credit pool.
Is Archome AI free to try against Rendair?+
There is a trial, not a free tier. A new account gets 100 credits once, with no card. Every free render costs 30 credits and runs on the Fast engine (Ultra is for paid plans), so the trial is three renders in total and it does not renew — enough to judge output on your own project rather than on marketing samples. Anything you publish — an MLS listing, a portal, a client presentation, marketing — needs a paid plan, which carries the commercial licence.
Can I use the renders commercially?+
On any paid plan, yes — files carry a full commercial licence. Free-plan renders are intended for evaluation and personal use.
What should I actually compare?+
Run the same input through both tools and zoom in on the parts that matter: did the window count change, is the wall line still straight, are the proportions still yours? Marketing pages do not settle this — a side-by-side on your own photo does.
