Free AI Architectural Rendering in 2026: What You Actually Get
Most “free rendering” offers are trials with a countdown, watermark walls, or free software that needs a €2,000 GPU. Vizbase's free plan is simpler: 5 photorealistic renders a month, refreshed automatically, no credit card, running in your browser. Here is exactly what that includes — and where the limits are.
The full workflow in 60 seconds — upload, auto-detect, set materials, render.
What the free plan includes
A free account gets the same rendering pipeline as paid plans — not a stripped demo mode. That means the complete sketch-to-render workflow:
- Any input: a hand sketch, a SketchUp or 3D viewport export, or a photo of an existing room.
- Automatic scene detection: the AI identifies every element — walls, floor, cabinets, furniture — with clickable masks in 5–10 seconds.
- Per-element materials:click an element and type the material (“light oak, matte”, “Calacatta marble”) or attach a reference photo of the exact finish.
- Photorealistic output in 30–60 seconds, plus smart inpainting to regenerate a single region when one area needs another pass.
Five credits means five full renders a month. That is not production volume — it is honest evaluation volume: enough to run a real client scene through the workflow and judge the output on your own project, not a cherry-picked demo. Browse the gallery to calibrate expectations first.
How the monthly refresh works
Free credits refresh to a monthly floor of 5: at the start of each month, any free account below 5 credits is topped back up to 5. They do not stack — ending a month with 2 credits means starting the next with 5, not 7. There is no expiring trial, no card on file, and nothing to cancel. The plan simply keeps working at low volume forever.
That model exists because the conversion moment for a rendering tool is a real deadline, not a countdown timer. When a deadline arrives and 5 renders are not enough, paid plans start at €29/mo for 30 credits.
Free plan vs free trials vs free software
Against trials: Enscape, Lumion, and D5 Render offer 14–30 day trials, after which the price is €500+ per year per seat. Good software — but the trial clock forces an evaluation sprint. A permanent free tier lets you evaluate on your actual project timeline.
Against free software: Blender with Cycles is genuinely free and genuinely capable — and it needs a serious GPU plus a serious learning investment before the first presentable interior comes out. If you already model in Blender, see our Blender rendering page for how the two combine.

Who the free tier actually fits
Students and recent graduates rendering portfolio scenes. Designers who present a concept a few times a year rather than weekly. Architects evaluating whether AI rendering output is client-ready before proposing it to the firm. And teammates: a free account can join a teamspaceand render from the team's shared pool — only the teamspace owner needs a paid plan.
If you render for clients every week, the free tier will feel small within days — that is what it is calibrated for. Everyone else gets a permanently useful tool for exactly €0.
Frequently asked questions
Is Vizbase actually free, or is it a trial?
It is a real free plan, not a trial. You get 5 render credits with no credit card required, and they refresh every month — the plan never expires. Traditional renderer trials (Lumion, Enscape, V-Ray) end after 14–30 days; a Vizbase free account keeps working indefinitely at 5 renders per month.
Do unused free credits stack up over time?
No. The monthly refresh tops your balance back up to 5 — it is a floor, not a deposit. If you end the month with 2 credits, you start the next month with 5, not 7. Paid-plan credits work differently and accumulate.
What can I render with 5 free credits?
One credit is one render, so five full scenes per month — enough to test the workflow on a real project: upload a sketch or SketchUp view, let the AI detect the elements, set a few materials, and generate. Smart inpainting lets you refine regions without re-rendering the whole scene.
Do I need a GPU or any 3D software?
No. Vizbase runs entirely in the browser — the rendering happens in the cloud. Any laptop that can open a web page can produce photorealistic renders. You do not need SketchUp either: a photo of a room or a hand sketch works as input.
What happens when I run out of free credits?
Nothing breaks — your account and renders stay accessible, and your credits refresh next month. If you need more volume now, Starter is €29/mo for 30 credits, Pro €59/mo for 75, Studio €109/mo for 175, with 15% off on annual billing.
Can a free account join a team?
Yes. Free accounts can join a teamspace created by a paid user and render from the team's shared credit pool — only the teamspace owner needs a plan. When you accept a teammate invite, you both get a one-time 15-credit bonus.
