Free forever, unlimited plans
Draw as many plans as you want. No plan cap, no watermark, no per-export limit. The editor never asks for a card.
Draw floor plans on your phone or browser. Unlimited plans, no watermark, one-tap Google sign-in. Free forever. Optionally convert to a 3D model when you want to.
What you can do
Everything the free editor does. Sign in with Google in seconds.
Draw
No floor plan file? Measure your rooms and draw the plan yourself. Tap-to-add walls, doors, windows. Room detection labels enclosed spaces.
Trace
Import a photo of a paper plan, an MLS listing image, or a PDF. Overlay as a tracing guide, then draw walls over it for a clean vector version.
Download
Save the plan as PNG or PDF. Print it, email it, drop it into a listing. No watermark, no per-plan cost, no export cap.
3D (optional)
One tap sends the plan to the AI 3D generator. Walk through rooms, share as a link, or export STL for 3D printing (Pro+). Free tier: 3 renders per month.
From blank canvas to a downloadable plan in a few minutes.
Launch it in your browser at app.ritn3d.com/app/dashboard, or on your phone in the Ritn3D app. Sign in with Google or email — no card, no phone number.
Tap point A, tap point B, and a wall is placed. Straight or arc walls. Grid snapping keeps things aligned.
Drop doors and windows onto walls. Room detection labels enclosed spaces automatically as you close loops.
Export the plan as PNG or PDF (free, unlimited). Optionally send it to the AI 3D generator to walk through your space.
No plan cap, no watermark, no export limit.
Draw as many plans as you want. No plan cap, no watermark, no per-export limit. The editor never asks for a card.
Same editor on the Ritn3D iOS + Android app and at app.ritn3d.com/app/dashboard. Draft on-site, refine at your desk.
Import a photo or PDF of an existing plan, use it as a tracing guide, and draw walls over it. Perfect for paper plans.
Not every room is rectangular. Draw arcs, adjust the bulge, and shape non-standard walls without CAD.
Drop doors and windows onto walls. Automatic room detection labels enclosed spaces so you don't have to.
Every change auto-saves as a draft. Resume where you left off on cold-open. Undo/redo any step, any time.

Ritn3D and Sweet Home 3D are the only two on this list with genuinely unlimited free tiers. Sweet Home 3D is a GPL open-source app from 2005 — the desktop version and the browser version are free, the UI is dated, and its official iOS and Android apps are paid. Ritn3D's browser and phone apps are both free.

Yes. Unlimited plans, unlimited PNG and PDF downloads, no watermark on the drawing tool. Sign-in with Google or email is required to save your work and access the editor — no card, no phone number, no email verification. There is no paid tier for the drawing tool itself. Only AI 3D conversion has usage limits (3 free renders per month, then Pro at $9.99/month) because renders count against your account quota.
Yes — sign in with Google or email to open the editor. It takes about 10 seconds, no card, no phone number, no email verification wall. Signing in syncs your plans across phone, tablet, and browser automatically.
Yes. Downloaded PNGs are yours to use — client presentations, listings, personal projects. No attribution required.
PNG and PDF today. STL export is planned for Q4 2026. If you generate a 3D model, GLB and STL downloads unlock at Pro+ tier.
Planner 5D's free tier is unlimited projects but every render is watermarked and low-res, and only about half of the catalog is available on free. RoomSketcher Free is a 10-project archive with watermarked 3D snapshots and pay-per-export floor plans ($38 per level). Ritn3D's editor is genuinely free forever with no caps and no watermark on downloads. The trade-off: we're not a full interior-design tool. We focus on floor plans (walls, doors, windows, rooms) and 3D conversion. If you want furniture placement and paint colors, use Planner 5D. If you want a fast, unlimited free floor plan editor, use Ritn3D.
The mobile app editor works offline once opened. The browser editor needs an internet connection to load, but drawing itself works without a stable connection thereafter.
Yes. Import a photo of a paper plan, a PDF, or an image from an MLS listing. Set it as a tracing guide, then draw walls over it. Adjust as needed.
Your plans are stored in your Ritn3D account on our own infrastructure (Google Cloud). Never sold, never used for training, deleted per your account retention settings.
