Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. The largest vendors in interior design software
cannot hold places 1 to 3. Places 1 to 3 go to challengers, vendors outside the best-known brands in a category,
wherever the category has them; the established names follow from place 4 in their ranked order. How it works: placement disclosure ·

The 11 tools, reviewed
#1 RoomSketcher
Floor plans and 3D visuals for homes and listings · Norway · roomsketcher.com
floor plans 3D visuals AI conversion
RoomSketcher is the product to try first because its pricing page is plain and its output is already client-ready. The free plan includes one AI floor plan conversion and two credits, Pro adds the full furniture library, 3D photos, 360 views, branding and print to scale, and Team gives five seats and a dedicated manager.
- Pricing: Per user / month. Free plan with 2 credits; Pro $24 a month and Team $70 a month at list price, each with a 50% annual promotion shown on the page; Enterprise quoted. Free plan: free plan.
- Best for: Solo designers and small studios
- Strengths: 2D and 3D floor plans; AI floor plan conversion; 3D photos by credit.
Where it falls short
Most visual output is metered in credits, so a studio that sends many 3D photos will keep topping up. The furniture and material libraries are generic compared with brand catalogs, and the 3D look is clean rather than photorealistic.
Wrong for
A builder or architect who needs construction drawings with framing and sections.

#2 Planner 5D
Room planner with AI design studio and renders · Lithuania · planner5d.com
room planner AI studio renders
Planner 5D is the quickest way from an empty room to a furnished one that a client can look at. The free plan allows unlimited projects and uses half of the catalog, Premium unlocks the full 10,000-plus items, floor plan upload and standard renders, and Professional adds unlimited 4K renders, 360 walkthroughs and uploads of your own OBJ, FBX or Blender models.
- Pricing: Per user / month. Free at €0 with half the catalog; Premium listed at €59.99 a year; Professional €399.99 a year or €49.99 a month with 4K renders and walkthroughs. Free plan: free plan.
- Best for: Homeowners and freelance designers
- Strengths: 2D and 3D room planning; Floor plan upload to 3D; 10K+ furniture catalog.
Where it falls short
Precision is limited: it is a planner, not CAD, and construction drawings with schedules are outside its reach. The AI tools run on credits, so heavy use means buying more.
Wrong for
A contractor or architect who needs dimensioned drawings, elevations and materials lists.

#3 Floorplanner
Browser floor planner with credit-based exports · Netherlands · floorplanner.com
browser planner credits floor plans
Floorplanner is the least demanding product here when you only need a plan a few times a year. A free account holds up to five projects, limited to three floors and three designs with watermarked 960 by 540 images. A project is then upgraded with credits, from $8.15 for five, for HD or 4K exports, more floors and 3D tours. Subscriptions exist for people who work with it weekly.
- Pricing: Credit-based. Free for up to 5 projects with watermarked SD exports; credits sold from $8.15 for five; Plus and Pro subscriptions bundle credits monthly. Free plan: free plan.
- Best for: Occasional planners and agents
- Strengths: 2D floor plans; 3D views; Multiple floors and designs.
Where it falls short
The pay-per-project model punishes a studio that polishes many projects, and the free exports are low resolution with a watermark. The furniture and styling tools feel older than newer rivals, and the design side is not the focus, so renders are plain.
Wrong for
A designer who produces ten client presentations a week and wants predictable monthly cost. Planner 5D Professional or RoomSketcher Pro give a flat subscription for that rhythm.

#4 Cedreo
Home design software for builders and remodelers · France · cedreo.com
remodeling renders documents
Cedreo sits between a room planner and full architectural CAD, and that gap is useful for remodelers who sell homeowners an addition or a kitchen. It draws floor plans, site plans, cross sections and elevations, then produces 3D renders and presentation documents from the same model.
- Pricing: Per project / plan. Free plan with one project; paid Personal plan per project with 20 rendering credits each; Pro and Enterprise plans for teams, with prices on the vendor's pricing page. Free plan: free plan.
- Best for: Remodelers and small builders
- Strengths: Floor plans; Site plans; 3D visualization.
Where it falls short
Plan switching is one way: its own FAQ says you cannot downgrade from Pro to Personal or from Personal to Free. Monthly rendering credits expire unused.
Wrong for
A decorator who only styles rooms and has no walls to draw.

#5 Live Home 3D
Native home design app for Mac, Windows and mobile · Ukraine · livehome3d.com
perpetual license desktop app 3D rendering
Live Home 3D is a native application, not a browser tab, and that shows in the details: a materials editor, light editor, terrain tools and ray-traced rendering with Radeon ProRender or Cycles on the Pro tier. The free edition caps projects at two stories and adds watermarks to renders, Standard unlocks more, and Pro lifts limits on resolution and exports to formats such as OBJ, USDZ, glTF and FBX.
- Pricing: Perpetual license. Free edition, plus Standard and Pro. Free plan: free plan.
- Best for: Designers who dislike subscriptions
- Strengths: Floor plans and 3D; Terrain and roof tools; 2,400 3D objects.
Where it falls short
The interface is less guided than browser planners, so beginners take longer to get a nice-looking room. AI rendering needs a free account plus purchased credits.
Wrong for
A team that needs shared cloud projects, comments and several simultaneous editors.

#6 Coohom
Cloud interior design with renders and team tools · China · coohom.com
cloud platform renders team design
Coohom is built for a design business with several people and a product catalog to show off. The free Basic plan limits you to three projects with low-detail models and watermarked 1K renders, Pro lifts those limits and adds unlimited projects and uploads, and Elite adds team co-editing, a shared model library and construction drawing downloads at a per-seat price.
- Pricing: Per seat / month. Basic free with 3 projects and watermarked 1K renders; Pro €25 a month billed yearly (€29 monthly); Elite €50 per seat a month billed yearly (€60 monthly); Enterprise quoted. Free plan: free plan.
- Best for: Studios and furniture brands
- Strengths: 3D home design; Floor planner; Photorealistic renders.
Where it falls short
High-quality renders are capped per year on lower tiers, and the free plan's three projects run out quickly. Team features sit on the more expensive Elite tier.
Wrong for
A single homeowner doing one room, who is better served by Planner 5D's free tier or Sweet Home 3D, and a firm that must keep every project with a European-headquartered vendor.

#7 SketchUp
General 3D modeler used for built-ins and interiors · United States · sketchup.trimble.com
3D modeling extensions LayOut
SketchUp is the tool for a space that no catalog covers: a curved reception desk, a staircase, a fitted wardrobe with odd dimensions. You model the geometry yourself, borrow furniture from 3D Warehouse and use LayOut to turn views into scaled sheets. A large extension ecosystem adds rendering, which is how interior designers get photorealism.
- Pricing: Per user / month. Per user subscriptions billed annually: Go $10.75, Pro $33.25 and Studio $71.58 a month as listed on our CAD ranking; a 7-day Pro trial needs no card. Free plan: free trial.
- Best for: Designers of custom millwork
- Strengths: Desktop, web and iPad modelers; 3D Warehouse library; LayOut 2D documents.
Where it falls short
There is no built-in furniture planner or one-click room: every wall and object is drawn by hand. Rendering depends on extensions that cost extra or on another renderer. Pricing is per user and the Studio tier is Windows only.
Wrong for
A homeowner or a stager who just wants to rearrange furniture in an afternoon.

#8 Chief Architect
Residential CAD with interior, kitchen and bath tools · United States · chiefarchitect.com
residential CAD kitchen and bath construction drawings
Chief Architect is aimed at designers whose output is a drawing package. Walls, ceilings and floors form as you draw, cabinets snap to walls and a materials list updates with the model. For interior and kitchen and bath work the company points to floor and space planning, manufacturer catalogs and custom colors and materials, plus a Style Palette to restyle a room for client options.
- Pricing: Per user / year. Premier is $1,995 a year or $229 a month, per the vendor's home page; a free trial can be downloaded. Free plan: free trial.
- Best for: Kitchen and bath designers
- Strengths: Automatic roofs, framing and dimensions; Floor and space planning; Manufacturer and custom catalogs.
Where it falls short
It is expensive for a designer who only makes moodboards, and the learning curve is real. The software runs on your computer rather than in a browser, so collaboration happens through exported files and the viewer.
Wrong for
A decorator or stylist who needs quick visuals for a living room.

#9 Homestyler
Cloud 3D design with a large model library · China · homestyler.com
cloud planner AI tools model library
Homestyler is the cheapest route to a lot of content. The Basic plan is free with a cloud 3D floor planner, unlimited 1K renders and over 100,000 free models and materials, while Pro and Master add 2K and 4K renders, uploads of your own textures and models, and designer-directory features. AI tools include image to image, image to moodboard and an interior design agent.
- Pricing: Per user / month. Basic free with unlimited 1K renders; Pro from €4.52 a month, Master from €9.13 a month, Team from €18.09 per seat a month; Enterprise quoted. Free plan: free plan.
- Best for: Hobbyists and freelance designers
- Strengths: Cloud 3D floor planner; 100K+ free models; Custom furniture.
Where it falls short
We could not read a legal address on the site, and the operating entity comes from an app-store listing, so this is the weakest provenance in the list. Free 4K renders are paid per use, and a lot of the model library is aimed at the Asian market.
Wrong for
A European firm that has to document where its vendor is based and who owns the product.

#10 Sweet Home 3D
Free open-source interior design application · Italy · sweethome3d.com
open source desktop free
Sweet Home 3D draws walls, drops in furniture from a catalog, and lets you walk through the result in a 3D view. It is distributed under the GNU General Public License, runs in 29 languages, and can take extra textures, models and plug-ins from its community. Version 7.5 is dated May 2025, and the legal notice names Space Mushrooms srl of Milan as publisher.
- Pricing: Open source. Free to download under the GNU General Public License; donations are optional. Free plan: open source.
- Best for: Budget-conscious home planners
- Strengths: 2D plan drawing; 3D virtual visit; Walls with curves and slopes.
Where it falls short
The interface looks and feels like older desktop software, photo-realistic output is slow and basic, and there is no cloud collaboration or AI. The default furniture catalog is modest. A designer presenting to paying clients will find the look dated beside Planner 5D or Coohom.
Wrong for
A studio that wants slick client presentations or shared team projects.

#11 Houzz Pro
Business software with design tools for pros · United States · pro.houzz.com
business suite 3D floor plans CRM
Houzz Pro is not a design program first. Its 3D floor planner and mood boards sit beside a CRM, estimates, proposals, invoicing and a client dashboard, so a designer who bills for time and materials can run the whole job in one place. The free Basic plan gives a taste, and the Pro plan, $249 a month on an annual contract with one seat, adds the paid tools.
- Pricing: Tiered / month. Free Basic plan with a few tools; Pro $249 a month after a 30-day trial as an annual plan with one seat; Custom plan quoted. Free plan: free plan.
- Best for: Design-build firms with client flow
- Strengths: 3D floor planner; Mood boards; Estimates and proposals.
Where it falls short
The planner is lighter than dedicated tools, rendering is limited, and the price is high for a solo designer who does not need the business modules. Extra users cost more, and the product pushes you toward paid advertising.
Wrong for
A designer who only wants to lay out rooms and make renders.

Questions and answers
What is the best interior design software in 2026?
RoomSketcher ranks first of 11, best for solo designers and small studios. Planner 5D is second (homeowners and freelance designers) and Floorplanner third (occasional planners and agents). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Is there free interior design software that is good enough for clients?
Sweet Home 3D is free and open source, and RoomSketcher, Planner 5D, Floorplanner, Coohom and Homestyler have free tiers. Good enough depends on the output: free tiers usually limit render size, add watermarks or cap projects.
What is the difference between a room planner and interior design CAD?
A room planner places furniture on a scaled plan and shows a 3D view, which is enough to test a layout. CAD adds wall assemblies, elevations, schedules, dimensions that update with the model and drawings a builder can price.
Can I use these tools for commercial client work?
Usually yes on paid tiers, and often no on free ones. Read each vendor's terms for commercial use, watermark removal and image ownership.
Do I need a powerful computer?
Browser tools such as Planner 5D, Coohom and Homestyler render in the cloud, so a mid-range laptop works. Cedreo asks for a recent computer with 16 GB of memory and a mouse.
How much does interior design software cost?
The range is wide.
Which tool is best for AI renders and restyling a photo?
Planner 5D AI Studio restyles a room photo while keeping the layout, Homestyler offers image-to-image and an interior design agent, RoomSketcher sells AI renders by credit, and Live Home 3D has a credit-based cloud AI render.
Can I turn a hand sketch or an old plan into a digital floor plan?
Yes. RoomSketcher and Planner 5D both advertise AI conversion of an uploaded floor plan into an editable project, and RoomSketcher can also draw your plan for you from a sketch or blueprint, delivered the next business day.
Is SketchUp good for interior design?
It is good for custom millwork, built-ins and unusual spaces because you can model anything, and its 3D Warehouse supplies furniture.
Where does my project data live?
Browser products hold projects on the vendor's servers, which are in different countries from the vendor's head office, so read the privacy policy. Sweet Home 3D and the desktop license of Live Home 3D keep files locally.
Should a designer pick a business suite like Houzz Pro instead?
Only if proposals, invoicing and lead generation matter as much as the visuals. Houzz Pro bundles a floor planner, mood boards, estimates and a client dashboard, but its design tools are lighter than a dedicated planner.
