Best Free Floor Plan Software in 2026: 5 Options

The best free floor plan software depends on what “free” needs to accomplish. One person wants a quick AI concept. Another needs careful manual dimensions, offline use, furniture planning, or a 3D presentation.

This comparison covers five products with meaningful free access as of August 11, 2026. Free limits and pricing can change, so check each linked official page before starting a large project or promising a particular export.

Make Floor Plan is our product. It is included here with the same limitations and decision criteria as the other options.

How we evaluated the free options

We reviewed the official free-plan, pricing, and feature pages available on August 11, 2026. Each product was compared using the same six questions: what source it accepts, whether the layout can be corrected manually, whether it supports 2D or 3D output, how many projects the free layer allows, whether free exports have a watermark or resolution limit, and which devices it supports.

This is a workflow-fit comparison based on published product documentation, not a laboratory benchmark. No company paid for inclusion or placement. Make Floor Plan's limits come from our own current product and pricing configuration; the other limits link directly to each vendor's official documentation below.

Quick recommendation by use case

• AI-first concept and image editing: Make Floor Plan
• Browser-based manual planning with 2D and 3D: Floorplanner
• Free open-source and offline workflow: Sweet Home 3D
• Furniture and interior visualization: Planner 5D
• Measured manual layouts and professional upgrade path: RoomSketcher

None of these tools replaces a measured survey, permit set, structural review, or code-compliant construction documentation.

Make Floor Plan: best for an AI-first browser workflow

Make Floor Plan is designed for moving quickly between a written brief, a source image, an edited version, and a 3D concept. The generator offers a no-signup trial, and signup unlocks three trial credits. A manual online editor is also available.

Useful when:

• You want to turn a room brief into an early floor plan concept.
• You already have a floor plan image that needs visual changes.
• You want a browser workflow rather than installing desktop software.
• You want to create a 3D preview after reviewing the 2D layout.

Free limitation: trial generations and free exports are intended for evaluation. HD exports without a watermark, more generations, cloud-saved projects, and commercial use are paid features. See the current Make Floor Plan pricing page for exact limits.

Floorplanner: best for browser-based manual planning

Floorplanner combines manual floor plan drawing, furnishing, and 3D visualization in a browser. Its official pricing page says casual users can keep up to five free projects, with limits of three floors and three designs in total.

Useful when:

• You want to draw walls and place furniture manually.
• You need a browser-based 2D and 3D planning environment.
• You want several free projects kept in one account.

Free limitation: free projects export SD-quality images with a watermark. Higher-resolution exports, 3D tours, and advanced project levels require credits or a subscription.

Sweet Home 3D: best for free offline and open-source use

Sweet Home 3D is a free, open-source interior design application. It can run offline on major desktop platforms and also has an online WebGL version. Users can draw a home plan, arrange furniture, and view the result in 3D.

Useful when:

• You prefer desktop software or need to work offline.
• Open-source software matters to your workflow.
• You want manual 2D planning and a synchronized 3D view.
• You are willing to spend time learning a detailed interface.

Free limitation: the core application is free, but platform editions, asset libraries, rendering expectations, and distribution channels can differ. Confirm that the version you choose supports the operating system and output you need.

Planner 5D: best for furniture and visual exploration

Planner 5D offers a free Basic plan for creating spaces with a limited catalog. Its official help center says Basic users can customize floors and walls, create unlimited draft screenshots, and use up to five custom textures.

Useful when:

• Interior furnishing and visual experimentation are central to the project.
• You want to work across several supported platforms.
• Draft screenshots are enough during early exploration.

Free limitation: the furniture catalog and customization are restricted. Full catalog access, extended customization, AI plan recognition, and plan-dependent renders or textures belong to paid subscriptions or trials.

RoomSketcher: best for measured manual planning and later upgrades

RoomSketcher Free provides the RoomSketcher app for computer and tablet, up to two projects, furniture and material items, room sizes, basic 3D snapshots, and a first AI blueprint conversion according to its official free-plan page.

Useful when:

• You want to enter wall and furniture measurements manually.
• Two trial projects are enough to evaluate the workflow.
• You may later need professional floor plan outputs or business features.

Free limitation: high-quality 2D and 3D floor plans, advanced measurements, Live 3D, branding, and other professional outputs require credits, a project upgrade, or a subscription. The free layer is better understood as a way to draw and evaluate than a source of unlimited professional exports.

How to choose without wasting time

Test the same small project in no more than two tools. Use a one-bedroom apartment or a single renovation option and check these questions:

1. Can you create or import the source you actually have?
2. Can you correct walls, openings, labels, and furniture without fighting the interface?
3. Does the free layer export an image you can genuinely use?
4. Are project, watermark, resolution, or credit limits clear?
5. Can you keep the source and revised versions separate?
6. Does the tool support the device and collaboration style you need?

Choose based on the full workflow, not the prettiest demo image. An AI tool may be fastest for alternatives, an open-source desktop tool may be best for control, and a measured manual planner may be more appropriate when dimensions are central.

If your first task is to describe a layout and see an AI concept, try the free AI floor plan generator. If you already have an image and need to revise it, start with the online floor plan editor.
