Sweet Home 3D vs Planner 5D: Which Free Floor Planner Should You Use

One of these is software you install once and own forever. The other is a website you log into and pay a subscription for. That single fact — not furniture count, not render style — is the real reason Sweet Home 3D and Planner 5D feel so different to actually use, and it's the thing most side-by-side feature tables skip past entirely. Everything below traces back to that one structural split: what each free plan really lets you do, how the renders hold up, how much friction shows up while you're learning either one, and who each tool actually suits. By the end, if you'd rather skip the install-versus-subscribe tradeoff altogether, there's a free floor planner that handles it differently from both.

The Core Difference: Open-Source Desktop vs. Subscription Web App

Sweet Home 3D is free, open-source software you download and run on your own computer — Windows, macOS, or Linux. There's no account to create and nothing running on a remote server, so there's also nothing for a company to meter. Once it's installed, every feature in the program is available to you for as long as you use it. The tradeoff is that rendering speed and quality depend entirely on your own computer's processing power, and you're working locally rather than in a synced cloud project.

Planner 5D is the opposite model: a browser- and app-based tool running on Planner 5D's servers, with a free Basic tier sitting underneath three paid tiers (Premium, PRO, Enterprise). Because it's a subscription product, the free tier is built to be just functional enough to get you interested, then gate the things that make a project actually usable — furniture catalog size, render resolution, customization — behind a recurring payment.

That's the difference this whole comparison keeps coming back to: Sweet Home 3D's "free" means complete and unlimited, but tied to your own hardware. Planner 5D's "free" means accessible from any device, but deliberately incomplete until you pay.

What Each Free Tier Actually Lets You Do

Sweet Home 3D (entirely free, no tiers to upgrade):

1. Full 2D plan drawing with precise measurements, polylines for non-rectangular walls, and fully customizable dimensions
2. Simultaneous 2D and 3D view, so the model updates in real time as you edit the plan
3. Import an existing blueprint image to trace over, or import a room scan (via a bundled iPhone Tape Measure workflow) to build a plan from real measurements
4. A built-in furniture catalog that's smaller than Planner 5D's, offset by the ability to import your own OBJ models — so the catalog size isn't really a hard ceiling
5. Photo-quality rendering and walkthrough video generation, with no render count limit, no watermark, and no resolution cap — output quality is limited only by your own computer's processing time

Planner 5D Free (Basic):

1. Unlimited projects, but only one in progress at a time
2. Roughly 80 furniture items available, out of a catalog that runs into the thousands on paid tiers
3. No item resizing and no texture or material editing
4. Snapshots (renders) are low-resolution and carry a watermark
5. No panoramic view, no AR view, and no clean, watermark-free export

Put plainly: Sweet Home 3D's free tier isn't really a "tier" at all — it's just the product. Planner 5D's free plan is a sampler by design, built to show you roughly 80 of several thousand furniture pieces and renders that can't leave the app looking presentable, thanks to the watermark and the resolution cap.

Rendering Quality

Sweet Home 3D renders locally on your own CPU. The quality ceiling is genuinely high — the engine can produce photo-realistic stills and walkthrough videos with adjustable lighting and sun position — but getting there takes patience. Complex scenes at high settings can take real time to render on an average computer, since there's no cloud acceleration to speed things up. You're trading zero ongoing cost and a high quality ceiling for your own hardware's time.

Planner 5D renders in the cloud, so results come back quickly regardless of what device you're on — but on the free plan, every render is low-resolution and watermarked, which makes it unusable for anything beyond a private rough preview. The Premium plan unlocks a handful of high-quality renders per month (5 on the Individual Monthly tier); only PRO removes the watermark entirely and adds unlimited 4K output.

Patience buys you quality with Sweet Home 3D; money buys you speed with Planner 5D — and on the free tier of either, you don't get both at once. Want a sharp, watermark-free render in thirty seconds flat? Neither free plan delivers that. The choice isn't really about which tool renders better — it's about which kind of cost you'd rather pay to get there.

Learning Curve

Sweet Home 3D's interface looks dated by 2026 standards but is stable and predictable — once you understand the basic pattern of drawing in 2D while watching 3D update, the tool doesn't fight you. It's consistently described as approachable for beginners specifically because there's no account creation and no upsell prompt interrupting the workflow: there's no feature you discover later that turns out to require payment, because there isn't a payment tier to discover.

Planner 5D's interface is more modern and friendlier for the first five minutes — drag-and-drop, AI-assisted layout suggestions on paid tiers, and a generally polished UI. But the free plan's limitations create a different kind of friction: with only ~80 furniture items and no resizing or texture editing, it's hard to get a representative sense of what the tool can actually do before you've paid for something. The learning curve itself isn't steep — the limitation is evaluating the real product without hitting a paywall first.

Who Should Use Which

Sweet Home 3D fits you if you want a complete tool with no strings attached, you're comfortable installing desktop software, and a dated interface is an acceptable tradeoff for full functionality at zero cost with no feature gates. It's a particularly strong fit if you're planning to import a real blueprint or a scanned room and work from precise measurements, since accuracy is where its design actually shows.

Planner 5D fits you if you want to work from a browser or phone without installing anything, you're doing one quick layout rather than a long-running project, and you're fine with — or planning to pay for — full furniture access and clean renders. It's also the better fit if AI-assisted layout suggestions matter to you, since Sweet Home 3D doesn't offer that at all.

There's no upgrade path between these two mindsets — you don't grow from one into the other, you just pick a side going in. Spend your computer's patience, or spend actual money. That's the whole decision.

A Third Option That Skips the Tradeoff

Maybe neither side of this actually appeals to you — installing desktop software isn't your thing, but neither is paying to unlock furniture past item #80. That combination is exactly the gap a free floor planner can fill: browser-based like Planner 5D, minus the subscription gate on the catalog and the render quality.

Sweet Home 3D and Planner 5D aren't the only two names worth knowing in this space, either. See how they compare to other free floor planners that people on Reddit actually bring up when asked, rather than ones that simply paid for placement on a review site.

Frequently Asked Questions

Is Sweet Home 3D really free with no hidden costs?

Yes. It's open-source, with no account, no subscription, and no in-app purchases. The only real cost is your own computer's processing time for rendering, since everything runs locally instead of through a paid cloud service.

Does Sweet Home 3D work on Mac and Linux, or just Windows?

It runs natively on all three, since it's built on Java. Rendering speed depends on your machine's hardware, not on which operating system you're using.

Will Planner 5D charge me automatically after a free trial?

This shows up often enough in user reviews on sites like Capterra and Software Advice to be worth taking seriously — several users report being charged even after attempting to cancel before a trial ended. The free Basic plan itself doesn't require payment info, but if you start a trial tied to a yearly subscription, cancel well before the trial ends and confirm the cancellation actually went through.

Is the Planner 5D free version good enough to plan a small apartment?

For a rough layout, yes — you can draw walls and place furniture from the roughly 80 free items. For anything you'd want to look at again afterward, the lack of resizing, texture editing, and watermark-free export makes it feel more like a sketch than a finished design,

even for one small room.

What's a good alternative if Sweet Home 3D's interface feels too dated? RoomSketcher and Coohom both run as more modern web- or app-based tools with free tiers, though each comes with its own limits worth checking before committing a real project to either.
