The Cheapest Virtual Staging APIs in 2026, Ranked by Price per Image

We build Roomagen, one of the APIs ranked below, and it is not the cheapest. This ranking uses only published prices from each provider's own pricing or API page, checked in early October 2026, in US dollars before tax. Where a provider publishes no price, we say so instead of estimating one.

What "Cheapest" Actually Means for a Staging API

Searching for the cheapest virtual staging API turns up numbers that cannot be compared directly: per-render prices drawn from a plan, monthly photo allowances, pay-as-you-go rates, prepaid packs and "contact us" pages. To rank them, we converted each published price into a price per image and noted the smallest amount you must spend to start and whether you can test for free.

Three honesty notes before the table:

• Roomagen is not the cheapest. ModelsLab and InstantDeco publish lower prices per image, and Decor8 matches our lowest pack rate with no upfront purchase.
• Price per image is only half the answer. Unused plan allowance, billing period, overage, output resolution and re-runs all change what you pay per usable image.
• The market moved since our August version. ModelsLab, which we had not ranked, publishes $0.02 per render; Virtual Staging AI lists API access on a public plan; InstantDeco offers monthly as well as annual billing. Deep-Image, which we ranked second at $0.09, is out because we could not verify a current price.

The comparison covers APIs that stage or restyle interior photos from code, the automated equivalent of AI virtual staging or redesigning a furnished room in a web app. The buyers are listing portals and real estate software, but also interior design, furniture retail, rental and hospitality platforms.

The 2026 Price Ranking at a Glance

Providers are ranked by their lowest published price per image.

How to read it:

• Cheapest overall: ModelsLab, which sells access to many AI models, at $0.02 per interior render. Among staging specialists priced in dollars, InstantDeco is cheapest: about $0.05 per photo when its 2,000-photo plan is billed annually and fully used.
• Cheapest with no plan at all: Decor8, at $0.20 per image.
• The middle and the top: Roomagen, Collov and AI HomeDesign on yearly billing sit at $0.20–$0.25; AI HomeDesign on monthly billing and Virtual Staging AI's API plan sit near $0.50.
• Unranked: Pedra, because its dollar cost depends on the exchange rate on the day you pay.

The Cheapest Option for Your Situation

The ranking answers "who publishes the lowest number". This table answers a more useful question: which published price is lowest for the way you will use the API.

Break-even points from the same prices: at $0.20 per image, Decor8 costs less than ModelsLab's $21 Basic plan up to 105 images a month, and less than InstantDeco's 500-photo plan up to 245 images a month on annual billing, or 395 on monthly billing.

Price Per Image vs Price Per Usable Result

The number on a pricing page is the price of a generation. What you budget for is a usable result: an image good enough to publish on a listing, a rental page or a product catalog without someone fixing it first. Three things separate the two numbers.

Re-runs. Generative staging sometimes misses: furniture at the wrong scale, a style that does not suit the room, a sofa across a doorway. If a share r of results needs another run and every run is billed, the cost per accepted image is the price ÷ (1 − r). The rates below are illustrations, not measurements of any provider.

Arithmetic alone rarely reverses the ranking: for a $0.05 image to cost more than a $0.20 one, three of every four runs would have to fail review while the $0.20 provider never missed. What it leaves out is the work: something or someone has to spot bad outputs, trigger re-runs and check them again.

Failure policy. A failed job, meaning an error or timeout rather than a result you dislike, should cost nothing, but policies differ. Roomagen refunds jobs that fail during generation automatically, according to its pricing documentation; re-running a completed result costs another image. Pedra says a thumbs-down on an output with a genuine problem may return the credit automatically. Virtual Staging AI's plans list unlimited renders and Collov's unlimited regeneration, so ask whether that covers API usage. On the other pricing and API pages we checked, we found no per-job failure policy.

Resolution. Prices are not always quoted for the same output. Decor8's $0.20 covers images up to 1,536 pixels on either side, and larger outputs use extra credits. Roomagen's price is for its default 2K render, a 4K render counts as two images, and virtual staging always renders at 2K. InstantDeco's plans include 4K downloads. Compare at the resolution your listings, catalog or portfolio actually need.

The Raw-Model Floor: What the Image Models Cost

Staging APIs run on image-generation models, and some of those models have public per-image prices. Google publishes them for its Gemini image models; Roomagen's image tools run on Google's Gemini image models, so these are the kind of rates we pay ourselves. From Google's Gemini API pricing page:

The $0.039 model our August version cited, Gemini 2.5 Flash Image, is deprecated: Google's pricing page gives its shutdown date as October 2, 2026.

What the floor tells you:

• A $0.20 staging image costs about two to four times a raw 2K model call ($0.101 standard, $0.050 in batch). The spread pays for staging-specific prompting and structure checks meant to keep walls, windows and doors in place (sometimes more than one model call per image), plus retries, job handling, storage and the move to a new model when an old one is retired.
• The floor is not universal. ModelsLab says its interior models are self-hosted, so its $0.02 render is not tied to hosted-model prices like Google's. A low price says nothing about output quality on your photos either way.
• At very high volume, building can win. At 100,000 images a month, a $0.20 API costs $20,000, while the same number of 2K images from Gemini 3.1 Flash Image costs $10,100, or $5,000 in batch, before your own prompts, checks, retries and maintenance. At 2,500 images a month the gap is about $250, which buys little engineering time.

Provider Notes: The Pricing and the Catch

Short notes on each provider, in ranking order. "Catch" is not an accusation: every pricing model has one, including ours.

1. ModelsLab: $0.02 per render

Pricing: each interior render costs $0.02, drawn from the usage a plan includes: Basic ($21 a month) covers about 1,050 renders and Standard ($47) about 2,350. The interior models are self-hosted, so the $149-a-month Open Source Unlimited plan has no per-render charge on them. Source: modelslab.com/interior-api.

Catch: ModelsLab sells access to many AI models, and the interior API is one product among them. Its price is lower than anyone else's here by a wide margin, so a trial should test output quality on your own photos, not cost. The page states no free API trial.

2. InstantDeco: from about $0.05 per photo

Pricing: the API page lists two plans: 500 photos a month for $49 billed annually or $79 monthly, and 2,000 for $99 or $139. Extra photos cost $0.10 or $0.15 on the 500-photo plan and $0.05 or $0.07 on the 2,000-photo plan, depending on billing. One API call equals one photo, and downloads go up to 4K. Source: instantdeco.ai/api.

Catch: $0.0495 per photo assumes annual billing and all 2,000 photos used every month; use 1,000 and the real price is about $0.099. Monthly billing costs 40% more on the 2,000-photo plan and 61% more on the 500-photo plan; the API page says "No commitment. Cancel at any time."

3. Decor8 AI: $0.20 flat, pay-as-you-go

Pricing: $0.20 per image for every API operation, with no monthly fee and no minimum purchase. New accounts get 5 free images, and enterprise volume discounts are available through sales. Sources: Decor8 API pricing and the API reference.

Catch: $0.20 covers outputs up to 1,536 pixels on either side; larger outputs use extra credits. The rate does not fall with volume unless you negotiate, so 10,000 images a month cost $2,000.

4. Roomagen: $0.20–$0.25, prepaid packs

Pricing: 500 images for $125 ($0.25 each), 2,500 for $550 ($0.22) and 10,000 for $2,000 ($0.20); above 50,000, pricing is by arrangement. Packs never expire and stack, and no subscription is needed. Your first API key adds 50 free images, once per account, and renders carry a Roomagen watermark until you buy a pack. One render costs one image at the default 2K, 4K costs two, and failed jobs are refunded automatically. Source: Roomagen API pricing docs.

Scope: every tool the API accepts is documented, 65 as of October 2026, including virtual staging (empty room, restyle or convert a room), virtual renovation, image enhancement, day to dusk, item removal and floor plan to 3D. One image per job and no batch endpoint; results carry no Roomagen branding once you have bought a pack. Jobs are typically ready in 20 to 60 seconds.

Catch: not the cheapest, and our smallest purchase after the free images is $125, while Decor8 has no minimum. The API launched on August 30, 2026, so its track record is short. It adds no disclosure label, results are served from our storage under retention limits (download and keep them), and re-running a result you dislike costs another image.

5. Collov AI: about $0.24, Enterprise plan only

Pricing: API access comes with the Enterprise plan: $127 a month billed yearly ($1,524 a year) for 526 photo credits, with extra photos at $0.24. Monthly billing is also offered; the page lists yearly as 25% off. Source: collov.ai/pricing.

Catch: the entry ticket is $1,524 a year on yearly billing, and photo usage resets each month, so unused credits do not carry over. Below about 500 photos a month, the real price per photo climbs well above $0.24.

6. AI HomeDesign: $0.245 yearly, $0.495 monthly

Pricing: tiers of 200 to 10,000 photos a month. The 200-photo tier costs $588 a year on yearly billing ($0.245 per photo) or $99 a month on monthly billing ($0.495). Plans include API access and credit rollover, outputs carry no AI HomeDesign branding, and signup gives free credits without a card. Source: aihomedesign.com/b2b.

Catch: the advertised "from $0.24/photo" is the yearly-billing price; month to month it is about double. Prices step by tier, so 2,500 photos a month means paying for the 4,000-photo tier unless you arrange a custom plan.

7. Virtual Staging AI: about $0.53, Enterprise plan

Pricing: API access is included in the Enterprise plan: 150 photos a month for $79 a month with yearly billing ($948 a year), about $0.53 per photo. A slider offers more photos; we did not price those tiers. Source: virtualstagingai.app/prices.

Catch: the highest published API price per image in this ranking, and the page labels yearly billing "up to 50% off", so month-to-month billing costs more.

8. Gepetto: price on request

Pricing: a free trial of 50 API calls; the paid API price is not published, and the API page asks you to contact the team to get started. Source: gepettoapp.com/en/api.

Catch: you cannot budget without a conversation. The trial helps you check quality first, but an unpublished price cannot be compared.

Not ranked: Pedra and Deep-Image

Pedra prices in euros: monthly plans from €0.28 to €0.20 per credit (€29 to €120 a month) and annual plans from €0.19 to €0.14 (€239 to €1,008 a year). One credit buys one AI-staged or transformed photo, its plans list API integration, and new accounts get 7 credits without a card. Deep-Image, second in our August version at $0.09, is not ranked because we could not verify a current per-image price on its plans page.

Cheapest APIs for Day-to-Dusk and 3D Renderings

Staging is rarely the only edit a platform needs, and twilight exteriors and 3D views of floor plans are two common companions. At published prices, a 3D render from a sketch or floor plan costs $0.20 at Decor8 and $0.20–$0.25 at Roomagen; ModelsLab's interior API, at $0.02 per render, also lists floor-plan and 3D features.

Two cautions before you choose on price:

• Twilight is not one edit. Decor8 documents a sky replacement, while InstantDeco's description also turns on interior lights. Compare results on your own photos, not feature names.
• A 3D render is a marketing image, not a measured drawing. Roomagen's floor-plan tools warn that the AI redraws text, so check room names and numbers before you publish; the output is an image, not a CAD file.

Our floor plan API comparison and day-to-dusk API guide cover both tasks in more depth.

Total-Cost Scenarios at 500, 2,500 and 10,000 Images

Monthly cost from published prices only, for one month at that volume with one provider. Rows billed yearly assume a 12-month commitment.

What the table says:

1. ModelsLab and InstantDeco are the two cheapest at every volume. At 2,500 images, InstantDeco's annual plan ($124) edges out ModelsLab ($149), because ModelsLab's $47 plan covers only about 2,350 renders.
2. Buying ahead changes the Roomagen row. Packs never expire, so at 500 images a month, the 2,500 pack bought every five months works out to $110 a month. At 2,500 a month, the 10,000 pack every four months works out to $500, level with Decor8.
3. At 10,000 images a month, Decor8 and Roomagen both cost $2,000, Collov about $2,401 and AI HomeDesign $2,450 on yearly billing. Between Decor8 and Roomagen, resolution, failure policy and tool coverage decide, not price.
4. These are prices per generation, not per usable image. Apply the re-run rate you measured in a trial before you sign anything.

When Cheap Is the Right Call — and When It Isn't

Budget-first is a legitimate strategy. It fits some pipelines and quietly costs more in others.

Cheapest-rate is the right call when:

1. Your volume is steady and fills the allowance. A 2,000-photo plan billed annually costs $0.0495 per photo at full use and about $0.099 at half use.
2. You already run QA and retries. If your pipeline catches bad outputs and re-runs them automatically, you can absorb a higher miss rate and keep the price advantage.
3. The output is an intermediate step. Previews, drafts or concept options that a person reviews anyway do not need a failure policy.

Cheapest-rate is the wrong call when:

1. Your volume is seasonal or unpredictable. Monthly allowances and yearly billing charge you for quiet months. Yearly discounts are real (InstantDeco lists 30% off, AI HomeDesign about half the monthly price, Virtual Staging AI up to 50% off), but they only pay if volume holds for twelve months.
2. You need more than staging. Once the roadmap includes day to dusk photo editing, object removal, photo enhancement or 3D views of floor plans, stacking single-purpose providers, each with its own integration, keys and billing, can cost more in engineering time than the per-image saving.
3. Results go straight to customers. When no person stands between the API and a live listing, rental page or catalog, a clear failure policy and consistent output can be worth more than the per-image saving. Listing platforms should also budget for disclosure; our AB 723 guide covers California's rules.
4. You are still pre-launch. Do not commit a year of billing to volume you do not have; the free allowances in the ranking table let you validate quality for $0.

The Bottom Line: Cheapest Rate vs Best Value

If the lowest published price per image is your only criterion, start with ModelsLab at $0.02 per render, then InstantDeco at about $0.05 on its 2,000-photo plan billed annually. If you want no plan and no minimum, Decor8 at $0.20 is the cheapest commitment-free rate. Those are the verified numbers.

If flexibility and protection matter too, the comparison shifts. Roomagen's packs cost $0.25 to $0.20 per image, need no subscription, never expire, refund failed jobs automatically and cover every documented tool from one key, from virtual staging and day to dusk to floor plan to 3D. That costs more per image than InstantDeco or ModelsLab, and it is a reasonable trade only if those terms matter to your pipeline.

To test without spending anything, the Roomagen API quickstart goes from key to first job, and your first key includes 50 free images. If you need an app rather than an API, Roomagen's web-app plans cost $12, $29 or $79 a month ($0.23–$0.40 per image on monthly billing), and our virtual staging software comparison covers other apps.
