Best AirDNA Alternatives 2026: What Fills the Gap

You ran an address through AirDNA's Rentalizer, got one clean annual-revenue number, and something about it felt too confident. Trust that instinct. It's the right reason to start comparing the best AirDNA alternatives before you underwrite anything on that figure.

Writing on Awning in April 2026, Dennis Shirshikov found Rentalizer's estimates run 15 to 30 percent off in either direction, worse in thin markets where there aren't enough comparable listings to model from. So a tidy $60,000 projection is really a band from about $45,000 to $78,000 wearing the costume of a single fact. That's the number you buy a house on.

None of that makes AirDNA bad. Its market-level data through MarketMinder is still the deepest money can buy, and I say that as someone who competes with it. I build BNBCalc, so read the bias into everything below, though I've been honest about where each of these six tools beats us.

What to Look For in an AirDNA Alternative

Four questions separate these tools, and each is a spot where AirDNA either wins or leaves a gap. Run every candidate through them and the fit gets obvious fast.

• Property-level accuracy on top of the market read. A market average tells you what the neighborhood does. It doesn't tell you what your specific house nets. Any tool that hands you one confident revenue figure without a comp set or a median behind it is hiding the spread that Shirshikov measured.
• Coverage that matches where you invest. Some of these are US-only. Some pull Airbnb data but skip Vrbo. If you're buying abroad or renting on Vrbo, that gap decides the tool for you before anything else does.
• Whether it underwrites the whole deal. Revenue is half the question. Expenses, mortgage, seasonality, and taxes are the other half, and a market-data tool that stops at the top-line number leaves you to model the rest in a spreadsheet.
• A pricing model that matches how often you use it. AirDNA moved to flat, all-market subscriptions, and its own Capterra reviews sit at 1.3 out of 5, most of the complaints about being auto-charged after canceling. A tool you open twice a year shouldn't bill like one you use daily.

Those four are the axes every tool below gets scored on.

The 6 Best AirDNA Alternatives

Here's the shortlist, scored on the criteria above, before I break each one down.

Tool	Best for	Starting price (as of Aug 2026)	Key limitation
BNBCalc	Underwriting a specific deal and worldwide market research in one place	$30/mo (Calculator) or $79/mo (Markets)	Gross-yield and property-value data are US-only; it won't sell you a house or run your listing
Mashvisor	Comparing Airbnb against a long-term lease on an on-market purchase	About $40/mo billed annually (Lite)	No month-to-month, no free trial, no refunds; thin comps in rural markets
Rabbu	Free, fast address-level screening of US Airbnb deals	Free	Airbnb-only data, US-only, drifts 25 to 40 percent in secondary markets
AllTheRooms	International, multi-country market research	Free tier, then $19/mo per market	Per-market pricing compounds; can't underwrite a property
Chalet	Free US market triage plus a warm agent and lender intro	Free	US-only; the recommended agent also pays Chalet; no deal-level underwriting
RentCast	Cheap long-term rent estimates and a property-data API	Free tier, then $19/mo (Pro)	No short-term or Airbnb data at all

Now the detail, starting with the one I'm biased toward.

1. BNBCalc

BNBCalc is one platform with two products: a Calculator for property-level underwriting and BNBCalc Markets for worldwide research, where markets rank by gross yield and open down to their top ZIP codes. It's the only tool on this list that both finds a market and models the specific deal after every cost.

That's the honest pitch against AirDNA. Where Rentalizer hands you a revenue estimate, BNBCalc runs the whole return: expenses, mortgage payment, depreciation, cash-on-cash, and ROI on the actual address. Markets covers roughly 2,400 markets across 150-plus countries, pulls both Airbnb and Vrbo listings, and Europe is its largest region, so it isn't a US tool with a few foreign cities bolted on.

Where it's weaker: gross-yield and property-value figures are US-only, even though revenue and occupancy run worldwide. And BNBCalc won't sell you a house, run your listing, or match you to an agent. If you want a service arm, Awning or Chalet do that and I don't.

Pricing, as of August 2026: Calculator is $30/month or $199/year, Markets is $79/month or $399/year, both with a 7-day free trial and a 14-day refund window after a charge.

Pick BNBCalc if you want to research a market and underwrite the real deal in one place, whether the property is in Ohio or outside the US.

2. Mashvisor

Mashvisor has been around since 2014, and it's broader than the STR-only tools. It combines Airbnb and long-term rent projections with MLS for-sale search, neighborhood analytics, and ML opportunity scores, so it's built for the buy-or-hold decision more than for tuning a live listing.

Its real edge is putting the Airbnb number and the long-term-lease number on one screen. If you haven't decided which game a property should play, that comparison is the best in the category.

The catch is the commitment. Mashvisor has no month-to-month plan and no free trial, and its pricing-page FAQ states plainly that it doesn't offer refunds, so the smallest realistic spend is about $150 for a quarter of the Lite tier. A Trustpilot reviewer in November 2025 also flagged that data in rural areas "is not readily available," which is the familiar thin-comp problem.

Pricing, as of August 2026 (billed annually): Lite is $39.99/month, Standard is $74.99/month, and Professional is $99.99/month.

Pick Mashvisor if you're shopping on-market and genuinely weighing Airbnb against a long-term tenant.

3. Rabbu

Rabbu pivoted from property management to a nationwide Airbnb-investment marketplace in October 2025, and it now gives away its data. Type an address into Rabbu's free tools, no login, and you get a revenue estimate, ADR, occupancy, and comps for thousands of US cities.

For a fast first-pass filter, that free number is hard to beat, and the business-plan generator produces a lender-facing document that Shirshikov singles out as the thing that sets Rabbu apart.

Then the accuracy question. Writing again on Awning, Shirshikov puts Rabbu within 10 to 15 percent in established tourist markets. In secondary and emerging ones it's 25 to 40 percent off, with a comp set he calls "a black box." The data is Airbnb-only, so it misses Vrbo demand, and it's US-only.

Pricing, as of August 2026: free. Rabbu makes its money on the transaction, through agents and lenders, not a subscription.

Pick Rabbu if you're a US investor screening a lot of deals fast and you'll underwrite the real one somewhere with a full cost model.

4. AllTheRooms

AllTheRooms is the international pick. It tracks occupancy, ADR, RevPAR, and revenue trends with history back to 2016 across 200-plus countries, which is coverage few rivals match outside the US. It was acquired by Deckard Technologies, a GovTech compliance firm, in August 2025.

The free tier gives you a real historical look before you pay, and its patented cross-platform deduplication keeps a market's supply count honest, which matters more than it sounds when you're sizing up competition.

The problem is what it costs to research more than one place. A StaySTRA comparison found an investor analyzing five cities on the Pro tier pays $245/month, because each market is a separate line. It also can't underwrite a property, with no address-level revenue at all, and support has slipped since the acquisition, with its Trustpilot score sliding toward 2.5 out of 5.

Pricing, as of August 2026: a free tier, then Basic at $19/month and Pro at $49/month for a single market each, up to Global at $899/month.

Pick AllTheRooms if you need clean market context across several countries and you underwrite the actual deal elsewhere.

5. Chalet

Chalet is free, US-only, and monetized differently: it pairs market data and calculators with a referral service that matches investors to STR-savvy agents, lenders, and cost-segregation specialists. You don't pay; the partners do, on a closed deal.

The free data suite is genuinely full, with rankings, revenue math, regulation flags, and a for-sale STR board most paid tools skip. And the agent network is STR-specialized rather than a generic Realtor roster, which is a real edge for a first-time out-of-state buyer.

Be clear-eyed about the incentive, though. Chalet's own referral disclosure says these relationships "may influence which partners it presents," so the "best fit" agent is drawn from the pool that pays, and the ranking logic is invisible. It's also US-only, and it isn't built for deal-level underwriting or a portfolio view.

Pricing, as of August 2026: free.

Pick Chalet if you're early-stage in the US, doing market triage, and you want a warm intro to an STR-savvy agent while underwriting the real numbers on your own.

6. RentCast

RentCast is the odd one out here, and I'm including it on purpose. It's an API-first US property-data platform from the same shop as DealCheck, and it estimates long-term, monthly-lease rent plus comps and market reports.

It's cheap and it's wide: a free tier, a $19/month dashboard, coverage of 150 million-plus properties, and a real API that undercuts legacy data vendors. Where comp data is thick, the rent estimates land, and the confidence score is honest about when they don't.

The blind spot is the whole reason to flag it. RentCast has no short-term or Airbnb data at all, no ADR, occupancy, or seasonality. Build an STR pro forma on its number and you've modeled the wrong income entirely. A review on AI and Realtors also notes the web app and API are two separate subscriptions.

Pricing, as of August 2026: a free tier, Pro at $19/month (about $12/month billed annually), and a separate Property Data API from $0 (Developer) up to $199/month (Growth).

Pick RentCast for the long-term rent floor on a house-hack or BRRRR deal, or for US rent data via API. Skip it if short-term revenue is the question you're actually asking.

AirDNA vs the Alternatives: How They Compare

Line them up on the criteria and the trade-offs stop being abstract. Coverage and underwriting are where these tools split hardest.

Tool	Coverage	Underwrites a full deal?	Pricing model
AirDNA	Worldwide market data	No, market read plus a revenue estimate	Subscription, $125 to $150/mo
BNBCalc	~2,400 markets, 150+ countries, Airbnb and Vrbo	Yes, full property-level model after costs	Subscription, $30 to $79/mo
Mashvisor	US, on-market MLS, Airbnb and long-term	Partial, rental math on for-sale listings	Subscription, from about $40/mo annually
Rabbu	US, Airbnb-only	No, free estimate only	Free, transaction-monetized
AllTheRooms	200+ countries, history to 2016	No, market research only	Per-market subscription
Chalet	US only	No, free calculators plus referrals	Free, referral-monetized
RentCast	US, long-term rent only	No, LTR rent and comps	Free, $19/mo, or API

One line of that table is worth reading twice. Only two tools here underwrite the full deal, and everything else hands you a revenue number and leaves the costs to you.

Which AirDNA Alternative Should You Choose?

That underwriting split is really a question about what job you're hiring the tool to do. Here's how I'd match them.

Underwriting one specific property, in the US or abroad? BNBCalc, because the revenue estimate is the easy half and the costs are where deals actually die.

Deciding between Airbnb and a long-term tenant on an on-market purchase? Mashvisor, for the side-by-side on one screen.

Screening a lot of US deals for free? Rabbu for the fastest instant estimate, or Chalet if you also want an intro to an STR-savvy agent.

Researching markets across several countries? AllTheRooms, for the coverage and the history.

Checking a long-term rent floor, or pulling US rent data through an API? RentCast.

And if you need institutional-scale data licensing at contract volume, honestly, stay with AirDNA. BNBCalc doesn't sell institutional data licensing. There's no bulk data feed, no enterprise contract tier, no contact-sales motion. AirDNA does, and that's a real reason to keep it.

Frequently Asked Questions

What Is the Best Free Alternative to AirDNA?

Rabbu and Chalet, both free with no subscription. Rabbu gives you a no-login, address-level revenue estimate for US Airbnb properties and is the fastest first-pass screen. Chalet adds free market rankings, calculators, and an intro to an STR-savvy agent or lender. Both are US-only, and both make money on the transaction rather than the data, so treat their estimates as a starting range and underwrite the real deal somewhere with a full cost model.

Is AirDNA Worth It in 2026?

Yes, if you're comparing several markets you don't already know or underwriting a few deals a quarter. AirDNA's MarketMinder still holds the deepest market-level data in the category, and its numbers are the ones a lender or partner already recognizes. As of August 2026 it runs $125/month for Research or $150/month for Host. Skip it if you run one property you know cold, where the free tier or a spreadsheet does the same job for nothing.

Which AirDNA Alternative Is Most Accurate?

Accuracy tracks a market's data density more than the brand name. For a specific property's full return, BNBCalc models expenses, mortgage, and taxes instead of stopping at one revenue figure. For raw market data, AllTheRooms and Mashvisor are strong where comps are thick. Every tool here, AirDNA included, drifts in thin or rural markets, so discount any single confident estimate and lean on the comp set behind it before you commit.

Which AirDNA Alternative Is Cheapest?

Rabbu and Chalet are free. Among paid tools, RentCast is the cheapest at $19/month, or about $12/month billed annually as of August 2026, though it only covers long-term rent, not Airbnb. AllTheRooms starts at $19/month for a single market, but per-market pricing adds up once you research several cities. BNBCalc's Calculator is $30/month. Mashvisor has the highest entry point because it has no month-to-month option and no refunds.

What Is the Best AirDNA Alternative for International Markets?

For data outside the US, AllTheRooms covers 200-plus countries with history back to 2016, and BNBCalc Markets spans about 2,400 markets across 150-plus countries with both Airbnb and Vrbo listings, Europe its largest region. Rabbu, Chalet, and RentCast are US-only. One caveat on BNBCalc: its gross-yield and property-value figures are US-only, even though its revenue and occupancy data run worldwide, so use it abroad for demand, not valuation.

The Bottom Line

So, back to the number that sent you looking. If AirDNA's market read is fine but its single-address estimate isn't, the honest fix is a tool that underwrites the whole deal, not a second opinion on the same revenue figure.

For most people that's BNBCalc, and you can check the plans on the pricing page. For a free US gut-check it's Rabbu or Chalet, and for international market data it's AllTheRooms. If you want the head-to-head, our BNBCalc vs AirDNA breakdown and the full AirDNA review go deeper on the incumbent.

Whatever you land on, keep sight of what actually costs money. It isn't the tool you pick. It's the one confident estimate you never stress-tested. Treat every projection as the start of the question rather than the end of it, and most of these tools will do the job just fine.
