The Best AirDNA Alternative for STR Investors in 2026 (Including the Free One)

You need STR market data. Which tool actually helps you decide whether a market works?

That is the question I hear from investors who have already made up their minds about short-term rentals and are now trying to figure out which platform to trust with their analysis. They are not browsing. They are deciding. And they need a straight answer.

I have been reading market data for nearly four decades, first for a federal agency in Santa Fe and now for STR investors through StaySTRA. In that time, I have learned to spot the difference between a tool that shows you data and a tool that helps you make a decision. Those are not the same thing.

Here is the honest comparison you came for.

What Investors Actually Need From an STR Analytics Tool

Stay with me here, because this distinction matters more than most people realize.

A tool that tells you a market averages $185 per night in August is useful. A tool that tells you whether a specific four-bedroom property at today’s purchase price, with a 7.5 percent interest rate and 25 percent down, will cover its mortgage and clear a DSCR loan threshold is in a different category entirely.

Think of it like a car’s sticker price versus total cost of ownership. Plenty of STR analytics tools show you the sticker price of expected revenue. Far fewer show you whether the math actually works for a buyer at current acquisition costs and interest rates. That gap is where most investors make expensive mistakes.

Investors need at minimum: market-level occupancy rates and ADR benchmarks, comparable property performance data, and the financial modeling to translate revenue into underwriting metrics. DSCR. Cap rate. Cash-on-cash return. Net operating income. If a tool does not speak in those terms, it is a host tool wearing investor clothes.

With that frame in mind, here is how each major platform stacks up.

AirDNA

AirDNA is the name everyone in this industry knows. It has a database of more than 10 million properties worldwide, years of historical data, and market coverage that spans from small U.S. towns to international resort destinations. If brand recognition and breadth are what you are after, AirDNA is at the top of the list.

What it does well: AirDNA’s MarketMinder gives you solid demand-side data: occupancy trends, ADR benchmarks, seasonal patterns, supply growth. Its historical data is genuinely useful for identifying whether a market has been consistent or whether last year’s numbers were an anomaly. For hosts benchmarking their existing property against the local competition, it is a credible tool.

What it misses for investors: AirDNA is priced as a market research platform, not an investment underwriting tool. The starting price is around $20 per month for neighborhood-level data, and meaningful market access runs higher from there, with full-market plans reaching into the hundreds per month. More importantly, AirDNA does not calculate DSCR, cap rate, or cash-on-cash return. It tells you what other properties earn. It does not tell you whether that revenue supports your specific deal at today’s interest rates and acquisition costs. You have to build that model yourself, in a separate spreadsheet.

AirDNA is strongest as a data source for investors who already have their own financial models and want a credible revenue input. If you are looking for a tool that does the investment analysis for you, AirDNA is the first step, not the last.

BNBCalc

BNBCalc takes a different approach, focusing on property-level revenue projections rather than broad market analysis. Enter an address and BNBCalc estimates what that specific property could earn as a short-term rental.

What it does well: The free tier is genuinely accessible. Two free reports and ten property comparables per month gives an investor early in their search a real starting point without any upfront cost. The paid Pro tier at $30 per month is affordable relative to the market. BNBCalc also includes tax deduction estimates, which adds some investor-relevant context beyond raw revenue.

What it misses for investors: BNBCalc is primarily a property calculator, not a market analyzer. If you are trying to figure out whether a market is worth entering before you have identified a specific address, BNBCalc gives you limited help. It does not show market-level supply trends, occupancy trajectory over time, or regulatory risk context. It answers the second question (is this property a good deal?) more than the first question (is this market investable?). For single-property comparisons, it is useful. For market-selection work across multiple geographies, you need a different starting point.

Airbtics

Airbtics is a data platform with global reach that has invested heavily in international markets, particularly across Southeast Asia. For investors evaluating properties in Bali, Phuket, or Tokyo, it offers more depth than most U.S.-focused competitors.

What it does well: Airbtics provides market-level revenue data with seasonality breakdowns, occupancy trend visualizations, and clean data exports. In the markets where its data is strong, the platform is genuinely useful for understanding demand patterns across the year. Pricing starts around $39 per month for individual users.

What it misses for investors: In U.S. markets, particularly smaller and mid-size destinations, Airbtics’ data depth is thinner than AirDNA’s. The platform does not natively calculate DSCR, cap rate, or cash-on-cash return. Like AirDNA, you still need to bring your own financial model to translate the revenue numbers into investment decisions. For a U.S.-focused investor, Airbtics is a solid supplementary tool for specific data needs, but not the primary platform most investors will reach for first.

Rabbu

Rabbu distinguishes itself by building the investment documentation layer on top of market data. Its lender-ready business plans, which translate your property’s revenue projections into a formatted document suitable for a loan application, address a real pain point for investors navigating DSCR loan paperwork.

What it does well: The lender-ready business plan feature is a genuine differentiator. If you are heading into a loan application and need a formatted revenue projection that meets lender documentation standards, Rabbu builds that document for you. It also provides revenue estimators and some market-level data. For investors who find the documentation side of STR financing intimidating, Rabbu reduces real friction.

What it misses for investors: Rabbu’s market data depth is more limited than AirDNA’s or Airbtics’ for broad market research. Pricing runs from $39 per month on the lower end and climbs for more robust access. If you are in the market-selection phase, comparing multiple geographies before narrowing to a property, Rabbu is not the starting point I would recommend. It is better suited as a late-stage tool, once you have identified a market and a property, and need help with the loan package.

StaySTRA (The Free One)

I write for StaySTRA, so I want to be direct about that upfront. I also have nearly 40 years of reading data professionally, and I have no patience for tools that dress thin data in impressive packaging. Here is what the StaySTRA analyzer actually does, including where it falls short.

The analyzer is free to use. One property analysis per month at no cost, with the core investment metrics included. At $7 per month for unlimited analyses and PDF export, the Pro tier is priced for the individual investor, not an enterprise subscription.

What it does well: The StaySTRA analyzer covers more than 2,600 U.S. markets and calculates more than 20 investment metrics from a single property address. Those metrics include DSCR, NOI, cap rate, cash-on-cash return, gross rental yield, monthly cash flow, break-even occupancy, and depreciation tax savings. These are the numbers a DSCR lender or investment underwriter actually uses. The comparable property data is live, not cached from a quarterly snapshot, which matters when you are making time-sensitive acquisition decisions.

Think of it this way: AirDNA shows you the weather. StaySTRA shows you whether your specific vehicle will make the drive in that weather, at your loan terms, at today’s fuel prices.

Don’t let the free tier make you assume the data is thin. The underlying market data covers STR performance across the U.S. with granularity at both the market and property level. The investment metrics are the same ones serious underwriters use. The free tier is free because the goal is to get investors to the right answer, not to gate the useful part behind a paywall.

If you want to run the numbers on a market you’re considering, the free STR analyzer is the fastest way to see whether the deal math works.

Where it falls short: StaySTRA covers U.S. markets only. If you are evaluating properties in Europe, Mexico, Canada, or Asia, it is not your tool. AirDNA or Airbtics offer broader international coverage. StaySTRA also covers fewer total markets than AirDNA’s global footprint, though 2,600-plus markets covers the full range of investable U.S. STR destinations. If you are looking at international opportunities, start with AirDNA or Airbtics for that coverage, then run your U.S. shortlist through the StaySTRA analyzer for the investment analysis.

Comparison at a Glance

Investor Focus reflects whether the tool natively calculates DSCR, cap rate, NOI, and cash-on-cash return without requiring a separate spreadsheet model.

The Honest Verdict

If you are a U.S.-focused investor evaluating markets before making an offer, the StaySTRA analyzer is the most direct path from market curiosity to investment decision. It translates revenue data into the underwriting metrics your lender and your own spreadsheet need. It is free to start. And it covers enough of the U.S. market that most investors will find their target geographies represented.

If you are looking at international markets, AirDNA or Airbtics give you broader coverage. You will need to bring your own financial model to translate their data into investment metrics, but the data itself is solid.

If you are in the late stages of evaluating one specific property and want a quick revenue estimate, BNBCalc’s free tier is worth running.

If you are heading into a loan application and need formatted documentation, Rabbu’s lender-ready business plan feature addresses a real gap.

The real question is where you are in your process. Market selection requires different tools than property-level due diligence. For most investors researching U.S. markets in 2026, the workflow that makes the most sense is: StaySTRA first for investment metrics, AirDNA for supplementary historical context if you want it, and BNBCalc or Rabbu for property-specific documentation at the end of the funnel.

If you are ready to see whether a specific U.S. market works for your investment criteria, start with the free StaySTRA analyzer. It takes a property address and gives you the full investment picture in minutes.

Once you have your market shortlist, our 50-market DSCR analysis breaks down which markets have the revenue-to-acquisition-cost ratios that make DSCR qualification realistic. And when you are ready to move on financing, our STR financing guide covers how DSCR loans actually work and what lenders look for.

We do our best to keep our data accurate and up to date, but markets move fast and we are only human. Always verify current figures directly with local sources before making investment decisions.
