How to build an app like Airbnb
The short answer
- An app like Airbnb is a booking marketplace: hosts list places, guests search by location and dates, and your platform takes the payment and pays the host.
- Recommended stack: a Next.js web app first (guests search and book in the browser), Supabase for data and photos, Stripe Connect for payouts, and an Expo app later.
- The hardest part is the availability calendar: two guests must never be able to book the same nights.
What an app like Airbnb does at its core
Hosts create a listing with photos, a description, a price per night and the nights it's available. Guests search for a place and dates, look at listings on a map, and book. The platform charges the guest, holds the money and pays the host after check-in.
Trust holds it together: profiles, reviews from real stays on both sides, messages between guest and host, and clear rules for what happens when someone cancels.
MVP features and what comes later
An MVP (minimum viable product) is the smallest version that real users can use and pay for. It tests the idea before you build everything.
In your first version
- Host listing with photos, price per night and house rules
- Availability calendar per listing
- Search by place, dates and number of guests
- Map and list view of results
- Request to book, accepted by the host
- Payment with one cancellation policy
- Email notifications for booking steps
- Reviews after a completed stay
Later
- Instant booking without host approval
- In-app messaging with attachments
- Several cancellation policies and dynamic pricing
- Calendar sync with other booking sites
- Native apps with push notifications
- Several currencies and languages

Why each layer
- Client, firstNext.js web app
People plan trips on a laptop and find listings through search engines. A web app gets you indexable listing pages and no app store review, so it is the faster first launch.
- Client, laterExpo app
Once guests travel with bookings, a phone app pays off: trip details offline, push messages from the host. It reuses the same Supabase backend.
- CoreSupabase with PostGIS
Listings, bookings, users and reviews are classic related data, which suits Postgres. PostGIS answers "which listings are on this part of the map", and Postgres can block overlapping bookings at the database level.
- PaymentsStripe Connect
Your platform charges the guest, keeps a fee and pays the host later. Stripe Connect is built for this, including onboarding hosts and their payout details.
- MapsGoogle Maps Platform
Address autocomplete for hosts and a results map for guests. Show guests an approximate location until they book, which hosts expect.
- PhotosSupabase Storage
Listing photos are the product. Resize them into a few sizes on upload and serve them through the storage CDN, so result pages stay fast.
The hardest parts of an app like Airbnb, and how to solve them
1. A calendar that never double-books
Two guests clicking "book" for the same nights at the same second is a real case. Postgres can enforce it with an exclusion constraint on date ranges: the database itself rejects a second booking that overlaps the first, whatever the app does.
Store dates as check-in and check-out days in the listing's time zone, not as times in the guest's time zone. Many booking bugs come from that.
2. Search by place and dates
Search combines three filters: inside the visible map area, free for all the requested nights, and enough beds. PostGIS handles the area, and a query against the bookings table removes listings that are taken.
This is fast enough for one city or region. A dedicated search service only becomes worth it when you have many thousands of listings.
3. Holding money and paying hosts
Guests pay at booking, hosts get paid after check-in, and cancellations need refunds that follow your policy. With Stripe Connect, the platform collects the payment and transfers the host's share later.
Write your cancellation rules down before the developer builds them. One clear policy is far easier to build and explain than three.
4. Trust between strangers
Only allow reviews after a completed stay, from both guest and host. A common pattern is to hide both reviews until both are written, so nobody reviews in revenge.
Listings with photos, messages and reviews are user-generated content. Apple's guideline 1.2 requires a way to report content and block users once you ship the app, so build reporting in early.
What you can leave out of the MVP
- Instant booking: let hosts accept each request first
- Dynamic pricing and seasonal rules: one price per night
- Calendar sync with other platforms
- In-app chat: email notifications with a reply link are enough at first
- Native apps until guests ask for them
What it costs
This page gives no price on purpose: the cost depends on your scope and your developer's rate. The App Cost Calculator turns the MVP features above into an hour range, and you add your rate.
This covers the web app. The native app is a later step on the same backend and can be estimated separately with the platform set to Phone.

Frequently asked questions
Should an app like Airbnb start as a website or an app?
As a web app. Guests often plan on a laptop and arrive through search engines, and a web app needs no app store review. Add native apps once people use the product during their trips.
How do I stop double bookings?
Enforce it in the database, not only in the app. Postgres can reject any booking whose dates overlap an existing one, even if two guests book at the same second.
How do hosts get paid?
Through a marketplace payment setup like Stripe Connect. The guest pays your platform, you keep your fee, and the host's share is paid out later, for example after check-in.
What does it cost to build an app like Airbnb?
It depends on how many of the features you include. Put the MVP features from this page into the App Cost Calculator to get an hour range for your version.
