Compare Hotel Prices Across All Major Booking Sites

Yes, Hotel Ninja is completely free to use with no subscription fees or hidden costs. We earn a small commission when you book through our links, but this never affects the price you pay. The hotel booking sites pay us, not you.

Booking.com, Expedia, Hotels.com, Agoda, Travelocity, and Orbitz.

We’re actively working to add more booking platforms, including direct hotel website comparisons.

Yes, Hotel Ninja works worldwide on all supported booking sites, regardless of which country you’re in or where you’re traveling. Whether you’re booking a hotel in Tokyo, Paris, New York, or anywhere else, Hotel Ninja compares prices across all platforms.

Yes. Hotel Ninja is completely safe. The extension:

• Only accesses hotel booking websites
• Can’t track your browsing on other sites
• Doesn’t collect personal information
• Doesn’t access your passwords or payment details
• Works locally in your browser

We take privacy seriously and only use the minimum permissions necessary to compare hotel prices.

Installing Hotel Ninja takes about 30 seconds:

1. Visit the Chrome Web Store and search for Hotel Ninja or click here
2. Click “Add to Chrome”
3. Confirm the installation
4. That’s it! Hotel Ninja will automatically activate when you visit participating hotel booking sites

Currently, Hotel Ninja is a desktop browser extension only. We’re developing a mobile version and will announce it when available. For now, you can use Hotel Ninja on your laptop or desktop computer.

No account is needed. Simply install the extension and start using it immediately. There’s no registration, no login, and no personal information required.

Chrome automatically updates extensions in the background. You don’t need to do anything. When we release new features or improvements, your extension will update automatically.

When you view a hotel room on any supported booking site, Hotel Ninja automatically:

1. Identifies the specific hotel and room type you’re viewing
2. Searches for that exact hotel and room across all major booking platforms
3. Retrieves real-time pricing including all taxes and fees
4. Displays a comparison showing the lowest price
5. Lets you click through to book at the best rate

This all happens within a few seconds.

Hotel Ninja compares the same room configuration you’re viewing. This is a key difference from other comparison tools. If you’re looking at a room for four, Hotel Ninja shows you prices for rooms that fit your party size across all booking sites, not just the cheapest room available at the property, which may not have enough room for your entire party.

Yes. Hotel Ninja pulls real-time pricing directly from booking sites’ APIs at the moment you search. Prices are current and accurate, including all taxes, fees, and charges. The price you see in Hotel Ninja’s comparison is the actual price you’ll pay at checkout.

Yes. All prices shown in Hotel Ninja’s comparison include:

• Base room rate
• Taxes (state, local, occupancy)
• Service fees
• Booking fees
• Resort fees (where applicable)
• Any other mandatory charges

The price you see is the final price you’ll pay. No surprises at checkout.

Hotel Ninja collects minimal anonymous data to improve the service:

• Which booking sites you use (to prioritize development)
• General usage patterns (to fix bugs and improve features)
• Anonymous error reports (to resolve technical issues)

We do NOT collect:

• Personal information
• Browsing history on hotel booking sites
• Payment information
• Passwords or login credentials
• Your search history or travel plans

No. Hotel Ninja never accesses, sees, or stores any payment information. When you click through to book a hotel, you complete the transaction entirely on that booking site. Hotel Ninja is only involved in the price comparison step, not the payment process.

No. We don’t collect enough data to sell, and we wouldn’t sell it even if we did. Your privacy matters to us. We earn money through affiliate commissions when you book hotels, not by selling data.

Yes. When you click through Hotel Ninja to book on a site like Booking.com or Expedia, you still earn all the loyalty points, rewards, and benefits you would if you booked there directly. Hotel Ninja doesn’t interfere with loyalty programs at all.

Since you book directly with the booking site (not Hotel Ninja), you’ll manage any changes or cancellations through that site’s customer service. Check the cancellation policy before booking, and contact the booking site directly for any modifications.

The key difference is where comparison happens:

Travel comparison sites: You leave the booking site, search on their site, compare results, then return to a booking site to complete your reservation.

Hotel Ninja: Comparison happens automatically right on the booking site you’re already using. No site-switching, no duplicate searches. You see all prices instantly in one place.

Additionally, Hotel Ninja compares the exact room size you’re viewing, not just the cheapest available room at the property.
