CazaDisclosure: Caza makes one of the extensions on this list. We describe every other extension only by what its own store page or website says. We have not tested them.
Short answer: Chrome extensions for Zillow fall into five jobs: deal analysis and cash flow, comps reports, rent estimates, exports, and buyer activity (saves, views, days on market). Pick by the job you do most, then check the price, whether you need an account, and what data leaves your browser.
What do Chrome extensions for Zillow add?
A Zillow listing shows the price, facts, tax history and price history. It doesn’t show cash flow, matched sales comps you can print, a rent check, or a saves-per-day pace and demand score. Extensions fill those gaps on the page you are already looking at, so you don’t retype the listing into a spreadsheet.

How do you choose one?
Start from the job. An investor screening rentals wants cash flow on the search results. An agent answering a client’s link wants comps and a report. A buyer wants to know whether other buyers are leaning in or passing.
Check what the numbers are built from. Rent estimates, tax and insurance drive every cash flow figure. Look for tools that show their inputs and let you change them.
Check the cost and the account. A free tier with a monthly cap is fine for a few listings a week and gets in the way when you browse 30 a day.
Check what leaves your browser. Read the permissions on the store page and the privacy policy. Some tools send the listing to their own servers to analyze it; others work inside the browser.
What no extension can tell you
No extension can see the condition inside a home, what the seller will accept, or what a lender will lend against. Treat any output as a quick screen, then check matched sales and walk the property.
You can try Caza’s core number without installing anything: the free Demand Score calculator turns saves, views and days on market into the same 0 to 100 score. For comps by hand, see how to pull comps on Zillow, and for rentals, cap rate and cash flow on a Zillow listing.
FAQ
What do Chrome extensions for Zillow do?
They add information Zillow doesn’t calculate for you, or turn it into analysis: cash flow and cap rate, nearby sales comps, rent estimates, buyer activity such as saves per day and a demand score, and exports to a spreadsheet or PDF.
Are Zillow Chrome extensions free?
Some are free, some have a free tier with a monthly limit, and some are paid only. The list above shows each one’s pricing as shown on its store page or website in November 2026. Check the listing before you install, because pricing changes.
Are Chrome extensions for Zillow safe to install?
Check three things on the store page: the permissions it asks for, the privacy policy, and whether you need an account. An extension that only reads the listing in your browser shares less than one that sends listing data to its own servers.
Do these extensions work on Redfin or Realtor.com?
Some do. Deal Docket says it also works on Redfin and Realtor.com. Caza works on zillow.com only.
