Craigslist Peek extension – image preview

Craigslist Peek is a Google Chrome and Firefox Extension for Craigslist, kijiji (US), eBay Classifieds, 58 同城 and Facebook Marketplace listings page. Craigslist Peek shows Post and Image Preview.


  1. Google Chrome Extension / Web Store https://chrome.google.com/webstore/detail/craigslist-peek/knpehhedikdgkbmhgagpcpcbclaidlmf (new features and issue-fixes first come here in Chrome and then in Firefox after month or so)
  2. Firefox Addon : https://addons.mozilla.org/en-US/firefox/addon/craigslist-peek
  3. Safari Extension version coming soon. Both Firefox and Google Chrome versions works in Mac, use them for the time being.

I created this from my other Craigslist extension for cars section. And hence Suggestions feature in the cars and motorcycle section.


  • Short description under listing
  • Images under listing
  • Multiple Cities listing. Widens your search area to include neighboring cities.
  • Photo gallery
  • Suggestions in cars & motorcycle section
  • Minimum model Year filter cars & motorcycle section
  • Auto refresh. Shows new posts on top. New post counter.
  • Expands messages in craigslist Discussion forums (beta)
  • Filter craigslist search results (beta)
  • Split listing to Multiple Columns (chrome)
  • Fold / expand listing. Quick toggle fold posts. (chrome only)
  • User can customize looks of it to their taste

I removed some features to keep it simple and practical. Later on I might add some features for particular categories of Craigslist.

Seems new changes in Facebook Marketplace are identical to how I was changing Facebook Marketplace with this extension, so now disabled other stuff and only doing image preview in this.

It looks like some sites (Google News : http://news.google.com and others) have now adopted similar concept to what I been doing in Craigslist Peek and Forum Preview. In these when a person clicks on a Post, it opens in a new-browser-tab. This saves you from clicking Back and re-loading the listing after viewing Post.

Usage Tips:

  • Enable / disable multiple cities or auto-refresh in Settings according to your need.

Fast computer with fast internet connection.

    Also created a related userscript that gives estimated cost of Importing US car or motorcycle to Canada.

    • Gives estimated price from multiple sources. Also provides links for further research.
    • Factory car recalls for the car model.
    • Consumer reviews, this is the real gem.
    • Car reliability information. It shows the msn autos page focused at reliability section. This shows what kinda engine problems occur in that particular car. Other info is also there but reliability info is most useful on that page. Takes like 2 sec to get idea of how reliable that car model is.
    • Scans the posting and shows a highlighted message on top informing about:- accident car, rebuilt car, moving sale, one owner, suggests buyer to ask if the car was involved in an accident.
    • Lists similar (year/make/model) ads from craigslist on top. This gives the idea of going price and the supply/demand.
    • Aggregates car listing.
    • Shows thumbnails from Flickr (Gives idea of what the vehicle looks like and the appeal factor)
    • Recently viewed Ads.

    Cars on craigslist

    Format the car sale ad properly and increase your chances of a quick sale. People use search queries to quickly find the model they are interested in buying. So if you don’t specify the model name in the ad properly then chances are that your ad won’t turn up in search results. Examples: “honda 125”(bad), “honda cbr125r”(good), “beemer”(bad), “bmw”(good). A buyer would be more interested in car sale ads that includes following information:-

    • Title format: The one line title of the car ad should give as much information as possible. The minimum information that it should have is Year, Make, Model and Price. Example: “1992 Honda Prelude SR 150k miles, moving sale $2500 – (Seattle, WA)”
    • Odometer reading: Include odometer reading total ~ km’s or miles.
    • Pictures: Include pictures of the car. Pictures can save lot of time from unnecessary communication. Craigslist listing/search has an option to filter out ads without pictures and lot of buyers do use it. If you have customized car then post pictures showing the customized part. If the car has been in a (minor) accident or fender-bender then post pictures of before and after repair. This might get buyers interested into the car who would otherwise get spooked by mere mention of accident / claims.
    • Car history report: If you know that the car has clean title then spend $50 and obtain a car history report from services like Car Fax reports or Car Proof. Mention in your car ad that the history report is available for the buyer to view. Also giving out VIN# in email to the prospective buyer should be fine.
    • Contact information: Preferably provide both email and phone number in the ad or atleast email. If using craigslist site then use there anonymized email.
