What is the Cost to Develop a Marketplace App Like Craigslist and Letgo?

Online Marketplaces are trending over the internet.

People tend to find products online to buy as they are easy to find and people can browse from their comfortable home place.

Let’s take the example of Craigslist and Letgo, both are online platforms that facilitate the buying and selling of goods and services.

You are here means you are interested in building a such platform.

So, in this article, we will discuss the all essential factors related to these two platforms and eventually find the cost to develop a marketplace app like Craigslist and Letgo.

So, without wasting any time, let’s get started.

Let’s know some basics about these apps.


Craigslist is a classified advertisement website. It covers a wide range of categories, which include jobs, housing, items for sale, services, and community events.

It was founded by Craig Newmark in 1995 and initially served the San Francisco Bay Area.

Over time, it expanded to cover cities across the United States and around the world. It allows users to post free classified ads and browse listings. Users can find contact details of sellers or buyers directly.

On this platform, transactions typically happen in person because Craigslist doesn’t provide payments or shipping options. Due to its simplicity and wide user base, it has been one of the most popular online classifieds platforms for many years.

Now come to the second one!


Letgo was a mobile app and website that focused primarily on the local buying and selling of used goods. It was similar to Craigslist on the basis of its primary functions.

Despite that, it was designed to provide a more modern and user-friendly experience compared to traditional classifieds.

Letgo was founded in 2015 by Alec Oxenford and Jordi Castello and it gained popularity quickly due to its user-friendly interface and features. It allowed users to post listings with photos and descriptions, chat with potential buyers or sellers within the app, and even use a secure payment system for transactions.

It aimed to simplify the buying and selling process. In 2020, Letgo merged with OfferUp, another online marketplace, and the Letgo brand was eventually phased out in favor of OfferUp.

While Craigslist has a long history and is known for its text-based classified ads, Letgo aimed to modernize the local buying and selling experience by focusing on user-friendly mobile apps and multimedia listings.

The landscape of online marketplace platforms continues to evolve. There are various options available to users depending on their preferences and geographic locations.

Moreover, an app with highly custom designs would require more time than mentioned above.

While keeping that in mind the cost calculation would be between $20,000 to $50,000. You can go with as low as $20K or even less in rare cases (depending on requirements) and $50K or more in some cases (if custom requirements are high).
