How to Build a Fashion Marketplace App Like Depop: Features, Cost and Business Model

It’s 12:40 a.m.

Imagine a hypothetical 19-year-old in Manchester taking a picture of her old skinny jeans on the floor of a bedroom. One photo, one tap, and the app writes the description for her. By the time a buyer arrives in Chicago for breakfast, he or she has paid.

The loop is the business, and every founder asking about an app like Depop is in fact asking how to build it. 

The short answer: An application similar to Depop is a resale market where listing takes seconds, the feed is social and everything, from payment to shipping to buyer protection, is done within the application. An MVP costs roughly $45,000–$80,000 and takes 4–6 months. The code isn’t the hard part. The tricky thing is to have enough sellers put their properties on the market before buyers are ready to make an offer.

What is Depop?

Depop is a UK-based, mobile-only platform that lets people sell second-hand and vintage fashion, and the resale sector is outpacing fashion. With GlobalData, ThredUp has developed its 2026 Resale Report, which forecasts that the second-hand market will grow to $393 billion by 2030. This is more than twice the growth rate of the total apparel industry, with Gen Z and millennials accounting for over 70% of that increase.

The scale of Depop itself is a case study. Depop was established in 2011. It announced $1 billion in gross merchandise sales through 31 December 2025, with seven million active buyers, nearly 90% under 34, and more than three million active sellers.

In 2021, Etsy acquired Depop for one point six billion dollars, but later Etsy sold Depop. On 30 July 2026, Etsy, acting as a seller, announced that the sale of Depop to eBay was completed for one point four billion dollars, in cash after adjustments.

This is what is important to founders when it comes to the details. According to the same ThredUp report, the issue is not those who want to sell secondhand items; it’s those who want to sell them in the first place. The marketplace that is the simplest to use to list on is the rarest asset in the category.

While studying the websites, Vinted, Poshmark, Mercari, and eBay are among the sites that also battle for sellers when you are searching for the best Depop alternatives before you hit that line of code. The Shein business model is a case study, as it is a retailer of new fast fashion to the same Gen Z consumers who are sitting on the other end of the supply chain.

How Does Depop Make Money?

Depop revenue mainly comes from a commission fee that Depop charges to buyers from payment processing fees and from boosts. In July 2024 Depop eliminated a selling fee on transactions made by US sellers.

Depop announced that it removed the selling fee from US listings and introduced a new buyer marketplace fee of up to 5% plus, up to $1. Sellers in the US are still responsible for a 3.3% + $0.45 processing fee on the transaction total (shipping + taxes).

Table 1: How Depop’s published US fee structure works

Revenue stream	Who pays	How the stream works
Buyer marketplace fee	Buyer	Depop charges US buyers up to 5% of the item price plus up to $1 to fund Depop Protection and support.
Payment processing fee	Seller	Depop Payments, powered by Stripe, charges US sellers 3.3% + $0.45 on the total transaction amount.
Boosted Listings	Seller	Sacra reports sellers pay 8% only when a buyer who saw a promoted listing buys within 28 days.
Selling fee	Nobody in the US	Depop removed the 10% selling fee for newly listed US items on 15 July 2024 to attract more sellers.

It’s what it would look like at a small scale, based on Depop’s published US fees. Make 10,000 orders each month, with an average item sold at $35, or a gross merchandise value of $350,000.

The buyer fee at 5% + $1 earns $2.75 per order, or $27,500. This increases at 8% by 10% of orders, which is $2,800. Before refunds, support and fraud losses, and cloud costs, platform revenue is roughly $30,300, or 8.7% of gross merchandise value.

When it comes to buyer-side fees, there is a risk involved. However, if the protection for the buyer is not worth the checkout fee, then price-sensitive Gen Z shoppers may end up on fee-free platforms like Vinted, Sacra says.

How do Resale Apps Handle Payments, Shipping And Trust?

Resale apps manage payments, shipping, and trust, which keeps the money in the app until it’s delivered and offers buyer protection depending on the in-app payment method.

Depop processes payments via Depop Payments, which is powered by Stripe, and states that payments on Depop Payments are covered by Depop Protection (terms and conditions apply).

That won’t cover money sent via another payment application, which is why switching a buyer from one app to another is the standard resale scam. Shipping is the same: purchase labels in-app from a shipping API like Shippo or EasyPost, ensuring that every order has some proof of shipping.

• Verification: Scan everyone’s email and phone, as well as perform ID and payout verification with the payment provider for sellers.
• Fraud controls: Disable bank details and payment-app handles in chat, and report new accounts offering large offers.
• Disputes: Allow buyers to open a case within a time period after delivery. Let sellers respond with tracking details and photos. Admin will make the decision.
• Counterfeits: Add a report button on every listing. Flag luxury brands, for image review.
• Tax Reporting: Gather seller tax information. In October of 2025, the IRS announced that it will only issue Form 1099-K if the platform has over 200 transactions and more than $20,000 in gross receipts, and if the platform is located in the EU, it will be subject to the DAC7 reporting requirements. Verify commitment with advice.

Once payments, shipping, fraud prevention, and compliance are in place, the next step is to identify the essential components that make a fashion resale marketplace user-friendly for both buyers and sellers.

What Features Does a Fashion Resale Marketplace Need?

The main characteristics of a fashion resale marketplace consist of one photo listings, a feed and a search functionality that has fashion filters. In-app chat and offers are another feature that should be provided on the platform. In-app payments, shipping labels and tracking are required.

Ratings and reviews help users make decisions. An admin console with moderation is also essential, for a fashion resale marketplace.

While Apptunix’s marketplace software development guide details the 15 features that every multi-vendor marketplace requires, the table below expands on what makes a resale app.

List speed is the product, every listing is inventory, and resale is what is missing. Apptunix suggests that you aim for one listing to be displayed in less than 60 seconds.

Table 2: Core features of a Depop-style app and when to build them

Feature	What the feature does	Release stage
One-photo listing	Lets a seller photograph an item, then edit a draft with category, size and price already filled in.	MVP
Social feed	Shows new items from followed sellers, with likes and follows that turn buyers into followers.	MVP
Search and filters	Lets buyers narrow listings by size, brand, condition, price and style tags.	MVP
Chat and offers	Lets buyers negotiate through in-app chat without leaving the platform and keeps conversations on record for disputes.	MVP
In-app payments	Processes payments within the app and allocates funds among the seller, platform and payment processor. Funds can be held until the transaction is completed through a compliant payment provider.	MVP
Shipping labels	Lets sellers buy shipping labels in-app and attach a tracking ID to every order.	MVP
Ratings and reviews	Builds seller reputation and gives buyers reassurance before making a purchase.	MVP
Admin console	Handles moderation, refunds, reports, payouts and fee settings.	MVP

Social is not for show. Depop’s followers and likes are at the heart of the product, as 46% of ThredUp’s reporters said they discover products via social feeds, creators, and in-person browsing.

Which AI Features Should an App Like Depop Have?

The four AI capabilities a modern resale app should have are: listing from a single image, price recommendations, visual search, and a personalized feed. The generation of descriptions from a single photo was introduced by Depop on 12 September 2024, powered by generative artificial intelligence and image recognition, which completes the description, as well as the category, colour, sub-category, and brand.

The blank text box is the most valuable AI capability a resale app can ship first, as it is the most important step for most resale sellers to give up on. Business Insider reported that Depop’s Chief Product and Technology Officer, Rafe Colburn, had said that the feature had resulted in a “real uplift in listings created, listing time, and completeness of listings.”

• Auto-listing: A vision-language model returns the category, brand, colour, and a draft description from one photo, which is called auto-listing.
• Pricing suggestions: A model that compares similar items sold and recommends a pricing range; Depop’s pricing recommendations are similar and use more nuanced language and vision models.
• Visual search: With the search image embeddings being stored in a vector index, enable searching through images and also similar items finding.
• Personalized Feed: The personalized feed takes into account user’s following, liking, sizing, and brand preferences in order to rank the content seen by each shopper.

AI influences trust, as well. 48% of shoppers use AI shopping tools when shopping secondhand, ThredUp revealed, while eBay stated it would implement trust mechanisms like authentication on Depop. 

Here’s one truthful caveat: AI listings don’t always assign the correct brand, so sellers manually correct each part and keep notes of corrections to fine-tune the system. 

What Tech Stack Powers a Depop-style App?

The Depop app is built on a cross-platform mobile client, an API backend, a search index, a payments layer, and an image pipeline. While it is not public in detail, Apptunix recommends the following for a new build using the architecture of Depop.

The stack should be built to move fast for the MVP so we can get it to market quickly. We also need to keep things stable as the number of listings grows and more users come on board. We add AI features.

All the options listed are widely used, well-supported, and easy to find talent for. That’s really important when you’re scaling a marketplace and every day counts.

Table 3: Typical tech stack for a fashion resale marketplace

Layer	Typical choice	Why it fits
Mobile app	React Native or Flutter	One codebase works for both iOS and Android, helping keep the MVP budget low.
Backend	Node.js or Python	Both support API operations, chat features and background jobs, with libraries for payment integrations.
Database	PostgreSQL, with Redis for caching	PostgreSQL manages orders, payouts and disputes, while Redis can improve feed performance through caching.
Search	Elasticsearch, OpenSearch or Algolia	Fashion filters require faceted search across attributes such as size, brand and price.
Payments	Stripe Connect	Supports marketplace payment flows and seller payouts. Depop uses Stripe for payment processing in the US.
Images and AI	Object storage, a CDN and a vector index	Photos are central to the shopping experience, while embeddings can power visual search and similar-item recommendations.

Founders often miss the importance of the image pipeline. The image pipeline starts by compressing photos on the device. After that the image pipeline stores the files in object storage. 

Then the image pipeline serves resized copies through a CDN and the image pipeline can also moderate images and run AI models asynchronously so the photo list does not have to wait.

Even if someone is using a phone connection in the middle of the night, a seller should see a listing appear quickly. As the catalog becomes larger and larger, the same system will make it easy to predict the cost of using the cloud.

What Should an MVP include, and What Can Wait?

The main features of a Depop lookalike app include one photo listings, basic feed, search, in-app messaging, in-app payments, shipping labels, and the administration panel. Features like support for AI pricing, visual search, boosts, and handling regions can be added later.

Apptunix’s marketplace app development methodology focuses on the MVP – list, discover, pay, ship, review. Everything that doesn’t shorten the loop or secure the money is for version 1.

Table 4 illustrates the split, line-by-line, allowing you to see which features will be included in the first release, and which ones will be relegated to a later one.

Table 4: MVP scope versus full build

Area	In the MVP	Built later
Listing	One photo with a manually written description.	AI-powered auto-listing and price suggestions.
Discovery	A feed of new items, plus search with size, brand and price filters.	Visual search and personalized ranking.
Payments and shipping	One-country support with in-app card payments and shipping labels.	Wallets, multi-currency support and international carriers.
Trust	Reporting, basic dispute handling and ID checks at payout.	Authentication services and fraud scoring.

Supply comes first. Since the name of ThredUp provides the primary constraint for resale, Apptunix suggests recruiting 200–300 sellers and bringing 1,000 live sales listings prior to making the app open to buyers.

Is There a Market for A Regional Depop in The Middle East?

Yes, but it is a small and young market, and a regional Depop has to go for a small niche.

Future Market Insights predicts the GCC secondhand apparel market will grow from $1.3 billion in 2025 to $4 billion by 2035. IMARC estimates the GCC secondhand luxury goods market will reach $617.3 million in 2024.

Bazaara, a UAE-based peer-to-peer fashion resale platform has raised $230,000 in seed funding. Its Arabic interface and support for right-to-left design and local payment methods were challenges the company had to address.

How to Develop an App Like Depop?

There are seven steps in the development process of an application such as Depop. These include:

• Discovery: Define target niche, payment model, marketing approach and strategy towards attracting sellers as well as MVP scope definition.
• UX and prototype: Design the listing, feed and checkout flows then test with buyers and sellers. 
• Core build: Build accounts, one-photo listing, the feed, and search.
• Payments, shipping and chat: onboard the payment provider, add label purchase and in-app chat.
• Add the following Trust and admin tools: Disputes, Reporting, Moderation, and payouts.
• Testing: Firstly, it is needed to perform testing related to payments, security issues and performance, then conduct a beta testing with about 200-300 seed sellers to check the quality.
• Open for viewing: First, start with 1,000 listings, then post new ones every week, and slowly introduce AI features.

How Much does It Cost to Build an App Like Depop, and How Long Does It Take?

Depop’s estimated cost to build an MVP ranges from $45,000 to $80,000. A full first version is expected to cost between $90,000 and $160,000. A multi-region platform could cost $180,000 to $350,000 or more according to Apptunix estimates.

Apptunix’ guide to general marketplace answers a simple MVP at 3-6 months, and a full marketplace at 9-18 months, after which, of course, the resale app falls.

The three factors that most affect the number moving are: countries launched, number of AI solutions launched, and the depth of the trust and dispute tooling.

To compare vendors on a list of top marketplace development vendors, buyers can start with Apptunix’s list.

Table 5: Cost and timeline for a Depop-style app by scope

Scope	Cost	Timeline	What the scope includes
MVP, one country	$45,000–$80,000	4–6 months	One-photo listing, feed, search, chat, in-app payments, shipping labels and admin console.
Full first version	$90,000–$160,000	6–9 months	Ratings, AI auto-listing, price suggestions, disputes, notifications and analytics.
Multi-region platform	$180,000–$350,000+	9–15 months	Visual search, multi-currency, international shipping, authentication and boosted listings.

The bill does not have to go to the start of the launcher. Cloud hosting, image storage, and CDN traffic increase as more and more items are added; moderation grows as there are more users, and the payment provider processes its fees for every order, which Depop’s model charges the seller. 

Plan for a maintenance and improvement line from the opening month, as a resale marketplace improves as it is released weekly instead of with a big launch.

Case Study: Namshi – Building a Trust-First Consumer Marketplace

Apptunix rebuilt Namshi’s mobile app and backend architecture to support the GCC’s leading fashion e-commerce platform and handle peak shopping traffic seamlessly.

The revamp delivered 2.4x faster checkout completion and a 36% increase in returning customers, improving the overall shopping experience and customer retention.

The upgraded architecture also handled the high-traffic White Friday sale without disruption, ensuring a smooth and reliable shopping experience during peak demand.

Conclusion: Build The Loop Before The App

Now, return to the 19-year-old on the floor in her bedroom. Now move back to the 19-year-old on the floor in her bedroom. She didn’t have to trust a stranger with a bank transfer, and she didn’t have to put one jacket up for sale in one picture and wait for a buyer to pay inside the app.

Each element of an app, such as Depop, is in place to keep that loop going: quick listing, a feed that keeps buyers coming back, payments that remain within the app, shipping with tracking, and security that makes that initial purchase feel secure.

The numbers don’t back up rapid construction. The secondhand market is projected to reach $393 billion by 2030; Depop has reported gross merchandise sales of around $1 billion worth of transactions in 2025, and supply is the biggest issue in resale, rather than demand. That’s why the initial plan for the launch is 200-300 sellers from 1 country, and that’s why speed is treated as a product, not a feature.

The same applies to money. Apptunix says that an MVP takes 45,000 – 80,000 Dollars and 4 – 6 months, and that AI listing, visual search, and boosts are reserved for future versions. The key to Depop’s buyer-fee model hinges on the availability of listings and on the duration of the payments within the app.

Once these two are sorted out, an app is no longer a clone, sellers remain, buyers come back, and Depop becomes a business, not a place to be a clone.
