Transferslot is one of the early side project marketplaces. It started in 2017 as a place to sell projects that had been featured on Product Hunt, then opened up to any founder in 2018. Its approach is selective: every submission is reviewed so that only good quality projects reach its community of buyers.

How it works
You submit your project with a description, metrics, tech stack and asking price. Transferslot reviews it, and if accepted, publishes it to the marketplace and promotes it to buyers. Interested buyers get in touch, and you negotiate the deal. When it launched its second version, the team said selling was entirely free; more recent guides describe a free listing period combined with newsletter promotion. Check the current terms on the site before submitting.
What sells
Side projects with users or a little revenue, small SaaS tools, apps, marketplaces and content sites are typical. Because listings are reviewed, unfinished or very rough projects may be turned away, while polished small products with a clear use case stand out. Buyers are often makers looking for a head start or a project that fits their skills.
Preparing a strong listing
Explain what the project does, who uses it and why you’re selling. Share honest numbers: users, traffic, revenue and running costs. List exactly what’s included, such as the domain, code, design files and social accounts. Good screenshots and a short demo video help buyers understand the product quickly.
Closing the deal
Agree the price, payment method and handover steps in writing. Use escrow for anything beyond a small amount, and transfer assets only once payment is secured. Offer a short support period after the sale to help the buyer take over hosting, code and accounts.
Is it still active?
Transferslot has been around since 2017, but small marketplaces change. Before listing, check recent listings and sales on the site to confirm it’s active and that buyers are engaging. If it looks quiet, list in parallel on another marketplace.
Getting started
Polish your project, prepare clear numbers and submit it for review. Share your listing on your own channels to bring extra buyers.
Pricing a side project
Most side projects sell for modest sums, from a few hundred dollars for early code to several thousand for products with users and revenue. Buyers compare your price with the cost of building the same thing, so stress what’s hard to recreate: an aged domain, search rankings, real users, integrations or a polished design. If you have revenue, show it from the payment provider rather than in a screenshot.
Spreading your reach
Small marketplaces work best combined with your own promotion. Share the listing on X, LinkedIn, Indie Hackers and relevant communities where self-promotion is allowed. Mention the one thing that makes the project worth buying in the first line, since most people only skim.
Who buys side projects
Most buyers are developers and marketers looking to skip the build phase. Some want a product to grow, others a codebase to reuse or a domain with history.
Owen’s take
Transferslot was one of the first places to sell side projects, and its review step keeps quality up. I’d use it as one channel among two or three for a small project, rather than the only one, and check it’s active before investing time in a listing.
Who it suits
It suits makers with polished small projects and buyers looking for reviewed listings. It suits less well rough, unfinished projects or larger businesses needing full deal support.
