The marketplace builder for first transactions in days

Prometora is a marketplace builder for founders who want real transactions, not a prototype. Describe your idea and get a full multi-vendor marketplace: listings, Stripe payments with automatic seller payouts, shopping cart, messaging, reviews, and seller subscriptions, on your own domain. Start from a prompt or a template, customize everything with no code, and take your first transactions in days. A popular Sharetribe alternative with live marketplaces in rentals, services, antiques, and B2B.

I'm Rasmus, founder of Prometora.
I've built 4 online marketplaces myself, and I run a YouTube channel focused on marketplace building.
I kept seeing non-technical founders struggle to launch marketplaces, even with no-code tools. Template platforms like Sharetribe get you a marketplace, but customizing beyond the template gets expensive or needs developers. General AI builders like Lovable can generate an app, but you end up rebuilding all the marketplace plumbing yourself.
So I built Prometora - a marketplace builder where you describe your idea and get a complete multi-vendor marketplace: listings, Stripe payments with automatic seller payouts, shopping cart, messaging, reviews, seller subscriptions, and your own domain.
The difference is the built-in "system pages" every marketplace needs: create-listing page, seller dashboard, all-listings page, listing detail page, and more. They're production-ready from the start, so you customize instead of rebuild - and take your first transactions in days.
Today, live marketplaces run on Prometora in rentals, services, antiques, and B2B.
I'd love your feedback! And if you want to test it, there's a free trial to get you going fast.

Nice — the 'built-in system pages so people don't forget what a marketplace actually needs' framing is sharp. I'm a researcher studying where non-technical founders get stuck turning an idea into a real product, and your whole pitch is basically that observation. Genuinely curious: before you added those system pages, what was the single most common thing your early users tried to build and just... couldn't? Was it the two-sided listing flow, payments, or something earlier like just not knowing what to ask the AI for? Would love to compare what you're seeing with what I'm hearing.
Smart idea! Creating an entire app from a prompt is neat, but as a layman, it's quite easy to forget (or not know) what features that a marketplace app must have – so this really mitigates that risk. I wonder what other general app ideas could do with that type of framework?

@kmanderuk Hi Keith! Thanks so much, really appreciate that!
And you’re right: most people don’t know all the features a real marketplace needs, so the structure helps remove that uncertainty. That's the idea behind Prometora - so you get best of both world (Prompting + some structure).
This same approach could definitely apply to other types of apps too. For example:
- E-commerce stores (single-seller), Auction platforms, Booking & appointment apps, Membership/subscription platforms, etc
Marketplaces were the best starting point because they are super complex , but Prometora can absolutely expand into other app types over time.
@rasmus_sorensen I like the idea of using this for creating bespoke booking apps – probably a much more common use case for the typical SME – which could be built and put into real word use immediately. Whereas marketplaces are real tough not only to build but also to get started and operate.

maybe i’m missing something here, but what anyone need to create a marketplace? sounds like creating a social network
Prometora
@daniel_chepenko Hi Dany , there are many marketplace founders out there with ideas, but struggling with actually building it.
Also, a marketplace is not like a social network. It can sound similar on the surface, but creating a marketplace is very different from creating a social network.
A marketplace needs a lot of functionality that’s specific to enabling transactions between buyers and sellers, such as:
-Listing creation
-Search + filters
-Messaging between users
-Booking or purchasing flows
-Payments + payouts (e.g., Stripe Connect)
-Reviews, disputes, availability calendars, etc.
-and many more.
A social network is mainly about user-generated content and connections, while a marketplace needs the entire infrastructure behind it.
@rasmus_sorensen love how you keep your UI simple, who would you point out to benefit the most from the platform? Like a target audience and use cases
Prometora
@pasha_tseluyko Hi Pavel,Thank you for the question!
The people who benefit the most from the platform are marketplace founders , anyone who has an idea for a marketplace (think Airbnb, Rover, etc.) and wants to get it up and running quickly without spending months on development.
I wanted to love this... however it's a bit deceptive that I can type my prompt but then need a subscription without knowing if this site will work. There's plenty of other sites like this (not as niche) like Base44 where I can generate a working website for anything with a lot of free prompts. Hope all the best anyhow!

@oj_designz Hi OJ, thanks for the comment! I have multiple videos showing how it works. Check the Frontpage and on my YouTube channel. Thanks!

Wow! This is amazing.
Are the code generated for payments and auth secure?
Prometora
@chilarai Thank you for the question Chilarai,
Yes, because those are part of the "system pages", so they aren’t generated from prompts.
For payments, the platform uses Stripe / Stripe Connect, and for authentication it uses Clerk. Both handle the sensitive parts on their end and follow industry-standard security practices.

@rasmus_sorensen That's great! It's a brilliant idea. Keep it up
