Best AI App Builder for a Marketplace (2026): Who Can Actually Pay a Seller?

Asking whether an AI app builder has payments tells you nothing about whether it can run a marketplace. One collects money into your account, the other has to move it past you to a seller. Eight builders compared on documented marketplace paths, Stripe Connect and the money split.

Quick answer (September 2026). Asking whether an AI app builder "has payments" tells you almost nothing about whether it can build a marketplace. Built-in payments collect money into your account. A marketplace has to move money into somebody else's account, minus a cut. That is a different Stripe product, Stripe Connect, and a different legal position. On that axis the eight builders split three ways. Bubble logo Bubble is the only one with a dedicated marketplace guide that names Stripe Connect and walks the three-party money split. Base44 logo Base44 documents it, but as a prompt you type, flagged Advanced, not as a feature. Lovable logo Lovable, Bolt.new logo Bolt.new, Replit logo Replit, Softr logo Softr, v0 logo v0 by Vercel and Webflow logo Webflow document a single-merchant model only, and three of them document no payments layer at all.

That is not the same as saying six builders cannot do it. Most of them will run whatever server-side code you write. The finding is that on seven of eight, the marketplace is a thing you build around the payments feature rather than with it.

Every comparison on this question is written by a builder

This is worth saying before the table, because it is why the table exists.

Search for the best AI app builder for a marketplace in September 2026 and Google returns 129 results. Eight organic results come back. Seven of the eight are published by a company selling an app builder, and four of those rank themselves first on their own page. The one page that is specifically about marketplaces is a vendor comparison of "the 7 best AI app builders" in which that vendor is number one. The single result that is not vendor-owned is a Reddit thread in r/nocode asking the question, and it is about no-code builders rather than AI ones.

So the honest starting position is that nobody independent has compared these tools on this job. We have no marketplace product to sell, and the scoring below is sourced entirely to each vendor's own published documentation, read on 17 September 2026, with every URL in the Sources block.

What a marketplace needs that a normal app does not

A marketplace is not "an app with payments bolted on". Four things change, and each of them is decided before you write a line of code.

1. The money has to land in a third party's account. In a normal app the buyer pays you. In a marketplace the buyer pays, the seller receives most of it, and you keep a fee. Bubble's own documentation states the split plainly: Stripe retains its transaction fee, a portion is retained in the seller's Stripe account, and another portion is transferred to the marketplace owner's account. Stripe's product for this is Stripe Connect, and it is a separate integration from ordinary Checkout.

2. Onboarding a seller is an identity event, not a signup. Because a seller receives money, the platform inherits a verification duty. Base44's docs say this out loud in their caveat: Stripe Connect "may require additional setup or approval from Stripe". A signup form does not cover it.

3. Two populations of end users share the same rows. A seller sees their own listings and their own earnings. A buyer sees every seller's listings and nobody's earnings. That is neither teammate permissions nor simple per-user isolation, and it is the hardest part to retrofit. We cover the underlying mechanics separately in multi-tenancy across AI app builders.

4. Somebody is legally the merchant. This is the one that quietly disqualifies a default path, and it is covered below.

Every "not documented" above means an absence in that vendor's published documentation, not a proven absence in the product. Two are stated in the stronger form: Bolt.new's complete published index is 93 entries and Webflow's complete developer index is 71 entries, and both were read in full with zero marketplace, Connect, payout or seller entries.

Bubble is the only one that treats this as a first-class job

Bubble publishes two pages on it: one on building a marketplace and a second on how to structure the database for marketplace apps. The first names Stripe Connect and describes it as Stripe's solution for platforms to "manage payments and payouts for multiple sellers or service providers within their ecosystem". The second is about modelling, and it is the more useful of the two, because it works through the unglamorous decision of how a listing points at its seller and what happens to that link when the seller account is deleted.

Bubble also does something none of the others do: it attaches a disclaimer stating that the guidance is not legal advice and that selecting a compliant payment platform is the builder's responsibility. That is a small thing that tells you the documentation was written by someone who has seen this go wrong.

One caveat on the numbers. Bubble's documentation index contains 32 mentions of "marketplace", and only two of them are about building one. The other thirty are Bubble's own plugin and template marketplace, which is a completely different sense of the word. If you are grepping vendor docs yourself, that distinction will bite you.

Base44 documents it as a prompt, which is a real answer

Base44's payments documentation includes an entry titled "Build a simple marketplace (Advanced - Stripe Connect)". It is not a feature page. It is a block of text you paste into the chat: register users as sellers, let them connect their own Stripe accounts, route each payment to the correct seller, optionally take a platform fee, and show each seller their earnings and payout history.

Treating that as second-best would be wrong. It is a documented, specific, end-to-end path, and it is more honest than a feature checkbox because it admits the work is generative rather than configured. The caveat attached to it is the important part: Connect "may require additional setup or approval from Stripe".

But Base44 carries a trap worth naming. It has two payment surfaces, and the default one is not the marketplace one. Base44 Payments powered by Wix is the built-in option, and in that surface "payouts" means payouts to you. The marketplace path runs through Stripe instead. If you evaluate Base44 by clicking the built-in payments option, you will conclude it cannot do marketplaces, and you will be wrong.

Lovable's default path is structurally the opposite of a marketplace

Lovable's built-in payments let you use Paddle or Stripe. Its own comparison table describes Paddle as a Merchant of Record, and spells out what that means: when a provider acts as MOR "they are legally the seller", they calculate and remit taxes, and "you receive payouts after fees".

Read that against requirement four. In a marketplace, your sellers need to be the sellers. A Merchant of Record model puts the payment provider in that position instead, which is excellent for shipping a SaaS subscription and structurally wrong for a two-sided marketplace.

Across Lovable's 214-entry documentation index and both of its payments pages, the literal phrase "Stripe Connect" appears zero times. There is a great deal of the word "connector", which is Lovable's own integrations feature and a different thing entirely.

Bolt.new, Replit and Softr: the convenience is the constraint

These three are grouped because their documentation says the same thing in three ways.

Bolt.new logo Bolt.new advertises "automatic synchronization of products from your Stripe dashboard". That is genuinely convenient and it is single-merchant by construction: in a marketplace the products come from your sellers, not from your dashboard.

Replit logo Replit is blunter still. Its payments guide, built around taking a deposit and charging a balance later, states that "Replit handles payments through Stripe, you don't write any Stripe code yourself". For a booking flow that is a selling point. For Connect it is the whole problem, because the path that writes the Stripe code for you is the path that will not write Connect.

Softr logo Softr has exactly one page in its 322-entry index that mentions creating a marketplace, and the answer is Gumroad: you put a Buy Now button in your Softr app that opens the corresponding Gumroad product link. The money never touches your application, and there is no seller onboarding, no fee split and no payout ledger. It is a link to somebody else's checkout.

All three will still run code you write, Bolt.new and Replit through ordinary server-side functions. The finding is about the documented path, not the ceiling.

v0 and Webflow have no payments layer to compare

v0 logo v0 by Vercel has a 32-entry documentation index with no payments, ecommerce or marketplace pages at all. That is not a gap so much as a category difference: v0 generates a codebase you deploy on Vercel, so Connect is exactly as available to you as it is in any other project, and exactly as much work.

Webflow logo Webflow's complete developer index runs to 71 entries covering the Data API, Designer API, Browser API, Code Components, Webflow Cloud, DevLink, Flowkit, Apps, MCP and the CLI, with zero payment, ecommerce, marketplace, payout or seller pages. Webflow Ecommerce exists as a product, and it is a store that sells your own products, which is the single-merchant model again. Webflow Cloud, which deploys Next.js and Astro applications, is where anyone would actually build this.

What this comparison deliberately does not cover

Three things a real marketplace operator cares about are missing here on purpose, because the eight vendors do not document them at a comparable level and a table built on that would mislead: dispute and chargeback handling when the money has already been split, tax reporting obligations to sellers, and payout timing. We also quote no plan prices anywhere, because prices move faster than this page will, and the plan gate is the durable part.

One stated gap in the research. Webflow's help documentation returned HTTP 403 to us on 17 September 2026, so the Webflow reading above is based on its complete developer index and its public ecommerce page. We have not read the Ecommerce help articles, and we are not claiming an absence there.

The verdict, September 2026

Pick Bubble if the marketplace is the product. It is the only one of the eight that documents the job end to end, names the payment architecture, and separately explains the data model. That combination does not exist anywhere else on this list.

Pick Base44 if you want to reach a working prototype fastest and are comfortable that the marketplace arrives as generated code rather than as a feature. Its documented Connect prompt is specific enough to be useful, and its own Advanced flag is fair warning.

Pick Replit, Bolt.new or v0 if you are willing to treat the marketplace as ordinary application code and want the builder to stay out of the way. You get a real server-side runtime and you write Connect yourself.

Do not start from Softr or Webflow Ecommerce for a multi-seller marketplace, and be careful with Lovable's built-in payments specifically: the Merchant of Record route is a good product doing a job that is not this one.

The general rule underneath all of it: a payments feature is built to get money to you. A marketplace is defined by money going past you. Every difference in this table follows from that one sentence.

Frequently asked questions

Which AI app builder is best for building a marketplace in 2026?

Bubble, on the evidence of published documentation. It is the only one of the eight builders compared here with a dedicated marketplace guide, it names Stripe Connect and describes the three-party money split, and it publishes a second page on how to structure the database for marketplace apps. Base44 is the strongest runner-up because it documents a specific Stripe Connect prompt, though it arrives as generated code rather than as a configured feature.

Why is built-in payments not enough for a marketplace?

Because built-in payments are designed to collect money into your account. A marketplace has to move most of each payment into a seller's account and keep a fee, which is a different Stripe product called Stripe Connect. Bubble's own documentation describes the split: Stripe keeps its transaction fee, a portion stays in the seller's Stripe account, and a portion transfers to the marketplace owner. A standard checkout integration does none of that.

Can Lovable build a marketplace?

Nothing stops you writing Stripe Connect code in a Lovable edge function, but its built-in payments path points the other way. Lovable offers Paddle as a Merchant of Record, and its own documentation states that when a provider acts as Merchant of Record they are legally the seller and you receive payouts after fees. In a marketplace your sellers need to be the sellers. The phrase Stripe Connect appears zero times across Lovable's 214-entry documentation index and both of its payments pages.

Does Softr support marketplaces?

Not in the multi-seller sense. The only page in Softr's 322-entry documentation index about creating a marketplace covers Gumroad, and the pattern is a Buy Now button in your Softr app that opens a Gumroad product link. The payment happens on Gumroad, so there is no seller onboarding inside your app, no fee split and no payout ledger. Softr's own Stripe Checkout integration collects payments to a single merchant.

What is Stripe Connect and why does it keep coming up?

Stripe Connect is Stripe's product for platforms that pay out to multiple third parties. It handles connected seller accounts, routing a payment to the right seller, taking a platform fee and running payouts. It is the component that distinguishes a marketplace from an ordinary store, and it brings an identity-verification duty with it. Base44's documentation notes that Connect may require additional setup or approval from Stripe.

Do Replit, Bolt.new and v0 rule out marketplaces?

No. All three give you a real server-side runtime, so you can integrate Stripe Connect as ordinary application code. What none of them documents is a marketplace path. Bolt.new synchronises products from your own Stripe dashboard, which is single-merchant by construction, and Replit's guide states that Replit handles payments through Stripe so you do not write any Stripe code yourself, which is precisely the path that will not write Connect for you.

What does this comparison not tell me?

Three operator-level questions are deliberately excluded because the eight vendors do not document them at a comparable level: dispute and chargeback handling once a payment has already been split, tax reporting obligations to your sellers, and payout timing. No plan prices are quoted anywhere either, because prices change faster than this page and the plan gate is the more durable fact. Webflow's help documentation returned HTTP 403 on 17 September 2026, so no absence is claimed there.

AI App Builder Multi-Tenancy (2026): Per-User Is Not Per-Tenant

Every AI app builder can show a user their own rows. That is not multi-tenancy. Multi-tenancy is two colleagues at the same company seeing the same records and nobody at a rival company seeing any of them. Only one of eight builders documents organisation-scoped access as a supported pattern.
