This is less of an edge case than it sounds. The terms attached to a purchase shape what you can safely plan to do with a project months down the line, whether that means expanding it internally, bringing on a partner, or eventually trying to sell something built on top of it.
Source code included does not mean unrestricted rights
Buying software with source code included means you receive the files and can read, run and modify them. It does not automatically mean you can resell the project as your own product, redistribute it to others, or claim the original build as something you created from scratch. What you can and cannot do is set entirely by the licence attached to the listing, not by the fact that you have the files in hand.
This is a distinction worth sitting with, because it runs against the intuition that having a file means you can do anything with it. Software licensing has always worked this way, for code written by a person and code written by an AI coding tool alike, and a marketplace purchase is no exception to that general rule.
Single-site licences, explained plainly
The most common structure is a single-site licence: the code is yours to use and modify for one project or deployment, but the seller retains the underlying copyright and can sell the same project to other buyers separately. This is similar in spirit to buying a commercial font or a stock photo licence, where usage rights are granted without the buyer owning the underlying creative work outright.
Some listings offer broader licences for an additional cost, including extended or exclusive rights for buyers who specifically need them. These are the exception rather than the default, so it is worth checking explicitly rather than assuming a broader licence applies just because the price felt high enough to justify one.
What the seller keeps after a sale
Sellers typically retain the copyright to the original codebase, the right to continue selling it to other buyers, and the right to keep developing and updating it as its own product. This is why the same listing can appear to sell more than once on a marketplace, since each sale grants a licence rather than transferring sole ownership.
From a seller's perspective, this is what makes a single well-built project capable of generating income repeatedly rather than only once, which is part of why documentation and ongoing quality matter so much to a seller's long-term earnings, not just to the first sale.
What a buyer can safely rely on
• The right to run and use the software for your own project
• The right to modify the code, including with your own AI coding tool
• A setup guide and, usually, a defined support period after purchase
• Clear terms stating whether resale or redistribution is permitted
Why this matters more for AI-built code specifically
With traditionally commissioned software, ownership terms are usually negotiated directly between client and developer before any code is written. On a marketplace, the licence is fixed before you ever see the listing, which makes reading it before purchase more important, not less, since there is no negotiation happening in the background on your behalf.
Checking licence terms before you buy source code online
The practical takeaway is simple: read the licence terms on a listing the same way you would read them on any other purchase with downstream implications, before paying rather than after. A clearly stated licence is itself a signal of a well-run marketplace, since it means the question has already been thought through rather than left for a dispute later.
Listings on the Vibe Coded AI Marketplace state their licence terms directly on the product page, so this is something you can confirm before committing rather than discovering after the purchase is already complete.
What to do if licence terms are unclear
If a listing's licence terms are vague or missing entirely, the safest move is to ask before buying rather than assume the most favorable interpretation. A seller who takes their listings seriously will have a straightforward answer ready, and a seller who cannot explain their own licence terms clearly is a signal worth weighing on its own, separate from everything else the listing might offer.
It is also worth keeping a copy of the licence terms as they appeared at the time of purchase, since listing pages can be updated over time. A simple screenshot or saved copy avoids any ambiguity if a question comes up months later, well after the original listing page may have changed.
Treating ownership as part of the purchase decision
Licence terms rarely decide whether to buy a particular listing on their own, but they belong in the same evaluation as the audit score and the stack, not as an afterthought read only once a dispute makes it necessary.
Owning a copy of the code and owning the software outright are not the same thing, and the gap between them is defined entirely by licence terms most buyers skim past without reading closely. Understanding what you are actually buying, and what the original builder keeps, is a five-minute read that prevents a much longer conversation later if plans change.
