SaaS marketplace solutions are platforms that you don't generally "own", but get access to for a monthly fee (as high as $1,500/mo), sometimes with a sales/per-transaction fee on top.
MultiMerch is a self-hosted, white label marketplace platform, which means you purchase it outright, get access to the complete source code and fully own it. Both options have their benefits and drawbacks.
With MultiMerch, you completely own the source code, which means you can modify all parts of the platform down to the last element. Since you host the MultiMerch platform yourself, you also have the complete control over the data and the processes. However, it also means you need at least a little technical experience to build a marketplace with MultiMerch.
We usually recommend SaaS marketplace platforms to individual entrepreneurs building simple marketplace MVPs who don't want to deal with the technical aspects of running a marketplace.
Additionally, Sharetribe is primarily designed for service marketplaces and bookings, while MultiMerch is first and foremost a product marketplace solution.
