Craft Marketplace
Not everything needs a contract. If you have already built something good, list it, and let anyone buy a copy. Listing happens in the game, browsing and buying happen here.
Why it is split across two places
Listing is done from inside KSP because that is the only place a craft can be read: its parts, its mass, its delta-v, the mods it depends on, and the blueprint render used as its thumbnail all come off the vehicle on the build stage. A browser cannot do any of that.
Browsing is done on this website because that is the only place it is pleasant: a filter sidebar, twenty five listings to a page, full size images and a proper search box beat anything drawn over a game at 1080p. The add-on’s market panel is the selling half only, and its browse button opens the site.
Selling
- 1
Open the market panel with the craft loaded
In the VAB or SPH, with the ship you want to sell on the stage.
- 2
Set a name, a description and a price
Prices run from 1 up to 10,000,000 KCoins. Everything else about the craft is read rather than typed: part count, distinct part types, mass, craft type, and the list of mods it came from.
- 3
It is posted and rendered
The listing appears on this website, which is where every craft is browsed and bought, and Discord is not involved. The thumbnail is the blueprint sheet the add-on renders, not a screenshot you have to remember to take.
A bonus for real designs
Listing a sufficiently complex craft pays a flat bonus of 300 KCoins, at most once a day. Complexity is counted in distinct part types and the threshold is more than twenty, because a booster made of three hundred copies of one girder is not a design worth paying for while a twenty five part probe is. Listing itself is never on a cooldown; only the bonus is.
Buying
A purchase debits your wallet, credits the seller, and gives you the craft file. You own it from then on, so re-downloading later costs nothing.
Craft bought here go through exactly the same install path as a craft delivered by a contract, so everything on Sharing Craft applies: flags, paint, fuel configs, part substitution and the CKAN modpack for whatever is genuinely missing.
The compatibility check
Every listing records the exact part names its craft uses. If you have uploaded your part catalogue from the game, the site compares that list against what you actually have installed before you spend anything, and again on the purchase result.
Compatibleclear | Every part in the craft resolves against your catalogue. |
Substitutablereported separately | Parts the add-on will swap for an equivalent on install. These do not count against compatibility, because warning about a problem that fixes itself on arrival is a false alarm. |
Blockinggenuinely missing | Parts with no local equivalent. The craft will still install, but it will be missing pieces until you add the mods behind them. |
Unknownnot a green light | No catalogue uploaded yet, or a listing that predates part tagging. Deliberately kept distinct from compatible, and never rendered as one. |
Advisory, never a gate
The check informs you; it does not stop you. You are allowed to buy a craft you cannot fully load, because installing the missing mod afterwards is a perfectly normal thing to do, and the add-on hands you a CKAN modpack to make it quick.
Sorting, filtering and finding things
Listings can be filtered by price, craft type, part count, mass, mods and free text search. Six sort orders are available:
Recommendedthe default | A discovery sort. New craft under fifteen days old, ranked by how fast their rating is climbing, then everything else by rating as a tail so a quiet fortnight does not empty the tab. |
Newestby date | Most recently listed first. |
Highest ratednet, all time | By community rating, without any time weighting. |
Best sellingby sales | The craft people actually bought. |
Priceeither direction | Low to high, or high to low. |
The mod filter has three modes, which do quite different things: required finds craft that use every mod you picked, allowed finds craft that use nothing outside your picks, and restricted excludes craft using any of them.
Rating and reports
Every craft carries a single community rating: each like is +1, each dislike −1, and the signed total is the number shown between the two buttons. Pressing the button you already chose takes your vote back.
A craft whose rating falls to −20 is taken off the marketplace automatically, without a moderator having to be awake for it. Nothing is destroyed: the seller still has the craft under My Uploads, everyone who bought it keeps their download, and a moderator can put it back. What the seller cannot do is relist it themselves while the rating is still that low.
Rating and reporting both require you to be signed in. An anonymous like is worth nothing, and an anonymous report costs a moderator their afternoon.
A report opens a ticket in your own server, so you can follow what happens to it, with the listing’s origin server named in the embed. The same listing cannot be reported twice by the same person to make a complaint look louder.
