Zero to Hundred vs SideProjectors
SideProjectors is cheaper. Their own help pages say it: there is no cost to submitting a project and they take no commission when one sells. What they do is put your project in front of people and pass on the emails. You handle the price, the payment, the contract, and the handover. Zero to Hundred charges 8% plus $0.50 on a sale you bring, or 25% on one we bring, and does those four things for you. It also sells a non-exclusive license, so the listing stays live and the same build can be sold again. If you are selling one project once, free is hard to argue with.

What does each one actually do?
SideProjectors is a classifieds board for side projects. You submit a project, it goes through a review, and once it is approved interested buyers contact you through the site and you get an email. Everything after that introduction happens between the two of you. Their front page describes the site as zero fees and completely free, and their help pages repeat it: no cost to submit, no commission on a sale.
Zero to Hundred is a license marketplace. A Buyer pays the listed price through Stripe and receives a non-exclusive, worldwide, perpetual license to use, modify, and deploy the software, including in their own commercial products. The source downloads the moment the payment clears. The Builder keeps the copyright and can license the same software to the next Buyer.
So the two sites answer different questions. Theirs is how do I find someone who wants this. Ours is how does the sale happen without either side taking a risk on the other.
What does it cost a seller?
| SideProjectors | Zero to Hundred | |
|---|---|---|
| Cost to list | $0. | $0. |
| Commission when it sells | None. They take no cut of the sale. | 8% + $0.50 on a sale you bring, 25% on one we bring. |
| Optional paid tiers | Membership at $3, $6, or $9 a month. The free tier is ad-supported and caps direct messages at 2 users a day. | None. |
| Who processes the payment | You do. Buyers contact you and you settle it between you. | Stripe, on the listed price, before anything is handed over. |
| Who delivers the source | You do, however you agree to. | The platform, automatically, the moment the payment clears. |
Take a $5,000 price. On SideProjectors the platform cost is $0 and you keep the whole $5,000, minus whatever you pay to move the money and whatever your time is worth negotiating it. Here it is $400.50 if you brought the Buyer through your own link, or $1,250 if the Buyer found your listing here. There is no version of that arithmetic where we come out cheaper on a single sale, and we are not going to pretend there is.
What does the fee buy?
Four things, and they are the same four things you would otherwise do yourself.
- The payment. Stripe takes the listed price before anything is handed over. No invoice, no wire, no wondering whether the transfer will reverse.
- The delivery. The source goes to the Buyer automatically when the payment clears. You do not add a collaborator, zip a folder, or agree who goes first.
- The license. Both sides get the same written terms on every sale. On a private deal that is a document one of you has to write.
- Selling it more than once. This is the part that has no equivalent on a classifieds board. The license is non-exclusive, so the listing stays live after a sale and the next Buyer pays the same price for the same build. A $5,000 project sold three times is $15,000, with $1,201.50 in commission if you brought every Buyer. Whether that happens depends on whether three people want it, which nobody can promise you.
How do the two models differ, line by line?
| SideProjectors | Zero to Hundred | |
|---|---|---|
| What the site is | A board where you post a project and interested buyers email you. | A marketplace that takes the payment and delivers the source. |
| What changes hands | Whatever the two of you agree on. Often the whole project, accounts included. | A license to working software. No revenue, no customers, no copyright. |
| How many times you can sell it | Once, in practice. The project has a new owner. | As often as it sells. The license is non-exclusive and the listing stays live. |
| How the price is set | An asking price, usually marked negotiable. | A fixed price. The Buyer pays it and the sale completes. |
| If the software is not what was described | Between you and the buyer. | Report it inside 24 hours and we review it before the payout releases at 72 hours. |
| What the seller does afterwards | Hands over and walks away. | Keeps the copyright, keeps the listing, keeps selling. |
What is SideProjectors better at?
Four things, and the first one is decisive on its own.
- Being free. No listing fee and no commission. On one sale of one project you keep more money there than here, and no amount of writing changes that.
- Costing nothing to try. Post it, see whether anyone emails, take it down. For a project worth a few hundred dollars that you are mostly curious about, that is the right amount of process.
- Selling things we do not handle. Domains, half-finished projects, and projects with revenue attached all have a home there. They also run co-founder searches and a showcase for work that is not for sale at all. We do none of that.
- Letting you negotiate. Most of their listings are marked negotiable and the deal is yours to structure. Prices here are fixed, which is faster and gives you less room.
Where is Zero to Hundred the wrong choice?
Five cases, stated plainly, because you will find them out anyway.
- You are selling one project once. If you want out of it and there is no second Buyer, you are paying a commission for repeatability you will never use. Post it on a free board.
- You want to sell the whole thing. Domains, accounts, users, revenue. None of that transfers here. A license covers the code and nothing else.
- You want to be the only one who has it. The license is non-exclusive by design. The same software is available to other Buyers, including your competitors. A private sale arranged off a classifieds board can be exclusive. This cannot.
- You want to try before you commit. There is no evaluation window at any price. The source is delivered the moment you pay, you have 24 hours to report a factual problem, and then the sale is final. The demo on the listing is the evaluation.
- You need deep inventory today. This marketplace is new and the catalogue is small. Their board has years of listings on it. That is a real reason to look there first.
Which one should you use?
Selling, and you want the project gone with no fee: SideProjectors. Free is free.
Selling, and the software is something more than one person could use: here. A non-exclusive license lets you sell the build repeatedly without giving up the thing you built, and the payment and delivery are handled.
Buying, and you want to negotiate directly with the person who built it, or you want the accounts and the domain too: SideProjectors.
Buying, and you want to pay a listed price and have the source in your hands a minute later: here. That is the case this marketplace exists for.
Common questions
Is SideProjectors free? Their help pages say there is no cost to submitting a project and no commission when one sells, and their front page says the same. They sell optional memberships at $3, $6, and $9 a month, and the free tier is ad-supported and limits you to direct messages with 2 users a day. Verify it yourself before you rely on it.
Can you list on both? Yes. Nothing here requires exclusivity. Be careful in the other direction: once you have sold a license here, you cannot honestly offer the same codebase to a private buyer as an exclusive sale without telling them.
Do you own what you buy here? No. It is a non-exclusive, worldwide, perpetual license to use, modify, and deploy. You cannot resell, re-list, sub-license, or redistribute it as a product. The Builder keeps the copyright.
Is money protected during a purchase? Not by escrow, which this marketplace does not use. The source is delivered immediately on every purchase. You have 24hours to report a factual problem, and the Builder's payout is held for 72 hours, so a report filed in time is reviewed before the money moves. On a private deal arranged through a classifieds board there is no equivalent, and one of you has to go first.
