Zero to Hundred

Sell your codebase more than once.

The marketplace to buy and sell source code. List your software once, sell non-exclusive licenses, and get paid every time it sells.

Free to list. You keep the copyright.

List it once, and watch it collect cash
not dust.

Shipping it was one job. Selling it is another.

You have working software and no distribution. Every sale means finding someone who needs it, proving it runs, and giving them a reason to trust a stranger enough to pay. Zero to Hundred does that part.

Build it.
Ship it.
Sell it.

Ship working software

You built and shipped working software. Most running software can sell here. Micro-SaaS, AI agents, internal tools, scripts, browser extensions, templates, and API integrations. If it runs and does something real, it can sell.

List your codebase for sale

Create a listing in minutes: add a working demo or a walkthrough video and set your price. You keep the copyright and sell a non-exclusive license, so the same codebase can sell to as many Buyers as want it. Listing is free, and you can sell the same software anywhere else.

Sell to Buyers, payment first

When a Buyer pays, payment is captured before any source code is released. You never chase an invoice. The Buyer receives the code immediately.

Get paid, then sell it again

Your payout lands in your connected account. Because the license is non-exclusive, your listing stays live after every sale. List your codebase once and keep selling it to new Buyers.

List from anywhere.

Create a software listing draft from Claude Code, Cursor, or another compatible local MCP client. Review the details in the listing wizard before publishing.

Payment is captured before the code is delivered.

A purchase is a binding commitment. The payment is captured before any code releases. The Buyer gets the code immediately and has 24 hours to report a problem. A report must be factual. The grounds are misrepresentation, a bug that stops the software working, or other factual grounds.

Delivered on payment.

Payment and delivery happen in one step. The Buyer has the code in hand the moment the sale clears, at every price.

Paid before release.

Buyers pay upfront. A purchase is a binding commitment, and the payment is captured before any code releases.

Report window.

Every sale carries a 24-hour report window. Grounds are factual. Misrepresentation, a bug that stops it working, or other factual grounds.

Checked before it lists.

A Builder can connect GitHub, and every listing carries a working demo or a walkthrough video. No demo, no listing.
