Read the license termsWhat is Zero to Hundred?
Zero to Hundred is a license marketplace for working software. Builders sell licenses to software they built. A Buyer pays once for a non-exclusive, worldwide, perpetual license to use, modify, and deploy. Every sale is final.
Who is Zero to Hundred for?
It's for Builders who want to sell software they built, even if it has no users or revenue yet. It's also for Buyers who build software for clients and want a working starting point. A purchase is a license to the software and doesn't include a business, a customer list, or revenue.
How does buying work?
Watch the demo or walkthrough, then pay the price on the listing, with no extra Buyer fee. You get the source as soon as you pay, and every sale is final. If something is wrong, you have 24 hours from delivery to report a factual problem. The Builder's payout is held for at least 72 hours, so your report is reviewed before they're paid.
How does selling work?
Listing is free. Add a working demo or a walkthrough video, set a price, and describe what the software does and where it falls short. Then share the link from your listing or Seller profile. Buyers get the source as soon as they pay the listed price, and the commission comes out of your payout.
What does Zero to Hundred cost?
Listing is free, with no monthly fee. When a Buyer comes through the share link from your listing or Seller profile, the commission is 8% + $0.50. When they find your listing on the marketplace, it's 25%. Buyers pay only the listed price, and the commission comes out of your payout.

Buy the license
Payment releases the source. Configure, modify, and deploy your copy within the license terms.
What should I check before buying?
- Workflow
- Does the demo show the action your project needs with realistic inputs? Check difficult states alongside the attractive screens.
- Delivery
- Which source files, migrations, assets, and setup instructions are included? Ask which version runs the demo.
- Dependencies
- What runtime, accounts, API keys, paid services, and hosting must you supply? Unknown costs need an estimate.
- Rights
- Does the license fit your personal use, commercial product, or proposed client arrangement? Check third-party assets too.
- Responsibility
- Who will deploy, review security, update dependencies, restore backups, and operate the software after purchase?
Know what the license gives you
You buy a non-exclusive license to the software, with no company, customers, or revenue attached. You can use, modify, and deploy it for your own commercial or personal purposes, including in your own products and services.
You may not resell, relist, sublicense, or redistribute the software as a product. Resolve client handover and third-party asset questions before paying.
Read the current termsEvery sale is final
Source is delivered on payment. Report a factual problem within 24 hours of delivery. The Builder's payout is held for 72 hours, longer while a report is open, so a timely report can be reviewed before payout.
An upheld report is refunded from the held funds. This process isn't a trial or satisfaction guarantee. A disclosed limitation or change of plan isn't a valid report ground.
There's no separate Buyer platform fee on top of the listing price. Outside-service and operating costs remain yours. See marketplace pricing.
Questions about buying source code
What do I receive when I buy source code?
You receive the source and a non-exclusive, worldwide, perpetual license to use, modify, and deploy the software under the terms. Included files, documentation, and maintenance vary by listing. Read the Builder's disclosures before buying.
Am I buying a business?
No. You buy a license to the software, with no company, customers, or revenue attached. Other Buyers can license the same software too.
Can I use the software in a commercial product?
The terms allow use, modification, and deployment for your own commercial or personal purposes, including your own products and services. They restrict reselling, relisting, sublicensing, or redistributing the software as a product. Clarify any client source-handover arrangement before buying.
Do I need to know how to code?
Setup varies. Read the documentation, stack, and service requirements, and arrange technical help where needed. Buying source code doesn't provide managed hosting or someone to operate it for you. Budget for the work your team can't do itself.
Can I see the software work before buying?
Review the listing's working demo or walkthrough and its disclosures before checkout. A demo helps you assess behavior; it doesn't certify the code or replace your own review. Source delivery follows payment. Pre-purchase source access isn't promised.
Are hosting, updates, and support included?
Check the specific listing. Documentation and maintenance commitments differ, and you may need your own hosting, database, API accounts, and other services. Don't assume installation, lifetime updates, or ongoing support are included.
Do Buyers pay a separate platform fee?
No separate Buyer platform fee is added to the listing price. That doesn't remove outside costs such as hosting, paid APIs, setup, or maintenance. Review the listing, checkout, and current terms before paying.
What if there is a factual problem after purchase?
Report a factual problem within 24 hours of delivery. The Builder's payout is held for 72 hours, longer while a report is open, so a report can be reviewed before payout. An upheld report is refunded from the held funds. Sales are final; this isn't a trial or change-of-mind refund policy. Disclosed limitations aren't valid report grounds.
