What kind of code can I sell?

Anything you can package: NuGet packages (compiled or source), .zip source bundles, Blazor components, class libraries, templates, starter kits, scripts, even ebooks and documentation. If it's a file, you can sell it. The platform specifically optimises for .NET NuGet packages with a built-in private feed — buyers install with one dotnet command.

How does the NuGet feed work?

Each purchase generates a unique token. That token is embedded in a personal NuGet feed URL we email to the buyer. They run dotnet nuget add source with that URL and install your package via dotnet add package. The feed only shows packages they've actually paid for — other sellers' products are invisible. Refunds invalidate the token instantly.

What does it cost to sell?

No monthly fees, no setup charges, no listing fees. You pay only Stripe's standard processing fee plus a small platform commission per sale. You connect your own Stripe account via Stripe Connect and receive payouts directly — we never hold your money.

How is piracy handled?

FastLinkIt uses an honour-system licensing model, which is what most successful indie .NET libraries (MudBlazor Pro, Radzen, etc.) do. Every purchase creates a licence record and the buyer receives a unique licence key. No runtime phone-home, no online activation, no dev friction. Legal teeth come from the purchase record, not runtime code.

Can I sell source code too?

Yes. Upload a .zip of your source, price it typically 3× the compiled version, and the same delivery flow applies — buyers get a tokenised download link in their post-purchase email. For source-only products skip the NuGet feed entirely; the direct-download link is all they need.

What about bundles and multiple products?

Create a 'bundle' product linked to multiple files, or run several products through the same shop with a discount code. The NuGet feed automatically shows all packages a buyer has access to — bundle purchases light up every included component, single purchases show only one.

How do my buyers actually install?

The post-purchase email contains two copy-paste options: Option 1 (recommended) is two lines — dotnet nuget add source then dotnet add package. Option 2 is a direct .nupkg download button for air-gapped environments or CI systems that can't reach the feed. Both options work identically for buyers.

Private NuGet feed — the install UX buyers actually want

Every purchase gets a personal, tokenised NuGet v3 feed URL. Buyers copy one line and install your package. Works with Visual Studio, dotnet CLI, Rider, and every NuGet client. The token is invisible to other buyers — each customer sees only the packages they've actually paid for.

Full NuGet v3 protocol — service index, flat2, registration
Bundle purchases surface every included package
Source licences get a direct-download link instead
Token rotation and revocation built in
Refund → feed access revoked automatically

Honour-system licensing — no dev friction

Every purchase generates a licence key and a purchase record. There's no runtime phone-home, no online activation, no air-gapped-env pain. This is what MudBlazor Pro, Radzen, and every successful indie .NET library does — and it's what buyers expect in 2026.

Legal teeth come from the Stripe receipt and the licence record in your dashboard, not from runtime code that annoys paying customers. Piracy is vanishingly rare in the .NET indie market — awareness is your real problem, not copy-protection.

Per-developer perpetual licence (default)
Team / site / white-label upgrades if you want them
Time-limited licences for trials / subscriptions
Licence keys emailed to buyers, viewable in their dashboard
Refund auto-revokes feed access within seconds
