Bring your own app.We host and serve it.
Custom Apps let you upload your own compiled web app, single-page app, WASM or WebGL build and sell access behind a paywall or a subscription. We do not just link to it, we host and serve the bundle itself, securely and per user through an authenticated proxy, all under your own brand and your own domain.
Built with the web stack you already use
We serve the app itself, not a link to it
An embedded tool is something that lives somewhere else and shows through an iframe. A Custom App is different. You upload your actual build and the platform hosts and serves it from your own deployment.
Every request goes through a secure per-user proxy route that checks the visitor is signed in and has an active purchase before a single file loads. There is no third-party host in the middle and no public URL leaking your app.
If you have already built something in a framework that compiles to a web bundle, a SPA, a WASM module or a WebGL experience, you can put it behind a paywall here.
Served per user, behind a paywall
The app is only served to customers who have access. A buyer signs in on your domain, pays through Stripe, and the app loads inside their authenticated session.
Access is tied to the account, just like a course or a download, so you control exactly who can run your app and for how long.
Sell it as a one-time purchase or as a recurring subscription, whichever matches how your app delivers value.
Keep your logic on the server
A Custom App does not have to run everything in the browser. You can run server-side logic, in JavaScript or Python, so the code that matters never ships to the client.
Your algorithms, pricing rules, model calls or any proprietary logic run on the server and return only the result. The visitor sees the output, not the source, so your intellectual property stays yours.
The app calls your server-side scripts through the same authenticated, per-user proxy that serves the build, so only customers with access can trigger them.
What a Custom App can be
If it compiles to a web build, it can be sold here.
Single-page apps
Upload a compiled SPA and serve it per user behind a paywall on your own domain.
WASM modules
Upload a WebAssembly build and serve it to paying customers as a hosted product.
WebGL experiences
Serve an interactive WebGL or 3D experience to paying customers, hosted on your deployment.
Hosted per user
We host your bundle and serve it through a secure proxy on your own isolated deployment, not a public link.
Access control
Access is tied to the customer's account, so only buyers can launch the app.
One-time or subscription
Charge once or bill monthly or yearly through Stripe, with payouts to your own account.
On its own domain
Serve your app on its own dedicated custom domain, separate from your store, with single sign-on so a buyer signed in on your store is recognized there, all under your brand.
Server-side logic
Run JavaScript or Python on the server so your core logic never ships to the browser, keeping your app's IP private.
