A shared foundation. A product of your own.
This is Caylem, the web application we sell as source. The selected release of its pages, account and purchase flows, library and backend becomes the starting point for your own product.
What it is
Common foundations. Your product decisions.
Why Caylem exists, in plain terms.
We sell the application you are using. Its marketing pages lead to sign-in, checkout, a purchased-source library and a code browser. The release ZIP contains the code behind that flow, including the backend, shared components, emails and development tooling.
There are two starting points: a lightweight app for trying ideas without the connected services, and an app with Clerk, Convex, Polar, and Resend integrations. Choose the starting point that fits the work, then build the logic that makes the product useful.
The source is for creators building under their own names, agencies delivering client projects, and internal teams testing a specific idea. Keep it in a repository you control, change the brand, and take the product in your own direction.
Lyemac maintains Caylem. Each paid snapshot covers a selected source release. Review the release and changelog before purchase; after purchase, browse the source and download the ZIP from your library. Implementation, service accounts, and maintenance remain under your control.

Principles
What the foundation gives you
The handful of ideas every decision here comes back to.
The application itself
You get this web application at the selected release. The ZIP includes its source, setup guide and license; browse the purchased files in your library.
Room to start small
Try a focused UI in the lightweight app, or start with connected services when the project needs accounts, data, and purchases.
Documented for contributors
Repository instructions and focused skills give developers and coding agents an architecture map. Changes still need review and tests.
A consistent toolchain
Bun, Turborepo, strict TypeScript, and Biome give the applications and shared packages a common development workflow.
Connected product foundations
Clerk identity, Polar purchases, Convex data, and Resend email provide a starting integration path. Your product rules and service configuration are still yours to build.
Yours to own
Download the selected release, change the code, and keep using it under the included MIT license. Preserve the required notices.
Take this application home as source
Review the version and price, download the application ZIP after purchase, and follow the README to make it yours.
Choose a single release or unlimited updates while subscribed. Hosting and service usage are separate.
