Build from here. Make it yours.
The business you want to start. The client project you want to win. Give it a working foundation. Caylem is this application, sold as editable source, with sign-in, checkout, a backend and reusable pages already connected. Add the part only you can build.
Loading the release file structure…
Sell your software. From South Africa.
A starter that assumes you can open a standard Stripe account leaves South African builders with more work. Caylem includes Polar checkout: a payment route for eligible software and digital products, with South Africa on its supported payout list.
Polar approval, identity checks and product rules still apply. Agency service invoices, physical goods and local EFT need a suitable payment route of their own. Paystack, PayFast and Yoco integrations are not included.
Sell your software through Polar
Polar acts as the merchant of record and pays sellers through Stripe Connect Express. This is a different route from opening a standalone Stripe Payments account.
Start with a purchase flow you can use
Catalog, one-time checkout and purchased access are connected in the source. Configure your own Polar account and adapt delivery to your product. Recurring billing needs additional implementation.
Buy your starting point in rand
Review the source price in ZAR before checkout. Keep the code for your own products and client projects under the included MIT licence. Hosting and service fees are separate.

Less repeat work. More room for your business.
Your budget, evenings and delivery capacity matter. Start with common systems connected, then use your skills on what customers will pay for.
Know the source price in the currency you budget in.
Comparing a dollar price with a rand project budget adds another calculation before you can decide what the build will cost.
See the source price in rand before you commit. Buy the selected release once and use it for your own products or client projects under the included MIT licence. Budget separately for the services you run.
A source purchase priced in rand. No converted estimate.
Build on the foundation
Put your next build session to work.
More time on the customer problem. A common starting point for your team. Source you can keep developing as the business grows.
Your next product can start here.
The tool a local business keeps asking for. The digital product you want to sell abroad. The client brief your team knows how to solve. Each deserves more of your time than another round of setup.
Start with working source, reusable pages and connected services. Build the workflow, find the customers and keep improving it in your own repository.
Built here. Under your own name.
