Products

A few things we've shipped and keep running.

Each product below is built and maintained by ShellRick Tech and runs as its own independent service, with its own domain and infrastructure. Quiz Bru is a subscription product; RunYourNumbers and KeyForge are free, ad-supported tools. We keep the lineup deliberately small so each product gets ongoing attention rather than being left to drift after launch. If something breaks, it gets fixed, and if a feature stops earning its place, it gets removed.

Click through to any product below for more detail on what it does and who it's built for. Each one runs entirely on its own domain, so visiting a product takes you off shellricktech.co.za and onto the live site itself.

Quiz Bru is the one subscription product in the lineup; RunYourNumbers and KeyForge are both free and funded by advertising instead. All three are actively maintained: bugs get fixed and small improvements ship over time rather than the product being left alone after launch.
