Behind the Project

Good Tool is a side project by Trevor Loucks focused on fast, practical calculators and tools. It is part of the same operating network as Dynamoi and Hardly Creative.

Tech Stack

Built with TypeScript and React for reliable, responsive calculator experiences. The platform is moving toward static-first delivery so pages can load quickly and keep infrastructure costs low. We integrate with Google AdSense and Microsoft Advertising to support our free services.
