The Studio Premise
Meaningful software doesn’t require a hundred people—it starts with one curious maker obsessed with shipping tools that genuinely work.
What We Build
Built with curiosity. Made with purpose.
OneMakerLab focuses on software that respects your attention—whether it is a specialized micro-SaaS, a developer utility, or an interactive experiment.
Developer Tools
Tools that simplify workflows and make building software more enjoyable.
Fast, keyboard-friendly utilities and sharp primitives built out of real daily engineering bottlenecks.
Experiments & Ideas
Creative explorations, prototypes, and projects worth trying.
Public sandboxes and weekend curiosities that test browser APIs, tactile interfaces, and generative mechanics.

About the Maker
O n e p e r s o n . M a n y i d e a s .
OneMakerLab is an independent software studio founded by Leandro Serrano around a simple belief: meaningful products can start with one curious person and a willingness to build.
It is not a consulting agency or a venture-chasing startup. It is a personal workshop for shipping useful web software, developer utilities, and honest digital experiments under one roof.
