Tools that respect your privacy.
Built with care.
I'm Sarah Frota. I build tools that run locally, privately, and without a price tag.
I love building things that are useful. Tools that solve real problems, that don't require an account, and that respect your time.
I'm not a career developer. I'm a geography graduate who fell in love with the web, with learning, and with the joy of creating something that works.
This site started as a way to learn — to understand how browsers work, how APIs talk to each other, and how to make design feel simple and pleasant. Every tool here was a question I wanted to answer. Every line of code was a step forward.
I believe that good tools don't need to be complicated or expensive. They can be beautiful, intuitive, and free. That's what I'm trying to build, one tool at a time.
Privacy first
Your files never leave your browser. No uploads, no servers, no tracking.
Design with care
Simple, clean, and pleasant to use. I pay attention to the details.
Learning by building
Every tool is a question I wanted to answer. This site is my notebook.
Building this site has been an intense learning journey. I've spent countless nights figuring out how to make PDFs work in the browser, how to process images locally, and how to make interfaces feel simple and warm.
I'm a geographer by training, but I've always been curious about how things work. This is my way of exploring — by creating something useful, sharing it with the world, and learning along the way.

No signup. No file uploads. Just tools that work.
