A small home studio. Tools built from curiosity and personal need, shared freely where possible — and priced fairly when real infrastructure demands it.
Explore our workSprytna is a small home studio dedicated to building software that solves problems with privacy-first focus. Named after the Polish word for clever, each product starts as something we wanted to use — built with love and shipped with intention.
Like the Masked Weaver bird — known for its iterative approach to crafting intricate, precisely built nests — we believe in building thoughtfully designed applications, one iteration at a time, always with a clear purpose. We prioritize privacy-first products with no ads as a core feature, not an afterthought. Most of our tools are free, while those that require real infrastructure are priced simply and fairly.
