Apps that leave you happier.
Tools that get out of the way.
FoldableStack is an independent product company. We make small, carefully built software for people and for the developers who ship it.
We run two lines. Foldable Apps is where the consumer products live: a game recommender, a daily ritual for families, a clean-air finder, and a space tycoon still in the oven. Foldable Tools is where we build for developers, from an open-source command runner to an agent that keeps your end-to-end tests green. Different products, one standard: useful, understandable, and carefully made.
Two product lines
Foldable Apps
Delightful consumer products
Small apps with a point of view. Each one does a single thing well, looks good doing it, and respects your time. Some are live today, some are still in the works.
Foldable Tools
Developer tools that get out of the way
Opinionated tools for people who ship. Deadpool Runner is open source and built in public. Pass Line is a paid service that keeps your critical user flows green.
Details are not details.
They make the product.
Ship fast, ship right
Speed and quality are not a tradeoff. We move fast because we know exactly what matters. Every interaction is intentional. Every feature earns its place.
Simple is hard
Anyone can add complexity. The real work is removing it. We obsess over making products that feel obvious, the kind of simple that only comes from deeply understanding the problem.
Joy as a metric
If using our product does not make you feel something good, we have not done our job. We sweat the font weights, the animation curves, the way a button feels under your thumb. Delight lives in the details.
Ownership over layers
We keep decisions close to the work. The people shaping each product stay involved through implementation, testing, and release.
