To build apps for the people who use them.
A world where getting help never costs you.
New apps are in the works, made with the same care. Each will be listed here once they are released.
How we work
Empty Cup Development LLC is run by one person, working with a set of Claude projects that each act as one department of a company. The guide explains how, step by step, and offers a free kit that sets up Claude to walk you through building your own.
Read the guideWe plan first, then shape each tool around the job it does, in terms anyone can work with.
We build step by step, from R&D to onboarding, then product design and project management, and finally software engineering.
We take pride in our work, look to fix what isn't working, add what is needed, and make things right.
How we build
We write our code with help from AI coding tools, including Claude Code. AI tools also help review each change, and we are putting automated checks in place for every tool. A change goes live only after its checks pass.

Ask as little as possible.No accounts necessary.
Keep nothing.We hold the least we can about you, and say exactly what that is.
Free and frugal.Every tool we make costs nothing to use, and we run on free plans wherever we can.
Say it plainly.What a tool can't do sits next to what it can, in words anyone can read.
Careful by default.Small steps, and tests before anything changes.
Beginner's mind.We check what we think we know, and listen before we build.
Built to last.Plain, well-supported tools, kept simple enough to look after for years.
A sustainable pace.We work at a pace we can keep, and finish what we start.
We read what you send. We can't always reply quickly. We appreciate your patience.
