Indie apps and developer tools by Kai Yang.
I build tools for developers. Chrome extensions that fix workflow gaps, CLI apps that make terminal life better, and open source Python packages that solve real infrastructure problems.
The name “Visionary Future” is a reminder: build the tools you wish already existed. Everything here started as a personal need and grew into something others find useful.
Every app here solves a problem I actually had. No todo-list demos, no tutorial projects. Real code, real users.
Minimal dependencies. Fast builds. No tracking, no ads, no dark patterns. If a tool doesn't need a backend, it doesn't get one.
Source available unless there's a reason not to. Privacy policies written in plain English, not legalese.
