Instrumental.dev

Rails UI components to build your app the easy way.

Build better products, faster. Common UI components and templates to get you started. Easy to customize as you build.

For builders who love this stack:

When I build with components, I want to do 3 things:

Keep it simple.
Make it mine.
Ship it fast.

Instrumental.dev is my collection of components that my team and I use to build and ship products, fast.

No magic. No bloat. Just quality components for your Rails projects (and ours). Let's make building with components easy, fun and productive. Just like Rails, itself.
