Why we build

Built from real problems,
not feature checklists.

McCoy Software Tools LLC is an independent software company focused on practical applications that make specific tasks easier. The goal is simple: understand the workflow, remove the friction, and build the tool people actually wish they had.

01
Practical by design

Useful first. Clear second. Everything else earns its place.

02
Focused on the user

Designed around real workflows instead of forcing people into awkward ones.

03
Simple ownership

Tools should feel accessible, straightforward, and worth keeping around.
