What this domain is for.

01

Master domain

www.chopstickshq.com is the hub. Product sites live under /rnitro, /fathom, /fathom-pro, and more.

02

Own the stack

Projects stay lightweight: native apps, clear installers, and a website you can actually read.

03

Privacy-first

No accounts, no tracking pixels for product installs. rNitro, Fathom, and Fathom Pro do not phone home.
