Kalfa Labs
Sign in
Small, sturdy utility apps.
Kalfa Labs is a one-person studio in Turkey building focused web apps for personal finance and everyday tracking. Each app does one job, runs on its own address, and installs to the phone home screen.
A kalfa is the journeyman of the Turkish workshop tradition: past apprentice, still learning the trade by building.

Built with Claude
Every Kalfa Labs app is designed, built and maintained with Claude Code, on Cloudflare Pages and Supabase.
Next on the list are Claude-powered features inside the apps: automatic categorization of spending and payment records, and a personal assistant that answers questions over notes, trip plans and travel documents.
