About

refcard.dev is an independent reference site for AI coding tools — starting with Claude Code. It exists because official docs are slow to navigate, GitHub cheat sheets go stale, and Medium articles are outdated before they're indexed.

Every page is built from YAML source files that are auto-synced weekly from official changelogs. The goal is to be the fastest, most accurate place to look up a command, flag, or shortcut when you're in the middle of a session.

It's made by Theodor Nielsen — a developer based in Sweden.
