I built a Rust replacement for ccusage — 1,742x faster, near-zero overhead

TL;DR : I built Toki — a Rust daemon that replaces ccusage for Claude Code / Codex token tracking. ~1,742× faster on warm queries, near-zero overhead. Two optional layers sit on top: toki-monitor (macOS menu bar app) and toki-sync (self-hostable sync server). FSL-1.1-Apache-2.0, solo project. The problem: ccusage was making my laptop crawl I'm a Korean dev who burns a lot of tokens in Claude Code and Codex. At my workplace we'd been keeping a half-joking ccusage leaderboard of who was burning th
