Show HN: Track Token Usage from Codex CLI with Splitrail (OSS, Rust)

1 bl-ue 0 9/18/2025, 4:20:35 PM github.com ↗
I built Splitrail, an open source Rust TUI that turns Codex CLI, Claude Code, and Gemini CLI session logs into token usage and cost so you can measure real productivity (local first; optional free and OSS cloud and leaderboard integrations). I wanted vendor agnostic, fast, and local analytics across agentic tools. I also wanted to be able to easily track usage across multiple devices.

Codex CLI v0.32.0 added token fields to its JSONL “rollout” files (cached/input/output). Splitrail v1.1.0 supports the new event-based format today.
