Overview總覽

Obolus reads the session history that Claude Code and OpenAI Codex already write locally, and attributes AI development spend to each repo, branch, commit, and session. It touches metadata only; code and prompts never leave the machine. No API key, no telemetry.

Obolus 讀取 Claude Code 與 OpenAI Codex 在本機既有的 session 紀錄,將 AI 開發花費歸因到每個 repo、分支、commit 與工作階段。僅處理 metadata,程式碼與 prompt 不離開本機;無需 API key,無遙測。

Key Capabilities核心能力

  • Spend attributionCost by repo, branch, commit, day, and session, across both vendors
  • Three interfacesA macOS menu-bar app, a web dashboard (npx obolus serve), and a one-shot terminal report (npx obolus scan)
  • TrendsToday against your daily average; a 7-day trend stacked by vendor
  • Codex quotaOne tap switches between dollars and the 5-hour rolling quota
  • Zero setupIt reads the history your agents already keep; install and run
  • 成本歸因花費按 repo、分支、commit、日期、session 拆解,跨雙供應商(Claude Code、Codex)
  • 三種介面macOS 選單列 app、web dashboard(npx obolus serve)、終端機單次報告(npx obolus scan)
  • 趨勢視圖今日與每日平均對照、7 日趨勢按供應商堆疊
  • Codex 配額切換$ 與 5 小時滾動配額一鍵切換
  • 零設定讀取 agent 既有的本機紀錄,安裝即用
