ccusage analyzes coding agent CLI token usage and costs from local data ^[1]. Gemini CLI gives lightweight access to Gemini models ^[2] and can query and edit large codebases ^[2]. AgentHydra shows Claude Code, Codex and OpenCode sessions in one searchable list, updated live ^[3], and shows cost at API list prices by day, model, project and account ^[3].

ccusage	Analyzes coding agent CLI token usage and costs from local data ^[1]; reads local usage data from coding agent CLIs and turns it into daily, weekly, monthly and session reports ^[1]; supports sources including Claude Code, Codex and OpenCode ^[1]; tracks and displays cache creation and cache read tokens separately ^[1]	not published	Runs without a global install through npm or other package runners ^[1] and through npx ^[1]; MIT License ^[1]

The short answer

ccusage analyzes coding agent CLI token usage and costs from local data ^[1], and it tracks and displays cache creation and cache read tokens separately ^[1]. Gemini CLI gives lightweight access to Gemini models ^[2], and it can query and edit large codebases ^[2]. AgentHydra shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run ^[3], and shows cost at API list prices by day, model, project and account ^[3].

Match the tool to the need. If the need is a report on what the coding agents on your machine have used, ccusage's page says it reads that from local data ^[1]. If the need is a Gemini agent working in the terminal, Gemini CLI's page says it provides lightweight access to Gemini models ^[2]. If the need is one list of running sessions across Claude Code, Codex and OpenCode, AgentHydra does that ^[3].

What ccusage, Gemini CLI is built for

ccusage analyzes coding agent CLI token usage and costs from local data ^[1]. Its page lists the sources it supports, including Claude Code, Codex, OpenCode, Amp, Droid, Codebuff, Hermes Agent, pi-agent, Goose, OpenClaw, Kilo, Kimi, Qwen, GitHub Copilot CLI, Gemini CLI, Antigravity, Grok Build CLI and ZCode ^[1]. It tracks and displays cache creation and cache read tokens separately ^[1]. Check its own page to confirm that your agent's records are among the ones it reads.

Gemini CLI gives lightweight access to Gemini models ^[2] and can query and edit large codebases ^[2]. Its page says new nightly releases are published each day at 00:00 UTC ^[2]. The facts given here do not say which Gemini models or plans it works with, so check its own page for that.

What AgentHydra is built for

AgentHydra is made by the team that publishes this site. It shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run ^[3]. It lists each Claude and Codex account with its plan and 5-hour and weekly quota, and can open, focus, quit, create and delete Claude Desktop instances ^[3]. It shows cost at API list prices by day, model, project and account ^[3], and prints the same cost numbers as JSON from the command line ^[3]. It exposes its features as MCP tools, including whoami and usage checks so an agent knows which account it is on and how much quota is left ^[3]. It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions ^[3]. It splits a task's pieces across Claude Code CLI sessions on your accounts, and moves a worker to another account when one nears its limit ^[3].

Pricing and fees

The facts given here do not state a price for ccusage, so its cost is not published here ^[1]. They do not state a price for Gemini CLI either, so its cost is not published here ^[2]. AgentHydra is free, with no account or subscription ^[3]. Nothing in the facts given here describes a card fee or a separate payment service for any of the three tools, so none is stated. If the cost of ccusage or Gemini CLI matters for your own use, check their own pages, since the facts here do not give a figure. The only price stated in the facts given here is free for AgentHydra ^[3].

Setting it up and daily use

AgentHydra's tray app needs Windows; macOS and Linux builds exist but have not been verified ^[3]. On Windows, install it with a one-line PowerShell script, or download a build from GitHub Releases or run from source with Bun ^[3]. Day to day, its session list stays updated live while sessions run ^[3], and cost figures are shown by day, model, project and account ^[3]. It is open source under the MIT License ^[3].

For ccusage, the facts given here say it reads local data ^[1] and list the sources it supports ^[1], and say nothing about installing it, so check its own page for that. For Gemini CLI, its page says nightly releases are published each day at 00:00 UTC ^[2], and the facts given here say nothing about installation, so its own page is the place to check.

Things to check before you choose

Ask which agents and accounts a tool reads from. ccusage's page says it analyzes token usage and costs from local data ^[1] and lists the sources it supports ^[1], so check that yours is among them. Ask whether the cost figures are list prices or the amounts you are billed: AgentHydra shows cost at API list prices ^[3]. Ask where the tool runs: AgentHydra's tray app needs Windows, and macOS and Linux builds exist but have not been verified ^[3]. Ask how often it changes: Gemini CLI publishes nightly releases each day at 00:00 UTC ^[2]. Ask whether cache tokens are counted apart from other tokens: ccusage tracks and displays cache creation and cache read tokens separately ^[1]. Check each tool's own licence terms before you build on it.

How to choose

Pick by the need, not by the name. If the need is reports on what the coding agents on your machine have used, ccusage's page says it analyzes token usage and costs from local data ^[1] and tracks cache creation and cache read tokens separately ^[1]. If the need is a Gemini agent in the terminal that can query and edit large codebases, that is what Gemini CLI's page says it does ^[2]. If the need is one live list of Claude Code, Codex and OpenCode sessions with cost at API list prices beside it, AgentHydra does that ^[3] ^[3]. A developer can use ccusage for local usage reports ^[1] and Gemini CLI for terminal work on codebases ^[2], and AgentHydra for the running sessions across accounts ^[3].
