Codex CLI and Goose compared on what each does in a terminal, what each costs and what to check before you choose one.

Codex CLI is a terminal tool you install on macOS or Linux, and Goose is a general-purpose AI agent that runs on a machine ^[1] ^[2]. Codex CLI can be used interactively or called from repeatable workflows and pipelines ^[1], and it can reopen a recent chat from the current repository or search across local chats for older work ^[1]. Goose works with more than 15 providers, including Anthropic, OpenAI and Google ^[3], and it connects to over 70 extensions through the Model Context Protocol ^[3]. AgentHydra is a third option that gathers the sessions of several terminal agents into one live list. Pick by the kind of work you do: a terminal agent that returns to older chats points to Codex CLI, a machine agent tied to many providers and extensions points to Goose, and a single view across several agents' sessions points to AgentHydra.

Option	What its sources say it does	Cost	Account or install
Codex CLI	Inspect code, make changes, run commands and automate repeatable work without leaving the terminal ^[1]; switch a run to live web search with codex --search ^[1]; pass an image with codex --image ^[1]; sign in with ChatGPT on first run ^[1]; offers commands for model, permissions, status, review, init and resume ^[1] ^[1] ^[1] ^[1] ^[1] ^[1]	not published	installed with the standalone installer for macOS and Linux ^[1]
Goose	A general-purpose AI agent that runs on a machine ^[2]; works with 15+ providers such as Anthropic and OpenAI ^[3]; connects to 70+ extensions through the Model Context Protocol ^[3]; spawns independent subagents to handle tasks in parallel ^[3]; includes prompt injection detection and tool permission controls ^[3]	not published	a native desktop app, a CLI and an API ^[3]
AgentHydra	Shows Claude Code, Codex and OpenCode sessions in one searchable live list ^[4]; types a reply into a Claude session's own chat or to several sessions ^[4]; moves a Claude chat to another account ^[4]; splits a task across Claude Code CLI sessions and moves workers between accounts ^[4]; shows cost at API list prices ^[4]; pairs failed shell commands with the fixing command ^[4]; lists accounts with plan and quota ^[4]	free, with no account or subscription ^[4]	the tray app needs Windows; macOS and Linux builds exist but are not verified ^[4]

The short answer

What Codex CLI, Goose is built for

Codex CLI is installed with the standalone installer for macOS and Linux ^[1]. It can be used interactively or called with codex exec from repeatable workflows and pipelines ^[1]. With codex resume you can reopen a recent chat from the current repository, or search across local chats when you need to return to older work ^[1]. Goose is a general-purpose AI agent that runs on a machine ^[2]. It works with more than 15 providers, including Anthropic, OpenAI, Google, Ollama and OpenRouter ^[3]. It connects to over 70 extensions, such as databases, APIs, browsers, GitHub and Google Drive, through the Model Context Protocol ^[3]. The two terminal agents are compared here alongside the product below, because a developer may want one or both and a way to watch their sessions.

What AgentHydra is built for

AgentHydra is made by the team that publishes this site. AgentHydra shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run ^[4]. It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions ^[4]. It can move a Claude chat, history included, to another of your accounts ^[4]. 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 ^[4]. It shows cost at API list prices by day, model, project and account ^[4]. It pairs each failed shell command with the command that fixed it, and can copy those pairs out as a rules file for your agents ^[4]. It lists each Claude and Codex account with its plan and 5-hour and weekly quota ^[4].

Pricing and fees

AgentHydra is free, with no account or subscription ^[4]. The facts given here do not state a dollar price for Codex CLI or Goose, so their prices are not published here ^[1] ^[2]. Neither source describes any account, trial or discount for either tool, so none is stated here. The only price given in the facts is free for AgentHydra ^[4]. The cost figures AgentHydra shows are at API list prices ^[4], not the amount actually billed. If you need the cost of Codex CLI or Goose for your own use, check their own pages, since the facts here do not state one.

Setting it up and daily use

Codex CLI is installed with the standalone installer for macOS and Linux ^[1]. On the project, you can use it interactively or call codex exec from repeatable workflows and pipelines ^[1]. With codex resume you reopen a recent chat from the current repository, or search across local chats when you need to return to older work ^[1]. Goose is a general-purpose AI agent that runs on a machine ^[2]. You pick which of its providers each task runs with, and its extensions connect through the Model Context Protocol ^[3] ^[3]. AgentHydra needs Windows for its tray app; macOS and Linux builds exist but have not been verified ^[4]. On Windows, you install it with a one-line PowerShell script, or download a build from GitHub Releases, or run it from source with Bun ^[4]. Once it is running, you see Codex and OpenCode sessions in one live list ^[4]. It can print the same cost numbers as JSON from the command line ^[4]. Its features are also exposed as MCP tools, so an agent can check which account it is on and how much quota is left ^[4].

Things to check before you choose

Ask what the tool needs to run on. Codex CLI is installed for macOS and Linux ^[1], Goose runs on a machine ^[2], and AgentHydra's tray app needs Windows, with macOS and Linux builds not yet verified ^[4]. Ask whether returning to older work matters: Codex CLI's resume searches local chats ^[1], while the facts here say nothing about that in Goose, so check Goose's own pages. Ask whether you work with several providers and extensions: Goose connects to 15+ providers and 70+ extensions ^[3] ^[3], while the facts here say nothing about that for Codex CLI, so check its pages. Ask what you want to watch while agents run: AgentHydra shows sessions from Codex and others in one live list ^[4]. Ask whether a price is stated, since the facts give none for Codex CLI or Goose.

How to choose

Match the tool to the work you do. If you want a terminal agent installed on macOS or Linux that you call from repeatable workflows, Codex CLI is built for that ^[1] ^[1]. If you want to return to earlier chat work from the current repository, Codex CLI's resume does that ^[1]. If you want a machine agent that works with many providers and extensions, Goose is built for that ^[3] ^[3] ^[2]. If you want one live list of the sessions your terminal agents are running, or to watch account quota and cost, AgentHydra is built for that ^[4] ^[4] ^[4]. Try the tool whose source matches the need you have now, and add the others if you want its different view.
