Codex CLI is the OpenAI command-line tool that, by its own pages, lets a developer inspect code, make changes, run commands, and automate repeatable work without leaving the terminal, and it can switch a run to live web search or take an image with the first prompt. opcode (formerly Claudia) is, by its own page, a GUI app and toolkit for Claude Code ^[1] that needs Windows 10/11, macOS 11+, or Linux (Ubuntu 20.04+) ^[1]. The question of where you want to work picks between them: Codex CLI is built for work from the terminal, and opcode is built for a graphical app.

Option	What its sources say it does	Cost	Account or install
Codex CLI	Lets you inspect code, make changes, run commands and automate repeatable work without leaving the terminal ^[2]; codex --search switches a run to live web search when a task depends on current releases, documentation or external behavior ^[2]; codex --image passes an error screenshot, architecture diagram or design reference with the first prompt, or pastes an image into the interactive composer ^[2]	not published	Sign in with ChatGPT or another available sign-in method on first run ^[2]; standalone installer for macOS and Linux ^[2]
opcode (formerly Claudia)	A GUI app and toolkit for Claude Code ^[1]; create custom agents, manage interactive Claude Code sessions and run secure background agents ^[1]	not published	Windows 10/11, macOS 11+, or Linux (Ubuntu 20.04+) ^[1]; at least 1GB of free storage and a minimum of 4GB of RAM, 8GB recommended ^[1] ^[1]; data stays on the machine, with no data collection or tracking ^[1] ^[1]
AgentHydra	Shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live ^[3]; replies in a Claude session's desktop chat or to several sessions ^[3]; moves a Claude chat between your accounts ^[3]; splits a task across Claude Code CLI sessions and moves a worker when one nears its limit ^[3]; shows cost at API list prices by day, model, project and account ^[3]; pairs each failed shell command with the fix and can copy pairs out as a rules file ^[3]; lists each Claude and Codex account with plan and quota and manages Claude Desktop instances ^[3]	free, no account or subscription ^[3]; open source under the MIT License ^[3]	Windows tray app; macOS and Linux builds exist but have not been verified ^[3]; on Windows, install with a one-line PowerShell script, download a build from GitHub Releases, or run from source with Bun ^[3]

The short answer

Codex CLI is the command-line tool whose own pages say it lets you inspect code, make changes, run commands, and automate repeatable work without leaving the terminal ^[2]. Its pages also say codex --search switches a run to live web search when a task depends on current releases, documentation, or external behavior ^[2], and codex --image passes an error screenshot, architecture diagram, or design reference with the first prompt, or pastes an image into the interactive composer ^[2]. opcode (formerly Claudia) is, by its own page, a GUI app and toolkit for Claude Code ^[1]. Its page says it needs Windows 10/11, macOS 11+, or Linux (Ubuntu 20.04+) ^[1]. Which need each one meets: working from a terminal points to Codex CLI, and working in a graphical app for Claude Code points to opcode. Neither tool's facts give a price, so that side is not published here.

What Codex CLI, opcode (formerly Claudia) is built for

Codex CLI is the tool whose own pages describe working from the command line. Its pages say codex --search switches a run to live web search when a task depends on current releases, documentation, or external behavior ^[2], which helps when a change hinges on what is current rather than what a model already knows. Its pages say codex --image passes an error screenshot, architecture diagram, or design reference with the first prompt, or pastes an image into the interactive composer ^[2], which helps when a task needs something visual. Its pages say you can inspect code, make changes, run commands, and automate repeatable work without leaving the terminal ^[2]. opcode (formerly Claudia) is, by its own page, a GUI app and toolkit for Claude Code ^[1]. Its page says it needs Windows 10/11, macOS 11+, or Linux (Ubuntu 20.04+) ^[1], and that it is not affiliated with, endorsed by, or sponsored by Anthropic ^[1].

What AgentHydra is built for

AgentHydra is made by the team that publishes this site. AgentHydra shows the Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run ^[3]. It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions ^[3]. It moves a Claude chat, history included, to another of your accounts ^[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]. It shows cost at API list prices by day, model, project and account ^[3]. 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 ^[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].

Pricing and fees

The facts given here do not state a price for Codex CLI, so none is published here ^[2]. The facts given here do not state a price for opcode (formerly Claudia), so none is published here ^[1]. AgentHydra is free, with no account or subscription ^[3], and it is open source under the MIT License ^[3]. No source here describes a trial, a discount, or a fee charged on top of another service's fee, so none is stated. If you need the cost of Codex CLI or opcode for your own use, check their own pages, since the facts here do not give one.

Setting it up and daily use

The facts here say how opcode runs but nothing about how you install it, so check its own pages for that. opcode needs Windows 10/11, macOS 11+, or Linux (Ubuntu 20.04+) ^[1]. The facts here say nothing about installing or setting up Codex CLI itself, so check its own pages for that too. Codex CLI's own pages describe day-to-day use: codex --search switches a run to live web search when a task depends on current releases, documentation, or external behavior ^[2], and codex --image passes an image with the first prompt or pastes one into the interactive composer ^[2]. Neither Codex CLI nor opcode is described here with an account or a fee to set up, and the facts are silent on anything further, so check the tools' own pages for it.

Things to check before you choose

Ask where you want to do the work. Codex CLI is built for the terminal ^[2], and opcode is a GUI app for Claude Code ^[1]. Ask which system you run. opcode's page names Windows 10/11, macOS 11+, and Linux (Ubuntu 20.04+) ^[1], and the facts here say nothing about the systems Codex CLI supports, so check its own pages. Ask whether a task depends on the current web. Codex CLI can switch a run to live web search ^[2], and the facts here say nothing about that in opcode, so check. Ask whether you want session lists and account quota in one place; that is what AgentHydra's claims describe. Ask what each costs; the facts give a price for none of the three except the product, which is free ^[3].

How to choose

A developer who wants to stay in the terminal and pass current web context or an image gets that from Codex CLI, whose pages describe live web search ^[2] and images with the first prompt ^[2]. A developer who wants a graphical app for Claude Code on a named desktop system gets that from opcode, whose page describes a GUI app and toolkit ^[1]. A developer who wants one place to see running sessions, reply to them, move chats between accounts, track cost and spot repeated mistakes gets that from AgentHydra, whose claims describe those features ^[3] ^[3] ^[3]. The tools answer different questions, so pick by the question you have.
