Compare Codex CLI with AgentHydra, OpenCode, Claude Squad, Goose and Cline: what each does, its platform, and what to check before you choose.

Codex CLI lets you inspect code, make changes, run commands and automate repeatable work without leaving the terminal. [^1] If you want to see Claude Code, Codex and OpenCode sessions in one list, AgentHydra shows them together. [^2] The other options below are compared on what they do, their price and platform, and what to check before you pick one.

| Option | What it does | Price | Platform |
|---|---|---|---|
| Codex CLI | Lets you inspect code, make changes, run commands and automate repeatable work without leaving the terminal. [^1] | Not published | Standalone installer for macOS and Linux. [^1] |
| AgentHydra | Shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run. [^2] | Free, with no account or subscription. [^2] | Tray app needs Windows; macOS and Linux builds exist but have not been verified. [^2] |
| OpenCode | Can use any LLM provider by configuring API keys. [^3] | Not published | Terminal interface, desktop app and IDE extension. [^4] |
| Claude Squad | Manages multiple AI agents in separate workspaces. [^5] | Not published | Terminal app, installable with Homebrew. [^5] [^5] |
| Goose | Open source AI agent that can install, execute, edit and test with any LLM. [^6] | Not published | Desktop app for macOS, Linux and Windows. [^7] |
| Cline | Autonomous coding agent available as an SDK, IDE extension or CLI assistant. [^8] | Not published | Desktop app, CLI, IDE extension and SDK. [^9] |

## Why developers look past Codex CLI

Codex CLI lets you inspect code, make changes, run commands and automate repeatable work without leaving the terminal. [^1] It can be used interactively or called with codex exec from repeatable workflows and pipelines. [^1] Its resume command reopens a recent chat from the current repository, or searches across local chats for older work. [^1]

Developers who look at alternatives usually have a specific need in mind. Some run Claude Code or OpenCode next to Codex and want to see all of their sessions in one place. Others want to run several agents on one project at the same time, or see what their usage costs. The Codex CLI facts gathered for this page do not cover cost tracking or running several agents at once, so check those needs directly against the options below.

## AgentHydra: one list of sessions across tools and accounts

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. [^2] It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions. [^2] It moves a Claude chat, history included, to another of your accounts. [^2] 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. [^2]

It shows cost at API list prices by day, model, project and account. [^2] 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. [^2] 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. [^2] 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. [^2] It prints the same cost numbers as JSON from the command line. [^2]

It is free, with no account or subscription. [^2] It is open source under the MIT License. [^2] The tray app needs Windows; macOS and Linux builds exist but have not been verified. [^2] 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. [^2]

## OpenCode: works with any LLM provider you set up

OpenCode can use any LLM provider by configuring API keys. [^3] It can analyze a project and create an AGENTS.md file in the project root. [^3] It says it does not store any of your code or context data. [^4]

## Claude Squad: a terminal app that runs several AI agents in separate workspaces

Claude Squad is a terminal app that manages multiple AI agents in separate workspaces. [^5] The agents it names include Claude Code, Codex, Gemini, and other local agents, including Aider. [^5] Its configuration is stored in ~/.claude-squad/config.json. [^5] It can be installed with Homebrew. [^5]

## Goose: an open source, extensible AI agent

Goose is an open source, extensible AI agent that can install, execute, edit and test with any LLM. [^6] It can spawn independent subagents to handle tasks in parallel, for example code review, research or file processing. [^7] It includes prompt injection detection, tool permission controls, sandbox mode and an adversary reviewer that watches for unsafe actions. [^7]

## Cline: an autonomous coding agent available as an SDK, IDE extension or CLI

Cline is described as an autonomous coding agent, available as an SDK, IDE extension or CLI assistant. [^8] It supports extensions through MCP and plugins. [^9] It can answer questions about files, dependencies and behavior in a codebase. [^9]

## How to pick the right Codex CLI alternative

Choose AgentHydra if the main problem is keeping track of several tools and accounts. It shows Claude Code, Codex and OpenCode sessions in one searchable list. [^2] It also shows cost at API list prices by day, model, project and account. [^2]

Keep Codex CLI in view if you want to stay with the tool you already use. Its resume command reopens a recent chat from the current repository, or searches local chats for older work. [^1] It can be installed with a standalone installer for macOS and Linux. [^1]

Pick OpenCode if you want to bring your own model provider. It can use any LLM provider by configuring API keys. [^3] It says it does not store your code or context data. [^4] If you want several agents running in separate workspaces, look at Claude Squad, which manages multiple AI agents in separate workspaces. [^5]

Goose can spawn independent subagents to handle tasks in parallel. [^7] Check it if parallel subtasks are the main need. Cline can answer questions about files, dependencies and behavior in a codebase. [^9] Check it if the main need is asking questions about a codebase.

Before you choose, check which platform you use, since the tray app needs Windows. [^2] Check each tool's price on its own site too.
