Cline and Gemini CLI are coding agents, and this page weighs them. Cline has a desktop app for macOS and Windows ^[1], supports several models ^[2], and its command line tool runs scripts, cron jobs and CI pipelines ^[2]. Gemini CLI installs globally with npm ^[3], with stable releases each week on Tuesdays at 20:00 UTC ^[3] and preview releases the same day at 23:59 UTC ^[3].

Option	What its sources say it does	Cost	Account or install
Cline	Autonomous coding agent ^[1]; desktop app for macOS and Windows ^[1]; CLI runs scripts, cron jobs and CI pipelines ^[2]	not published	Desktop app, IDE extension, CLI and SDK; no account stated in the facts
Gemini CLI	Open-source AI agent in the terminal ^[3]; stable releases weekly on Tuesdays at 20:00 UTC ^[3]	not published	Install globally with npm ^[3] or run with npx ^[3]
AgentHydra	Searchable list of live Claude Code, Codex and OpenCode sessions ^[4]; cost at API list prices ^[4]	free ^[4]	No account ^[4]; MIT License ^[4]; tray app needs Windows ^[4]

The short answer

Cline and Gemini CLI are coding agents, and people open this page to compare them for their own agent work. Cline has a desktop app for macOS and Windows ^[1], works with Claude, GPT, Gemini, local Ollama or LM Studio, and OpenAI-compatible endpoints ^[2], and its command line tool can run scripts, cron jobs and CI pipelines ^[2]. Gemini CLI is installed globally with npm ^[3], and its stable releases are published each week on Tuesdays at 20:00 UTC ^[3], with preview releases the same day at 23:59 UTC ^[3]. AgentHydra is made by the team that publishes this site and adds a living list of sessions and other housekeeping around coding agents. Pick by the work you need: where a tool's own pages say it does that work, it fits the need.

What Cline, Gemini CLI is built for

Cline is described as an autonomous coding agent that runs as an SDK, IDE extension, or CLI assistant ^[1], and its source says one agent works across the IDE, terminal and SDK ^[2]. It has a desktop app for macOS and Windows ^[1] and a CLI with a terminal UI, headless mode, shell commands and CLI-specific flows ^[1]. Its source says it supports Claude, GPT, Gemini, local Ollama or LM Studio, and OpenAI-compatible endpoints ^[2]. Its CLI can run scripts, cron jobs and CI pipelines ^[2]. It can make coordinated changes across large codebases ^[2], be extended with MCP and plugins ^[2], and is an open source agent runtime ^[2]. Gemini CLI is installed globally with npm ^[3], and its stable releases are published weekly on Tuesdays at 20:00 UTC ^[3], with preview releases at 23:59 UTC ^[3]. Its other capabilities, such as what it does in the terminal, are shown in the table below.

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 ^[4]. It lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions ^[4]. It moves a Claude chat, history included, to another of your accounts ^[4], and splits a task's pieces across Claude Code CLI sessions on your accounts, moving 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, and can open, focus, quit, create and delete Claude Desktop instances ^[4]. It exposes its features as MCP tools, including whoami and usage checks ^[4]. It packs a task and its repository into a Markdown file, leaving out common secret files, then copies a prompt and opens ChatGPT for you to send yourself ^[4].

Pricing and fees

The facts given here do not state a dollar price for Cline, so none is published here ^[1]. The facts also give no dollar price for Gemini CLI, so none is published here ^[3]. The only price given in the facts for any tool here is that AgentHydra is free, with no account and no subscription ^[4]. AgentHydra is open source under the MIT License ^[4]. If you need the cost of Cline or Gemini CLI for your own use, check their own pages, since the facts here do not state one.

Setting it up and daily use

Cline is available as a desktop app for macOS and Windows ^[1], and its CLI runs scripts, cron jobs and CI pipelines ^[2]. Gemini CLI is installed globally with npm ^[3]; its stable releases come weekly on Tuesdays at 20:00 UTC ^[3] and preview releases the same day at 23:59 UTC ^[3]. For AgentHydra, the tray app needs Windows, and macOS and Linux builds exist but have not been verified ^[4]. On Windows, install it with a one-line PowerShell script, download a build from GitHub Releases, or run it from source with Bun ^[4]. There is no account or subscription to set up, since AgentHydra is free ^[4]. Day to day, AgentHydra lists live sessions ^[4] and prints the same cost numbers as JSON from the command line ^[4]. The facts here say nothing more about setup or routine use for Cline or Gemini CLI, so check the tools' own pages for anything further.

Things to check before you choose

Ask which models you need. Cline's source says it supports Claude, GPT, Gemini, local Ollama or LM Studio, and OpenAI-compatible endpoints ^[2], while the facts here give no model list for Gemini CLI, so check its own pages. Ask where you want the tool to run. Cline has a desktop app for macOS and Windows ^[1], and Gemini CLI is installed with npm ^[3]. Ask whether you need scheduled runs. Cline's CLI runs scripts, cron jobs and CI pipelines ^[2]. Ask what data stays on your machine. AgentHydra lists sessions and quota on your machine ^[4] and is open source under the MIT License ^[4]. Ask whether a price is published. Neither Cline nor Gemini CLI has a stated dollar price in these facts, so check each tool's own pages ^[1] ^[3].

How to choose

Match the work to the tool whose own sources say it does that work. For an agent that runs across a desktop app, terminal and SDK and keeps code consistent across large codebases, Cline's pages describe that ^[2] ^[2], and its CLI runs scripts, cron jobs and CI pipelines ^[2]. Gemini CLI is installed globally with npm and ships stable releases weekly on Tuesdays ^[3] ^[3]. For tending the agents themselves, AgentHydra lists live sessions on your machine ^[4] and tracks cost at API list prices ^[4]. If you want a free, open source option with no account, AgentHydra is that ^[4] ^[4]. Where the facts are silent on a tool, check its own pages before choosing.
