Choose goose if you want a free, open source agent that runs on your machine and works with whichever model provider you already pay for. Choose Claude Code if you want Anthropic's own coding agent in one subscription, from Pro at $20 monthly, as of October 2026. goose can even use Claude Code as a provider.
This comparison isn't quite a rivalry. goose is an open source agent with no price on its own pages, and the bill comes from whichever model it talks to. Claude Code is Anthropic's paid coding agent. I read goose's project home page and Anthropic's Claude plans page plus its Claude Code setup and costs docs, and everything here comes from those pages, as of October 2026.

What goose is
goose describes itself as a general-purpose AI agent that runs on your machine. It isn't only for code: its page lists research, writing, automation and data analysis too. It comes as a desktop app, a CLI and an API, and it's open source under the Apache 2.0 licence.
It works with 15+ providers, including Anthropic, OpenAI, Google, Ollama, OpenRouter, Azure and Bedrock. You can use API keys, or your existing Claude, ChatGPT or Gemini subscription via ACP. goose also works as an ACP server, so you can connect to it from Zed, JetBrains or VS Code, and it can use ACP agents like Claude Code and Codex as providers.
It connects to 70+ extensions, such as databases, APIs, browsers, GitHub and Google Drive, through the Model Context Protocol open standard, and it can spawn independent subagents to run tasks in parallel. The project is part of the Agentic AI Foundation at the Linux Foundation, which it says keeps it vendor-neutral and community-governed.
What Claude Code costs to run
Claude Code is Anthropic's agentic coding tool for the terminal, IDE, desktop app and web. Its setup docs say it needs a Pro, Max, Ultra, Team, Enterprise or Console account, and the free Claude plan doesn't include it.
Pro is $17 a month with the annual discount ($200 billed up front) or $20 monthly. Max is $100 a month and Ultra is $200 a month. Limits run every 5 hours, at 1x on Pro and 5x on Max, and Ultra has no 5-hour limit. Team seats start at $20 a seat a month billed annually. Through a Console account, Claude Code charges by API token use, and Anthropic's costs doc puts the enterprise average at around $13 per developer per active day.
Why the free one still has a bill
goose costs nothing to download, but an agent with no model behind it doesn't do anything. You either bring API keys and pay per use, or plug in a Claude, ChatGPT or Gemini subscription you already have. So the real question isn't goose or Claude Code. It's whether you want Anthropic's agent itself, in one subscription, or a vendor-neutral agent that sits on top of whichever model you already pay for, and that can even call Claude Code when you want it.
Which setup suits you
- One subscription and Anthropic's own coding agent: Claude Code, from Pro.
- You already pay for ChatGPT or Gemini and don't want another plan: goose, connected via ACP.
- You want to switch between models or run local ones through Ollama: goose.
- You want an agent for research, writing and automation as well as code: goose.
- You pay for Claude and like goose's extensions: run goose with Claude Code as its provider.

If you're shortlisting, the names that come up next to these two are Codex, Cline, Cursor and Gemini CLI. Check which models each one can use, because that decides your bill.

My advice on goose and Claude Code
If you're a Claude subscriber who mainly writes code, I'd start with Claude Code, because it's already in your plan and needs no setup beyond logging in. If you like to choose your own models, or you already pay for something other than Claude, goose is worth installing, because it's open source and works with what you've got. And you don't have to choose for good: goose can use Claude Code as a provider.
If you're setting up AI agents for a team and want help getting them working day to day, this is what I do all day. I run AI training and workshops for teams, and help businesses with AI enablement and workflow automation, so the busywork runs itself and people get time back. Most of that work is with SaaS marketing teams and small businesses. Here's how we can work together.
