Claude Code
from $20/moTerminal-based coding agent that runs commands and edits files directly.
Claude Code vs Gemini CLI
A decision-first comparison built around the workflow, constraint or switching cost that actually separates these products.
Gemini CLI
Free tier availableGoogle's open-source terminal agent, with the most usable free tier of the group.
So which one
Both are terminal agents from the company that trained the model, so the difference is what you pay with. Claude Code comes with a Claude plan: no separate line item, prompts tuned by the people who built the model, and the shortest path to good output if you already subscribe. Gemini CLI comes with a free tier big enough to do real work, which makes it the cheapest way to find out whether this category suits you before committing to anyone. Pick Claude Code if you are already paying Anthropic — you are buying the model, and the tool is how it reaches you. Pick Gemini CLI if you are still deciding, or if a second opinion from a different model is worth more to you than a tuned one.

Choose by workflow
Choose Claude Code if
- Multi-step changes where the steps depend on what is found along the way
- Work already centred on the terminal and git
- Tasks where running the tests is the natural way to check the result
An agent that works in the terminal rather than an editor, which suits people whose workflow is already command-line shaped. It reads the repository, makes changes across files and runs the tests, and the honest advantage over completion tools is that it closes the loop — it can check whether what it wrote actually works. The honest disadvantage is the same as every agent: it will occasionally report success on work that needs another look.
Choose Gemini CLI if
- Trying a terminal agent without committing to a subscription
- A second opinion when another agent gets stuck
- Repository-wide reading tasks that benefit from a large context window
The cheapest way to find out whether a terminal agent fits how you work, because the free tier is large enough for real tasks rather than a demo. Treat that as its main role: an evaluation path and a second opinion, rather than the tool you standardise a team on. Free quotas at this size have historically been the first thing to change, so do not build a workflow that breaks when it does.
When to skip each one
Skip Claude Code if
- Tasks with fixed steps you could write as a script
- Anyone uncomfortable granting a tool write access to a repository
- Work where a wrong action is expensive to undo
Skip Gemini CLI if
- Workflows that must keep working regardless of quota policy changes
- Teams that have standardised on another model vendor
- Anyone who needs to route the same task across several providers
Known limitations
Claude Code
- Cost scales with steps taken, not with questions asked
- Requires meaningful permissions over your files and shell
- Verifying the result is your job, and it is where the time goes
Gemini CLI
- Free quotas and their terms have changed before and can change again
- Tied to Google models
- Smaller third-party ecosystem than the model-agnostic options
