# gemini-cli vs rea

gemini-cli and rea share 4 technologies: MCP, Zod, Ajv, and ajv-formats. Both are written in TypeScript.

- [google-gemini/gemini-cli](https://seerepo.com/r/google-gemini/gemini-cli): An open-source AI agent that brings the power of Gemini directly into your terminal.
- [morluto/rea](https://seerepo.com/r/morluto/rea): Reverse engineer anything with agents, from app behavior down to native binaries.

## What they share and what sets them apart

- In common: MCP, Zod, Ajv, ajv-formats
- Only in gemini-cli: Express, React, @agentclientprotocol/sdk, winston, ink, @xterm/headless, cli-spinners, prompts, lowlight, js-yaml, html-to-text, marked, zod-to-json-schema, OpenTelemetry
- Only in rea: @clack/prompts, xterm, cairosvg, @xmldom/xmldom, yaml, plist, parse5, saxes, har-schema, pino

| Who writes it | 8.2% of its commits signed by AI. With Gemini CLI, Jules, and GitHub Copilot | 16.3% of its commits signed by AI. With Claude Code, Codex, Cursor, Factory, GitHub Copilot, and Devin |
| Activity | Last push November 4, 2026, 6,573 commits, 108,723 stars | Last push November 4, 2026, 5,979 commits, 428,191 stars |
| Tests | 1,056 test files. 86.1% of its code files have a test that imports them | 3,518 test files. 66.6% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
