## Side by side

### Google Gemini CLI

- What it is: Google's open-source (Apache-2.0) coding agent for the terminal: it reads and edits your codebase, runs shell commands, connects MCP servers and runs headless with gemini -p for scripts. Now built for Gemini Code Assist Standard and Enterprise teams and paid Gemini API or Vertex AI keys; free and Google AI Pro/Ultra users moved to Antigravity CLI.
- Category: AI Editors & Agents (https://digidle.com/category/ai-editors/)
- Tags: cli, agent, open-source
- Where It Runs: Terminal on macOS, Windows and Linux. VS Code companion extension, plus JetBrains and Zed through ACP. Preinstalled in Google Cloud Shell.
- Sign-In and Models: Sign in with Google on a Gemini Code Assist Standard or Enterprise license, or use a paid Gemini API or Vertex AI key.
- Scripting and CI: gemini -p runs headless, with JSON or streaming JSON output for scripts.
- Free Option: None anymore. Free and Google AI Pro/Ultra access moved to Google's Antigravity CLI on June 18, 2026.
- Pricing: Comes with Gemini Code Assist: Standard $19 per user a month on a 12-month term, $22.80 monthly, with 1,500 CLI and agent requests a day. Enterprise is $45 on a 12-month term, $54 monthly, with 2,000. Or a paid API key at API rates.

### OpenAI Codex CLI

- What it is: OpenAI's open-source (Apache-2.0) coding agent that runs locally in your terminal: it reads your repo, edits files and runs commands, with codex exec for scripts and CI. Sign in with ChatGPT or use an API key.
- Category: AI Editors & Agents (https://digidle.com/category/ai-editors/)
- Tags: cli, agent, open-source
- Where It Runs: Terminal on macOS, Linux and Windows. The same plan covers the Codex IDE extension, desktop app and Codex cloud.
- Sign-In and Models: Sign in with ChatGPT, or use an API key, where model access follows your key.
- Scripting and CI: codex exec runs non-interactive tasks in scripts and pipelines. API-key use suits CI but skips cloud features like GitHub code review.
- Free Option: The CLI is free to install. Using it starts with ChatGPT Plus, or an API key billed at API rates.
- Pricing: Included with ChatGPT Plus at $20/mo: CLI, IDE extension, web and iOS. Pro is $100, $200 or $500 a month. Business is $25 per user a month billed monthly. Or bring an API key and pay API rates.
