Open-source terminal AI coding agent by Google, Apache 2.0 licensed. Since 2026-06-18, Login with Google no longer works for personal accounts, according to Google's Gemini Code Assist deprecation notice; the README still advertises 60 requests a minute and 1,000 a day with a personal Google account. With a Gemini API key, use counts against the Gemini API's own free tier and pricing. A Gemini Code Assist Standard or Enterprise licence is unaffected. Supports MCP tools, shell commands and file editing. Best for personal projects. Note — 2026-06-18: Gemini CLI stopped accepting Login with Google for personal accounts on 2026-06-18, which ended the personal-account free tier of 60 requests a minute and 1,000 a day. It still runs with a Gemini API key, Vertex AI, or a Gemini Code Assist Standard or Enterprise licence. Source ↗

Coding agent by OpenAI. Available with a ChatGPT subscription, including the $0 Free plan, and separately with an API key billed on token use; both routes are current. OpenAI's Codex pricing page lists Free ($0/month, "Explore Codex capabilities on quick coding tasks") and Go ($8/month, "Use Codex for lightweight coding tasks"), both with GPT-6 Luna at Standard speed in the desktop app, subject to rollout. Plus ($20/month) adds Codex on the web, in the CLI, in the IDE extension and on iOS, cloud code review and Slack integrations, and GPT-6 Sol. Pro (from $100/month) gives 5x or 20x more Codex usage than Plus. ChatGPT Business has two seat types, both carrying Codex: Standard at $20/user/mo billed annually ($25 monthly) and Premium at $100/user/mo billed annually ($125 monthly), where Premium buys 5x more usage than Standard and removes the five-hour usage limit. The Codex pricing page we cite lists only the Standard seat — the Premium seat is published on OpenAI's business pricing page. Codex-only pay-as-you-go seats closed to new Business workspaces on 2026-06-24; existing seats continue. With an API key, Codex runs in the CLI, SDK or IDE extension at API prices, without the cloud features.
