Just days after OpenAI introduced third-party app integrations in ChatGPT, Google has unveiled Gemini CLI Extensions, a new system allowing developers and companies to integrate directly with its command-line AI tool, Gemini CLI. This marks a major expansion in Google’s developer ecosystem, enabling open participation without requiring Google’s approval.
Gemini CLI, launched in June 2025, already has over one million users mostly software developers. It serves as a coding assistant powered by Google’s Gemini AI, helping automate and enhance programming tasks directly from the command line.
Google has officially introduced Gemini CLI Extensions, a new feature allowing external developers and companies to integrate directly into its command-line AI tool, Gemini CLI. The launch aims to make the AI system more flexible and open for third-party innovation, with early partners including Figma and Stripe.
According to Taylor Mullen, senior staff engineer at Google, this open approach promotes a “fair ecosystem” accessible to all developers. The first available extension, Google’s Nanobanana image generator, allows users to generate AI images directly through the Gemini CLI terminal.
The move comes shortly after OpenAI launched its own third-party integration feature for ChatGPT, intensifying competition in the AI developer tools market. Ryan J. Salva, Google’s senior director of product management for developer tools, said the goal is to make Gemini CLI “an extensibility platform a bridge connecting multiple tools within developers’ workflows.”
