| API | Yes, with an API key from Mistral Studio | Yes, through the OpenAI API |
| Where it runs | A terminal-native CLI, native extensions for Visual Studio Code, JetBrains and Zed, and the Vibe web app; installed with a single CLI command or with uv tool install mistral-vibe | Codex CLI in the terminal, an IDE extension, a desktop app, a cloud sandbox and automated pull request review, plus web and iOS |
| Inline completions | Yes, Tab to complete, with multi-line suggestions tailored to the codebase | No, Codex is an agent rather than an inline autocomplete |
