Mistral Vibe is Mistral AI’s open-source command-line coding assistant. It gives developers a conversational interface to their codebase, powered by Mistral’s models, so they can explore, modify and interact with projects using natural language from the terminal. The repository is maintained by Mistral AI on GitHub, has collected more than 5,100 stars, and was actively updated in 2026.
Vibe runs locally as a Python application and works directly inside your project directory. You describe what you want in plain language and the assistant uses its built-in tools to inspect files, make changes and answer questions about the code. It targets UNIX environments first, with Windows also supported, and installs in one line through the official installer script or with the uv package manager. Configuration covers API keys, custom system prompts, custom agent configurations, tool management and MCP server connections, so teams can adapt the assistant to their own workflow and standards.
Mistral Vibe is free and open source under the Apache-2.0 license. You connect it with your own Mistral API key, so model usage itself is billed separately by Mistral according to the models you use.
Vibe is for developers who prefer terminal-first workflows and want a capable coding agent without leaving the command line. It is a natural fit for Mistral model users, Python developers, and teams that want an open, hackable assistant they can configure with their own prompts, tools and MCP servers.
