# Plandex AI Coding Agent for Large Projects
Plandex is an open-source terminal-based AI coding agent designed for large projects and complex tasks. It handles up to 2M tokens of context, uses a diff sandbox for safe changes, and supports multi-model workflows across Anthropic, OpenAI, and Google providers.
## Installation
Requirements and caveats from upstream:
- | **Self-hosted/Local Mode** | • Run Plandex locally with Docker or host on your own server.<br/>• Use your own [OpenRouter.ai](https://openrouter.ai) key (or [other model provider](https://docs.plandex.ai/models/mode...
- For a new project, you might also want to initialize a git repo. Plandex doesn't require that your project is in a git repo, but it does integrate well with git if you use it.
Basic usage or getting-started notes:
- 🧑💻 **REPL mode** with fuzzy auto-complete for commands and file loading. Just run plandex in any project to get started.
