Plandex is a terminal-based open source AI coding agent built for large tasks and real-world projects. It can plan and execute multi-step changes across dozens of files, with up to 2M tokens of effective context and tree-sitter project maps for indexing larger codebases. A cumulative diff review sandbox keeps AI-generated changes separate from your files until you're ready to apply them. It suits developers working on sizable projects where other AI tools struggle with scale or complexity.
