Overview
Plandex is a terminal-first AI agent designed to plan and execute multi-step changes across large codebases. It supports project maps, context caching, syntax and logic validation, and a diff-review sandbox to make AI-driven edits safer and production-ready.
Key Features
- Massive context management: supports project maps and effective context windows suitable for large repositories.
- Configurable autonomy: run in fully autonomous or review-driven modes, with branching plans and versioned edits.
- Production-ready tooling: built-in syntax checking, automated debugging, and controlled command execution (including browser debugging).
- Multi-backend model support and hosting options: works with cloud providers, curated model packs, and self-hosted local modes.
Use Cases
- Implementing large features, refactors, or cross-file fixes in sizeable projects.
- Automated debugging and repair of build, lint, and test workflows.
- Team workflows for branch exploration, diff review, and model-assisted code generation.
Technical Highlights
- Implemented primarily in Go with a CLI (
plandex/pdx) and optional server modes; supports Docker local mode and Plandex Cloud. - MIT licensed and documented with examples and hosted docs for quick onboarding.
- Provides curated model packs, context caching, and multi-model orchestration for cost and latency optimization.
