What is Plandex?
Plandex is a free, open-source AI coding engine designed around terminal-based work. It helps programmers pursue complex software tasks by using long-running agents that break multi-file, multi-step goals into smaller pieces and continue through them.
Developers can bring project files or directories into the working context, review accumulated changes, and explore alternative approaches before applying them within an ongoing project. The tool is aimed at people handling backlogs, unfamiliar technologies, and repetitive implementation work.
Key features of Plandex
Complex Task Decomposition
Plandex breaks multi-file development goals into smaller tasks, then works through planning, coding, completion, and review activities.
Sandboxed Change Review
Changes accumulate in a protected sandbox, allowing developers to inspect results before applying them and revisit alternative solutions.
Project Context Management
Users can add individual files or whole directories from the terminal, keeping project context available as work continues.
Terminal Multiplatform Runtime
Plandex uses a terminal-centered interface and can run across Mac, Linux, FreeBSD, and Windows environments.
