Plandex (plandex)

Plandex is an open-source, terminal-based AI coding agent designed to take on large, multi-step software development tasks across many files in real-world codebases. Written in Go and released under the MIT license, Plandex builds and executes long-running "plans" — durable, branchable units of work that combine intelligent context management, tree-sitter project maps for 30+ programming languages, an effective 2M-token context window, and a cumulative diff review sandbox that isolates AI edits until a developer explicitly applies them. The tool ships as a CLI with an interactive REPL (fuzzy auto-complete), supports automated debugging of terminal commands and browser applications, integrates with Git for branching and commit-message generation, and is provider-neutral. The Plandex Server exposes a REST management/orchestration API (60+ endpoints) that powers both the CLI/REPL and the hosted Plandex Cloud. Plandex Cloud is winding down as of 2025-10-03; Plandex is now primarily a Docker-based self-hosted / local-mode product.

APIs

Plandex Server API

Management and orchestration REST API exposed by the Plandex server (open-source, Go) used by the Plandex CLI/REPL to drive long-running coding plans across organizations, projects, plans, branches, context, conversation, model packs, and configuration. The same API powered Plandex Cloud (winding down 2025-10-03) and now powers self-hosted / local-mode deployments via Docker. Default local-mode bind is http://localhost:8099.
