  title: Plandex Server Accounts Models API
  description: 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.
