Plane is an open-source, self-hosted project management platform that provides issue tracking, sprint planning (cycles), modules, pages (wiki), views, analytics, and real-time collaborative editing. The repository is a monorepo containing a Django REST API backend with Celery workers, multiple React frontends (main web app, public space app, admin panel), and a Hocuspocus-based live collaboration server. The architecture follows a service-oriented pattern with shared packages for UI components, editor extensions, types, utilities, and state management via MobX. The codebase demonstrates strong engineering practices with a rich filter system, extensible permission model, and a clean exporter pattern, though it shows signs of ongoing migration from Next.js to React Router and some code duplication across apps.
This repository is a comprehensively governed, production-grade library of 115+ prompt templates, meta-prompt generators, workshop guides, and structured routines for AI-assisted product management. It is not a deployed software application but rather a content methodology repository with application-like engineering discipline: standalone prompt contracts, coupling levels, CI-validated metadata, deterministic catalog generation, and an explicit coupling remediation plan. The library covers the full product management lifecycle—discovery, strategy, requirements, competitive intelligence, end-of-life, storytelling, and team facilitation—using three defined interaction modes (facilitation, co-construction, autonomous investigation). Notable sub-collections include an eight-discipline market intelligence framework (OSINT, FININT, GEOINT, etc.) with an all-source fusion prompt, a complete product sunset (EOL) workflow, and a TAM-SAM-SOM market sizing Langflow pipeline. The repo exhibits hybrid character: while primarily a content asset, it includes reusable Python scripts for validation and catalog generation, a GitHub Actions CI pipeline, and follows software engineering best practices such as versioning, changelogs, and architectural decision records.
