CodART vs OpenProperty

CodART is a toolkit for automated refactoring and multi-objective optimization of Java source code. It documents 47 refactoring operations, including Extract Class, Move Method, and Encapsulate Field, and supports project-level and batch work. Its optimization uses NSGA-II and NSGA-III across eight QMOOD quality metrics. The toolkit also includes PPO-based generation of refactoring sequences and models that predict testability from source code metrics. PMD integration with custom rulesets supports code smell detection, while SciTools Understand handles code parsing and metric computation. The documented interfaces are a React web interface and a FastAPI REST API, and Docker Compose instructions explain how to run the services locally. CodART is free under an MIT License, which permits use, copying, modification, distribution, sublicensing, and sale subject to its conditions. The setup requires a separate SciTools Understand professional license; academic licenses are available for research purposes. The quick-start calls for at least 8 GB RAM and 4 CPU cores, with 12 GB or more recommended for large projects. Java is its listed supported language.

OpenProperty is open-source property management software for landlords, small property managers, and apartment or multifamily back-office teams. It manages properties and units, tenants and leases, rent collection records, a ledger, maintenance work orders, and vendors. The dashboard shows occupancy, active leases, outstanding rent, open work orders, and upcoming lease expirations. The ledger generates monthly charges for active leases and records payments by amount, method, date, and reference. Work orders can link properties, units, and vendors while tracking priority, status, scheduled date, and cost. Units record bedrooms, bathrooms, square footage, market rent, and vacant, occupied, turnover, or unavailable status. The project is self-hostable, so users can deploy their own copy and own the data. Deployment uses the Clawnify CLI or Cloudflare Workers and D1. OpenProperty uses the MIT license and is designed without third-party SaaS dependencies or public-facing endpoints. It has no online rent collection, tenant portal, mobile app, team collaboration, listing syndication, screening, messaging automation, or online card and ACH processing.
