OpenProperty vs Spoon

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.

Spoon is a free, open-source library for analyzing, rewriting, transforming, and transpiling Java source code. It parses source files into an abstract syntax tree (AST), then exposes APIs for inspecting and changing that model. Processors can perform source-level static analysis on selected AST element types, while architectural rules can be expressed as AST checks and run as JUnit tests in continuous integration. Transformation facilities cover instrumentation and refactoring, including helpers for local and generic variables and removing deprecated methods. Spoon can also provide shared analysis of binary and source code through CtClass objects as an alternative to Java reflection. The project supports Java source up to Java 25, but runtime requirements vary: Spoon 11.x needs JDK 17 or later, 10.x needs JDK 11 or later, and 9.x needs Java 8. It is available through Java, the command line, Maven, and Gradle, with a dependency JAR on Maven Central. Command-line use requires manual classpath handling and source dependencies specified with --source-classpath. Spoon is an official Inria project and an OW2 consortium member.
