OpenProperty vs OpenRewrite

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.

OpenRewrite is an open-source ecosystem for automated code refactoring, aimed at updating code and reducing technical debt. It represents code as Lossless Semantic Trees, applies transformations, and prints the result back into source code for review. Its recipes cover framework migrations, security fixes, and style consistency, and can be written in YAML, Refaster templates, or Java. Maven and Gradle plugins run recipes locally as part of builds, one repository at a time. The Maven plugin offers a dry run that reports potential changes and writes diff files; recipes run only when explicitly activated by name. Documented support includes Java, Kotlin, and Groovy, plus formats such as HCL, JSON, Properties, Protobuf, TOML, XML, and YAML. Framework coverage includes Spring, Quarkus, and Micronaut. The recipe index lists 4,183 recipes across modules. Core and language libraries use Apache License 2.0, but some recipes have other licensing terms. Core is free; some artifacts require authenticated repository access, and some recipes require a Moderne subscription.
