In their own words
BrontoSource
BrontoSource is a desktop tool for deterministic C++ refactoring across large repositories. Teams define explicit transformation rules and apply them across thousands of files. Documented operations include expression matching, extraction, and inlining for functions, constructors, type aliases, enumerators, namespaces, macros, declarations, types, and lambda captures. The command-line tool accepts Clang arguments, a compilation database, or compile_flags.txt, then can generate Fossil-format edits, merge edit files, and apply changes. BrontoSource describes its output as repeatable, traceable diffs for review. Its homepage reports 100M+ lines transformed safely and 10,000+ files refactored in one transformation. The product is in early access, with access arranged through BrontoSource; its API can also be tried on Compiler Explorer without installation. Pricing is on request. A header-only support library supports CMake 3.10.0+ and Bazel 8.1.1+ and uses 0BSD.
OpenProperty
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.
