Open-source alternatives to Ifacemaker

Jennifer is a code generator for Go

Tools to let you use Roslyn-powered C# scripts for code generation. You can think of it as a scripted alternative to T4 templates.

sqlc is a SQL compiler and code generator that creates type-safe database client code from raw SQL queries. It transforms SQL statements into typed definitions and functions, eliminating the need for manual row mapping between database results and application structures. The tool ensures compile-time safety by validating SQL queries against the database schema before the application is run. This workflow integrates the database schema directly into the application code, deriving types from the underlying SQL definitions to prevent runtime errors. The system utilizes AST-based query analysis

The Uno source generator is an API compatible source generator inspired by Roslyn v2.0 source generation feature, and an msbuild task which executes the SourceGenerators.
