Define the schema then generate idiomatic, type-safe code (Python, Go, Java, Rust, TS, etc). Dynamic serialization options e.g. binary or JSON. VS Code extension & LSP tooling. Supports backwards compatibility when changing schemas.
Compile-time errors if you add a field, but don’t regenerate the code - this is the opposite to protobuf which handles it by defaulting values. This may be better, depending on your philosophy.
Based on Console’s review published on 2026-04-09. Summary updated .
Developers working with multiple programming languages should consider Skir
Skir allows generating type-safe code from a schema definition
Skir requires regenerating code after schema changes to avoid compile-time errors
Checked
Schema compiler generates TypeScript, Python, Java, Kotlin, Rust, Go, Swift and Zig; Elixir generator is community-maintained.
