Fory C++ Serialization – Polymorphism, Circular Refs, 12x vs. Protobuf

Show HN: First IDL for Object-Graph Serialization (Apache Fory IDL)

Fory C++ Serialization – Polymorphism, Circular Refs, 12x vs. Protobuf is a company in show hn launch.

Profile

Apache Fory Schema IDL is the first cross-language schema that treats object graphs (shared refs, cycles, polymorphism) as a first-class contract and still generates idiomatic domain models.1. `ref` encodes shared identity/loops in the schema (weak refs supported) — no manual ID stitching2. `union`/`any` give reusable polymorphism; same semantics across Java/Python/Go/Rust/C++/C#/Swift3. Generated types are real domain models (POJOs, dataclasses, structs, enums), not transport wrappers4. Compatible evolution: field-id matching, defaults, unknown-field skip5. One `.fdl` → compatible bytes across all supported languagesTry it in 60 seconds:```bash pip install fory-compiler foryc ecommerce.fdl

Fory C++ Serialization – Polymorphism, Circular Refs, 12x vs. Protobuf is positioned in show hn launch, a segment that rewards a clear, focused offering.

Its current recorded stage is Show HN launch.
