Capcom RE:Dox, open source serialization/deserialization for game engines

Capcom has released RE:Dox, an open-source, high-performance serialization/deserialization engine for .NET that serves as a core component of their next-generation game engine. The token-based system supports multiple formats including JSON, CBOR, MessagePack, TOML, XML, and others, while achieving significantly faster performance than System.Text.Json—up to 1.8x faster sequential deserialization and 2.8x faster parallel deserialization—with lower memory allocation. RE:Dox combines the speed of tape DOM parsing, the editability of node DOM, and the flexibility of traditional serializers in a unified format-agnostic framework.
