TLDR

In an Oct. 2, 2026 X post, Capcom R&D said it publicly released RE:Dox as open-source software. Capcom’s GitHub README describes the.NET library as part of REX technology for the RE ENGINE, and says its benchmark gains over System.Text.Json apply to the listed test datasets rather than serving as universal performance guarantees.

Capcom R&D said in an Oct. 2, 2026 X post that it publicly released RE:Dox as open-source software.

In the project’s GitHub README, Capcom describes RE:Dox as a data representation and serialization foundation library for .NET, and as one of the core components of its next-generation REX technology for the RE ENGINE.

What Capcom says RE:Dox does

According to the README, RE:Dox is built around a shared token-based structured data system that Capcom says can handle reading, editing, format conversion, serialization, deserialization, and automatic parallel deserialization across multiple formats.

The same README says the core package ID is CAPCOM.REDox and that the project is Apache-2.0 licensed in the repository documentation.

The benchmark claims, with Capcom’s caveat

In the README, Capcom says RE:Dox delivered up to about 1.8x faster sequential deserialization, up to about 2.8x faster automatic parallel deserialization, and up to about 1.6x faster serialization than System.Text.Json on the benchmark datasets it listed.

Capcom also says those ratios describe the benchmark datasets shown in the repository and are not universal performance guarantees.

For now, the clearest verified details are Capcom’s announcement post, its description of where RE:Dox fits into REX technology for the RE ENGINE, and the repository’s own license, package, and benchmark notes on GitHub.
