Bazel 8 made Bzlmod the default and remote execution is effectively standard. Buck2 was rewritten in Rust and went OSS. Pants 2 is the de-facto Python monorepo. In JS-land Nx 20 and Turborepo 2 split the market, and Moon stakes out a Rust-based polyglot niche. Plus Gradle 8.10, Maven 4, Cargo workspaces, Mise, just, Task — all in one piece.

Bazel 8은 Bzlmod이 기본이고 원격 실행이 사실상 표준이 되었다. Buck2는 Rust로 다시 쓰여 사내 도구에서 OSS로 풀렸고, Pants 2는 Python 모노레포의 사실상 표준이다. JS 진영에서는 Nx 20과 Turborepo 2가 양강 구도로 자리잡았고, Moon이 Rust 기반으로 폴리글랏 영역을 노린다.
