CrateFlow: Rust Monorepo Optimizer

Developers of large Rust projects struggle with sprawling justfiles and dozens of shell scripts that make it nearly impossible to split crates or manage dependencies across a monorepo. CrateFlow provides a graph‑aware interface and automated dependency unification that lets teams cleanly separate crates, streamline testing, and release OSS components with minimal friction.

Comment on: Show HN: Cargo-rail: graph-aware monorepo tooling for Rust; 11 deps

Hey. Author here.I wrote a longer post about the motivation and design: https://dev.to/loadingalias/cargo-rail-making-rust-monorepos...The Problem:I've been working on a low-level Rust workspace for a while now. Before I knew it, my 'justfile' was over 1k lines and I had 30 shell scripts for testing. My dep graph was WAY too large. I couldn't easily split a single crates, or a few crates to release as OSS repos... I'd have had to use Google's Copybara (Java tooling or their GHA) or a mountain of 'git subtree' and filter scripts.The Solution:- Dependency Unification: I use Cargo's resolver outp
