ZeroBrew: A Drop-In Replacement for Homebrew That's 5x Faster

If you’re a macOS developer, you’ve probably spent more time than you’d like watching Homebrew’s progress bars crawl across your terminal. Package managers are essential, but sometimes the wait for updates or installs can feel like a bottleneck in your workflow. What if you could keep the same simple commands but get your packages in a fraction of the time?

Enter ZeroBrew. It’s a new, experimental package manager that aims to be a direct, drop-in replacement for Homebrew. The main attraction? It claims to run up to five times faster for common operations. For developers who value a quick terminal, that’s a promise worth checking out.

What It Does

ZeroBrew is a CLI tool built in Rust that mimics Homebrew’s core commands. You use it the same way: brew install, brew upgrade, brew list. The key difference is under the hood—it’s designed from the ground up with performance as a primary goal. It handles the same package management tasks but tries to do so with significantly less overhead and delay.

Why It's Cool

The obvious cool factor is the raw speed. A 5x performance boost on operations like installing or updating packages can turn a coffee-break wait into a few seconds. But the clever part is how it achieves this while aiming for compatibility.

It’s built in Rust, which brings inherent performance and safety benefits. The project also seems to focus on a leaner implementation, potentially avoiding some of the legacy code or design decisions that can slow down older tools. It’s not trying to reinvent the wheel or add a million new features; it’s trying to make the existing wheel spin much, much faster. For developers who are deeply familiar with Homebrew’s workflow, that "drop-in" aspect is crucial—it means you can try it without having to learn a new syntax or change your habits.

How to Try It

Ready to give it a spin? The project is on GitHub. Since it’s experimental, make sure to read the current documentation for the latest install instructions and known limitations.

Head over to the repository: github.com/lucasgelfond/zerobrew

You’ll find the source code and installation instructions there. The typical process will likely involve cloning the repo and building it, or using a provided install script. As always, it’s a good idea to test it in a safe environment first.

Final Thoughts

ZeroBrew is a fascinating project that tackles a very specific, very relatable pain point. The idea of a faster Homebrew is incredibly appealing for anyone who uses it daily. While it’s still early days and you should probably not replace your primary Homebrew installation just yet, it’s exactly the kind of ambitious, performance-focused tool that pushes ecosystems forward.

It’s worth watching, contributing to, or just trying out on a secondary machine to see if the speed gains match the hype. If they do, it could become a serious contender for your package manager slot.

What do you think? Would you switch for a 5x speed boost?
