What the Community Says

Developers are praising Zerostack for its efficiency and security features. As one user noted:

I absolutely like this. Pi becomes sluggish after installing a couple of extensions. I myself was trying to port Pi to Rust but it was consuming too much tokens.

Another user appreciated the lean RAM footprint:

RAM footprint: ~8MB on an empty session, ~12MB when working. I like this, Claude Code is using multiple gigabytes, which is really annoying on lowend laptops

The community is also exploring the possibilities of creating extensions and custom tools with Zerostack.

Security and Configurability

Developers are also drawn to Zerostack’s configurability and security features. One user noted:

Thanks, I’ve been tooling away in my spare time on my own version of this — both to get a deeper understanding of agents and to help learn Rust. I’d like to retain `pi`’s configurability though, the ability to self-mutate and generate new tools is incredibly useful.

The codebase has also been reviewed for security risks, with one user stating:

The codebase was small enough that I handed it over to DeepSeek v4 Flash in Pi to skim through for any risky business, and I didn’t find anything concerning. Nice work.
