PI-mono (by Mario Zechner / badlogic) is the UnJS of coding agents! Simple, composable, provider-agnostic, and extendable*. It powers OpenClaw!
*The crazy part? It can write code to extend itself and become exactly the coding agent you want! 🤯
Plus, it is called pi, and I'm pi0 😄

The future is software writing its own software. Which is why I'm so in love with Pi: a coding agent that can extend itself :) lucumr.pocoo.org/2026/1/31/pi/
Pi: The Minimal Agent Within OpenClaw
A gentle introduction to the Pi coding agent and why I think it’s a glimpse into the future of software.

Not long ago, a PC with 4 MB RAM, a 500 MB HDD, and a 60 MHz CPU was pretty normal.
Today, LLMs have tight resources, limited context and memory and are slow and expensive to run.
Our kids will laugh at this era.
For now, we work around the limits until we get there!

🛡️ We fixed a bug in H3 v1 where a specific Transfer-Encoding header could cause the readBody to ignore the request body. This could enable request smuggling when running behind L4 TCP load balancers or non-normalizing proxies.
Fixed in latest H3, Nitro and Unstorage.

Open libraries in @unjs.io and H3.dev power millions.
Maintenance is tough and largely unmanned compared to the projects built on top of them.
Huge thanks to the silent, selfless heroes who fix issues before I even notice them. You’re the reason I still keep doing open source. ❤️
