oh-my-pi vs pi-from-scratch

oh-my-pi: oh-my-pi (omp) is a terminal coding agent forked from Mario Zechner's Pi, with LSP operations wired into every write, a real debugger over DAP, persistent Python and Bun kernels, and first-class subagents. It supports 60+ providers, and much of its tooling runs in-process from a Rust core.; pi-from-scratch: PI from Scratch is a Chinese-language article that rebuilds a minimal version of the pi coding agent, called nano-pi, in TypeScript. The companion site fills in the code alongside the text and offers a step-through trace of the execution flow.
