I'm a contributor to Claude Code Rust, a Rust reimplementation of Anthropic's Claude Code CLI. I switched to it as my daily driver because upstream Claude Code crashes with JavaScript heap OOM in long sessions (anthropics/claude-code#1421 (
https://github.com/anthropics/claude-code/issues/1421), 65+ comments). The Rust port doesn't have a V8 heap, so the failure mode goes away.
