Claude Code v2.1.181 and later utilize the Rust port of Bun, resulting in a 10% faster startup on Linux. The command `strings ~/.local/bin/claude | grep -m1 'Bun v1'` confirms the use of Bun v1.4.0 on macOS.

Roc's compiler team has rewritten 300,000 lines of Rust code into Zig over the past year and a half. The project has achieved feature parity with the original Rust compiler.

Bun is being rewritten in Rust to improve performance and maintainability. Jarred's early involvement in the Zig community showcased his experimental approach to problem-solving, contributing to his growth as an engineer.

pgrust is a rewrite of Postgres in Rust that achieves 100% compatibility with Postgres 18.3, passing over 46,000 regression tests. It maintains disk compatibility with Postgres and can boot from an existing Postgres 18.3 data directory, aiming to facilitate internal changes while preserving the original behavior and using AI-assisted programming.

Prylint is a Rust reimplementation of pylint that delivers byte-for-byte identical output while being 15 to 2300 times faster, with a median speed increase of approximately 85 times. It maintains the same error messages, line and column references, text order, exit codes, and footer as the original pylint.

React Compiler is being ported to Rust as an experimental project. The port is in progress, with all fixtures passing but potential unknown bugs, and no builds are currently available for testing.

Grit is a project aimed at rewriting Git in Rust, focusing on creating a library-based architecture. The initiative draws inspiration from Anthropic's experiment with agents generating a functioning C compiler.

Bun has transitioned to Rust with over a million lines of code and 6,755 commits, primarily generated by Claude Code agents in nine days. The previous Zig implementation has been removed following Anthropic's acquisition of Bun in December.

A project originally written in Rust, consisting of approximately 30,000 lines of code, is being revisited with an interest in Ruby and Ruby on Rails. Ruby and Ruby on Rails continue to perform well in the current programming landscape.
