Bun's Rust Rewrite Progresses, Deployed in Claude Code

Source: original article

How is the Bun Rewrite in Rust Going? I think it’s important to be very Canny when someone makes a claim that supports a company’s large valuation. The Bun rewrite seems well positioned as proof-positive that AI and specifically Anthropic’s AI can do the work of open-source maintainers, for some money, but faster. On the 8th of July 2026 Jarred Summner of Bun fame posted about “Rewriting Bun in Rust” . At the time, I felt pretty Canny, having already read about Anthropic’s C compiler and Cursor’s FastRender web browser.
