5 ROUNDS

HOW THE BEEF
WENT PUBLIC

From first Zig commit to a full-contact blog exchange.

  1. THE FIRST BET

    Sumner writes his first line of Zig, then bets Bun’s original runtime on it.

  2. THE BREAKOUT

    Bun grows into a runtime contender. Sumner credits Zig and backs its foundation.

  3. THE REWRITE

    64 Claudes spend 11 days translating Bun to Rust at a claimed $165K in API-equivalent cost.

  4. THE MANIFESTO

    Bun makes the case for Rust with safer cleanup, a mechanical port and 128 reproduced bug fixes.

  5. THE COUNTERPUNCH

    Kelley answers with code-quality accusations, a fuzzing challenge and a defense of Zig’s philosophy.
