Developer Builds ScubaDuck With Vibe Coding
|
7.1
On June 2, 2025, an engineer describes building ScubaDuck — a lightweight reimplementation of Meta’s Scuba — entirely via vibe coding using OpenAI Codex, completing the Python server and JavaScript frontend in three days part-time. The project used about 150 prompts, no third-party JavaScript libraries, hermetic environment setup, and automated tests. The case study argues vibe coding reduces cost for side projects and unfamiliar stacks.
