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.
Key Points
- 1Built ScubaDuck end-to-end using vibe coding with OpenAI Codex, completed in three days part-time
- 2Reduced friction for unfamiliar stacks by generating Python server and custom JavaScript UI without external libraries
- 3Enables rapid side-projects and asynchronous work patterns; tests and iterations handled via iterative prompts
Scoring Rationale
Practical demonstration of vibe coding with concrete setup and tests, but single-author anecdote limits generalizability.
