🚀 Build Your Own X with Vibe Coding

September 5, 2025 · View on GitHub

What I cannot create, I do not understand — Richard Feynman.

Use Vibe-Coding to make “from-scratch” building faster, smoother, and more fun.

This repo preserves the spirit of build-your-own-x, and upgrades the workflow for the LLM era:

  • Vibe-Coding = short iterative loops + lightweight prompt recipes + runnable scaffolds + tiny wins.
  • LLMs in the loop: prompt recipes, debug diaries, and auto-checks live alongside the code.

What is Vibe-Coding?

A pragmatic build style:

  1. Micro loops (15–25 min): set one tiny goal → build → run → jot what felt off (the “vibe”).
  2. Prompt recipes: reusable 10–15 line prompts for planning, refactors, tests, and perf hints.
  3. Scaffolds over specs: start from minimal templates; ship something runnable ASAP.
  4. Reality checks: each step ends with an auto-runnable check (script/notebook/test).
  5. Build diary: keep a vibes.md per project — 1–3 bullets/loop: intent → friction → next.

TL;DR: Less ceremony, more momentum. Learn a bit, run a bit, close the loop.

❤️ Need Your Help !

We’re actively collecting: Community showcases — repos/blog posts that used Vibe-Coding to complete a BYO-X project.

How to submit

Open a PR or issue with:

  • Link(s): repo and/or blog post
  • Vibe artifacts: recipes/*.md (prompts), checks/* (auto-checks), scaffolds/* (minimal runnable)
  • Build diary: vibes.md (3 bullets: intent → friction → next)
  • Notes: compute used, dataset/source, license

How to Use

  1. Pick a topic → open blueprints/<topic>/README.md.
  2. Copy the Prompt Recipes and follow the steps (each section stands alone).
  3. Run the auto-check via checks/<topic>_smoke.* or a small notebook.
  4. Log your loop in vibes.md so you can reproduce & share later.

The Vibe Loop (cheat-sheet)

  • 🎯 Tiny intent: define one win.
  • ✍️ Plan w/ recipe: paste system prompt (plan/refactor/test).
  • 🛠️ Do the thing: code the minimum; prefer a scaffold.
  • ✅ Auto-check: run checks/* and capture the output.
  • 📝 Log vibe: append 1–3 bullets to vibes.md (intent → friction → next).

We love classic “from-scratch” tutorials and Vibe-wrapped upgrades.

For each PR, please include:

  1. One minimal runnable example (script/notebook/app)
  2. line prompt recipe (planning/refactor/test/perf) in recipes/
  3. An auto-check in checks/ (smoke test or small eval)
  4. short bullets from your vibes.md (intent → friction → next)

You can also “Vibe-wrap” any existing entry by adding a tail line under it:
