GitHub Wrapped, but offline and for any repo, from your terminal

You know "Spotify Wrapped." You've probably seen "GitHub Wrapped" clones too — the ones that make you log in with OAuth, hit the GitHub API, and hand a web app your account so it can tell you how many commits you pushed last year.

Here's a different take: a wrapped that runs entirely in your terminal, works on any git repo (not just yours, not just GitHub), needs no login, no API token, and no network at all. It reads the one thing that already has all the answers — your local git history.

pipx install gitfault
gitfault wrapped

That prints a colorful recap card in your terminal, and with --svg it writes a self-contained, screenshot-ready image you can drop in a README or share:

Why the terminal, and why offline?

The stats that make these cards fun — total commits, active days, longest streak, busiest month, night-owl percentage, top contributors — don't live in some API. They live in git log. Every clone you already have on disk contains the full authorship and timestamp record. So there's no reason to round-trip through a web service to compute them.

That also means you can point it at repos you don't own:

gitfault wrapped -C pallets/click          # clones + recaps a public repo
gitfault wrapped --year 2024               # a specific calendar year
gitfault wrapped --all-time                # the whole history
gitfault wrapped -C . --svg year.svg       # write a shareable card

How the stats actually come out of git

The whole thing is a structured read of git log. A single machine-readable pass gives you author, timestamp, and per-commit line churn:

git log --all --numstat --date=raw \
  --pretty=format:'%H%x09%an%x09%ad'

From that stream you can derive everything on the card without any heuristics you couldn't explain:

• Active days / longest streak — bucket commit timestamps by calendar day, then walk the sorted set of days looking for the longest consecutive run.
• Busiest month — a histogram over YYYY-MM.
• Night-owl % — share of commits whose local hour is before 5 a.m. (a surprisingly durable fingerprint of a project's rhythm).
• Top contributors — group by author, rank by commit count, and you have the little stacked bar at the bottom of the card.
• Lines added — sum the + column from --numstat.

No scraping, no rate limits, no "please authorize this app." Just arithmetic over data you already have.

The card is the point

The reason to emit an SVG rather than only pretty-print is that a recap is only fun if it's shareable. The SVG is a single file with no external fonts or images, sized 1200×630 so it previews cleanly when linked. Render it, screenshot it, or embed the file directly — it's the same artifact either way.

If you want the deeper, less-cheerful side of the same git history — ownership silos, change-coupling between files, and a bus-factor-aware health score — that lives in the other gitfault commands (overview, hotspots, coupling, badge). But wrapped is the one you run on a Friday to see what your repo's year actually looked like.

Neat approach - pulling all of this straight from local git log instead of the API is the right call. One thing worth double-checking: since you're using --date=raw, each commit comes with its own timezone offset from when it was made. If "night-owl %" is computed by converting to your local time rather than applying each commit's own offset, contributors in different time zones (or just people who've changed their system clock) will show skewed results. Worth verifying which one gitfault does - could change the "busiest month" and streak numbers too if commits near midnight get shifted to the wrong day.

Great catch, and you were exactly right. gitfault was reading history with %at (epoch, so effectively UTC), which meant a 9pm-Pacific commit got bucketed as an early-morning "night owl", and commits near midnight could slide onto the wrong local day — skewing streaks and busiest-month too.

I switched it to %aI (strict ISO-8601 carrying each commit's own UTC offset) and parse it preserving that offset, so hour-of-day / night-owl / per-day streaks / busiest month now all reflect the author's local wall-clock time. Shipped in v0.7.1 with a regression test. Thanks for digging into the mechanics — genuinely useful report.
