PUBLIC GITHUB ACTIVITY, MADE VISUAL
Coder Cards turns public GitHub activity into a colorful, explainable snapshot of how you build.
The card
Your GitHub, as a collectible.
Twelve tiles, one persona — built from your real commits. This is an actual card from the app, not a mockup.
Persona + tagline
The headline of your card.
Your local hours
Peak hour and weekly rhythm in your timezone.
Real tech stack
Measured from lines you changed.
Character stats
Five axes, scored 0–100.
Inside the card
One card. A surprising amount of signal.
Every tile turns a small, explainable pattern in public GitHub activity into something you can explore and share.
Card tile
Code signals
Style findings, identifier patterns, source-file structure, testing activity, guard clauses, exception handling, and whitespace patterns.
How it’s calculated
Signals are sampled from changed public source lines and summarized as explainable observations.
How it Works.
01
Connect public GitHub
Connect your public GitHub account to start building a card from activity you choose to share.
02
We collect a sample
We collect a sample of public activity and commit changes to surface explainable signals.
03
Your Coder Card is ready
Explore the patterns, keep the snapshot, or share your card with others.
04
Share your card
Copy the image, copy your link, download a PNG, or post straight to X or Reddit.
Scores are heuristics over a collected sample, not a code review.

Apparently I’m The Clean Coder. 98% style score, 25% testing… we don’t talk about testing.
What’s coming
Coder Cards is the visual preview of a broader developer-style system.
Bring the developer-style profile behind your card into your coding workflow.
• Style-aware generation shaped by preferred naming, formatting, structure, and documentation patterns.
• A style profile that considers visual, architectural, cognitive, and behavioral code patterns.
• A controllable style-adapter layer—not a claim to replace an IDE, code review, or Copilot.
Join early access →Deeper personal coding profiles and more useful ways to carry them between workflows.
Team-level style context and shared conventions.
A visual, explainable way to discuss different coding patterns and styles.
What a card is—and isn’t.
Public activity only
Coder Cards uses public GitHub information and collected public repository activity.
Explainable signals
Each card metric can be traced to specific inputs and a plain-language explanation.
A snapshot, not a judgment
The card is a playful, heuristic view of a collected sample—not a code review or professional assessment.

What is Coder Cards?
An absolutely free app that turns your public GitHub activity into a colorful, shareable card — your persona, rhythm, tech stack, style score, and more. This page is the intro; the card is made in the app.
Do I need an account?
No separate account. You sign in with GitHub inside the app.
What data does it use?
Your public GitHub activity: commit timestamps, commit messages, repository metadata, and the patches from a random sample of your commits. Private repositories are never accessed.
How long does it take?
Most cards are ready quickly. Big profiles can take a couple of minutes — the analysis keeps running and your card appears when it’s done.
Why does the app ask for my timezone?
GitHub stores commit times in UTC. Your timezone lets your Peak Hour and Weekly Rhythm reflect the hours you actually keep.
How accurate are the scores?
They’re heuristics over a sample of your commits, not a code review. Style, naming, and structure metrics are tuned for Python and JavaScript.
Can I share or download my card?
Yes. From the Share panel under your card you can copy the image, copy your link, download a PNG, or post to X or Reddit.
Can I update my card?
Yes. Hit Refresh on your card to re-run the analysis with your latest activity.
What’s your coding persona?
Open the app, sign in with GitHub, and get your card in minutes.
Public activity only. We never access private repositories.
