hey @mattpocockuk β your GitBull developer stock is $19,448 β²3235% this week π
you were shipping hard
check your profile: https://t.co/7xg1KSwfvQ
every dev price = BASE + MOMENTUM
BASE = followers Γ weight + total stars Γ weight + repos
MOMENTUM = this week's commits + new stars + new followers
ship more code = price goes up π’
go quiet = price drifts down π΄
prices reset every monday
I built a stock exchange for GitHub developers π
every dev has a real price based on their actual activity β commits, stars, followers
prices update every monday
10,000 devs listed. find yours π

built GitBull in 4 days with Claude Code
day 1: FastAPI + Firebase skeleton
day 2: price formula + 10k devs populated
day 3: Flutter frontend live
day 4: 3D candlestick market in Three.js
idea β live product in 96 hours
here's how the price formula works π§΅
this is what 10,000 GitHub developers look like as a stock market
each candle = one developer
height = their price
gold ones in the middle = top devs
you can fly through it π

@Linus__Torvalds : $3,003 β²334%
@karpathy : $690
@sindresorhus : $707
what's yours?

@DietrichGebert - $DIETRICHGEBERT is trading at $38627 on GitBull β² 7066.4% this week. Every GitHub dev has a stock price β https://t.co/D4ao8hXGQt
the 3D view is insane
10,000 developers rendered as live candlesticks. gold ones in the middle = top devs by price
you can fly through it

Posted in a QA subreddit today. Got: "AI slop", "ur the problem", 5 upvotes on "no one cares."
Same week, same product: a stranger called the timestamps "spot on."
Channel fit is real. The product didn't change between those two rooms. π

Day 6: @Behavr_AI asked r/QualityAssurance to break my Playwright generation feature.
Scariest post yet β QA engineers are professionally trained to find what's wrong. π
Exactly the feedback a solo founder needs.

A stranger on Reddit tried @Behavr_AI on workout form videos.
His words: "the timestamps were spot on."
I built this for coding tutorials. Users are already finding use cases I never planned.
Lesson: ship it, then let users tell you what you built. π

Week 1 of launch: @Behavr_AI
Day 2: NSFW upload β moderation gate
Day 3: 1 AM injection probes β hardened endpoints
Day 4: Bot hammers API β quotas + rate limits
Attackers taught me more than users did. π

@sridharfyi I'm building BEHAVR β developers
upload coding tutorials and can
ask "where was the JWT setup?"
instead of scrubbing through
45-minute videos. Already live at
https://t.co/ZGImgx073t, built solo in 15 days.
$25K goes into developer outreach
and cross-video intelligence.
Day 5 of launch: shipped a content moderation gate + hardened my feedback endpoint.
Why? My first organic signup uploaded NSFW content. Then someone probed my forms with injection tests at 1 AM.
Nobody warns you: launch week isn't marketing. It's combat training.π
